I have a requirement where i need to do a validation in FV60/65. Earlier, for a similar requirement for validation at the header level, i have used GGB0 and wrote custom code in the available userexit ( i had made a copy of RGGBR000 and implemented custom code in the copy) and replaced the standard program RGGBR000 in tcode GCX2)
Now, when im trying to implement a similar solution at the line item the userexits in GGB0 are not being accessed by the tcode FV60. Can someone explain where i could have gone wrong.
Note: I have activated the validations in OB28.
