0recordmode is missing

Hi All

While Iam activating update rules from infosource,its saying like 0recordmode is missing.

Iam updating data from Flatfile.

What is this 0recordmode?Why v need it?and where to declare this object in an ods object(either in Keyfields or data fields)

Should v need to create this or install this business content.should v give data from this(orecordcode)in flatfile.

PL LET ME IN THIS REGARD.

Regards
