You can change an attribute of an object and show that on a page. If you don't have an existing entity to use for that I would recommend making a non-persistable object to show on the page in question.

Thanks for comment but I am not sure that I got it.

I created an object in microflow as below, however I can’t see the object in the attributes.

I created new entity as below and now I am passing summed data to this new entity but I don’t see the value is changing. What point I am missing here?

Hello Alper Özkan,

Go to a textbox on which you want to display the aggregate value then click on textbox property then go to the event tab where you can click select, on enter from there you call your microflow.

while running your project just click on particular text then your microflow is automatically called and the value appears on the textbox. Hope this will help.

Thank You.
