Hi Shyam
Ludwig Reinhard posted a suggested answer back in 2016:
"This is a call Center Parameter. The Parameter term is MCROverUnderPaymentPrompt.
Prompts the user to not allow out of balance sales orders to be processed. Otherwise payments will always be processed. (This field applies only to the following version(s): Microsoft Dynamics AX 2012 R3)
Please see: msdn.microsoft.com/.../salesparameters.aspx
Does this answer your question or do you need any other information?
Ludwig"
I tested the functionality using a regular customer payment journal and don't see any impact in that relation. I was hoping you that I get some kind of error mesage related to wether I select the parameter or not, but it did not have any influence. I think that Ludwig as always has the correct answer even it is three years old.
Kind regards
Sten
