Hi Community. 

We work in the Aviation industry, and often we use External Service Orders, (ESO) to send parts from stock to a repair station to get them repaired and then returned for us to fit back onto aitcraft. 

Often we send parts out that may come back with a modification carried out that changes their part number slightly, and therefore changes the fit/form/function of the part. For example, a part 101-11 may be sent out, then returned as a 101-15. It will often keep it serial number if serial tracked. 

Currently we use the Alternate Parts functionality to register 101-15 as an alternate for a 101-11, then we use the “Change Receipt Conditions” to change this to receipt in the correct part from the supplier,  however due to the modification, this is not truly accurate, as the modified part (101-15) may not have the same characteristics, or uses as the original part (101-11). 

The only alternative we have considered is receipting in the original part, 101-11, then performing a part no, serial rename, and changing the part upon receipt, however we then have the issue that the receipted part in the system was technically not correct, as we did not receipt a 101-11, we received a 101-15, and the paperwork that comes with the part reflects this. 

Has anyone seen this or have any ideas on what we might be able to do, we understand that this is very common in the A&D space, therefore IFS must have a solution somehow. 

Many thanks for your assistance.
