Hi Virendra,
Yes there is way to upload document in task and set the scope of accessing the same.
In SAG document “8-2-SP1_BPM_Task_Development_Help.pdf” there is a section “Working with Task Attachments” where it is described step by step to add this functionality to project property.
Please let us know if you are facing any issue for implementing the same.
Thanks
Baharul Islam
