Execution problem in GRAC_REPOSITORY_OBJECT_SYNC for Legacy files

Dear SAP experts.

I am trying to perfom a Risk Analysis trhough a Legacy connector.

Additionally, I followed the steps to create the specific file paths described in the manual attached in to SAP Note 1594963.

Nevertheless I have executed GRAC_REPOSITORY_OBJECT_SYNC job and the I have checked SLG1 tcode (see attached snapshot) and it appears a message saying " User Adapter is empty". Furthermore, I have performed it in EN language.

Do you have any clue about this?

Thanks in advance.

Regards.
