usage of check mode algorithm for Checking Data Consistency

hi Team,

we are getting errors in heuristic run how can we utilise the check mode algorithm to perform a number of checks for master data and key figures.

The check mode algorithm does not change any data, but it returns messages for violations detected by the checks.

1.Node-based (master-data-based) cycle check

2.Heuristic-based cycle check

3.Key figure plausibility checks (with regards to master data)

Can you list down steps for above checks .

regards

sanket.
