+This module allows you to manage `Return Merchandise Authorization (RMA)
+<https://en.wikipedia.org/wiki/Return_merchandise_authorization>`_.
+RMA documents can be created from scratch, from a delivery order or from
+an incoming email. Product receptions and returning delivery operations
+of the RMA module are fully integrated with the Receipts and Deliveries
+Operations of Odoo inventory core module. It also allows you to generate
+refunds in the same way as Odoo generates it.
+Besides, you have full integration of the RMA documents in the customer portal.
+

+
+Configuration
+=============
+
+If you want RMAs to be created from incoming emails, you need to:
+
+#. Go to *Settings > General Settings*.
+#. Check 'External Email Servers' checkbox under *Discuss* section.
+#. Set an 'alias domain' and an incoming server.
+#. Go to *RMA > Configuration > RMA Team* and select a team or create a new
+   one.
+#. Go to 'Email' tab and set an 'Email Alias'.
+
+If you want to manually finish RMAs, you need to:
+
+#. Go to *Settings > Inventory*.
+#. Set *Finish RMAs manually* checkbox on.
+
+By default, returns to customer are grouped by shipping address, warehouse and company.
+If you want to avoid this grouping you can:
+
+#. Go to *Settings > Inventory*.
+#. Set *Group RMA returns by customer address and warehouse* checkbox off.
+
+The users will still be able to group those pickings from the wizard.
+
+Usage
+=====
+
+To use this module, you need to:
+
+#. Go to *RMA > Orders* and create a new RMA.
+#. Select a partner, an invoice address, select a product
+   (or select a picking and a move instead), write a quantity, fill the rest
+   of the form and click on 'confirm' button in the status bar.
+#. You will see an smart button labeled 'Receipt'. Click on that button to see
+   the reception operation form.
+#. If everything is right, validate the operation and go back to the RMA to
+   see it in a 'received' state.
+#. Now you are able to generate a refund, generate a delivery order to return
+   to the customer the same product or another product as a replacement, split
+   the RMA by extracting a part of the remaining quantity to another RMA,
+   preview the RMA in the website. All of these operations can be done by
+   clicking on the buttons in the status bar.
+
+   * If you click on 'Refund' button, a refund will be created, and it will be
+     accessible via the smart button labeled Refund. The RMA will be set
+     automatically to 'Refunded' state when the refund is validated.
+   * If you click on 'Replace' or 'Return to customer' button instead,
+     a popup wizard will guide you to create a Delivery order to the client
+     and this order will be accessible via the smart button labeled Delivery.
+     The RMA will be set automatically to 'Replaced' or 'Returned' state when
+     the RMA quantity is equal or lower than the quantity in done delivery
+     orders linked to it.
+#. You can also finish the RMA without further ado. To do so click on the *Finish*
+   button. A wizard will ask you for the reason from a selection of preconfigured ones.
+   Be sure to configure them in advance on *RMA > Configuration > Finalization Reasons*.
+   Once the RMA is finished, it will be set to that state and the reason will be
+   registered.
+
+An RMA can also be created from a return of a delivery order:
+
+#. Select a delivery order and click on 'Return' button to create a return.
+#. Check "Create RMAs" checkbox in the returning wizard, select the RMA
+   stock location and click on 'Return' button.
+#. An RMA will be created for each product returned in the previous step.
+   Every RMA will be in confirmed state and they will
+   be linked to the returning operation generated previously.
+
+There are Optional RMA Teams that can be used for:
+
+  - Organize RMAs in sections.
+  - Subscribe users to notifications.
+  - Create RMAs from incoming mail to special aliases (See configuration
+    section).
+
+To create an RMA Team (RMA Responsible user level required):
+
+  #. Go to *RMA > Configuration > RMA Teams*
+  #. Create a new team and assign a name, a responsible and members.
+  #. Subscribe users to notifications, that can be of these subtypes:
+
+     - RMA draft. When a new RMA is created.
+     - Notes, Debates, Activities. As in standard Odoo.
+  #. In the list view, use the cross handle to sort RMA Teams. The top team
+     will be the default one if no team is set.
+
+Known issues / Roadmap
+======================
+
+* As soon as the picking is selected, the user should select the move,
+  but perhaps stock.move _rec_name could be improved to better show what
+  the product of that move is.

+#. Go to *Settings > General Settings*.
+#. Check 'External Email Servers' checkbox under *Discuss* section.
+#. Set an 'alias domain' and an incoming server.
+#. Go to *RMA > Configuration > RMA Team* and select a team or create a new

+If you want to manually finish RMAs, you need to:
+
+#. Go to *Settings > Inventory*.
+#. Set *Finish RMAs manually* checkbox on.
+
+By default, returns to customer are grouped by shipping address, warehouse and company.
+If you want to avoid this grouping you can:
+
+#. Go to *Settings > Inventory*.
+#. Set *Group RMA returns by customer address and warehouse* checkbox off.
+
+The users will still be able to group those pickings from the wizard.

+This module allows you to manage `Return Merchandise Authorization (RMA)
+<https://en.wikipedia.org/wiki/Return_merchandise_authorization>`_.
+RMA documents can be created from scratch, from a delivery order or from
+an incoming email. Product receptions and returning delivery operations
+of the RMA module are fully integrated with the Receipts and Deliveries
+Operations of Odoo inventory core module. It also allows you to generate
+refunds in the same way as Odoo generates it.
+Besides, you have full integration of the RMA documents in the customer portal.

rma/readme/USAGE.rst

@@ -0,0 +1,57 @@
+To use this module, you need to:
+
+#. Go to *RMA > Orders* and create a new RMA.
+#. Select a partner, an invoice address, select a product
+   (or select a picking and a move instead), write a quantity, fill the rest
+   of the form and click on 'confirm' button in the status bar.
+#. You will see an smart button labeled 'Receipt'. Click on that button to see
+   the reception operation form.
+#. If everything is right, validate the operation and go back to the RMA to
+   see it in a 'received' state.
+#. Now you are able to generate a refund, generate a delivery order to return
+   to the customer the same product or another product as a replacement, split
+   the RMA by extracting a part of the remaining quantity to another RMA,
+   preview the RMA in the website. All of these operations can be done by
+   clicking on the buttons in the status bar.
+
+   * If you click on 'Refund' button, a refund will be created, and it will be
+     accessible via the smart button labeled Refund. The RMA will be set
+     automatically to 'Refunded' state when the refund is validated.
+   * If you click on 'Replace' or 'Return to customer' button instead,
+     a popup wizard will guide you to create a Delivery order to the client
+     and this order will be accessible via the smart button labeled Delivery.
+     The RMA will be set automatically to 'Replaced' or 'Returned' state when
+     the RMA quantity is equal or lower than the quantity in done delivery
+     orders linked to it.
+#. You can also finish the RMA without further ado. To do so click on the *Finish*
+   button. A wizard will ask you for the reason from a selection of preconfigured ones.
+   Be sure to configure them in advance on *RMA > Configuration > Finalization Reasons*.
+   Once the RMA is finished, it will be set to that state and the reason will be
+   registered.
+
+An RMA can also be created from a return of a delivery order:
+
+#. Select a delivery order and click on 'Return' button to create a return.
+#. Check "Create RMAs" checkbox in the returning wizard, select the RMA
+   stock location and click on 'Return' button.
+#. An RMA will be created for each product returned in the previous step.
+   Every RMA will be in confirmed state and they will
+   be linked to the returning operation generated previously.
+
+There are Optional RMA Teams that can be used for:
+
+  - Organize RMAs in sections.
+  - Subscribe users to notifications.
+  - Create RMAs from incoming mail to special aliases (See configuration
+    section).
+
+To create an RMA Team (RMA Responsible user level required):
+
+  #. Go to *RMA > Configuration > RMA Teams*
+  #. Create a new team and assign a name, a responsible and members.
+  #. Subscribe users to notifications, that can be of these subtypes:
+
+     - RMA draft. When a new RMA is created.
+     - Notes, Debates, Activities. As in standard Odoo.
+  #. In the list view, use the cross handle to sort RMA Teams. The top team
+     will be the default one if no team is set.

+<p>This module allows you to manage <a class="reference external" href="https://en.wikipedia.org/wiki/Return_merchandise_authorization">Return Merchandise Authorization (RMA)</a>.
+RMA documents can be created from scratch, from a delivery order or from
+an incoming email. Product receptions and returning delivery operations
+of the RMA module are fully integrated with the Receipts and Deliveries
+Operations of Odoo inventory core module. It also allows you to generate
+refunds in the same way as Odoo generates it.
+Besides, you have full integration of the RMA documents in the customer portal.</p>

+<h1><a class="toc-backref" href="#id1">Configuration</a></h1>
+<p>If you want RMAs to be created from incoming emails, you need to:</p>
+<ol class="arabic simple">
+<li>Go to <em>Settings &gt; General Settings</em>.</li>
+<li>Check ‘External Email Servers’ checkbox under <em>Discuss</em> section.</li>
+<li>Set an ‘alias domain’ and an incoming server.</li>
+<li>Go to <em>RMA &gt; Configuration &gt; RMA Team</em> and select a team or create a new
+one.</li>
+<li>Go to ‘Email’ tab and set an ‘Email Alias’.</li>
+</ol>
+<p>If you want to manually finish RMAs, you need to:</p>
+<ol class="arabic simple">
+<li>Go to <em>Settings &gt; Inventory</em>.</li>
+<li>Set <em>Finish RMAs manually</em> checkbox on.</li>
+</ol>
+<p>By default, returns to customer are grouped by shipping address, warehouse and company.
+If you want to avoid this grouping you can:</p>
+<ol class="arabic simple">
+<li>Go to <em>Settings &gt; Inventory</em>.</li>
+<li>Set <em>Group RMA returns by customer address and warehouse</em> checkbox off.</li>
+</ol>
+<p>The users will still be able to group those pickings from the wizard.</p>
+</div>
+<div class="section" id="usage">
+<h1><a class="toc-backref" href="#id2">Usage</a></h1>
+<p>To use this module, you need to:</p>
+<ol class="arabic simple">
+<li>Go to <em>RMA &gt; Orders</em> and create a new RMA.</li>
+<li>Select a partner, an invoice address, select a product
+(or select a picking and a move instead), write a quantity, fill the rest
+of the form and click on ‘confirm’ button in the status bar.</li>
+<li>You will see an smart button labeled ‘Receipt’. Click on that button to see
+the reception operation form.</li>
+<li>If everything is right, validate the operation and go back to the RMA to
+see it in a ‘received’ state.</li>
+<li>Now you are able to generate a refund, generate a delivery order to return
+to the customer the same product or another product as a replacement, split
+the RMA by extracting a part of the remaining quantity to another RMA,
+preview the RMA in the website. All of these operations can be done by
+clicking on the buttons in the status bar.<ul>
+<li>If you click on ‘Refund’ button, a refund will be created, and it will be
+accessible via the smart button labeled Refund. The RMA will be set
+automatically to ‘Refunded’ state when the refund is validated.</li>
+<li>If you click on ‘Replace’ or ‘Return to customer’ button instead,
+a popup wizard will guide you to create a Delivery order to the client
+and this order will be accessible via the smart button labeled Delivery.
+The RMA will be set automatically to ‘Replaced’ or ‘Returned’ state when
+the RMA quantity is equal or lower than the quantity in done delivery
+orders linked to it.</li>
+</ul>
+</li>
+<li>You can also finish the RMA without further ado. To do so click on the <em>Finish</em>
+button. A wizard will ask you for the reason from a selection of preconfigured ones.
+Be sure to configure them in advance on <em>RMA &gt; Configuration &gt; Finalization Reasons</em>.
+Once the RMA is finished, it will be set to that state and the reason will be
+registered.</li>
+</ol>
+<p>An RMA can also be created from a return of a delivery order:</p>
+<ol class="arabic simple">
+<li>Select a delivery order and click on ‘Return’ button to create a return.</li>
+<li>Check “Create RMAs” checkbox in the returning wizard, select the RMA
+stock location and click on ‘Return’ button.</li>
+<li>An RMA will be created for each product returned in the previous step.
+Every RMA will be in confirmed state and they will
+be linked to the returning operation generated previously.</li>
+</ol>
+<p>There are Optional RMA Teams that can be used for:</p>
+<blockquote>
+<ul class="simple">
+<li>Organize RMAs in sections.</li>
+<li>Subscribe users to notifications.</li>
+<li>Create RMAs from incoming mail to special aliases (See configuration
+section).</li>
+</ul>
+</blockquote>
+<p>To create an RMA Team (RMA Responsible user level required):</p>
+<blockquote>
+<ol class="arabic simple">
+<li>Go to <em>RMA &gt; Configuration &gt; RMA Teams</em></li>
+<li>Create a new team and assign a name, a responsible and members.</li>
+<li>Subscribe users to notifications, that can be of these subtypes:<ul>
+<li>RMA draft. When a new RMA is created.</li>
+<li>Notes, Debates, Activities. As in standard Odoo.</li>
+</ul>
+</li>
+<li>In the list view, use the cross handle to sort RMA Teams. The top team
+will be the default one if no team is set.</li>
+</ol>
