You get duplicated entries in the audit file.

Symptom: When you record a single "change" operation, the audit file records a "read", a "change", a "read" and a "change" again (double reading and changing).

The problem is that your "Store Record" field in the Audit File and/or the global memory is not long enough to store the whole record. You should increase its size in the global data area, and it should have the same size in the audit file, the auditbck file and the auditnew file. Check the Definitions Tab chapter, and try the TXD Analyzer companion program to verify the maximum length of your records.
