PSPAR-PLANS in IT0000 screen
My client wants to make change in the screen of IT0000. During the hiring action through PA40, the IT0000 screen comes up 1st, followed by IT0001. In the present setting, Position field has to be populated in IT0000 which is a required field there, and this value gets copied to IT0001. Other values of employee group, sub-group, personnel area, sub-area are taken from Position.
Client wants to make the position field as optional. I know this can be done in the module pool MP000000.
001 P0000-STAT1 Customer-Specific Status
002 Q0000-RFPNR Reference personnel number
003 P0000-STAT3 Special Payment Status
004 PSPAR-PLANS Position
005 P0000-MASSN Action Type
006 P0000-MASSG Reason for Action
But even if I make the Position as an optional field, the IT0000 screen asks values for Per Area, Emp Group, Emp Sub-Group. I am not able to make these fields also as optional as there fields are not there in the module pool MP0000000. Can anybody suggest how I can make all these fields as optional so that IT00000 screen can be used only for recording the Action Type, and the following screen of IT0001 can be used for entering values of Position / ESG/ EG/ PA or PSA.
Thanks for your help.
