TN cache problem

Hi,

We have multiple instances of TN for dev, test and prod which we have now decided to keep in sync by using only export/import to update test/prod and manually update dev.
But before this was decided, we had manually updated the TN in test. So, after an import was done into test with the dev data, we had duplicate document type attributes in the test server. The duplicate document type attributes were deleted so that only the ones imported from dev stayed. After this was done the tables “bizdocattributedef” and “BIZDOCTYPEATTRIBUTE” did not have the id values for the attributes created in test. But when an export was done on the test server, the exported file showed the id values for the attributes created in test.

Does anyone know if any table/cache needs to be cleared so that this does not happen. Please let me know if you need more details to understand this problem.
