MODIFY itab - table_key

Short Reference

Other versions: 7.31 | 7.40 | 7.54

Syntax


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

Effect

For wa, a work area compatible to the row type of the internal table must be specified. This concerns functional operand positions. The first row of the internal table found, whose values in the columns of the table key used match those of the corresponding components of wa, is processed. If the key fields in wa are empty, no entries are processed.

If the USING KEY addition is not specified, the primary table key is used. If the USING KEY addition is specified, the table key specified in keyname is used.

When searching for the row to be modified, the same rules apply as for key access using statement READ.

If a standard table is accessed using the primary table key and this is empty, the first row of the internal table is modified.


Note

If the primary table key is used, note that this can also be the standard key, whereby unexpected effects may occur:

  • For structured row types, the standard key encompasses all character and byte-like components.
  • The standard key of a standard table can be empty.


Example

Conversion of the local currency of an airline by means of primary key access to internal table scarr_tab.

PARAMETERS p_carrid TYPE scarr-carrid. 

DATA scarr_tab TYPE SORTED TABLE OF scarr 
              WITH UNIQUE KEY carrid. 

DATA scarr_wa TYPE scarr. 

SELECT * 
       FROM scarr 
       INTO TABLE scarr_tab. 

READ TABLE scarr_tab INTO scarr_wa 
     WITH TABLE KEY carrid = p_carrid. 

scarr_wa-currcode = 'EUR'. 

MODIFY TABLE scarr_tab FROM scarr_wa 
       TRANSPORTING currcode.
