Unable to link table

[BasSchouten]

We've developed a product in Delphi 4 which makes extensive use of Crystal reports, using data from the Xbase (dBaseIV) datafiles from the product.

Every now and then when i'v changed something in the reports, or have copied the reports from the develop-environment to a production environment i'm getting an error in Crystal Report when previewing the report:

Unable to link table '<table-name>'

Checking the linked database, everything seems allright. refreshing the links to the tables by removing them en re-defining doesn't work.

ANybody any idea what's going wrong here?

The field data types must be the same. Are they?

I'v noticed this problem occurs when I copy the .RPT file to a diferent computer, where the data and report files are in a different directory.

Does Crystal use the absolute path of the linked database-files, or does it use paths to the report directory?

If you are linking directly to a dataabase I would say yes. Changing to ODBC connections should resolve this problem.
