Workflow-Attaching pdf from Custom Concurrent Request to email notification

Question

Hi,
I was wondering if anyone has done something similar before and maybe have any suggestions?
I am trying to attach a .pdf file that is generated by a custom concurrent request report to an email notification.
The .pdf is generated correctly and I can access the file but I’m having problems trying to attach it to the email notification
I have tried to use Wf_Engine.SetItemAttrText and Wf_Engine.SetItemAttrDocument but are unable to get it to attach the file.
Does anyone know where I can find an example how to use either of the above API's? and a detailed explanation of them?
Should the attachment always be in FND_LOBS to be picked up or can it be picked up from the file system?
What should the Workflow - Notification - Performer Value be set to, that is referencing the message with the Document Attribute?
I'm unable to find a detailed explanation of how this can be done in the Oracle Workflow Developers Guide Release 2.6.4.
Any reference material or guidance as to where an example can be found will be greatly appreciated
Thanks
Coenraad

The PLSQL procedure that generates the PL/SQL BLOB documents must follow standard API formats and a sample is shown below.
procedure GENERATE_PDF(document_id in varchar2,
content_type in varchar2,
document in out nocopy blob,
document_type in out nocopy varchar2)
is
l_docid pls_integer;
l_filename varchar2(100);
l_errmsg varchar2(100) := 'The Document is not found in the Database';
l_bdoc blob;
l_data_type varchar2(100);
begin
l_docid := to_number(document_id);
dbms_lob.CreateTemporary(l_bdoc, FALSE, DBMS_LOB.Session);
SELECT file_data
into l_bdoc
FROM fnd_lobs
WHERE file_id= l_docid;
dbms_lob.Copy(document, l_bdoc, dbms_lob.getLength(l_bdoc));
exception
when others then
dbms_lob.WriteAppend(document, length(l_errmsg), l_errmsg);
wf_core.context('SA_MLRTST','GENERATE_PDF',document_id);
raise;
end GENERATE_PDF;
You can use FND_LOBS or any other table to get the content. The content must be stored into the corresponding table before using it.
The following is the PLSQL script for generating BINARY data for a file
declare
l_bfile BFILE;
l_temp_blob blob;
l_docid number :='1000';
l_ctype varchar2(300) :='application/pdf';
l_filename varchar2(50) :='testfile.pdf';
begin
dbms_lob.createtemporary(l_temp_blob, true, dbms_lob.session);
l_bfile := BFILENAME('OEX_INPATH',l_filename);
dbms_lob.fileopen(l_bfile, dbms_lob.file_readonly);
dbms_lob.loadfromfile(l_temp_blob, l_bfile, dbms_lob.getlength(l_bfile));
INSERT INTO fnd_lobs(file_id, file_name, file_content_type,file_data,file_format)
VALUES( l_docid,l_filename,l_ctype,l_temp_blob,'binary');
end;
OEX_INPATH - this is a database directory, you need to copy the pdf file which you want to convert to BINARY to the location which this directory points
l_filename - name of the file which need to be converted to BINARY format
