I also have a similar issue. We receive checks that need to be applied across many invoices where the invoices may or may not be paid in full. If I have just one invoice, I can now apply a partial amount to the specified invoice (based on another blog that I found, I had to "Double click on Destination Mapping then click on the folder Cash Apply. There will be two tabs on the right hand side. Click on the tab called Options, set the Rule to "Use Source Recordset" then choose the field that you want to match under the Source column".)
I use the default for distributions, so that is not an issue.
My issue is that I have not discovered how to apply one check to many invoices. My input "source" maps to Customer ID, Amount, Check/Card Number, Apply-To Document Number, and Apply-To Amount..
I would appreciate some assistance. Too bad Bruce did not fully document how he assisted Steve. I am at a loss as to what to try next.
Thank you.
