Deleting Adjacent Duplicate Entries
To delete adjacent duplicate entries use the following statement:
DELETE ADJACENT DUPLICATE ENTRIES FROM itab
COMPARING f1 f2 ... .
The system deletes all adjacent duplicate entries from the internal table itab. Entries are duplicate if they fulfill one of the following compare criteria:
·        Without the COMPARINGaddition, the contents of the key fields of the table must be identical in both lines.
·        If you use the addition COMPARING f1 f2 ... the contents of the specified fields f1 f2 ... must be identical in both lines. You can also specify the fields f1 f2… dynamically using (n1) (n2) … as the contents of a field n1 n2. If n1 n2 is empty when the statement is executed, it is ignored. You can also restrict all fields f1 f2 … to subfields by specifying offset and length.
·        If you use the addition COMPARING ALL FIELDS the contents of all fields of both lines must be identical.
You can use this statement to delete all duplicate entries from an internal table if the table is sorted by the specified compare criterion.
hope this helps.
