Update customer children from parent account - acumatica

Question

Page: AR303000 Version:18.203.0006
Good day
I need to update the Child accounts details(Terms, Status, and Email) when the parent account changes. The problem is I do not know how to save the children Customer's contact email field from Customer_RowPersisting.
The customer child accounts do save a, but the Contact details do not.
namespace PX.Objects.AR
{
public class CustomerMaint_Extension : PXGraphExtension<CustomerMaint>
{
#region Event Handlers
protected void Customer_RowPersisting(PXCache cache, PXRowPersistingEventArgs e)
{
Customer row = (Customer)e.Row;
if (row.ParentBAccountID == null)
{
PXResultset<Customer> Children = PXSelectJoin<Customer,
LeftJoin<BAccount, On<Customer.bAccountID, Equal<BAccount.bAccountID>>>,
Where<BAccount.parentBAccountID, Equal<Required<Customer.bAccountID>>>>.Select(Base, row.BAccountID);
if (Children == null) { return; }
Contact ParContact = PXSelect<Contact, Where<Contact.contactID, Equal<Required<Contact.contactID>>>>.Select(Base, row.DefBillContactID);
foreach (Customer item in Children)
{
//Customer
item.TermsID = row.TermsID;
item.Status = row.Status;
cache.Update(item);
//Contact Details
Contact Cur = PXSelect<Contact, Where<Contact.contactID, Equal<Required<Contact.contactID>>>>.Select(Base, item.DefBillContactID);
Cur.EMail = ParContact.EMail;
cache.Update(Cur);
}
//Do not know if this is right
cache.Persist(PXDBOperation.Normal);
}
}

}

You can override the Persist() method! You should add a reference for the PX.CS.Contracts.dll dll.
public class CustomerMaintExt : PXGraphExtension<CustomerMaint>
{
#region Overrides
public delegate void PersistDelegate();
[PXOverride]
public void Persist(PersistDelegate baseMethod)
{
using (var scope = new PXTransactionScope())
{
Customer row = this.Base.BAccount.Current;
if (row?.ParentBAccountID == null)
{
CustomerMaint businessAccount = PXGraph.CreateInstance<CustomerMaint>();
PXResultset<Customer> Children = PXSelect<Customer, Where<Customer.parentBAccountID, Equal<Required<Customer.bAccountID>>>>.Select(Base, row.BAccountID);
foreach (Customer item in Children)
{
businessAccount.Clear();
businessAccount.BAccount.Current = PXSelectorAttribute.Select<Customer.bAccountID>(this.Base.BAccount.Cache, item.BAccountID) as Customer;
item.TermsID = row.TermsID;
item.Status = row.Status;
Contact defContact = PXSelect<Contact, Where<Contact.bAccountID, Equal<Required<BAccount.bAccountID>>, And<Contact.contactID, Equal<Required<BAccount.defContactID>>>>>.Select(businessAccount, item.BAccountID, item.DefContactID);
defContact.EMail = this.Base.DefContact.Current.EMail;
businessAccount.DefContact.Update(defContact);
businessAccount.BAccount.Update(item);
businessAccount.Save.PressButton();
}
}
baseMethod();
scope.Complete();
}
}
#endregion
