Hi, all
I create PXCacheExtension<PMProformaLine> and add new custom field.
Next i override method BillTask.
In this method base functional create
PMProformaTransactLine line = new PMProformaTransactLine();
And when i try this AKTPMProformaLineExt lineExt = line.GetExtension<AKTPMProformaLineExt>();
I get this error. GetItemExtension failed.
Solved
GetExtension failed

Hi
Database table - PMProformaLine
CacheExtension - PMProformaTransactLine
PMProformaTransactLine line = new PMProformaTransactLine();
// logic
line = ProformaTransactDetails.Insert(line);
and then use AKTPMProformaLineExt lineExt = line.GetExtension<AKTPMProformaLineExt>();
I think it should work, if not please share the your CacheExtension DAC and GraphExtension code as well, if possible.

Hi
The GetExtension failed error happens because PMProformaTransactLine and PMProformaLine are treated as separate DACs. Extensions are registered per DAC type, so an extension targeting PMProformaLine will not be found on a PMProformaTransactLine object.
To fix this, create an extension specifically for PMProformaTransactLine:
public class AKTPMProformaTransactLineExt : PXCacheExtension<PMProformaTransactLine>
{
[PXDBString(10)]
[PXUIField(DisplayName = "Custom Field")]
public string UsrCustomField { get; set; }
public abstract class usrCustomField : PX.Data.BQL.BqlString.Field<usrCustomField> { }
}
Then, access it in your code using the new class name:
var lineExt = line.GetExtension<AKTPMProformaTransactLineExt>();
if (lineExt != null)
{
string value = lineExt.UsrCustomField;
}
