Khan AnasKhan Anas (Salesforce Developers) 

Hi Valli,

Greetings to you!

You can use the below code:
  
<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >
    
    <div class="slds-m-around_xx-large">
        <lightning:recordEditForm recordId="5007F00000SbdGaQAJ" objectApiName="Case">
            <lightning:messages />
            <lightning:inputField fieldName="AccountId"/>
            <lightning:inputField fieldName="ContactId"/>
            <lightning:inputField fieldName="Origin" />
            <lightning:inputField fieldName="Status" />
            <lightning:inputField fieldName="Priority" />
            <lightning:button class="slds-m-top_small" variant="brand" type="submit" name="update" label="Update" />
        </lightning:recordEditForm>
    </div>
</aura:component>

Replace recordId with your Case Id in above example.

When using lightning:inputField for the fields if type ‘reference’ (look up), lookup search does not load the modal for the first time. It works fine after we reload the page

If know issue  ..

Refer this code . *"0037F00000XXXXXXXX" should be recordId you need

  
<aura:component implements="force:appHostable" > 
<lightning:recordEditForm aura:id="recordEditForm" recordId="0037F00000XXXXXXXX" objectApiName="Contact"> 
<lightning:inputField fieldName="AccountId"/> 
</lightning:recordEditForm> 
</aura:component>

@Valli
Did you get your answer? 
I am creating new record using <lightning:recordEditForm>  and i am not able to populate lookup field onload finction. 
I tried below things but both are not working: 
1. 
<lightning:inputField aura:id="caseLookup" type='String'  fieldName ="Case__c" value="00842156"/>
2. 
<lightning:inputField aura:id="caseLookup" fieldName ="Case__c"/>
Controller:  
onload : function(component, event, helper) {
        var parentId = component.get("v.parentId");
        // requires inputFields to have aura:id
        component.find("caseLookup").set("v.value", "00842156");
    },
 
Please help me here, I can do it using custom component but i want to use this.

@Mrial Sharma
replace "00842156" with the case Id instead of case number
replace  component.find("caseLookup").set("v.value", "00842156"); with component.find("caseLookup").set("v.value", "<CaseId>");
