Organization Unit does not exist error

Hello All,

We have a error "Organization Unit does not exist" while performing the transaction Workload Distribution.

I have gone through some threads and got some information saying to move the purchaser under a Purchasing group.

Logically we cannot do this always we cannot assign the Purchaser directly to Purchasing group.

So kindly do let me know your suggestions to come over this Error.

Regards,

Kiran.
