+
+This module allows you to create substitution rules for report actions.
+A typical use case is to replace a standard report by alternative reports
+when some conditions are met. For instance, it allows to configure alternate
+reports for different companies.

+
+Usage
+=====
+
+To use this module, you need to:
+
+#. Go to 'Actions' / 'Reports'
+
+#. Select the desired report you want to 'Substitution Rules'
+
+#. In the substitutions page add a new line
+
+#. Select the substitution report action
+
+#. Set a domain to specify when this substitution should happen
+
+
+When a user calls a report action, the system tries to find the first
+substitution in with a domain that matches all records.
+
+Known issues / Roadmap
+======================
+
+- The document name result should take the name of the substitution report.

+<p>This module allows you to create substitution rules for report actions.
+A typical use case is to replace a standard report by alternative reports
+when some conditions are met. For instance, it allows to configure alternate
+reports for different companies.</p>

+<p>To use this module, you need to:</p>
+<ol class="arabic simple">
+<li>Go to ‘Actions’ / ‘Reports’</li>
+<li>Select the desired report you want to ‘Substitution Rules’</li>
+<li>In the substitutions page add a new line</li>
+<li>Select the substitution report action</li>
+<li>Set a domain to specify when this substitution should happen</li>
+</ol>
+<p>When a user calls a report action, the system tries to find the first
+substitution in with a domain that matches all records.</p>
