Change File Name in SSRS

SSRS Report File Name.
There are two options for subscription on the SSRS one for email and one for file share, on the file share you can customize the name of the file, but the physical excel file need to be save on the system, this file will not be automatically emailed to the user. To do this you need to create SSIS job to email the file.

On the other hand the email subscription option does not provide the option to customize the name of the file for eg excel file.

Conclusion
We need to split the report into number of subscriptions needed or use the file share option and create SSIS job to email them.
