Problem sending .pdf with email in ECC 6.0

hi there,

we are upgrading from r/3 4.6.c to ECC 6.0.

i have the following problem: in many z-ababs we convert spool-files to pdf-files and send them with function SO_NEW_DOCUMENT_ATT_SEND_API1 via email.

well, this is working okay, BUT: the ending '.pdf' is missing in the filename:

in R/3 4.6.c it looks like the following:

zfl_reporting.pdf

Now it looks like this:

zfl_reporting

So the file is not recognized as pdf-file. You have to add a .pdf manually to open it.

We can't do this as we send the pdf-files thousands of times to our customers.

Any ideas ?

reg, Martin
