ARTICLE
Internal Tables - keyname> The name of the table key> can be specified in several statements and in table expressions for the editing of internal tables. The table key name can used to access a table row or to control processing. The following syntax applies to the label keyname>:
Syntax ... key_name | (name) ...>
Effect The name of a table key can either be specified directly, as key_name>, or dynamically, as the contents of a parenthesized character-like data object name> (not case-sensitive). You can specify:
a secondary table key> using its name
the primary table key> using its predefined name primary_key>
the primary table key> using an alias
the table key used in a LOOP>>-loop using its predefined name loop_key>. In this case, the statement must be executed within the loop.
Notes
Normally secondary table keys are specified. Only if searches> are to be performed explicitly in a table expression> using the primary table key does the key need be specified using its predefined name primary_key> or an alias name.
When specifying the primary table key using primary_key>, it is important to note that it may be empty> for standard tables. This can produce unexpected behavior in statements where the key is used to specify the rows to be processed.
