As stated above,
- Maintain Cost Center CTR as default receiver in Settlement profile
- Maintain Cost Center in Technical Object
This should satisfy this requirement. Because, when you do mass release in IW38, system will not give that message to select with default receiver or no default receiver.
This is applicable even for auto release through maintenance plan.
Just a simple check, create orders with same order type as well as some other order type manually in test server & do the mass release through IW38. Then check for both order types.
