SAP Business Application Programming Interface (BAPI)
SAP GUI Patches / Hotfixes
Regular maintenance tasks or the standard procedures must be described and defined to build checklists based on them and to control compliance with this standard. The SAPSolution-Manager can also support this as a tool of SAP e.g. through the Guided Procedures. In this context, it is also necessary to document the functionality of an underlying application and thereby determine what testing and monitoring activities are necessary. This is a reconciliation process between the SAP basis, other IT departments and, if necessary, the business areas concerned. The defined standard and the system's IST situation must be fully documented and regularly checked for compliance. This can be done through automated monitoring, validation using tools such as SAP-LVM (Landscape Virtualisation Management) or SAP Solution Manager, as well as manual checklists. Only the regular review of the standards guarantees their compliance. It can also support the regular use of SAP services such as Go-live Checks or Early Watch. Examples of how to standardise procedures are listed here: ・ Naming of system instances and logical hosts, or at least one central registry in a directory service, or LVM or SAP customer portal ・ Centrally starting and stopping systems, such as via the LVM ・ Categorising SAP instances by T-shirt size to define profile standards and cost them.
Therefore, there can also be critical permissions, profiles, and roles that do not fit in the naming scheme defined by SAP. Manual identification of critical SAP permissions is difficult overall. However, tools are available that automatically check for critical permissions. In this case, the critical SAP permissions are usually predefined by special verification software. If the critical permissions, profiles, and roles are identified, they should be adjusted according to the permission planning. The system will then be checked to see if the desired system behaviour has been achieved or if malfunctions occur. This adjustment process may be complex in the event of major changes and should not be carried out on the production system.
Finally run SQL queries directly in the SAP system
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.

The freeware Scribble Papers puts an end to the confusing paper chaos. The tool is also suitable for storing, structuring and quickly finding text documents and text snippets of all kinds in addition to notes.
This point may sound a little trivial at first. Who tests, surely documents this? Experience shows: Yes, but often patchy. In the case of unsuccessful tests, where subsequent or additional developments are due and the cause of the error is not directly apparent at first glance, good result documentation often pays off. This saves developers time in communication and effort by re-imagining the scenario. At this point, the SAP Solution Manager offers extensive opportunities to manage templates and result documents centrally and in the individual test plans. Automated testing only Automated testing offers many advantages, whether it is a higher software quality through more comprehensive test coverage or reusability of test cases. However, it does not always make sense to use only automated test scripts. A less good choice is the test automation for frequently changing software or processes, because the maintenance effort can be enormous. At this point, it is often more effective to run manual test runs instead of spending a lot of time customising test scripts. Poor test preparation The relevant processes have been defined, the test plans have been created and the test period has begun - so can testing begin? Not always. Lack of test preparation often leads to unplanned additional time costs. Sometimes the testers were not familiar with the test environment or no one thought about taking care of a sufficient and current test data set (master data, movement data). Make sure you have thought of everything you need! (missing test data, unrepresentative test environment, unstable).
For administrators, a useful product - "Shortcut for SAP Systems" - is available in the SAP basis area.
The alias of BASIS is SAP Application Server Technology and the alias of NetWeaver is SAP Web Application Server.
