Error PROG_DEF_S_NOT_INDICATED

Hello experts,

I'm running the following Datasources in ECC (Transaction Code: RSA3) and I'm getting the following error message:

PROG_DEF_S_NOT_INDICATED

Do you know what can be the problem?

I didn't found over the Internet no one with the same problem.

I reaaly need your help on this.

Many thanks.

Thanks in advance.
