Through a sound expertise in the SAP technology environment, it is recommended to bring the know-how of the SAP basis into the IT strategy and IT roadmap. For this, the responsibility lies primarily with the CIO as the carrier and responsible of the IT strategy and the IT organisation. Likewise, the SAP basis should serve as a sparring partner for individuals and boards (such as enterprise architects) that significantly influence the strategy.

Today, "SAP Basis" often does not mean (only) the software architecture. Instead, the term is not infrequently a task description. This refers to the basic administration of the system: installation and configuration, resource management, maintenance and monitoring of a company's SAP setups. This can include user management, patch management and system monitoring. Backup policy, rights management and daily maintenance tasks are also responsibilities of Basis admins.
The SAP Patch Manager (SPAM) is the online correction support (OCS) customer site. The SPAM transaction gives you the ability to easily and efficiently import support packages provided by SAP into your system. Depending on the system used or the configuration of your system, you must insert different types of Support Packages [page 8]. You will receive support packages in SAPNet - Web Frontend, in SAPNet - R/3 Frontend or on Collection CDs. Since SPAM runs within the SAP system, you do not need to know the operating system to handle the transaction. In the language usage of SAP, the term patch has been replaced by the term support package. Note that you can only work with this transaction in SAP GUI for Java and SAP GUI for Windows.

In order to make a transaction in cryptocurrencies, you do not have to let your bank know about it as you would for "normal" money, but you have to use the Private Key to prove that you own the coins. The transaction looks like a piece of the puzzle. Half of the puzzle piece consists of information about the coin set, time and public address of the sender or receiver. The other half is the signature of the private key belonging to the sent public address. Both halves make this piece unique. Changing only one piece of information would completely change the whole transaction or the appearance of the puzzle piece. This transaction is transferred to the network or to the miner and is checked for correctness first. If everything fits, the transaction will be sent to other miners who will do the same. Otherwise, the transaction is ignored. Miners try to integrate the transactions into a block. This is called mining and we have described it so that the miners put the puzzle pieces together into a puzzle (block). A small part of a block to be integrated follows from the block that was previously mined. If all miners accept the correctness of a completed block, they will all work the next one immediately. The puzzle (block) is fixed and is irrevocably connected to the block before or after. The blocks form a chain and are called blockchain, which contains all the transactions that have ever been made and is visible and unchangeable by everyone. In doing so, blockchain replaces a central institution and avoids double-spending, which ultimately gives value to a cryptocurrency. Smart Contracts The biggest advance compared to Bitcoin and similar applications is that second-generation blockchains, such as Ethereum, use the so-called Turing-Complete script language Solidity. This enables calculations to be made within the blockchain. While Bitcoin allows only rudimentary multi-signature functions, Ethereum opens the door to much more complex operations called smart contracts. Smart contracts are contracts in which a decentralised blockchain ensures their unchangeability and execution.

Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.

An SAP administrator is responsible for controlling the SAP system in a company and ensuring its trouble-free operation.

Note that a change only takes effect when the instance is restarted!
