In my project , User status is maintained for WBS.
My client want to Change the User Status of all the WBS when one activity is confirmed .
lets get an example: In project there are WBS A, B and C. In WBS A there are Activity number 1 and 2.
The WBS has user status Z and X. When Activity 1 is confirmed , all the user status of WBS will be Z.
When the acvity 2 is confirmed , all the user status of WBS will be X.
Please help how to do this. is there any enhancement or BAPI.
