Migration Job Error - Method List

Interesting. It seems like a limitation of the FNDMIG. You won’t be able to use this method. Maybe there is another procedure, usually an API triggered by the SVC..

I agree with ​@FlorianTauber: this is almost certainly an IFS Data Migration/FNDMIG metadata issue. The error is very likely caused by an IFS Migration Job technical limitation. In this case the error message is pretty clear in what’s going on: the column has a maximum length of 30 characters, but one of the generated attribute names is 34 characters long. In other words, when you add:

Move_Inventory_Part_SVC.Do_Update_Inventory_Part_In_Stock_Delivery

IFS tries to generate method attributes/references, but at least one parameter/attribute name from that service method is longer than the migration job metadata table allows

Here are some solutions, although I have to say I have not tested them myself, only ideas for you to think about (in order of how fast they are to implement)

Option 1 — Use a shorter/lower-level API method if available

Look for an older PL/SQL API method behind the projection/service call, something like an Inventory_Part_In_Stock_API method, rather than the long Move_Inventory_Part_SVC service operation.

Option 2 — Wrap the call in a custom PL/SQL procedure

Create a small custom procedure with short parameter names, for example:

Custom_Move_Inv_API.Move_Part(
   contract_,
   part_no_,
   from_loc_,
   to_loc_,
   qty_
);

Inside that wrapper, call the correct IFS API/service logic.

Then add your wrapper procedure to the Migration Job Method List instead of the long service method.

This avoids the 30-character migration metadata limitation.

Option 3 — Use a custom projection/API or integration instead of Migration Job

For inventory movement, especially if it creates inventory transactions, I would be cautious with Migration Jobs. A custom REST call or integration using the supported IFS business operation may be safer and easier to control.

Hope this helps!
