Authority check in CO02
I need to perform authority check in the T.Code CO02(Screen : Production order change:Component overviw) for the fields MATNR and MENGE in the list of line items.
System -> Status->
Program (screen) SAPLCOMK
Screen number 120
Program (GUI) SAPLCOCU
GUI status VVKOMP
The user should be restricted to change the Material and quantity in the line items ( T.Code CO02-Production order change : component overview).
For this where should the authority check be done? In which user exit?
I have done the uthority check in the FM : EXIT_SAPLCOMK_006 inside the include : ZXCO1U07 but it is not working.
Can anyone suggest or guide me to the right path to resolve the issue?
Your help will be appreciated.
