How to Take Item Back in Inventory from an RMA Where Line Type is Selected Wrongly?

Hello Everyone,

There's a case where a business user wrongly selected the RMA Line Type. In the system, only referenced RMAs are created. Line Type 'Return for Credit and Return the Item' was to be selected for the concerned RMA but the business user accidentally selected 'Return for Credit' and the RMA with this line type has been processed (it is in the Closed status).
The ask is to be able to take the item back in inventory but since the line type has been selected wrongly, this is currently not happening.
I request your help and guidance in this particular case as to how can the item be taken back in inventory.
