Checking whether class instance can be modified in Sage Enterprise Management

By | June 15, 2018

In Sage Enterprise Management, we have a built-in “Isreadonly” property to check whether the class instance can be modified. This built-in property returns whether the properties of an instance can be modified or not. It can be tested but not modified.


  • If MY_INSTANCE.isReadonly is 1, properties cannot be modified. Any modification attempt will raise an error with error code 143.
  • If MY_INSTANCE.isReadonly is 0, properties can be modified and accessors will be triggered. This is the default value when a class is instantiated.

Parameter Details

MY_INSTANCE: name of the name of the class instance which is to be tested. If the value is 0 then the Instance can be modified.

Kindly refer to the below snippet of code for better understanding.
