I wanna save multiple pdf files in my local computer, So I used this method inside a codeunit and call it from a page:

DOWNLOADFROMSTREAM

for i := 0 to 10 do begin
    // code to generate PDFs...
    TempBlob.CreateOutStream(pdfOutStream);
    FromBase64StringToStream(itemPDF, pdfOutStream);
    TempBlob.CreateInStream(pdfInStream);
    DownloadFromStream(pdfInStream, '', '', '', itemName);
end;

I run this code more than one time, But each time it download ONLY the first one PDF, but others don't want to be downloaded !?

I don't know why this happen?

is there another way/method to do that!?

Hi,

You can't download all PDF altogether, it will only download the first file only. To achive this you have to create them as Zip file and download that zip file.

Please have a look below url.

Hi Yun Zhu,

I follow your code it works perfectly.

but is there any limitation max file size?

if only 5-10 records ok.

but I have 500 records (which each record need to generate 3 pdf files).

some of the pdf file created are blank / cant open / starts from page 2.

- File Empty

File Cant Open

any idea?

Hi YUN ZHU,

I followed your code but it will download as zip file but the pdf files are blank. How can i fix it.

As the below screenshot all the pdf files are blank except the last pdf

procedure BulkDownloadInvoice(var SalesInvoiceHeader: Record "Sales Invoice Header")

var

TempBlob: Codeunit "Temp Blob";

OutS: OutStream;

InS: InStream;

RecRef: RecordRef;

FldRef: FieldRef;

RecordCounter: Integer;

DataCompression: Codeunit "Data Compression";

FileManagement: Codeunit "File Management";

ZipFileName: Text;

PdfFileName: Text;

begin

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

DataCompression.CreateZipArchive();

if SalesInvoiceHeader.FindFirst() then begin

repeat

Commit();

TempBlob.CreateOutStream(OutS);

RecRef.GetTable(SalesInvoiceHeader);

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

FldRef.SetRange(SalesInvoiceHeader."No.");

if RecRef.FindFirst() then begin

Report.SaveAs(Report::"Posted Sales Invoice", '', ReportFormat::Pdf, OutS, RecRef);

TempBlob.CreateInStream(InS);

PdfFileName := 'Invoice No:' + Format(SalesInvoiceHeader."No.") + ' - ' + Format(SalesInvoiceHeader."Sell-to Customer Name") + '.pdf';

DataCompression.AddEntry(InS, PdfFileName);

end;

Sleep(1000);

until SalesInvoiceHeader.Next() = 0;

TempBlob.CreateOutStream(OutS);

DataCompression.SaveZipArchive(OutS);

TempBlob.CreateInStream(InS);

DownloadFromStream(InS, '', '', '', ZipFileName);

end;

end;
