Hi,
To delete adjacent duplicate entries use the following statement:
DELETE ADJACENT DUPLICATE ENTRIES FROM <itab>
                                  [COMPARING <f1> <f 2> ...
                                             |ALL FIELDS].
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 COMPARING addition, the contents of the key fields of the table must be identical in both lines.
If you use the addition COMPARING <f1> <f 2> ... the contents of the specified fields <f 1 > <f 2 > ... must be identical in both lines. You can also specify a field <f i > dynamically as the contents of a field <n i > in the form (<n i >). If <n i > is empty when the statement is executed, it is ignored. You can restrict the search to partial fields 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.
If at least one line is deleted, the system sets SY-SUBRC to 0, otherwise to 4.
as per your requirement, while deleting duplicate records based on thrid field.
DELETE ADJACENT DUPLICATES FROM ITAB COMPARING COL3.
in the above statement ITAB( internal table) and COL3( third field).
