Workflow for MM11

Hi all.

Hopefully I'm in the right forum to look for some alternative/ answer for my problem.

I have a workflow requirement for scheduling maintenance of material master. When user executing transaction MM11, I want to copy the material type that filled by user into certain variable then I need to do come checking. I could not find any appropriate business object type to handle this. The existing business object type BUS1001 and BUS1001006 always check the material number to MARA table. Since this is a scheduling not direct creation the data is not stored in the MARA yet.

Any body has suggestion how to handle this?

Thanks,

Maorriyan
