• In the Power Apps Maker Portal, find the solution containing the entities and forms for which you want to configure Express Entry Autocomplete control. 
• Open the Account table, and find the form you want to use Address Autocomplete on
• Open the form you want to edit and click on “Switch to classic” in the command bar
• In the classic configuration screen, add the Address Street Line 1 of the form and click on Change Properties in the ribbon to access the Field Properties screen.
• In the “Display” area, uncheck the “Display label on form” checkbox
• Next go the Controls Tab and add the control named "Melissa Data Express Entry Autocomplete" and select the devices where you want the control to be displayed. 

• Once you have selected the control, you need to provide a value for required properties (identified with a * in the table below); all the other properties are not mandatory :

Property	Description	Field Type
API Configuration Name *	This refers to your API Configuration unique record name.	Static Text Value
Advanced Setting ID	If you are using Advanced Control Settings, you need to put the Identifier of your Advance Setting record here.	Static Text Value
Display Address Fields	The control can display the address fields under the address search control. Set the value to YES to display these fields. This is a legacy feature. We recommend setting the value to NO and displaying individual address fields yourself.	Single Line of Text

Unit Number	Column where you want to store the Unit or Suite number.	Single Line of Text
City *	Column where you want to store the city.	Single Line of Text
State *	Column where you want to store the state or province name.	Single Line of Text

Default Country	When the form is loaded, this country will be selected by default. Enter one country's ISO 3166-1 alpha-2 code (i.e. US, CA, MX, etc.)	Static Text Value
Display Countries	List of countries that will be available in the user interface for selection. Type the countries using their ISO 3166-1 alpha-2 code (i.e. US, CA, MX, etc.). To display more than one country, type them by separating them with a comma "," without blank spaces (i.e. US,CA,MX).	Static Text Value
Top Countries	These countries will be pinned to the top of the list (most frequently used countries). Type the countries using their ISO 3166-1 alpha-2 code (i.e. US, CA, MX, etc.). To display more than one country, type them by separating them with a comma "," without blank spaces (i.e. US,CA,MX). To set a 'Default Country' or 'Top Country', it must first be added in the ‘Display Countries’ property as well. If a country is saved on the address column (by a background process) and it is not configured in the 'Display Countries' property, the data will be saved, but it will no appear in the address control.	Static Text Value

• Click OK, save the form and publish it.
• Open your account and test your control

Advanced Control Settings allow administrators to configure additional parameters for the address autocomplete control. These parameters are useful for organizations that require their state or provinces to be captured in a specific format. For example, if ISO2 country codes are required, it can be specified in the advanced settings. 

• To get started, find the Advanced Settings by navigating to the Address Validation for Power Apps application and select the “Address Control Settings” menu. Click + New to create a new record.
• Set the required values 
  • Identifier : Unique Identifier of the Setting. This will be used in the control's configuration on the form. 
  • API Type : Select Melissa
• List of parameters available for Melissa :

Parameter	Possible Values	Description
Return PO Boxes	Yes / No	US Only. Enables autocomplete control to return PO Boxes along with addresses.  By default, it is set to Yes (i.e. if no setting is present, PO Boxes are returned by Express Entry)
Include Extended Postal Code	Yes / No	Allows to add the +4 section of the zip code when available.   By default, it is set to Yes (i.e. if no setting is present, extended postal codes are returned by Express Entry)
Country Display	Use ISO2 Country Code Use ISO3 Country Code *** Use Long Country Name	--> CA --> CAN --> Canada

Important Note : these parameters are saved on your end-users' local cache. If you make changes to them, they will need to clear their browser cache for them to be reflected in their usage of Express Entry autocomplete in Dataverse.

Assign the required security privileges to users

Once the configuration is completed, you need to assign the required security roles to your end users to allow them to use the autocomplete controls. Refer to this article for details on how to achieve this.
