Question: How do I get rid of duplicate record numbers? Answer: In the following example, we will assume that record number 150 is duplicated. While completing these steps, replace 150 with the duplicate record number you found in your project. To delete a duplicate record, press F5 to open the Individual Edit window. Press F10 and enter the record number (150). Press Enter then OK. Change the record number to a record number not being used (i.e., change record # 150 to 10150). Press F9 to save. Press F10, enter the record number for the duplicate (150). Press Enter then OK. Press Shift + F9 to delete this record. Once deleted, press F10, enter the changed record number (10150), press Enter then OK. Change record number 10150 back to the original number (150). Press F9 to save.
