It is possible to change user amount field to a specific value. However, it is not possible to perform any mathematical operation based on some other specific amount field.
E.g. if Account is “ABC” and Reference is “OD Interest” and Data is outstanding for more than 5 days then there should be workflow to populate 2% of Amount into Interest Amount column. This kind of workflow setup is not possible in Task Automation.
It will be better if we can include mathematical operations considering existing field value in IntelliMatch.This will help in setup of different kind of workflow in IntelliMatch which is currently custom process at present.
