MONIENVSD 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 "SD Monitor: Analysis Area SD Specific" 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_MONIENVSD TYPE MONIENVSD.
The MONIENVSD table consists of various fields, each holding specific information or linking keys about SD Monitor: Analysis Area SD Specific data available in SAP. These include MANDT_DIFF (SD Monitor: Different clients for analysis and protocol), VBELN (Sales and Distribution Document Number), PAPPL (SD Monitor: SD Log Initiator), PAPPLMAINT (SD Monitor: The log application is supported by the analysis)...
