How to pass the name of a property as a parameter to an activity and update that property in the activity
I want to be able to update properties in a case via an activity (or data transform). But the property being updated could be different each time, so I want this activity to be reuseable.
Is there a way to pass the name of the property to be updated AS A PARAMETER and have this property updated with a value (also passed as a parameter) using either an activity or data transform?

@RobertH9685 Hi, if the list of properties to update is too long for the above approach to make sense - you can use the setPropertyValue function from RuleManagement library.

@RobertH9685 Send the Property name as a param to a DataTransfrom and use when conditions to determine and set corresponding property value under when condition. you can write multiple when conditions for different params values.

@walol First of all, thank you for your response and the timely manner. I have been able to make this work with some syntax changes.
This function will update the property (param.Pname) with a new value (param.Pvalue)
@RuleManagement.setPropertyValue(myStepPage,param.Pname,param.Pvalue)
This is done in an activity rather than a data transform.
The activity takes the following parameters; InsKey - .pzInsKey
Pname - Property name - must be the full path of the property (eg - ".Page1.Page2.PropertyToUpdate"
Pvalue - Value for the property being updated
WorkPage - Always passed as "pyWorkPage"
Key Activity steps as follows;
1. Obj-Open-By-Handle (WorkPage)
2. Property-Set (WorkPage)
@RuleManagement.setPropertyValue(myStepPage,param.Pname,param.Pvalue)
3. Obj-Save (WorkPage)
This works for most property types - (Text, Int, Decimal, boolean) - Date will need to be converted if your parameter is a text format.
