0 - 1 of 1 tags for Mload - 2797

Hello All,
I am running a mload job. In the source file, the fields are having different data types like Decimal, Char & Varchar. But when i am running the job, major volume of records are going to error tables with error code 2797 (saying MLoad MARK MISSING UPDATE). That means its not finding records with given where conditions.
