Run an R68 process (Run 1) with tax claim number e.g. TC1 to pick-up one of the test payments above - do not submit to HMRC yet 2. Edit the same R68 process and change the tax claim number e.g. TC2 and edit the selection to capture the 2nd test payment 3. Run the updated R68 (Run 2) - do not submit to HMRC yet 4. Confirm the records captured are correct using the R68 report 5. Submit Run 1 to HMRC - notice it has the Run 2 tax claim number embedded in the xml submission file
