You can have an interactive flow or execute visual actions by creating rules with formulas in application screens.
Usually hide, show, freeze, open to edit or change color, location, size actions are done for the determined objects. You can apply all these controls in all application scenarios easily and flexibly.
Depending on the situation in the application scenario, you can connect objects or actions to department, user mail, location, title, marital status or user choice in multiple-choice actions.You can apply all these controls in all application scenarios easily and flexibly.
In this article, we will be talking about managing the conditions in the screen centrally and formula evaluation duration. And most importantly, we will talk about the importance of executing an action after the formula evaluation duration is done.
What is Formula Evaluation?
Formula evaluation is the test done during the result that is created by the written formula. Depending on the performance of the formula, a certain duration is needed.
Why Does Formula Evaluation Takes Too Long?
Depending on the performance of the formula, duration will be longer or shorter. As the conditions in the screen get more complex; main reasons like using nested formulas, waiting for the control of different objects related to each other to be complete, and executing an action depending on the respond from the data source can make the duration of formula evaluation longer.
For this reason, it is important to make the formula evaluation run as fast as possible. When the respond of a formula that hasn’t been completely evaluated yet is late, the default value can be accepted as a respond and cause wrong actions.
What if a Formula is not Evaluated?
When the respond of a formula that hasn’t been completely evaluated yet is late, the default value can be accepted as a respond and cause wrong actions. Moving on to the next action before the formula evaluation is complete will cause incorrect results. Which means that even the condition you’ve specified is met, since the respond came later it will look like it is not met. When the conditions don’t work as fast as they are supposed to, it is necessary to do actions and review formulas to manage the screens in which formulas run.
How Should the Formulas Be Managed?
- An evaluation screen should be created for the formulas.
- Like we always mention, it is very important to pay attention to naming correctly. The Label in which the formula is evaluated should be named based-on what it does and the outcome it creates.
- The formula should produce 1 and as a result when it is used with the If function.
- Since actions like OnSelect, OnVisible,OnScan are instant actions, the formulas that has a long duration should be calculated outside with labels and be run with 1,0 control only.
