DELETE itab

Short Reference

Syntax

DELETE { itab_line |itab_lines |duplicates }.

Effect

This statement either deletes one or more rows itab_lineor itab_linesspecified with a table key or a table index, or it deletes neighboring duplicate rows duplicates.

System Fields

sy-subrc	Meaning
0	At least one row was deleted.
4	No rows were deleted, since no appropriate row was found when deleting using a tablekey or in the logical condition, the index specified when deleting using a table index was larger than the current number of rows, or no duplicate neighboring rows were found.

Notes

• When deleting rows in an internal table, costs are incurred for updating all existingtable keys andtable indexes. Theprimary key and all uniquesecondarykeys are updated directly, whereas non-unique secondary keys are only updated if the rows to be deleted are contained within an updated part of a relevant index(lazy update). When deleting a row from a standard table using a secondary key, theprimary table index in particular must be updated, and this requires a linear search.
  
• There is no implicit selection of a suitable key or index. The used table key or table index is always specified uniquely. The syntax check issues a warning if there is a suitablesecondarytable key but this table key is not used. This warning should be removed through using the key. However, in exceptional cases, it can be bypassed using apragma.
