How to change to display more address fields in Sales Order Screen when selecting location

@ltussing03 ,  you just need to replace the LocationActive attribute for the SOOrder.customerLocationID field with the signature allowing joins and add the columnd using the additional PXCustomizeSelectorColumns attribute. 

Original attribute:

[LocationActive(typeof(Where<Location.bAccountID, Equal<Current<SOOrder.customerID>>,
			And<MatchWithBranch<Location.cBranchID>>>), DescriptionField = typeof(Location.descr), Visibility = PXUIVisibility.SelectorVisible)]

Needed attributes:

		[LocationActive(typeof(Where<Location.bAccountID, Equal<Current<SOOrder.customerID>>,
			And<MatchWithBranch<Location.cBranchID>>>),
			typeof(InnerJoin<Address, On<Address.addressID, Equal<Location.defAddressID>>>), DescriptionField = typeof(Location.descr), Visibility = PXUIVisibility.SelectorVisible)]
		[PXCustomizeSelectorColumns(typeof(Address.addressLine1), typeof(Address.city))] //here, you can specify the needed list of fields to display in the selector

In partucular, you need to create an Extension of SOOrder and do this replacement through the _CacheAttached event:

public class SOOrderEntryCommunity7713 : PXGraphExtension<SOOrderEntry>
{
		[PXMergeAttributes(Method = MergeMethod.Merge)]
		[PXRemoveBaseAttribute(typeof(LocationActiveAttribute))]
		[LocationActive(typeof(Where<Location.bAccountID, Equal<Current<SOOrder.customerID>>,
			And<MatchWithBranch<Location.cBranchID>>>),
			typeof(InnerJoin<Address, On<Address.addressID, Equal<Location.defAddressID>>>), DescriptionField = typeof(Location.descr), Visibility = PXUIVisibility.SelectorVisible)]
		[PXCustomizeSelectorColumns(typeof(Address.addressLine1), typeof(Address.city))] //
		protected virtual void SOOrder_CustomerLocationID_CacheAttached(PXCache sender)
		{
		}
}
