Why set Minimum and Maximum Records?
On an Actionflow's 
input connection point(s), a minimum and maximum number of records that should be received by the Actionflow can be set. If the number of records received is not within the set minimum/maximum threshold, an error message will show.
This can be useful for:
- Ensuring at least one record is selected before proceeding with an edit
Setting Minimum and Maximum Records
- Click on the input node to open its
Properties tab - Expand the Validation section
- Enter a number for Minimum Records and/or Maximum Records
Apply and Close the properties
Worked Example
Here's a worked example using the Shop Data (available from the Learning Centre).
In this example, we are using:
- A Shop Staff screen containing a grid of the Shop Staff data - this screen was created using the Tile with Buttons template
If you are completing this chapter as part of the Actionflow course and using a training instance, the data and screens have already been pre-loaded into the Actionflow Intermediate Application. For this example, we'll be working on the grid on the Shop Staff screen.
