Hi, with Pega Marketing 8.x a Severe Warning is created when using a Datapage within Strategy (SetProperties). The text is the following: "Deprecation The use of data pages negatively impacts strategy performance. The best practice is to use properties and prepare the data before running the strategy. An alternative approach is using properties that reference or copy data from a data page." Now I have the following questions: 1) Why is it allowed in 7.3? 2) What is the impact if we are using DataPage within strategy? 3) In the Severe Warning following is said "An alternative approach is using properties that reference or copy data from a data page." I checked two options here:

• a) I defined a SinglePage property on Customer record which calls DataPage when demand. But when reference it in SetProperties of strategy value is empty. I can guaranteet that it working if I use Data Transform before.
• b) Try to create a SinglePage property on SR level, but this is not allowed.
