Diagnosis
To execute the required function, the system determines the employee'spersonnel number based on his or her user ID. The system could not dothis, however, because some personnel master data (
infotype 0105) has notbeen maintained for employee &V1&.

System Response
The system cannot execute the required function.

Procedure
Check table T77S0 for the entry for GRPID 'MAIL' and SEMID 'SAPSY'.
This entry determines which subtype of infotype 105 is used to determinethe system user ID. This is usually subtype 0001.
Now check the entry in the view V_T591C for the subtype determined inthe first step.
In this view, the indicator LONG_ID should not be set for thecorresponding subtype (see Note 504531).
If the customizing settings are correct, create the correspondingcombination of infotype 105 and subtype xxx.
If the indicator LONG_ID was set in view V_T591C and then withdrawn,all data records in infotype 105 for the corresponding subtype must beupdated again.
It should then be possible to runtransaction CATSXT without problems.
