Problem with delphi+ado+mdac 2.7 + sapdb 7.4

[Abaco Inform�tica S.A.]

Hi: We have a little problem when we update a query, the message is 'insufficient information for update or insert a row" . Our project is in delphi 5 an have a AdoQuery, a Datasource, dbgrid and a button which fired the query's updatebatch method. When we update data in a grid all is ok, but in the updatebatch the message is posted.   Can somebody help as?   tia. Ricardo Solanilla
