i am trying to include search help for MM03 trasaction based on MATKL(material group) WGBEZ (description) in the form of alv tree display.
Fuctionality i want to achive is :
1. after pressing F4 on MM03, it prompts to select material group screen, on pressing F4 on material group, now i am able to get the ALV tree display of all the materials and description based on the selection screen criterion.
2. now, after selecting one material group from ALV screen, i am able to map the corresponding value on the material group on the previous(intermediate) screen, but after pressing enter on this screen, i need to get the corresponding material to be mapped on the MM03 transaction, which i am unable to get.
when i press enter, it is again going to ALV tree display only and values arent getting refreshed.
Please help me in solving this.
