Can someone help me in creting a start routine..

1. Read the table T006B

2. Map the Commm structure UOM field to T006b's MSEH3 field.

3. if they matches then COMM structure field will be passed into ODS field.

4. If NOT I need to match it with T006B's MSEHI field and find the correspoding value of MSEH3 and pass that value..
