Custom Source to modify the SLA in Cost Management

Hi

I have created a custom source in Cost Management to generate a value in one of the segment in the account code combination during accounting.

First I tried with the parameter 'TRANSACTION_ID' and later i tried with the 'INVENTORY_ITEM_ID' (Since i need to generate this segment value based on the one of the item category that we designed for this purpose).

We have successfully assigned the source to a custom ADR and that to AAD. Also we successfully validated the AAD.

We have tested by assigning it to Miscellaneous event class and tested it with creating a miscellaneous receipt. But the segment value is not populating as expected.
