In the Salesforce Field Service (SFS) mobile app, the Inventory section does not include a Return Order tab. This is a current product limitation — adding a custom tab to the Inventory section is also not supported due to technical boundaries of the Field Service mobile app.
Users cannot create a Return Order directly from the Inventory tab. As per the Salesforce product management team, documentation for the Return Order feature is planned for update in an upcoming release.
For reference on how Return Orders are designed to work in Salesforce Field Service:
Although the Return Order tab is not directly accessible from the Inventory section of the Salesforce Field Service mobile app, the following two workarounds allow users to create Return Orders.
In both workarounds, the Return Order must have a parent record — either a Work Order (WO) or Service Appointment (SA) — to appear in the mobile app's related list. Without a parent, the Return Order does not display in the related list.
Return Orders must have a parent record such as a Work Order to appear in the mobile app.
The Return Order then appears in the mobile app under: Work Order > Product Request Related List > Open > Return Order Related List.
You can build a Salesforce Flow that creates a Return Order directly from the mobile app.
Note:
The return order must have a parent associated (WO/SA, and so on) and it will be displayed in the related list (WO> Product Request Related > Open > Return Order related list).
So if you want to create a return order on a product request then that request should have parent linked to either WO or SA.
