Hi Team, I have integer type customer Id text field, if feed the customer id as negative number then i have to fire custom message from the microflow. but in microflow , I am getting always empty value instead of negative number. please help me, how to process negative number in Micorflow ?
From your problem description, I don’t exactly understand your setup. For that reason I do also not understand why your value is empty in your microflow.
Nevertheless: a good option is to go to your domain, select the entity and set a validation-rule for that attribute. Here you also can set the message shown in case of validation-error.
