Converting PDF file into base64String in D365 Finance and operations

Posted on by Ishu.caddengg@hotma... 505

Hi All,

We are using Standard Business Event of Purchase Order Workflow for sending the Email notification through Microsoft Flow and get it approved through email.

Now I have to do customization for adding an attachment of report in WF notification. The idea is to add new field of type String in Business Events and then transfering the PDF file through Business Events to Microsoft Flow. For this

1) I have to convert(Encode) PDF file into base64String in D365 Finops

2)transfering to Flow through Business Events

3) Decoding the file from base64String to PDF in Microsoft Flow and send as attachment in Email Notification.

Could you please let me know, above solution is feasible or not and Code to convert PDF to Base64 in D365 finOps?

    Hi Ishu,

    You can convert PDF to Base64 through this code:

    System.Byte[] pdfDocBuffer;
System.IO.FileInfo fi_pdfDoc;
System.IO.FileStream fs;
str Content;
new InteropPermission(InteropKind::ClrInterop).assert();
fi_pdfDoc = new System.IO.FileInfo(@'C:/test.pdf');
pdfDocBuffer= new System.Byte[int642int(fi_pdfDoc.get_Length())]();
fs= new System.IO.FileStream(fi_pdfDoc.get_FullName(), System.IO.FileMode::Open, System.IO.FileAccess::Read);
fs.Read(pdfDocBuffer, 0, pdfDocBuffer.get_Length());
Content = System.Convert::ToBase64String(pdfDocBuffer, 0, pdfDocBuffer.get_Length());
CodeAccessPermission::revertAssert();

    I think that including hundreds of kilobytes of data in the business event goes against the idea of business events. They are supposed to be lightweight and provide minimal information, not be used for data integration purposes.

    I would not recommend implementing a solution that goes against Microsoft's guidance, even if it's technically possible.

    Thanks Blue Wang and Nikalaos

    @Nikalaos - The Size of the PDF File will be within 600KB. I dont think this will be an issue till the file size is small/within this range. Onthe other hand data transfer will take place in JSON file format which is again additional benefit.

    Do you have any other idea of handling this requirement?

    600kb is a lot for a business event, which are normally a few kb.

    I would recommend sending only key info in business event and fetching the PDF via custom service or data entity. If you read the MS article, that seems like the recommended way.
