Mappings are not working when "Enable staging" is checked in ADF copy activity. is there a solution?

@Mario Hassrouty

Welcome to the Microsoft Q&A and thank you for posting your questions here.

When “Enable staging” is checked in Azure Data Factory (ADF) copy activity, it can sometimes cause issues with column mappings. Here are a few steps you can try to resolve this:

Explicit Mapping: Ensure you have defined explicit column mappings in the copy activity. This can be done in the mapping tab of the copy activity settings.

On copy activity -> mapping tab, click Import schemas button to import both source and sink schemas.

Map the needed fields and exclude/delete the rest.

Check Schema: Verify that the schema of the staging blob storage matches the schema of your source and sink. Any discrepancies can cause mapping issues.

Update Integration Runtime: Make sure your integration runtime is up to date, as sometimes updates can resolve unexpected issues.

Alternative Approach: If the above steps don’t work, you might consider using two separate copy activities as a workaround. The first copy activity can move data to the staging blob, and the second can move data from the blob to the SQL server with proper mappings check the below link for detiald information.
