Set madatory fields at Investments tab for KO01 / KO02
I want put as mandatory two fields in tab "investments" in transaction KO01 (Create internal Order).
These fields are included in area "Depreciation simulation data"; and they are the field "Asset class" and Capitalization date". The two fields are standar, but I need put them as mandatory.
It is posible modify these fields or check the values at any user-exit?
Thanks in advance
