Customer Master FI SD Integration
Picture the scenario: Due to Sarbanes-Oxly or some other reason, the FI part of the customer master is created by the Finance team. After which the SD part of the customer master is created by the Sales team. It is possible that the two teams have failed to communicate to eath other and customer master records can be sitting in your system as incomplete.
To report on these you can use the transaction OV50. This will show you the sales area created customer master records for which there are missing company code views, or visa versa. (A great little utility.)
