I'm working in a Pega 7.2 application and I want to properly create a Data Transform and trigger it from a dropdown, this dropdown has 6 items. When choosing item 1 or 3, the Data Transform should limit a text property to have a max char length of 10 (this property now has a max length of 255). I created the other elements in UI, but now I'm stucked. Any advice will be appreciated.
Do you have knowledge on Validation Rules?
If yes then I can give a simple idea.
Create a action on change of the text property.
Apply Refresh Section and call one Activity.
In the Activity call one Obj-Validate rule. In the Security tab of the activity choose Validate from the activity type dropdown.
In the Obj-Validate rule check the condition if Drop down property value is 1 Or 3 and text property value length is greater than 10. Then, set message on the property as the length should be 10 only.
Note :- Add Post action on change of the drop drown before applying above logic.
Another logic -
If this Section is getting called from a Flowaction rule then open the Flowaction, go to Validate tab and call the Obj-Validate rule which you are going to create in first logic.
