Populate lookup field based on another lookup field on the form.

ReportReport
Posted on by DevCrmUser 60

I have two lookup on the form lets Say A  and B.

I need to populate B based on the value in A as A has a main form where this lookup B is populated with the value and that value should populate in my form where both this field are present

I cannot use mapping for it as B and A is 1:N related and user is not allowed to fill B first so that we can populate A. but vice versa is needed.

I hope I have cleared my requirements

Can i get any JavaScript sample code . I am pretty new to it so needed help

Thanks in advance.

    As my understand, you want to get the B from A's record and set value for B? here is a demo code for you, this function should bind to the OnChange event of A, you may need change some of the variables:

    function fieldAOnChange(executionContext) {
	var formContext = executionContext.getFormContext();
	// Get the value of lookup field A
	var lookupValue = formContext.getAttribute("lookupA").getValue();

	// Get the record associated with lookup field A
	var lookupRecord = lookupValue[0].id;

	// Retrieve the value of field B from the associated record
	Xrm.WebApi.retrieveRecord("entitynameA", lookupRecord, "?$select=new_fieldB").then(
		function success(result) {
			// Set the value of lookup field B
			formContext.getAttribute("lookupB").setValue([{ id: result.new_fieldB, name: result.new_fieldBName, entityType: "entitynameB" }]);
		},
		function (error) {
			console.log(error.message);
		}
	);
}
