I have a item and manage by Batch for every transaction (received and issued).
there should be necessary to update Batch .after received and issued for a item.
if yes then why ?
Update Batch number window is used for correcting any mistakes or making changes to Batch numbers. It would not be required in the normal process.
During Goods Receipts you will enter the Batch number and when creating the Delivery on the Sales AR side, you will select the Batch number being sent out
