Cognos: Bursting Report to a file system

Bursting cognos report to Local File system and also run a script so that bursted reports can be renamed.

1) Go to the dispatcher --  ( See the picture below for reference )

2) Click on the dispatcher link to see the content manager service.

 3) Go to the settings tab and click on edit on advance setting line -
4) Create following  2 variables and provide the path where you want to get the files bursted.
 5) Save it and go to cognos configuration to do the following setting.
 6) Run the report that you have to burst with the following settings.

7) You will get the output in D:/Report folder, now you want that bursted reports should get proper names or they should get names according to there bursted key.
8) Create a notepad file giving it a name "burstKey.bat" and paste the following contents and save it in D:\Reports folder.
@echo off
Rem  this batch file is launched with a working directory of \bin  

set dest=D:/Reports

echo "BurstKey Script" >> %dest%/batch.txt
echo Batch File Log >> %dest%/batch.txt

rem       Set the values for the PDF file and XML 
rem       to environment variables
rem       the reason for this is the scripting language
rem       cannot read variables as parameters
set parameter_pdf=%1%
set parameter_xml=%2%

rem      Logs the variables to a batch log file
echo values set >> %dest%/batch.txt
echo Parameter_pdf: %parameter_pdf% >> %dest%/batch.txt
echo Parameter_xml: %parameter_xml% >> %dest%/batch.txt

rem      Calls the script file 
call %dest%/burstKeyRename.vbs

echo Completed >> %dest%/batch.txt
9) create a file "burstKeyRename.vbs" and paste the following contenets in there and save it in D:\Reports folder.
