Perdon, me olvide de poner el fuente corecto. Este es el fuente de CriaComponente. Estas en mi servidor de aplicaccion.

procedure TRDM_Consulta.CriaComponente(qtdCampoChave: Integer; nmTabela,
SQL: string);
var
qry: TSQLQuery;
dsp: TDataSetProvider;
begin
qry := TSQLQuery.Create(Self);
dsp := TDataSetProvider.Create(Self);
qry.Name := 'qry' + nmTabela;
dsp.Name := 'dsp' + nmTabela;
qry.SQLConnection := qryGeral.SQLConnection;
qry.SQL.Text := SQL;
dsp.DataSet := qry;
dsp.Exported := True;
dsp.UpdateMode := upWhereKeyOnly;
dsp.Options := dsp.Options + [poAllowCommandText];

case qtdCampoChave of
1: qry.AfterOpen := qryAfterOpen1Key;
2: qry.AfterOpen := qryAfterOpen2Key;
3: qry.AfterOpen := qryAfterOpen3Key;
4: qry.AfterOpen := qryAfterOpen4Key;
5: qry.AfterOpen := qryAfterOpen5Key;
6: qry.AfterOpen := qryAfterOpen6Key;
7: qry.AfterOpen := qryAfterOpen7Key;
8: qry.AfterOpen := qryAfterOpen8Key;
end;

dsp.OnDataRequest := dspDataRequestParam;
end;

Em mi client yo paso los valores del Sql:

if (dMov <> '') and (nCoo <> '') and (sCompNEmitido <> '') then

DM_Create.ConectaMatriz;
with DM_Create.CDS_CapeReducao do

Execute;

Cambie todos por String, pero el eror es el mismo. Si yo paso directo CommandText, con los mismos valores, funciona. Pero por parametro y el CommandText en el Servidor de Aplicacion, entonces no funciona.
