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 min/max threshold set then 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
For Input Connection Points the default Minimum Records is 1.
Worked Example
Here's a worked example using the Shop Data (available from the Learning Centre).
In this example, we are using:
- A Shop Stock screen containing a grid of the Shop Stock data, a pie chart of the Shop Stock data and a grid of the Shop Departments data - this screen was created using the Multi-Tile 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 Stock screen.
