Acumatica Extending PMProjectStatusEx - acumatica

Question

I am working on the Project Budget Screen of acumatica, the screen uses the table PMProjectStatusEx which is a Projection table of PMProjectStatus. So I extended the PMProjectStatus table and added a field in there, I also extended the PMProjectStatusEx to add the same field and added it to the screen. But unlike the standard fields that updates the physical table PMProjectStatus my added field does not update the physical table. What could be the reason for this? Below is my code
Thanks
public class PMProjectStatusExt :
PXCacheExtension<PX.Objects.PM.PMProjectStatus>
{
#region UsrMarkupPct
public abstract class usrMarkupPct : PX.Data.IBqlField
{
}
protected Decimal? _UsrMarkupPct;
[PXDBDecimal(6, MinValue = 0, MaxValue = 1000)]
//[PXDefault(TypeCode.Decimal, "0.0")]
[PXUIField(DisplayName = "Markup %")]
public virtual Decimal? UsrMarkupPct
{
get
{
return this._UsrMarkupPct;
}
set
{
this._UsrMarkupPct = value;
}
}
#endregion

When you add fields using the DATA ACCESS section of the Project Editor it will generate DB Scripts to update the table behind the scene:
When you add fields using a DAC extension in CODE section, it will not generate the DB Scripts.
In that case you need to manually add the scripts in DB Scripts section.
EDIT
One way to manually add DB field in DB Scripts is:
IF NOT EXISTS(SELECT * FROM Sys.Columns WHERE Name = N'UsrMarkupPct' and
Object_ID = Object_ID(N'PMProjectStatus'))
BEGIN
ALTER TABLE PMProjectStatus ADD UsrMarkupPct DECIMAL(19,6)
END
