While creating a new order management transaction type & defining sequence number, we were hit by the error “ORA-20001: APP-FND-01728: An assignment does not exist for these parameters”
Oracle has couple of documents addressing this error
- ORA-20001: APP-FND-01728: An assignment does not exist for these parameters (Doc ID 2275689.1)
- Order Import Does Not Create Orders, errors errors ORA-20001: APP-FND-01702 (Doc ID 1298436.1)
In our case, both these documents were not of much help. After long hours, we rectified this error to wrong selection of LEDGER while the document sequence was assigned to the newly created transaction type.
So, if the above documents are not of much help for you as well, do check the LEDGER assignment & correct it.
