Issue with batch processing using OData service API_SALES_ORDER_SRV

Dear experts,

I am currently facing a problem of using the batch processing of the OData service API_SALES_ORDER_SRV to patch multiple sale order item texts.

I am using following batch request to patch specific sales order item texts in the S/4 system:

Unfortunately I am receiving the following error message:

It seems that my own user, which is used for sending the batch request, is blocking further processing steps.

I also checked in the system that I do not block the order.

Many thanks for your help!

Best Regards,

Timo
