Infotype Characteristics

Infotype characteristics are determined by entries stored in various tables.

Tables that are maintained for all infotypes

Name of table	Task
T582A	Basic infotype characteristics (single screen, list screen, time constraint, and so on)
T582S	Infotype short texts
T777A	Technical characteristics of Infotype (database table, dialog module, and so on)
T77ID	Name of data field structure (PSnnnn)

You can maintain tables T582A and T582S in view V_T582A. Tables T777D and T77ID are maintained automatically when the Create Infotype transaction (PM01) is used.

Additional tables that are maintained for some infotypes

Name of table	Task
T591A	Table T591A is used if the infotype is divided into subtypes. The subtype characteristics are determined in this table. You can use a different table instead of table T591A. The table used to store the subtype characteristics must be specified in table T582A as the subtype table.
T588G	Table T588G controls field-specific retroactive accounting.
T588M	Table T588M enables you to adapt infotype interfaces using screen control . (You can specify an alternative or subsequent screen; user-specific screen control is also possible).
T588B	Infotype menus
T588Z	Dynamic actions

The entries stored in these tables must be maintained manually. You can use transaction PM01 Create Infotype to maintain basic infotype characteristics and set up infotype menus.
