Integration Manager Syntax Error (Missing Operator) In Query Expression

Microsoft Dynamics GPA client recently logged a problem with our Service Desk to report that an Integration Manager integration wasn’t working; when trying to run the integration they received an error message on every line of the integration:

Integration Results
    100 documents were read from the source query.
    11 documents were attempted:
        0 integrated without warnings.
        0 integrated with warnings.
        11 failed to integrate.

After doing some debugging of the integration, we identified the problem as being caused by the source column headers; all of which had multiple # at the end.

For example, as you can see in the above error message, DATE was displaying as DATE#######.

We went through the source removing all of the # symbols and were then able to run the integration without receiving more errors.
