Re: Import Declaration wrt to Returns Delivery ( Customer Returns)

We also tried unsucessfully to apply this flow.

This limitation is confirmed by SAP KB 2064103 - KBA: Import declaration before GR for Return Delivery.

New idea published, please support it if you consider it relevant:

Support of import declaration before GR for Customer Return Delivery : View Idea

In addition, as the settings for creating an import declaration after GR are in my opinion not clearly described, I have requested the creation of a dedicated KB article through idea:
