Transfer old item code to new item code with quantity by DTW (SAP B1 8.82)

Hi all.

I am trying to transfer all the old item codes with quantity to new item codes in SAP 8.82.

All the items are managed by batches. I have already created all the new item codes in system but I don't know how to transfer the existing quantities in the old item codes to the new item codes. Is it using the OIGN & IGN1 to receive the quantity and using OIGE & IGE1 to issue out the quantities in old item codes?

I am using SAP B1 8.82 PL12.

Kindly guide me on the above issue.

Thanks,

Leng
