'Blob' is not a valid variable type in AL Report

Posted on by Hein Kruger 629

I need to create a Global Variable of type blob for a report but I'm getting this error --'Blob' is not a valid variable type--
After searching a bit I found people referenced the "Temp Blob" codeunit and I managed to import into the temp blob code unit using FromRecord().

My Question is. How do I reference the blob in temp blob as a field in the report?
Is there another way to create and use Blob variables in reports?

I have the same question (0)

    What’s the intention for the blob? If you look at the base app you have blob/media fields in tables. The contents of the blob/media is then drawn into the report. Like the company logo image

    I'm using the blob in my warehouse Lines to capture a signature. The problem is when there is no signature captured the report gives an error.

    The blob field is stored in the SetData on the report because the signature is used in the footer. My idea on AL side was to create a global blob field that will populate the company logo when the field is blank and it will hide the image by making use of a boolean on the report.
