3330073 - ASSIGN on Empty Generic Box

You create several extension fields for purchase proposal and also add them to service ManagePurchaseProposalIn. However, error ""ASSIGN on empty generic box"" occurs when calling the API.

SAP Business ByDesign

Inbound Service Manage Purchase Proposals has clearly stated that this interface Operation Create purchase proposals does not support extensibility.

You need to remove all the extensions from the operation of the service.

As a workaround, you can add extensions under Root Node.
