ABAP MODIFY ITAB TABLE KEY Statement syntax, information and example SAP source code

MODIFY itab - table_key

Short Reference

ABAP Syntax ... TABLE itab [USING KEY
keyname ] ... .

The same applies when searching for a row to be modified as to key access using the statement READ .
If the primary table key is used to access a standard table and the key is
empty , then the first row of the internal table is deleted. If this is statically identifiable, the syntax check produces a warning.
Latest notes: When using the primary table key, note that this key can be the standard key , which can also have unexpected consequences:
For structured row types, the standard key covers all character-like and byte-like components.
The standard key of a standard table can be
empty .

Example ABAP Coding Converts the local currency of an airline using primary key access to the internal table scarr_tab .
