Hi there,
It’s probably have the capability to show the cube value with snippet by tm1-ui-dbr or anything that as one of the parameter in th process widget?
Yes this is definitely possible to pull out a value and display it with the html-before or html-after section. However, I’m not sure that the value would respond to a change in the parameter subnm selection (I would actually guess that it wouldn’t).
As an alternate design you could split to separate widgets all embedded in a dashboard.
a “navigation” widget to make the from/to selections (Or even just a normal grid widget with hyperlink to chnge filters enabled only showing 1st column)
some single cell DBR widgets to show the current values being copied/replaced
A embedded TI widget to run the allocation that just takes the setting service value with entry disabled from the navigation widget
