I have one question.

When we are sending parameter to getPicklistValues as per field, Then we are importing the field by schema and sending that as a parameter. we are not using directly the field API name.

Like - import ACCOUNT_SOURCE from '@salesforce/schema/Account.AccountSource';

using here - @wire(getPicklistValues, { recordTypeId : '012000000000000AAA', fieldApiName : ACCOUNT_SOURCE })

But when we are fetching a particular field's value from "getPicklistValuesByRecordType", We are using the API name of the field.

We are not importing the field by the schema.

Like this - this.pickListvaluesByRecordType = data.picklistFieldValues.Industry.values;

Here we are using the direct API name of the "Industry" field. We are not importing this field and use it.

Why SO??????

Thanks in Advance,
