BI Publisher Add-In does not show up in Office 2010/Windows 7

If you are installing BI Publisher for the first time in your Laptop .If you have a Windows 7 (64 bit) Laptop and if your MS office is a 32 bit version, you will face this issue.

Where can i see my office version


The XML Publisher installation will be smooth, but if you open the MS Word you will not see the Add in Option in the tool bar.


Because you are installing a software that’s compatible on a 32 bit version on a 64 bit machine, Microsoft makes this Add in as an Inactive Add in

Open MS Word.go to File–> Options – Word options box opens and in that go to Add Ins


Under the Inactive application Add on you will see “BI Publisher Template for Word” as a COM Add in. In the above screen shot it shows active because i have fixed the issue

If you go to Manage: COM Add in at the bottom and try to enable this Add in, because its considered malicious Microsoft is going to make it Inactive again.


The only way out is You need to install “Visual Studio 2010 Tools for Office Run time” from Microsoft site, its a free executable.  Visual Studio 2010 download link The moment you install this “BI Publisher Template for Word” will become an active Add on and then bing!, you will see the BI Publisher Add in show up once you restart your word.


Caution: Close all MS Office related stuff during this installation process .

How to preserve Leading zeros in XML Publisher Excel Ouputs

In XML Pub Excel Reports excel removes the leading Zeros and prints the whole number. There are many instances where we need to print the zeros for eg item numbers starting with 0.

There are many ways to achieve this, one of the simple ways is to convert the number to character by adding space at the end.

concatenate two spaces after the xml tag as shown below in your template.

<?concat(<XMLTag>,’  ‘)?>

Downside of it is you will not be able to use excel features like sum , count etc on this specific column.

How to generate Session Trace from Toad or SQL Plus

alter session set max_dump_file_size = 50000000;

alter session set sql_trace = true;

Run your SQL’s
alter session set sql_trace = false;

select vpar.value || ‘/’ || instance || ‘_ora_’ || ltrim(to_char(vp.spid,’fm99999′)) || ‘.trc’
from v$process vp, v$session vs, v$parameter vpar, v$thread vthr
where vp.addr = vs.paddr
and vs.audsid = userenv(‘sessionid’)
and = ‘user_dump_dest’
Once you have the trc file use the standard tkprof procedure to get the tkp / tkprof file
