This error has been reported before, however, we have not been able to determine what is the actual cause.

That file does not exist in the sample data for IC6.5A as it comes from AI. We cannot replicate this error here, using DataCare on IC6.5A samdata, even though the file does not exist...nor does the WSM DIC give an error - this could indicate that something in your data files are triggering this message...but since both the DIC and DC are reporting it, it would not be a DataCare issue in itself.

It could have something to do with either the version of WSM that you are using, or the fact that you have POV6.1, yet have the IC65A/PO65A combination installed.

You could experiment by renaming your old PO data files, and then check it to see if the message goes away. I am using the same release of DataCare that you are, with WSM7.0 installed and do not get that message.

You can contact AI to see what that file actually does, we suspect it is an index to the item PO file.
