Reference lookup for Customer delivery address

I have a  requirement to get Customer Delivery Address in my form .

I have Customer field in my table and need to get all the delivery addresses for that customer as lookup to select for the new address field added.

Added a new field - Drag and drop ( sales line - delivery postal address field ).

maintain relation :  Table.DeliveryPostalAddr == LogisticsPostalAddress.Recid.

Add the field to form at required position. 

AutoDeclaration - yes to Reference Group. 

Properties :

data source - Inventlocation

ReferenceField : DeliveryPostalAddr

ReplacementFieldGroup - Location Reference.

Override Lookup reference method 

public Common lookupReference() {     CustTable                   custTable;     DirPartyTable               dirPartyTable;     DirPartyLocation            dirPartyLocation;     LogisticsPostalAddress      logisticsPostalAddress;     SysReferenceTableLookup     sysRefTableLookup;     Query                       lookupQuery = new Query();     QueryBuildDataSource        lookupQueryDataSource;     // Construct the SysRefTableLookup object     sysRefTableLookup = SysReferenceTableLookup::newParameters(tableNum(LogisticsPostalAddress),ReferenceGroup);     // Add the field list that will be displayed on the lookup form    // You can Change/Add more fields in lookup based on your requirement.     sysRefTableLookup.addLookupfield(fieldNum(LogisticsPostalAddress, Address));     sysRefTableLookup.addLookupfield(fieldNum(LogisticsPostalAddress, Location));     // Construct the query's data source     lookupQueryDataSource = lookupQuery.addDataSource(tableNum(LogisticsPostalAddress));  // To add multiple values in range.     while select  Location from LogisticsPostalAddress         join DirPartyLocation         join dirPartyTable         join custTable             where logisticsPostalAddress.Location == dirPartyLocation.Location                 && dirPartyLocation.Party == custTable.Party                 && custTable.Party == DirPartyTable.RecId                 && custTable.AccountNum == InventLocation.citCustAccount     {         // Add ranges to the query data source         lookupQueryDataSource.addRange(fieldNum(LogisticsPostalAddress, Location)).value(queryValue(LogisticsPostalAddress.Location));     }     // Pass the query to the lookup object     sysRefTableLookup.parmQuery(lookupQuery);     return sysRefTableLookup.performFormLookup(); }

Before writing custom lookup first you have to add reference control in your form and you have to specify some properties as shown in the screen shot below,
