Differentiate reverse material from Issued material in MB5B/MB51.

Dear Gurus,

I have one problem that,when my client issue the material to production byMB1A- (mvnt.261) and when it take reverse the same manually i.e. without any reference.Then in MB5B & MB51report,the reverse material adds in issued material due to which there is qty. difference in MB5B & MB51.

I wish to differentiate this reverse material in overall stock report OR this material should not be add in issued material.

Please give the solution.

Pankaj.
