By product is not reversed on cancelling the GI in PI sheet

Hi All,

I have a scenario where we have a logic in pi sheet that on cancellation or partial reversal of GI of component material, reversal of byproduct is done. In one particular case, even after partial reversal of GI of component material, there is no reversal of by product. Process message is sent successfully with commit work.

Any idea about what might be the issue?

Thanks
