PO Line Account field won't persist - acumatica

Question

On a PO, I can't seem to get a PO Line's Account field (ExpenseAcctID) to persist. The value appears in the UI normally, and when I check the value in the FieldUpdated, RowUpdated, and RowPersisted handlers, the field actually has a value. Somehow it's not persisting to the db. The field was customized as shown below. The field in the .ASPX is specified as a PXSelector. Any ideas?
[PXMergeAttributes(Method = MergeMethod.Replace)]
[PXRestrictor(typeof(Where<Account.active, Equal<True>>), PX.Objects.GL.Messages.AccountInactive)]
[PXRestrictor(typeof(Where<Where<Current<GLSetup.ytdNetIncAccountID>, IsNull,
Or<Account.accountID, NotEqual<Current<GLSetup.ytdNetIncAccountID>>>>>), PX.Objects.GL.Messages.YTDNetIncomeSelected)]

Acumatica needs the attribute [PXDBInt] to relate the field to the database. The original definition of the field in the DAC is:
#region ExpenseAcctID
public abstract class expenseAcctID : PX.Data.BQL.BqlInt.Field<expenseAcctID> { }
protected Int32? _ExpenseAcctID;
[Account(typeof(POLine.branchID),DisplayName = "Account", Visibility = PXUIVisibility.Visible, Filterable = false, DescriptionField = typeof(Account.description), AvoidControlAccounts = true)]
[PXDefault(PersistingCheck = PXPersistingCheck.Nothing)]
public virtual Int32? ExpenseAcctID
{
get
{
return this._ExpenseAcctID;
}
set
{
this._ExpenseAcctID = value;
}
}
#endregion
The [Account] attribute contains the following attributes that are applied for you:
[PXUIField(DisplayName = "Account", Visibility = PXUIVisibility.Visible, FieldClass = DimensionName)]
[PXDBInt]
[PXInt]
[PXRestrictor(typeof(Where<Account.active, Equal<True>>), Messages.AccountInactive)]
[PXRestrictor(typeof(Where<Where<Current<GLSetup.ytdNetIncAccountID>, IsNull,
Or<Account.accountID, NotEqual<Current<GLSetup.ytdNetIncAccountID>>>>>), Messages.YTDNetIncomeSelected)]
By using [PXMergeAttributes(Method = MergeMethod.Replace)] in your cache_attached, all attributes within the DAC definition for that field are dropped and replaced with only what you define.
You switched to [PXDimensionSelector] which does not contain the attribute [PXDBInt]. That means Acumatica has no way of knowing that the field is intended to be tied to the database. You still have access to the field within the screen, but interactions between the cache and the database will skip this field.
To resolve, just add [PXDBInt] to your cache_attached as follows:
[PXMergeAttributes(Method = MergeMethod.Replace)]
[PXDBInt]
[PXRestrictor(typeof(Where<Account.active, Equal<True>>), PX.Objects.GL.Messages.AccountInactive)]
[PXRestrictor(typeof(Where<Where<Current<GLSetup.ytdNetIncAccountID>, IsNull,
Or<Account.accountID, NotEqual<Current<GLSetup.ytdNetIncAccountID>>>>>), PX.Objects.GL.Messages.YTDNetIncomeSelected)]
