Wiping out Old Batch Characteristics in MSC2N

Hi,

I have a requirement where I have to do a Material-To-Material Transfer (VLMOVE) and update the Batch Characteristics in a Custom Inbound Posting Program. Now, I am able to update the batch Characteristics for the new Material with the Characteristic Values received in the Inbound IDoc.

However, I am unable to wipe out (Clear) all the Old Batch Characteristics for the Old material. Can somebody give me an idea as to how exactly do we go about clearing all the Batch Characteristics for a Material - Batch Number in MSC2N Transaction?

Thanks and Regards,

Venkat.
