Hi @Pavan Kumar S 

Please check with the below functionality:

@(Pega-RULES:Utilities).getLocalizedText("FieldValueName\t"+Param.Name,"pyCaption",tools)

@Pavan Kumar S To call a Field Value in a Data Transform, you can use the @Utilities.getLocalizedTextForString() function provided by Pega. This function retrieves the localized value of the Field Value for the specified property or key. To use it, define a parameterized key or property reference in your Data Transform and call the function, passing the key of the Field Value as an argument. For example, set a target property to @Utilities.getLocalizedTextForString("FieldValueKey"), where "FieldValueKey" is the Field Value's key. If your Field Value is context-sensitive, ensure the correct locale is set in your user session to display the localized text appropriately
