Payments

I'm glad you added the column successfully. To ensure we're on the same page, did you enter the Discount Due Date information when creating a bill or on the vendor profile? Allow me to provide details on why this is happening and help you decide what you can do, Sunny20.

But before we begin, can provide a screenshot of the Discount Due Date details from your entries? This will allow us to thoroughly assess the issue.

If you're able to enter the information when creating the bill, that data is pulled from the vendor payment terms and should automatically populate the appropriate columns in the report. In terms of reporting, the "source" refers to where the data originates, which, in this case, is the information you entered in the bill.

On the other hand, if you input the information on the vendor profile, this will be generated on the Vendor Contact List report. I've added a screenshot for your visual reference: 
 

Once done, you can generate both the Vendor Contact List and AP Aging Detail report, and then export both reports so you consolidate them into one.

To give you more information on the available reports that you have access to, check out this article for reference: Understand Reports.

Feel free to reply below if you have any other concerns when managing payment terms on the report. I'm always right here to help you. Have a nice day!
