Purchase requisition and planned order as MRP result.

Dear gurus,

i would like to know if there is a way to create both purchase requisition and planned order in MD04 result of MRP run.

For example i would like to optain purchase requistions for the requirements into the month and planned orders from month onwards.

I thinked that scheduling margin key could be work for me but i don't know how.

Thanks a lot

Daniele
