Error:The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION.


The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION.
The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION.

Here is the sp that caused the error

drop procedure [dbo].[PROC_ARCHIVE_EOM]

Added @@tranCount check to avoid this error
