Configuring a Lookup Field


You can configure Lookup Fields to map fields from one application to another. Lookup fields are a one time pull of data from a datasource app, into fields in another "destination" app.

Please note:

  • If data in a record in the datasource app is updated, the record in the destination app will not automatically update. You must navigate back to the destination app, edit the record, click Lookup again, and click Save.

What is Lookup?

Lookup autofills data from one app to another. This saves the trouble of entering data and also prevents inputting errors. 


Let's say a lookup function has been set for a project management app to allow the app to refer to a customer management app. This will allow you to retrieve any customer information and copy it into the project management app.

How to lookup information with a Lookup Field:

  1. From a record, enter the partial string of a customer name into the Lookup field, and click "Lookup". The list of customer names that match the partial string entered will be displayed. 
  2. Select the customer whose information you want to be copied to the project management app. The information for that specific customer will automatically be entered into the form of the app. 

Data copied with the lookup feature is saved independently from the source app. Even if parts of data are changed or deleted in the source app, data that was previously retrieved is retained until a user clicks Lookup within the record again.

  • If there is only one customer that matches the partial string entered in step 1, the customer list in step 2 is not displayed. When you click “Lookup", the customer information is automatically be entered on the form.
  • If you do not provide any string in step 1 and click "Lookup", all customers are displayed. In the same way as in step 2, you can select a customer to retrieve the data.
  • Only one keyword can be specified in step 1. Multiple keywords cannot be specified. In addition, search keywords have the same limitations as the search bar feature.


This error message Screen_Shot_2019-06-03_at_11.27.23_PM.png is displayed in one of the following situations:

  • If you try to save the record when Lookup field is required, but there was no data lookup.
    • Solution: Click "Lookup" to retrieve data, and then save the record.
  • When a search keyword is entered in the lookup field and the data is not retrieved.
    • Solution: Delete the entered keyword, or click "Lookup" to retrieve data, and then save the record.
  • Please note: If the error message is still displayed, data that is referred by the lookup field may include a line break character. A line break character appears as a space. When you open the "Edit Record" screen for the record that is referred by the lookup field and save it without any change, the line break character is automatically removed.
