"Start" production order effect on component item transactions

Dear all:

Hope you are doing very well.

When I change the production order quantity at the start step to a lower quantity than the original production quantity , the system split the additional quantity in a separate line in the item transaction , with the same lot ID and the same voucher and true cost , but I want to ask if this is a standard behavior in the system and if the two transactions with the same lot ID and same voucher considered as one transaction in system calculations?

Regards

You are not changing the quantity at the start step, you are simply starting part of the overall order, leaving the remainder to be started a different time.
