GRRM_S_CACTIVITY_BUFFER 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 "Activity Data Buffer" 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_GRRM_S_CACTIVITY_BUFFER TYPE GRRM_S_CACTIVITY_BUFFER.
The GRRM_S_CACTIVITY_BUFFER table consists of various fields, each holding specific information or linking keys about Activity Data Buffer data available in SAP. These include CACTIVITY_ID (Object ID), PARENT_ID (Object ID), CACTIVITY_TITLE (Title/Short Name), ACTIVITY_TYPE_ID (Activity Type Id)...
