ACT01_TIME is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Fields from ACT01 with time ref.(for authztn check LDB PSJ)" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_ACT01_TIME TYPE ACT01_TIME.
The ACT01_TIME table consists of various fields, each holding specific information or linking keys about Fields from ACT01 with time ref.(for authztn check LDB PSJ) data available in SAP. These include ZMINU (Minimum overlap time), ZEIMB (Unit for the minimum processing time), ZMINB (Minimum processing time), ZEILM (Unit for the maximum wait time)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
