The requirement is :
While creating a PR for a material with only short text(no material master record), we have to enter the material group also.
If the material group is not supplied by the vendor then the system should give an error and not allow the user to progress with PR creation.
What we currently do is maintain the material group supplied by the vendor in the vendor master record's SEARCH TERM field of address data. I know this is just for information sake.
Kindly suggest a way to fulfill this requirement.
