Updating Lookup Fields in JavaScript using Xrm.WebApi

In this post, we will look at how to update Lookup Fields in a Dynamics 365 Power Apps record using the Xrm.WebApi.

Let’s say we have an Opportunity record. This record has 3 lookup fields:

• Contact
• Account
• Currency

For simplicity, let’s hardcode the Ids of the new records we will be associating to our Opportunity:

• Our new Contact called Maria Campbell is c0993617-c85d-ea11-a811-000d3a579ca1
• Our new Account called Blue Yonder Airlines is 5c993617-c85d-ea11-a811-000d3a579ca1
• Our new Currency Euro is 1C2A5F41-0D5C-EA11-A811-000D3A5694CA

And the Opportunity we’re updating is 8a9a3617-c85d-ea11-a811-000d3a579ca1.

Note on the Opportunity, our fields have the following names:

• Contact = parentcontactid
• Account = parentaccountid
• Currency = transactioncurrencyid

These fields are of entity types Contact, Account and Transaction Currency, respectively.

Now the code. We will use the notation fieldname@data.bind: “/entitypluralname(Id)” in our object to update our record:

var ContactId = "c0993617-c85d-ea11-a811-000d3a579ca1";
var AccountId = "5c993617-c85d-ea11-a811-000d3a579ca1";
var CurrencyId = "1C2A5F41-0D5C-EA11-A811-000D3A5694CA";
var OpportunityId = "8a9a3617-c85d-ea11-a811-000d3a579ca1";

var UpdateObject = {
    "parentcontactid@odata.bind": "/contacts(" + ContactId + ")",
    "parentaccountid@odata.bind": "/accounts(" + AccountId + ")",
    "transactioncurrencyid@odata.bind": "/transactioncurrencies(" + CurrencyId + ")" 
};

Xrm.WebApi.updateRecord("opportunity", OpportunityId, UpdateObject).then(
    function success(result) {
        console.log("success"); 
    },
    function error(result) {
        console.log(result);                            
});

When we run this, we get a Success:

And on refreshing our record we see the lookup fields have been updated.
