Point Source

Hi all,

I've created a new Point source "O' in the Point source table @ SMT Plugin then i created tag with the Point source "O"  in the point builder, but i cannot able to save / create the tags it's shows an error message in the Session record as "PI-PB> Error -2147220428 attempting to write point reer on server HISTORIAN: Failed to create point on server.  [-12234] Disallowed Point Source(pointtype) (SDKWritePoint)".

Can anyone help me out how to overcome this error and to create the tag my own Point source? How to delete the created Point source?

Thank you in advance
