Reproducing the Issue
When posting a partial incoming payment in "Post Incoming Payments" app, the system automatically picks the document date as the baseline date.
You would expect that the system will consider the baseline date of the original document.
A partial payment is a payment that is posted to an account without any open items being cleared.
When posting the partial payment, the system picks the journal entry number of the original open item as "Invoice Reference" in the line item of the partial payment.
The original open item and the partial payment item remain open.
The payment terms and the baseline date are not copied from the original invoice document to the partial payment document.
This is a standard behavior.
Solution 1: Use "Residual Amount" instead of Partial payments.
For residual payment, the payment terms and the baseline date will be copied from the original invoice document.
The filed "Residual Amount" can be found by clicking the "Full Screen" button.
Solution 2: After posting the partial payment, you can also manually change the baseline date.
