The added field in the database
enter image description here
He added the field in the database and then I generated my extension.
namespace PX.Objects.CR
{
public class PMQuoteExt : PXCacheExtension<PX.Objects.CR.CRQuote>
{
#region UsrNota
[PXDBString(-1, InputMask = "", BqlField = typeof(PMQuoteStandaloneExt.usrNotaText))]
[PXUIField(DisplayName = "Nota ")]
public virtual string UsrNotaText { get; set; }
public abstract class usrNotaText : IBqlField { }
#endregion
}
public class PMQuoteStandaloneExt : PXCacheExtension<PX.Objects.CR.Standalone.CRQuote>
{
#region UsrNota
[PXDBString(-1, InputMask = "")]
[PXUIField(DisplayName = "Nota ")]
public virtual string UsrNotaText { get; set; }
public abstract class usrNotaText : IBqlField { }
#endregion
}
}
public class PMQuoteMaint_Extension : PXGraphExtension<PMQuoteMaint>
{
public PXSelect<PX.Objects.CR.Standalone.CRQuote> Test;
}
However, when I record, it does not fill the field.
that I am making a mistake or doing wrong.
Can you tell me please.
Thank you

Answer 1

PMQuote is not an actual DB table, but a BQL projection between tables:
CR.Standalone.CRQuote
CROpportunityRevision
CR.Standalone.CROpportunity
The way that I would tackle this is:
Add the field in table CRQuote
Extend the graph and override the Projection with the inclusion of the new CRQuote field.
UPDATE:
Based on #HB_Acumatica suggestion, step 2 would get simplified to a DAC extension (no need for the Graph extension). Much simpler to maintain in subsequent Acumatica versions!
UPDATE 2:
The extended DACs do not look correct in your question. Keep in mind that you should extend the original table (CRQuote), and the projection in order to have the value persisted.
The following definition worked correctly on my end:
//Projection extension
public class PMQuoteExt : PXCacheExtension<PMQuote>
{
#region UsrCustomField
[PXDBString(100, BqlField = typeof(CRQuoteExt.usrCustomField))]
[PXUIField(DisplayName="Custom Field")]
public virtual string UsrCustomField { get; set; }
public abstract class usrCustomField : IBqlField { }
#endregion
}
//Actual Table extension
public class CRQuoteExt : PXCacheExtension<PX.Objects.CR.Standalone.CRQuote>
{
#region UsrCustomField
[PXDBString(100)]
[PXUIField(DisplayName="Custom Field")]
public virtual string UsrCustomField { get; set; }
public abstract class usrCustomField : IBqlField { }
#endregion
}
