Save values in activity with savable data pages

Hi i’ve this activity where i save my test values into params:

Then i call a data transform “MapLogMail”,where i do this:

Finally i have my savable data page:

But when i run the acrivity the record isnt’ written in the data type. Anyone knows why ?

@FabioP16585881 you can"t save data directly,inorder to save the data you can use savedatapage method in activity or you can use data save option in post processing flow action

@Motukatla Like this? but it didn’t work

@FabioP16585881 instead of using activity use source of datapage is datatransform and do the modification what ever you want in DT and save the data page in flow action.

@FabioP16585881 you have used activity no need to use activity.if you use activity then sourse of savable data page use activity and use property set method to map data page parameters with your desire values and call the savable data page in flow action.you can perform save option any one data page source either Data Transform or Activity no need of both ok.
