When creating an Alert in Microsoft Dynamics AX ERP software, the field where you initially create the Alert affects your options when defining the Alert. For example, if you start defining the Alert on a date field, the options displayed are related to dates: “has been postponed until at the earliest,” “is set to an earlier date,” and “is due.” For numeric fields, available options include: “has decreased,” “has increased above,” and “has decreased below.” Alphanumeric fields options are “record has been created,” “record has been deleted,” “has changed,” and “is set to.”
