Can I set the ItemCustomerContractReference in a sales order via ABSL

[Holzenberg]

Hi Experts,

maybe you can help me with that issue. I'm working currently on a solution, that create's new sales order items from a custom BO. The request is also to set a CustomerContractReference in those items. I understand, that the Association in the sales order has set the public write access to "no". Though I hoped to find a workaround.

I tried to set a BTDR in the CustomerContract, which returns an error

I tried to use the ItemAccountingCodingBlockDistribution. I can create that association in a sales order (because probably it is not used in sales orders?)

Does anyone have had the same problem or another idea how to change the customer-contract reference in a sales order?

Best regards

and thanks in advance
