Dear John
It seems highly unlikely that Adagio would cause problems in tax calculations that only show up in QIP DOS processes, even if using the same data.
There are no known issues in this regard, and although I did not test this with the old (discontinued) version of QIP, I did test it using the most current release (V6.7A 001122) of QIP using data that had not been previously used with Adagio Invoices (again, a current release 6.8A 011205). I could not duplicate this.
To rule out some obvious influences, perhaps you could suggest the following elimination processes:
1. Do a backup of the data first, then do a data integrity check on the data with Adagio - it does a more thorough check than the WSM DIC. (Since Adagio DIC works differently than WSM does, you must to do one in Invoices to check the invoices data and a separate one in Receivables to check the AR data.) If errors are found, you can click the Rebuild button to see if Adagio is able to fix them and repeat the DIC to see if it was successful.
2. Perform the same procedure using the sample data that QIP installs. Create a WSM Start List item for QIP that points to ASP\Samdata\Softrak\QI. Try the same procedure you are using for your live data to see if you can duplicate it.
3. If all looks good at this point, now - open Adagio Invoices and select this same sample data to open. If you get a prompt for the TASKS and Currency file location, enter x:\ASP for both, where 'x' represents the drive where your ACCPAC programs are installed. You may also get a message about a missing Search Header data file - this is normal.
Depending on your findings, please get back to us if you still have a problem.
Try to determine if this just occurs with one batch or a specific invoice within the archived batch.
The other thing you can try is to restore the archived batch, then re-archive it using either Adagio or QIP to see if this resolves it.
Regards,
