Hello Ray,
There are other options depending on what functionality you need to enable.
If you're happy to return goods, so that the Production Order is correctly costed for the raw material return, the Documented Goods Movements report is updated (if you activated it), but that the "Withdrawal Quantity" is NOT updated on the Components tab, you could use MIGO - Goods Receipt - Other, where you enter in all the details of the stock you're returning, and on the last tab you refer to the Process Order.
This can work well for some - but one new issue is also that it's uncontrolled in that any material (even one not on the Components tab) could be received back from your Production Order.
This may or not be useful for you, but it's certainly the most direct method if the downside isn't an issue for you.
