Merge multiple parameters

The Foundry Reports application has been sunsetted, and legacy reports are now available as view-only. Refer to the Reports sunset announcement for further details.

Overview

Reports lets you merge many parameters into one. This is useful for reducing the number of parameters in a report, particularly in the following cases:

If two parameters are conceptually identical. For example, if you added two Contour widgets from different analyses, they may each have pulled a separate Year parameter into the report. Merging the two Year parameters together allows report viewers to control both Contour widgets with one parameter value.
To display a parameter value in a text block. In some cases, you may want to display the current parameter value in a block of text. Merging a parameter created within a text block (as described in Add a parameter within text) into a parameter imported from another application (as described in Add a parameter from another Foundry application) will accomplish this. This workflow is also discussed in Edit text in a report.)

Concretely, merging Parameter A into Parameter B will:

Hide Parameter A from the parameters bar, and
Cause all widgets that were affected by Parameter A to be affected by Parameter B instead.

Merge parameters

To merge one parameter (“Parameter A”) into another (“Parameter B”):

(If needed) Switch to Editing mode.
Click and hold the drag handle for Parameter A.
Drag Parameter A onto Parameter B, still holding the mouse button, until you see a “Merge” icon and label.
Release the mouse button.
Click Merge in the confirmation dialog.

Merged parameters will show a small “merged” label beneath the parameter's title.

You can merge as many parameters as you want into a single parameter.

Unmerge parameters

Merging is a reversible operation. Unmerging a parameter will:

Display all linked parameters in the parameters bar again, and
Cause all widgets that were originally affected by the linked parameters to be controlled by those parameters again (instead of the “master” merged parameter).

Unmerging a merged parameter will cause all of its linked parameters to be unmerged, not just the most recently linked parameter.

To unmerge a parameter:

(If needed) Switch to Editing mode.
Click the gear icon next to the merged parameter in the parameters bar.
Click Unmerge in the Parameter Settings menu.
Click Unmerge in the confirmation dialog.
