Audit not recording specific users transactions

[cognosun]

We have an Audit package , which is successfully recording information about all the other packages which we are accessing in our environment.

But there is one package , whose transactions Audit is ignoring.

If a person with admin rights access that package...Audit is recording his data...but if the users ( authors) of that package access it,  audit is not recording the data.

Any suggestions please...would there be any issue with user groups of that package ?
