Run Sales order wise MRP - AFS material

Dear Experts,

                   Here my client asking to run the MRP for sales order wise. recently we did the AFS implementation for one of our client. there is an common T-code for MRP run, for AFS material is /AFS/MD02 . they are using material based BOM ( Bill of material). so there might be common material for different sales order i.e if am using material XXXX for Sales order 500 mean , same material will present in  Sales order 510 too. current system

( T-code /AFS/MD02) will run MRP of material XXXX Both 500,510 sales order but my requirement is i need to restrict to single sales order.

any one guide me to resolve my requirements.

Thanks in advance...

Regards,
