OpportunityLineItem doesn't support getPicklistValues in lwc

OpportunityLineItem does not support getPicklistValues in Lightning Web Components #lwc

As per the documentation, recordTypeId  is required for getPicklistValues method in lighting uiObjectInfoApi. But there are some objects in salesforce which don't support record type, like OpportunityLineItem. So I tried passing null, blank values as recordTypeId  , but it doesn't work.


The below code doesn't work.

import { LightningElement, wire } from 'lwc';
import { getPicklistValues } from 'lightning/uiObjectInfoApi';
import SUB_TYPE from '@salesforce/schema/OpportunityLineItem.SBQQ__SubscriptionType__c';

export default class LwcGetpicklistDemo extends LightningElement {
    @wire(getPicklistValues, { recordTypeId: undefined, fieldApiName: SUB_TYPE })
    propertyOrFunction;
}

So I have done the workaround for it by using the apex aura enabled method as below.

Here is the Apex Code

@AuraEnabled(cacheable=true)
public static List<SelectOption> getOppItemPickListValues(String fieldApiName){
    List<SelectOption> pickListValuesList= new List<SelectOption>();
    if(string.isNotBlank(fieldApiName)){
        Map<String, Schema.SObjectField> fieldsMap= OpportunityLineItem.getSobjectType().getDescribe().fields.getMap();
        List<Schema.PicklistEntry> ple = fieldsMap.get(fieldApiName).getDescribe().getPicklistValues();
        for(Schema.PicklistEntry pickListVal : ple){
            pickListValuesList.add(new SelectOption(pickListVal.getValue(),pickListVal.getLabel()));
        }
    }
    return pickListValuesList;
}

Here is the sample JS code.

import { LightningElement, wire } from 'lwc';
import SUB_TYPE from '@salesforce/schema/OpportunityLineItem.SBQQ__SubscriptionType__c';
import getOppItemPickListValues from '@salesforce/apex/DirectSalesCompController.getOppItemPickListValues';

export default class LwcGetpicklistDemo extends LightningElement {
    @wire(getOppItemPickListValues, {
        fieldApiName: SUB_TYPE.fieldApiName
    })
    typePicklistValues;
}

 Here is the sample HTML code.

<template if:true={typePicklistValues.data}>
    <lightning-combobox label="Subscription Type" value={dropPipeJSLProduct.SBQQ__SubscriptionType__c}
        placeholder="-Select-" options={typePicklistValues.data}
        onchange={handleSubscriptionType}></lightning-combobox>
</template>

This is just a workaround and not a standard solution, lets wait for the salesforce team to update with the standard solution for the same.
