Mark,
If you have an entity defined like this:
and want to set the value of the Combined attribute in a microflow Change Object Activity, you would do it this way:
However, I am not sure why you are using Xpath - maybe I don't understand what you are trying to accomplish.
Mike
below + acceptable + developed + exemplary
This will work as long as each of those 4 attributes is numeric.
For the user-experience it is nice to update the sum field on every change of the underlying attributes.
Don't know why you would want to solve it in the xpath. It totally works fine, even with an xpath data source in the way Mark explained.
Since it is 7.13, this is a perfect usecase for a nanoflow. See https://question89511.mxapps.io/index.html?profile=Responsive
Click the any line of the datagrid. The dataview below has a this nanoflow connected to the onchange of the below and the Accepted field.
Advantage of the nanoflow over the microflow in this case is the nanoflow not triggering a roundtrip and thus being lightning fast.
