I never changed period in KKA0 and WIP calculated correctly everytime. But recently my friend told me that they had to change period otherwise they are getting error in PS.
I tried to look explanation but that I could not find. Requesting you please provide your expert comments on following:
1. Why we use change period KKA0.
2.If change every month then what is the impact in case of Process order or by period.
3. What is impact in both case if do not change or not change on montly basis.
