25 R1 - Auto Numbering is NOT working for Custom field in Custom screen

make sure this field has a  value in the preference screen. NBBLINSetupExt.usrNBBLNumberingID

The code itself looks ok. The issue may be somewhere else, e.g. data not being entered in the setup field or UI definition.

Do you also have a constructor for the graph where you are forcing the graph to call the view where your custom autonumber code resides? e.g.
 

INSetup inSetup = AutoSetupView.Current;

NBBLINSetupExt inSetupExt = inSetup.GetExtension<NBBLINSetupExt>();

Hi ​@nsmith51
Try adjusting your PXDBString attribute by adding the InputMask property as shown below:

[PXDBString(15, IsKey = true, IsUnicode = true, InputMask = ">CCCCCCCCCCCCCCC")]

Additionally, make sure that the Numbering Sequence you entered in the NBBLINSetupExt.usrNBBLNumberingID field has the Manual Numbering checkbox unchecked:

Yes, configured properly at Inventory Preferences screen.

Any field in the screen when I enter the value and tab it and it is clearing automatically.

When I try to delete old records also getting below error.

 

​@nsmith51  the Primary Graph of your DAC is having “1” in the end.

[PXPrimaryGraph(typeof(NBBatchLabelMaint1))]

but you have this graph - NBBatchLabelMaint .

  public class NBBatchLabelMaint : PXGraph<NBBatchLabelMaint, NBBLCBatchLabel>
  {

      public SelectFrom<NBBLCBatchLabel>.View NBBLCHeaderView;

      public SelectFrom<NBBLCLabelItems>
          .Where<NBBLCLabelItems.batchNbr.IsEqual<NBBLCBatchLabel.batchNbr.FromCurrent>>
          .View NBBLCDetails;


      public PXSetup<INSetup> AutoSetupView;

}

​@palbores Sorry. That I have added by mistakenly. I don’t have that in my code.

Can anyone please give me the idea that why field value is clearing when I enter a value in header fields?

There is something wrong in this DAC - NBBLCLabelItems
 

 public SelectFrom<NBBLCLabelItems>
          .Where<NBBLCLabelItems.batchNbr.IsEqual<NBBLCBatchLabel.batchNbr.FromCurrent>>
          .View NBBLCDetails;

Here is the DAC for the NBBLCLabelItems.

For your NBBLCLabelItems.batchNbr field.

Change the PXParent

[PXParent(typeof(Select<NBBLCBatchLabel,Where<NBBLCBatchLabel.batchNbr, Equal<Current<batchNbr>>>>))

That did not help and value is still clearing from the header fields.
