Question

我已使用新的UsrAccountType字段扩展了业务帐户DAC。通过业务帐户维护图更新该字段时，我还需要更新相关客户记录中的各个字段。但是，当持续存在＆＃34;错误＃91：另一个进程已更新＆＃39; BAccount＆＃39;记录。您的更改将会丢失。＆＃34;发生。

首先，我只是尝试将Customer.customerClassID字段设置为与Account Type相同的值，Account Type是Customer Classes＆amp;的一个子集。与更改客户类相关的其他字段的更改无需应用。

public class BusinessAccountMaint_Extension : PXGraphExtension<BusinessAccountMaint>
{
    public PXSelect<Customer, Where<Customer.bAccountID, Equal<Current<BAccount.bAccountID>>>> ARCustomer;

    public virtual void BAccount_UsrAccountType_FieldUpdated(PXCache sender, PXFieldUpdatedEventArgs e)
    {
        BAccount row = (BAccount)e.Row;
        if (row == null) return;
        BAccount_Extension rowExt = row.GetExtension<BAccount_Extension>();

        Customer customer = ARCustomer.Current;
        if (customer == null) return;

        customer.CustomerClassID = rowExt.UsrAccountType;
        // additional changes to Customer record
        this.Base.Caches<Customer>().Update(customer);
    }
}

如何在BAccount的同时更新客户？我是否需要创建一个CustomerMaint图并通过它更新记录 - 这是否会导致两个记录同时更新时出现同样的问题？或者可以在持有BAccount更改并在那里完成对客户的更改后，在BAccount_RowPersisted中完成某些操作？

此行为的根本原因是客户来自BAccount。

[PXCacheName(Messages.Customer)]
[PXEMailSource]
public partial class Customer : BAccount, PX.SM.IIncludable
{

因此，如果您更新客户记录，BAccount记录也将更新。

要绕过这一点，您必须创建自己的客户DAC，而不是从BAccount派生并更新它。

namespace  SomeNamespce
{
     [Serializable]
    public partial class Customer : IBqlTable
    {
        public abstract class bAccountID : PX.Data.IBqlField
        {
        }
        [PXDBIdentity((IsKey = true))]
        public virtual int? BAccountID
        {
            get;
            set;
        }
        public abstract class customerClassID : PX.Data.IBqlField
        {
        }
        [PXDBString(10, IsUnicode = true)]
        //[PXDefault(typeof(Search<ARSetup.dfltCustomerClassID>))]
        //[PXSelector(typeof(CustomerClass.customerClassID), DescriptionField = typeof(CustomerClass.descr), CacheGlobal = true)]
        public virtual String CustomerClassID
        {
            get;
            set;
        }
    }
}
namespace  YourNamespace
{ 
    public class BusinessAccountMaint_Extension : PXGraphExtension<BusinessAccountMaint>
    {
        public PXSelect<SomeNamespce.Customer , Where<SomeNamespce.Customer.bAccountID, Equal<Current<BAccount.bAccountID>>>> ARCustomer;

        public virtual void BAccount_UsrAccountType_FieldUpdated(PXCache sender, PXFieldUpdatedEventArgs e)
        {
            BAccount row = (BAccount)e.Row;
            if (row == null) return;
            BAccount_Extension rowExt = row.GetExtension<BAccount_Extension>();

            SomeNamespce.Customer customer = ARCustomer.Current;
            if (customer == null) return;

            customer.CustomerClassID = rowExt.UsrAccountType;
            // additional changes to Customer record
            ARCustomer.Update(customer);
        }
    }
}

从BAccountMaint扩展更新客户（错误＃91另一个进程已更新..）
