I am needing to run an Open Balance Export job that contains specific headers that are located on different tables. The primary table I'm using is the `AR_OpenInvoice`, to which I am attempting to link to the `AR_InvoiceHistoryHeader` table. The problem I am having is that, while I can select the columns from the linked table in the data tab of the export job, these headers simply do not export.

Here is my link from OpenInvoice to InvoiceHistoryHeader, using "InvoiceNo" as the primary key. This key is located in both tables.

Here is a simplified example of a report I am trying to run, just using two headers - 1 from each table:

which gives me this output:

As observed above, Column 2 is non-existent, which is the issue I am needing to figure out.

Any ideas where I'm going wrong here?
