Change save process

Hi George,

You use api_application.isDMLNecessary or api_application.isDirty APIs to check whether unsaved changes exist or not in your application. The difference between these two APIs is as follows:

api_application.isDMLNecessary API returns Y when any updatable datasources existing in the application has uncommitted changes. Updatable datasource means at least one of the delete/update/insert permissions should be checked on the datasource definition. The function returns N if the modified rows don't belong to any updatable datasource.

api_application.isDirty API always returns Y if any datasource existing in your application has modified rows. It doesn't check if this datasource is updatable or not.

To sum up, depending of your need, you can use api_application.isDMLNecessary API to check only the changes made on datasources which are subject of the DML opertions or api_application.isDirty API to check all datasources.

Best Regards,
Ibrahim
