I was unable to assemble the document, using the Assembly app. The system keeps saying “Cannot process the data source”. It would be good to receive more specific information on what is wrong in the error message for troubleshooting. I used my Excel document as a source file and the sample template. Can anybody help to figure out what is wrong?
We can not give more precise description of this type of the issue because of its complication. However, we can check your files for consistency if you attach them.
