When you generate the ABAP program, you can add authority checks. The Designer adds an authority check to the ABAP program for each Application Source Qualifier in the mapping.

The application server verifies that the user running the workflow has read permission on the sources. If the user does not have authorization to access one of the sources, the session fails with a NO AUTHORITY error.

If you enabled the Authority Check option when you generated the ABAP program, the SAP application server verifies that the user running the workflow has authorization to read the sources. SAP verifies the authorization before it reads the first source. If the user in the SAP ECC application connection does not have read authorization on any one of the sources, the session fails with a NO AUTHORITY error.
