Hi Kiran,
Keeping By Product in BOM as -qty will give 531 as receipts of By-Product while production order confirmation, perhaps this is ok. And same I can issue 261 in Order also.
But bottleneck is how to do the settlement of Order.
The continuous 531 and 261 of By product looks order unsettled at month end. Suppose, we are left 10 kg of each by product in your stock and order is fully confirmed. And you need to make a fresh order.
Where I will put this 10kg of each By product?
Is this doable if I do 532 movt type in the fully confirmed Order, and in next Fresh Order same qty of By product I should do 531???
Best regards
Shailesh
