Cannot resolve the collation confict

Hi All,

Not sure why I am getting this error whenever I execute the Staging Stored Procedure.

Msg 468, Level 16, State 9, Procedure udp_Geography003_Continent_Leaf, Line 989
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS" in the equal to operation.

Code:

DECLARE @BatchTag AS NVarChar(50)
DECLARE @Version AS NVarChar(50)
DECLARE @LogID AS Int

SET @BatchTag = 'MDSCountryInsert'
SET @Version = 'VERSION_1'
SET @LogID = 0

EXEC stg.udp_Geography003_Continent_Leaf @Version, @LogID, @BatchTag 

I know what the error means, it just that I don't get it why this error came up. It seems the sp is just using the same database.

Cheers,
