API to issue and return parts to a work order on EAM

 We are on R12.1.3. I have a requirement to be able to issue (and return) stock items from stores to work orders. 

For example, given work order "WO1", (wip_entity_id = 12345), I want to issue 1 of part number "PART1" (inventory_item_id 2345) from locator "A-01-01" (inventory_location_id 3456) from subinventory "PARTS ROOM".

 

I may also need to return it back to inventory if it is not actually used.

 

I have tried using a WIP COMPONENT ISSUE using MTL_TRANSACTIONS_INTERFACE, but that doesn't work for EAM.

 

I have found EAM_MATERIALISSUE_PVT.Fork_Logic and that seems to work for issuing parts, but not for returning them, and I am not sure if this is the right API to use in this case.
