customer - company code extension

Hi,

Below is the scenario for which we are looking for a solution.

When a customer is created in the CRM system, the details flow down to ECC using BDOCS/IDOCS. CRM does not have company code details. But we need these in ECC. So when the BDOC is being processed, we are looking for a BAdi or any exit thru which we would be able to add data to KNB1 structure.

Any pointer to this would be helpful.

P.S: the BAdi customer_add_data (method - preset_values_ccode), does not get called when I test using XD01-> save.

Thanks,
