To create records for each objects we are using Navigation Mixin, But we tried searching the product field in the Opportunity Product we are facing some salesforce error which are attached below.enter image description here

A solution we tried for this problem by using lightning-record-edit-form which is working fine, But in our scenario we are pre-populating some of our fields during the page load and which can't be done using lightning-record-edit-form.

Any workaround for this?

You can try this below code which will create/prepopulate the values that could be invoked from any record page and prepopulate default values on the record creation screen of a different Object

This goal emanated from the need to create a custom object record from the Opportunity record, via clicking a quick action, prepopulating the values from the Opportunity on the record creation screen before the record actually got created by the user clicking 'Save' within the modal.

The solution uses a custom metadata type for the field mapping (to map source object to default value on destination object).

enter image description here


// LWC used to prepopulate values on a record creation modal, invoked from a quick action
// Note: this LWC depends on the quick action API name being in the following format:
//  ObjectName_XXXXX_QuickActionName

//  Example: Quote_Request_c_XXXXX_New_Quote_Request_V2
// Note: if dealing with custom object, you cannot use __c in the naming convention above due to
//  Salesforce system limitation.

import getFilesOnRecord from "@salesforce/apex/ApexUtils.getFilesOnRecord";
import { CurrentPageReference } from "lightning/navigation";
import { NavigationMixin } from "lightning/navigation";

export default class DefaultValuesComponent extends NavigationMixin(
) {
sObjectApiName = "";
quickActionAPIName = "";
retrievedRecordId = false;
  getStateParameters(currentPageReference) {
    // if the page is a quick action, get quick action API name
    if (currentPageReference.type === "standard__quickAction") {
      let quickActionPath = currentPageReference.attributes.apiName;
      let firstSplit = quickActionPath.split(".")[1];
      let sObjectApiName = firstSplit.split("_XXXXX_")[0];
      if (sObjectApiName.includes("_c")) {
        sObjectApiName = sObjectApiName.replace("_c", "__c");
