Create link between Handling Unit and Inbound Delivery through API part2

[tiborolle]

Hi how to link through api inbound Delivery number with Handling Unit?
Handling Unit was created through API with custom numbering. Wanted to add refrenceDocumentNumber (Inbound Delivery) The HU was created but the added Inbound Delivery number not.

Tried to create an Handling Unit item with the same refrenceDocumentNumber and refrenceDocumentNumberItem but API error says the parent Handling Unit has no refrenceDocumentNumber.

What is the process link Inbound Delivery and Handling Unit through API?

Unfortunately it is not possible to create plan-HUs for an inbound delivery using the OData APIs.

It is unbelievable to me that such a robust ERP system cannot be mapped from an external system with an API, a warehouse process called "Record HU by Delivery". I can't believe it."
