Hi @SahuSa1, I'm sure you have an arrangement for all app versions that identifies from which app version traffic is coming from i.e. a field the captures app version
In my opinion data-stream (exclusive to AEP) is the place where, while mapping you can use data-prep to conditionally decide what to populate and send to AEP.
E.g : iif (appVesrion="XXX", attributeName, "")
attributeName - If version matches you wanna send the value else keep it blank.
Above was specific to one attribute. If requires to be done for complete record/payload nothing exists to my knowledge and you will have to do it across all the fields.
