On my current project I got the opportunity to work on Accenture DCM tool. For those of you who have never heard of this tool must be asking, what is that ?
It's a data comparison tool, it helps in comparing your SAP data that was recently migrated against your legacy data. There are two sides to this tool. The left side and the right side. The left side is the SAP side and the right side is the legacy side. On the left side you select the SAP fields for a given infotype that you want to do a compare. On the right side you select the legacy fields that matches the SAP field an example would be PERNR in SAP will link to Employee Number in Legacy.
You can write rules using IF statement. When the comparison is done, you will see the results in comparison like SAP Personnel Area and Legacy Personnel Area. if the values are the same then you will get a pass in the far right column, if not you will get a fail.
Very helpful for payroll comparison.
