ROS. organizative unit 00000000 doesn't exist, check your entry

Hi,

When the purchaser director (for example) is completing the business partner to vendor and choose any purchasing organization the message BBP_BUPA034 appear.

The error is being showed in BBP_VENDOR_CREATE_F01

We are running SRMSERVER550 SP 6

Anybody knows how I can solve this??

thanks and regards

Jorge
