Have you ever had issues with the minimum number of days to allow waived interest and fees in Dynamics AX 2012? This is a situation that I have encountered when testing waiving of interest notes with a client. Normally we would run through the standard process of generating and posting interest notes, typically using the current date. Then we would go to the Customer list page and under the Interest note adjustment section of the Collect action pane, we would either select Interest note > Waive or Transaction interest > Waive. The problem I would always encounter is that my newly posted Interest notes would never show up for me to waive.
Eventually, I figured out the cause of the problem. On the Accounts receivable parameters form, in the Collections section, there is a field (shown below) which controls how much time must pass between an interest note is posted and when it can be waived. Because my interest notes were posted with today’s date, they were too new to be waived.
You can get your interest notes to become available for waiving by either changing the above field value to 0 (temporarily for your testing purposes), or alternatively, by going to File > Tools > Session date and time and setting the date ahead (temporarily) to a future date beyond the minimum number of days specified in the field above.
Hopefully, this will help you avoid being stumped by this like I have been in the past.
