SLG1 error - SERVICE USER no candidate could be found

Hi all,

we find several errors in SLG1 coming from service user for unregistered candidates:

Clik here to view.

1 ----> I've checked SU53 and auth issues, and I think everything is ok.

2 ----> If I'm not wrong service user doesn't have to be linked to a Candidate object.

Do you have any suggestion about what can I check it now?

(I put a trace for SERV_USER....and realized that HRP1001 and PA0105 are accessed with SERV_USER, what I find strange...)

THX!
