How to reduce the number of entries of table SOFFCONT1?
- The document is not stored using the Knowledge Provider (KPRO).
- The document is stored using the knowledge provider.
- Which document types are stored using the KPRO?
- all documents that are transferred to a SAPoffice interface in binary form,
- external documents (type EXT), providing that they are not text documents
- OTF documents.
- ALI documents.
- Can I determine whether a document is stored in the KPRO?
- (Information for technical support)
- Report RSIRPIRL relocates all objects from SOFFCONT1 to a content server.
- Report RSGOS_RELOCATE_ATTA does NOT replace report RSIRPIRL.
- Regarding how to use report RSIRPIRL.

Artificial Intelligence in SAP Solutions
Artificial Intelligence adoption continues growing
The ability to think and learn in humans is called natural intelligence, therefore in machines, we call it artificial intelligence (AI). There are two primary types of AI: traditional and generative. Traditional AI can recognize patterns, but generative AI creates new patterns based on the recognized historical patterns and any additional data that's provided. Machine learning is a subset of AI, focused on teaching computers to learn from data and improve with experience, instead of being explicitly programmed to do so. In machine learning, algorithms are trained to find patterns and correlations in large data sets, and to make the best decisions and predictions based on these analyses. Machine learning applications improve with use and become more accurate the more data they have access to.

Getting Logon pop-up in transaction CSADMIN - SAP Content Server 750 and higher
Getting Logon pop-up in transaction CSADMIN - SAP Content Server 750 and higher:
When accessing transaction CSADMIN through transaction OAC0, a logon pop-up comes up:
- When installing SAP Content Server 750, uncheck the 'Enable AdminSecurity' box in the Software Provisioning Manager.
- AdminSecurity is now controlled by parameter icm/HTTP/auth_0.To disable this authentication, edit the SAP Content Server profile on path /usr/sap/<SID>/SYS/profile/<SID>_C<Ins.no)_<hostname>.

List of key SAP Memory parameters
List of key SAP Memory parameters:
• PHYS MEMSIZE: Specifies the size of the main memory of the host on which AS ABAP is running .
• em/initial size_MB: Specifies the total size of the extended memory (EM). The value is derived from the size of the physical main memory.
• EM/TOTAL SIZE MB: Controls the total size of the EM for the implementation of
shared memory segments (SHM segments).
• em/max size MB: Specifies the maximum size of the dynamically extendable EM
• em/global_area_MB: Specifies the size of the global extended memory (EG)
• abap/heap_area_dia: This value specifies how much PRIV memory can be allocated for a user context by a single dialog work process. The aim is to limit the maximum size of user contexts so that one single user cannot occupy the entire memory available.
• abap/heap area_nondia: Specifies how much PRIV memory, a non-dialog work process(background, update, the system and print processes) can allocate for a user context. The aim is to limit the maximum size of user contexts so that one single user cannot occupy the entire memory available.
• abap/heap_area_total: Specifies how much PRIV memory dialog and non-dialog work processes can allocate for user contexts.
• abap/heaplimit: This value specifies the amount of PRIV memory that, if exceeded,automatically restarts a work process after completion of the current transaction step. A bottleneck in the swap space should be prevented by using an automatic restart (as seldom as possible).
• em/proc_max_size MB: Specifies the maximum amount of PROC memory all work processes together can use. The value 0 means that there is no limit to the PROC memory
• rdisp/wppriv_max no: The value specifies the maximum number of work processes that are allowed to be in PRIV mode.
• rdisp/max priv time: This parameter value specifies the maximum time spent by a work process in PRIV mode.
• ztta/roll_extension: Specifies how much EM can be assigned to a user session (usercontext). The EM quota applies both to dialog work processes and to non-dialog work processes. The current parameter value is the default value for ztta/roll_extension_dia and ztta/roll_extension nondia. ztta/roll_extension only takes effect if its value is lower than em/initial size MB.

SAP Shared Memory (SHM)
SAP Shared Memory (SHM):
SAP shared memory is a shared memory resource in SAP Memory Management in which various buffer data are stored. SAP SHM provides a shared memory that is shared by all work processes. It is based directly on the shared memory of the operating system. It comprises SAP SHM segments that are divided into local and global segments.
Local SAP SHM segments can be used by all work processes of one application server instance (AS instance). Global SAP SHM segments can be used by all work processes of all AS instances running on the same host The size of the shared memory pools is defined in the parameter ipc/shm_psize_<xxx>. The parameter is valid on all operating systems. However, the creation of the pools is heavily dependent on the operating system.
