am trying to set up the concurrent employment in a group where employees have several contracts with many company codes within the group and consequently they have many personnel numbers however I cannot generate the Person ID which is the unique identification for each person. I set the switch in T77S0 to
CCURE PAUIX X CE Master Data User Interface Enhancements
but when I try to set the switch is teh entry CCURE PIDGN the fiels is greyed out and I cannot select from the list.
Is there a prerequisite that I should have done beforehand?
Can anybody help?
