3366826 - Get error message "The component to be assigned has not been completely specified" when trying to create routing via API_PRODUCTION_ROUTING

You want to create a routing via API_PRODUCTION_ROUTING.
You use the deep payload (to_OpCompAlloc) to make the operation component allocation at the creation.
However, you get the error message "The component to be assigned has not been completely specified" and "No suitable object found".

SAP S/4HANA Cloud, public edition

Since you use the deep payload, you may maintain the "ValidityStartDate" property for the routing header. If the "ValidityStartDate" is out of the BOM item valid period, then the system cannot find an available component and will raise the error.
For the example of a deep payload, please check this Help Page.

Actually, the "ValidityStartDate" is not mandatory for the routing header. If you need to maintain it, please make sure it falls into the valid period of the BOM item which you want to allocate to the operation.
