Hi i have some currency field in my epesi BIM. The function of this field is to update payment time to time and after certain date we will renew it and the figure need to become 0 automatically. Can the field do it or need some code to be added?
You need some custom code to do that.
You can trigger the update manually - for example when saving the record, or run cron job.
For example we integrated https://www.packagetrackr.com/ and from time to time Epesi sends requests to check the status of all packages in transit. When the package is delivered it automatically updates the status. If the package is not delivered within the expected timeframe it can be marked automatically as missing.
