Reg : Webi Error

Hi Guys ,

When i tried to schedule the report and when it got run , then it show's following error :-

source file error. invalid argument crystalenterprise.diskunmanaged

This error occurred not all times , occurred only some time .

The report destination is Shared drive . There is no issue with Shared Drive , may be issue with some Business object Server.

It's very urgent report , so must be run successfully at specific time .

Can anyone give fix solution for this .

Appreciate your quick response .

Regards,

Lavneet
