Hello! Does anyone know the possible cause for error:

You cannot void this transaction because it is linked to by one or more transactions such as payments. You must delete or void those transactions first

when I try to copy the same transaction in SB, I was able to void it with Bills applied and Currency Revaluation linked. I'm not sure what else to check. TIA!

do search on applied and applying transactions

There are bills applied to and currency revaluation applying to, what confuses me is that I was able to VOID it in SB even with linked transactions.

Sandbox behaviour is an unexpected one, production is the right one
