Data Driven Subscription with Dynamic Email Attachment File Name

Hello Guys,

I have report which accepts a card number and fromdate and todate as parameters to the report. This report needs to be sent on a quarterly basis to each of the customer mail id to which their card number is linked. I am getting all this information from a database and sending as an attachment to the customer. Now I would need some help in making these filename's which are attached to be dynamic based on the input parameters.

In datadriven subscriptions, the option of include report has only true or false values and another option was to take from a database. I tried putting the dynamic file name in the database and getting the value from the database but no success, the subscription itself is failing here. I guess I am doing something wrong here by binding the report name from the value which I am getting from DB to the actual report name.

If report name = Mytransactions, and the parameters passed are Card = 123,fromdate = 1/1/2010,todate = 31/3/2010.

Now in the attachment the file name should be something like "Mytransactions_123_January1st2010_March31st2010".

Let me know how to make the filename dynamic.
