Dear Sir,
Many Thanks for the interesting project task :-)
Yes I can trigger any SSRS subscription using schedule times store on table.
1. We need to have SSRS subscription
2. schedule timing stored on table as required
3. SQL procedure to trigger the ssrs subscription according to the table data OR SSIS package for calling SSRS subscription as required
SSIS is the best option for your requirement . using SQL SP also can complete your task
Please let me know more details. I can compete this task now
Best Regards,
Jinesh
