Hi Kazuki,

 

If you use a datagrid in Mendix, inside the property lane you have the option to multi-select or simple multi select. After that place a microflow button in the toolbar, this will take the selection as a list parameter.

Sorry for the lack of explanation.
What I want to do is to select multiple items from entity 1 imported from excel and tie them to entity 2 created on a separate creation page, as shown in the image below.
I wasn't sure what kind of logic to put in place in microflow to do this kind of processing.

Hi Kazuki Abe,
Approach  1: Create a Many to Many Association between Entity 1 and Entity 2. 

Now add a reference set Selector in Page of Entity A to select multiple entries at once.

 

From your Diagram, I can also Think of 1- many associations. 

Approach 2 : 
You can use a One-Many association between Entity A and Entity B – One Entity 2 object has many Entity 1 objects. 
The parent is Entity 1.
In this was you can use a Reference Selector form page of Entity A. 

 

 

Note: If you want to Multiselect you can use the first method.

           if a single Select is enough but Want the Achieve the data model explained above you can the second  Approach.
