Trying to change the data source for a Crystal Report.

Question

<p>The method below represents my best attempt to programatically change the data source of a Crystal Report. The goal is to have a routine that will update the data source for reports after they have been distributed to production servers. So far I have not been successful in saving the report back to the CMS. No exceptions are thrown, but when I view the Database Configuration of the report in the CMC nothing has changed.
</p>
<p>
Am I missing a step, or is there another way to accomplish this?
</p>
<p>
Thank you.

<p>Justin,</p>

Thank you for the reply. Time constraints have not allowed me to post back to this tread
till now. I will try your suggestion. My assumption is that <i>Save the report back to the
info store</i> refers to <span class="code">IInfoStore.commit(IInfoObjects)</span>.
</p>
<p>
I'm afraid that I do not understand why I don't want to change the report client document,
or why <i>successfully exporting the report with the new login/password</i> is not what I
want to do. Any explanation on that statement would be appreciated.
</p>
<p>
I did find a way to accomplish my goal. It involved adding the SSOKEY property to the
logon property bag. Below you'll see my revised code which modifies the report logon and
server. I have no idea what
this does, and SAP support has not been able to tell me why it works. However, what I
discovered is that if I changed the report option, <b>Database Configuration -> When
viewing report:</b>, in the CMS to <span class="bi">Use same database logon as when report
is run</span> from <span class="bi">Prompt the user for database logon</span>, then the
SSOKEY property had been added to the logon property bag having an empty string as its
value. This allowed me to successfullyupdate and save the modified logon back to the CMS.
</p>
<p>
So I took a chance and added code to always add the SSOKEY property with an empty string
as its value, and I could then successfully modify and save the report's logon info
and server. Again, I don't know what this means, but it has worked so far. If anyone has
some insight or comments, either are welcome. Thank you in advance.
