We unable to modify the operator / perimeter to modify deep/ link / standard . It was working fine & now couldnt find the root cause of the issue . Please suggest us if we need to modify anything .
If you have enough access and still not able to update , then try Translate and Compile of environment and then do changes .
Once I had similar issue and I tried this solution .
It is not recommended to update a standard _Operator such as 'Standard for comparison'
It is recommended instead to create a custom _Operator that inherits from the standard _Operator and to configure this custom _operator.
@jhorber We have duplicated an existing perimeter and tried to modify , But no luck still .
Metamodel changes is enabled as "expert" and "authorised" to all .Any option in the setting we need to enable for this ?
Try to use explorer tool or command line to update configuration
Ultimately, configuration is saved on a link between a MetaAssociation and an _Operator
