field exit and Authorization grp

Hi All,

I have the following requirement...

I Created a field exit for the data element (MATKL-for example)..Is there any chance that we could use that AG as indicator to evaluate in the field exit???

That is...

If the material group(MATKL) has the AG(Authorization group) populated with a value (ZRES – for example) ,then that particular Material group is restricted and should not be used in the creation/modification of documents.

Is there any possiblilty of achieving the above requirement..??

Please suggest a solution.

Regards

Shiva
