Setting Constraints for a Report Parameter

Hi Friends,

I have report which has a Parameter named Account. This Account is a Text Parameter. We can send multiple accounts seperated by Comma. I have a requirement which says that I cannot process more than 5 accounts. So I am looking if there is a way to check this in the Report Parameter.

As a work around, I am checking the no of account passed within the SP used in the Report and I throw an exception if the no of accounts is more than 5. But, I would like to know if we can check this in the Report Parameter itself.

Any help would be appreciated.

Thanks
