How to handle scrap occured during processing

Hi all,

I am facing problem with handling the scrap occured during processing. The case here is i want to scrap the material eg ABC, and want to sell the same material with different material no., unit of measurement.

The present process is as below,

The scrap occured during process is been collected & is scraped using Tcode MB1A, with movement type 551 or is added in the scrap feild during confirmation CO15. As per my knowledge this scrap is accounted against the costcenter and then it is out of the system. Now in order to sell the scrap the same scrap with new material no.is loaded back in the system using movement type 501. The same is been sold.

Requirement is that i want the link between the scrap & the scrap been sold.

Want to avoid movement 551 & 501, which is in practice rt now.

The same process is followed from past 5 months. So we cant go with the option of Byproduct / phantom assembly as we need to change all master data.

Can some one suggest me how to go about it, its urgent!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Regards,

Arun
