Is any way in which we can download all the attachment from posted Purchase invoices at once?

    Standard page action is like this:

    action(Preview)

               {

                   ApplicationArea = All;

                   Caption = 'Preview';

                   Image = Export;

                   Promoted = true;

                   PromotedCategory = Process;

                   PromotedIsBig = true;

                   Scope = Repeater;

                   ToolTip = 'Get a preview of the attachment.';

                   trigger OnAction()

                   begin

                       if "File Name" <> '' then

                           Export(true);

                   end;

               }

    Potentially you could add a new version of this but have setselectionfilter and then loop on the results with the Export() function

    Hi Josh,

    Not able to figure out how this could be done.I am trying various ways not able to get it right.

    Adding to Josh's guideline 

    See the following by yzhums . I know it is a guideline for different purposes but it may give you an idea.

    Hi Mahgah,

    I tried with these guidelines only.

    If you see the code is in line with the suggestion.

    ZipFileName := 'Attachments_' + Format(CurrentDateTime) + '.zip';

           DataCompression.CreateZipArchive();

           docAttached.Reset();

           docAttached.SetRange(JobNo, Rec."Job No.");

           docAttached.SetRange(JobTaskNo, Rec."Job Task No.");

           docAttached.SetRange("Table ID", 122);

           docAttached.SetRange("No.", docno);

           if docAttached.FindSet() then begin

               Page.Run(1173, docAttached);

               repeat

                   TempBlob.CreateOutStream(DocumentStream);

                   RecRef.GetTable(docAttached);

                   FldRef := RecRef.Field(docAttached.FieldNo("No."));

                   FldRef.SetRange(docAttached."No.",);

                   if RecRef.FindSet() then begin

                       repeat

                           TempBlob.CreateInStream(IStream);

                           docAttached."Document Reference ID".ExportStream(DocumentStream);

                           FullFileName := Format(docAttached."File Name" + '.' + docAttached."File Extension");

                           DataCompression.AddEntry(IStream, FullFileName);

                       until RecRef.Next() = 0;

                   end;

               until docAttached.Next() = 0;

               Tempblob.CreateOutStream(DocumentStream);

               DataCompression.SaveZipArchive(DocumentStream);

               TempBlob.CreateInStream(IStream);

               DownloadFromStream(IStream, '', '', '', ZipFileName);

           end;

    This is the code.

    Thanks,

    Indira

    Hi All,

    Got a solution to this.

    the variable Temblob was not getting cleared in th begining of the loop and hence the issue was occuring.It works fine now.

    Thank you for all the help
