Can you open your data mapper and template in the Designer tool, using the data file in question and try to generate a proof print? It’s possible you may need to convert the datamapper and template to the latest version first. Then if proof print runs without error, resend the data mapper and template to workflow and try running again.
Failing that, please open a Technical Support ticket and send your data mapper, sample data file and workflow for further investigation.
I built the mapper and template in 1.7.1.44448, so no conversion necessary. Proof Print generated the entire tables worth of output without issue.
I have to be honest. I spent a bit of time searching for how to use an Access .mdb as data in a PPC workflow and found little. But, I tend to be more of a try it and when it doesnt work, figure it out instead of reading first kind of guy.
I tried every thing I could think of to get this working. I was just about to open the ticket and I thought, OK try one more thing… I added a Load External File pulling in the .mdb file as the active data file just before the Execute Data Mapping.
And it worked. no error…
I am a little surprised (and confused) that having the .mdb as the active data file is how it works.
