E-Recruiting - user RCF_Service

Hi

We get different log entries in transaction SLG1 for the user RCF_SERVICE. The message says that there is no requisition for this posting. Has it something to do with the legal period definitions, where requisition are deleted after a specific time? How can we clean this entries in the SLG1? Should we reassign the NC object to the appropriate NB object.

Any help is appreciated

Regards
