Change Planned Working Time in Infotype 0007
Can anyone please help me with this problem I'm having in changing a record in IT0007? I am able to successfully create a record in this infotype with SCHKZ=FULLTIME, ZTERF=0, EMPCT=100, ARBST=8 and WKWDY=5; the rest of the fields I assume are computed by SAP automatically based on these inputs. My problem is that the client wants to vary the value of WKWDY. However, when I try to change WKWDY to 4,6 or any number between 1-7, it defaults this field to 5 again and prompts "No changes found". Isn't there supposed to be a computation for when WKWDY is varied or is it normal for SAP to behave like that? Any help is much appreciated, thanks in advance!
