ISH billing - How to default to a single cost center for a revenue account

[Former Member]

When processing invoices from ISH module (with transaction NA30N) our aim is to have for certain revenue cost elements the cost center to be derived NOT from the settings in transaction NCOP 'revenue account assignment' but INSTEAD to overrule for these particular cost elements with the cost center as it is defined with the transaction OKB9 (in customizing CO module ).

To achieve this I have filled the table OKB9 for these particular cost elements with the default cost center taht we want but it turns after executing the invoicing in ISH with transaction NA30N it turns out that this cost center is not posted to. It seems that the interface between ISH and CO does ignore the OKB9 settings and instead only uses the settings from transaction NCOP in the ISH module (in other words; the cost center that is derived based on the ISH organisational units ).

Does anyone know how to overrule the cost centers settings in transaction NCOP 'revenue account assignment' with a default cost center setting from OKB9 table ?

Hi,

in the respective IMG activity documentation Assign Cost Centers to Organizational Units you find the following:

Customer-Specific Cost Center Determination

The SAP enhancement NHCO0001 provides a function module exit by means of which you can implement an alternative cost center determination without having modify the standard source code. For more information about this option, refer to the documentation for the enhancement and for the function module exit.

Use TA SMOD/CMOD to display the details and implement the desired functionality.
