Repository layer: These are standard Objects which are in the namespace A-X and not allowed to be modified by any user except developers.
These Objects are generally locked and requires a Key from SAP for Modification or Repair. There are 4 million Objects in the Current Version of ERP
Customer can develop their Objects in the namespace ‘y’ or ‘z’. The Customers can also have their own namespace registered with sap and develop in the namespaces /company/A to Z*
Cross Client Objects: These are table entries which are applicable to all the clients in the System ex: T000, TBDLS, TACT, and USR40

Client Specific Objects: These are table entries which are specific to the Client and applicable to that client only.
Ex: User Master, Material Master vendor, Customer etc.

Spool Process Work Flow: User Submits the request to print a Document. The Dialog Process handles the request and print directly or schedules to print in the background.The Print requests are stored in the TemSe(Temporary Sequential Files) Temporary Sequential Files are stored either at File System or at database Level which is defined by parameter rspo/store_location. rspo/store_location=”G” or ‘DB’ G means global directory stores the TEMSE in /usr/sap/SID/SYS/global db mean the Tables TST01 and TST03.(TST01 Contains Print Attributes and TST03 Contains the Spool Data to be Printed) Due to Spool in DB the DB Size Increases, as a Result, the backup time increases and Tapes may not fit with the data for S...

Enque Processes are configured by parameter rdisp/wp_no_enq=1. Generally One Enque Process for instance is sufficient,more then one is required in a massive update system. The Lock table size on the memory ranges between 4mb to 100 MB(200 MB in the Net weaver 7.3 Systems ) It is defined by parameter enque/table_size=4 to 200 MB. For 4mb of enqueue table size, the Number of lock/owners/objects/arguments can be restricted up to 3715. Enqueue Flow: User submits the Request for an Update.
