Hi,
i try to extend the SalesConfirmation and SalesInvoice report, and therefore created a new table, extended the data provider, all that worked well.
But when i wanted to add fields from the new dataset to the lines section in the report by a tablix, i was not allowed to change the datasource. In some posts i read to use a subreport instead, but when i added the subreport to the tablix, i have no dropdown in the "Use this report as a subreport:"-field, and whatever i enter there manually is not accepted.
Error message: "The report definition for report '{Reportname}' has not been specified"
I tried different notations: xyzReport, xyzReport.Designname, DynamicsAX.xyzReport.Designname etc
Can anyone tell me please, if it is possible to add a subreport to the formletters (e.g. SalesConfirmReport), and what i have to do to get a drop down in that field, or which notation i need to put a report name there.
Thanks,
harald
