Batch Classification copy from component material to Header Material

Hi Gurus,

Requirement to do copy of batch classification from component batch to header batch in process order during GR. I don't want to use Batch derivation option to avoid records maintenance.

What are these enhancements or user exit which i can use for this requirement (Batch Classification copy, Batch header data copy, AT GR of process order)?

Regards,

Shiv Kumar
