Add Field BEMOT in Account assignment

Hi all

I would like to add in VA01 on item level in the register "Account assignment" the default field BEMOT (account indicator).

In VBKD the field is available but I do not find it in my sales order.

I need that field because I create a sales order with reference to a service order. In the account assignment of the sales order I enter

the sales order (and the sales order item) and I hoped that I could enter the Bemot here.

I saw that field in the item level of the account assignment at another client.

Thanks in advance for the help.

Regards

Marco
