help with BE (business ent) it no longer works

used to have:

USING procs.ventas.dsCasoDetalle FROM PROPATH.
{procs\ventas\inc\dscasoDetalle.i}


DEFINE INPUT  PARAMETER pControl AS DECIMAL NO-UNDO.
DEFINE OUTPUT PARAMETER DATASET  FOR dsCasoPaqDetalle.

DEFINE VARIABLE myCaso AS dsCasoDetalle NO-UNDO.


myCaso = NEW dsCasoDetalle().

myCaso:ReaddsCasoDetalle('control# = ' + string(pControl) , OUTPUT DATASET dsCasoPaqDetalle).

DELETE OBJECT myCaso.

and get on dataset some records to comply with control# = 50.3453  for instance...

but today cleaned Project and updated. and can't get to work that readdsCasoDetalle call.

I put a for each ttCasoPaqDetalle.  message tt...fields.  end.

after the call and the dataset came empty.

thiis is dscasoDetalle.i, I wonder if the primary key having  fecha as part of pk, has something related to this. (I guess it is what changed from previous verions,  but I'm not sure about it)

DEFINE TEMP-TABLE ttCasoPaqDetalle BEFORE-TABLE bttCasoPaqDetalle
    FIELD Control#    AS DECIMAL   INITIAL "0"
    FIELD Fecha       AS DATETIME
    FIELD Usuario     AS CHARACTER
    FIELD Observacion AS CHARACTER
    INDEX ControlFecha IS PRIMARY UNIQUE Control# ASCENDING Fecha ASCENDING . 


DEFINE DATASET dsCasoPaqDetalle FOR ttCasoPaqDetalle.

...

Any help would be appreciated.  Thanks.
