CRM 2011 Postcode Lookup Solution Version 2.0

This is an extension of a blog I wrote back in June 2011. Here is the link to that blog. There were a few cons to that solution. One of the biggest cons was that the solution was hard coded to fill, only the built-in adress1_city, address1_stateorprovince, address1_country fields. I have updated the code to fill the city/suburb, state and country values to any field including custom fields. These fields have to be text fields.
The updated solution will work with the existing built-in entities as well as the custom entities.Here is the link to download the solution.
The solution consists of 4 files:

• new_Json2.js (Javascript webresource)
• new_PostCodeScript(Javascript webresource)
• new_postcode(custom entity to store postcode information)
• new_SuburbOptions (HTML webresource)

How does it work:

• User enters the postcode on postal code field and on onchange event of the field. The solution will retrieve postcode records related to entered postcode.
• If there is only one record related to entered postcode, the solution will populate the state, suburb and country fields for you.
• If there are more than one records related to entered postcode, the solution will prompt you to select the appropriate entry.

In the following screen shot, I entered 2000 in postal code field and system prompt to pick the relevant city/suburb.

Installation Directions:

1. Install the postcode solution.
2. Open the CRM entity form in customization mode.
3. Double click on attribute that represents the postalcode attribute.
4. Add new_Json2.js and new_PostCodeScript to form libraries.
5. Call loadPostCodeRequest function from new_PostCodeScript. Check the  “Pass execution context as first parameter” and pass the 3 attributes that represent the city, state and country attributes in “Comma separated list of parameters that will be passed to the function” as shown in the following screen shot.
6. Save the changes and publish the entity.
7. Test the solution.
