In the April 2026 release (26.04), Calculation Control 1.0 is the default. You can preview and start using the new Calculation Control 2.0 screens by entering an EPCM_CALCCONTROL_UI substitution variable to specify 2.0.

1. From the Home page, select Tools, and then Variables.

2. On the Variables tab, click Substitution Variables, and then click the plus sign to define a new variable.

Starting in release 26.07, the original Calculation Control 1.0 screens will no longer be available.
