When the user would like to delete some of the generated interest, the system prompts a message "Sorry. Invoice already charged late interest!" and the interest unable to be deleted.
This is a control feature to avoid any deletion of interest being generated.
System found a conflict between the new and last charged interest date. This happened when the user revises the interest date after he has generated interest, where the newest revised interest date is earlier than the last generated interest date.
To resolve this issue, follow option 1 and follow option 2 if the solution does not work:
Option 1
Delete the last generated interest.
And re-generate the interest by following the date sequence.
Change the interest date to the last generated interest date in the module of Revise Interest Date.
Thereafter, delete the existing interest.
Option 2
Reverse the knock off the related invoice from the late interest.
Reverse Credit Note (If you have waived the late interest).
Delete the late interest.
Note:
To update the interest date, make sure the revision is done before interest is generated in the system.
If the update cannot be applied afterward, the recommended workaround is to issue a Credit Note to reverse the late interest charges.
