Troubleshooting and support in case of occurring problems
USING STANDARDISATION AS A BASIS FOR OUTSOURCING
If you need to reinstall a Support Package because of errors or because a SPAM update is required, reset its status. Resetting does not mean that the system is at an old state. Note that your system is inconsistent when you reset the status after items have already been imported (for example, after the DDIC_IMPORT step and following). Resetting the status should only be used to troubleshoot the issue and you should repeat the playback as soon as possible. Procedure To reset the status of a Support Package or Queue, select Add Status Reset. Result After updating the status, the corresponding entries in the cofile and in the log file are deleted. The support package must then be fully reloaded. The transaction SPAM starts the insertion with the step CHECK_REQUIREMENTS [page 26].

An important area of SAP Security is the analysis of the customer's own SAP programs, which are classically written in the proprietary SAP language ABAP. Here, too, as in all programming languages, security vulnerabilities can be programmed - whether consciously or unconsciously. However, the patterns of security vulnerabilities in ABAP code differ from those in Java stacks or Windows programs. The goal of these conventional programs is usually to either crash the program (buffer overflow) or to artificially execute the program's own code (code injection). Both is not possible in ABAP, since a crash of a process causes nothing else than the creation of an entry in the log database (Dump ST22) and a subsequent termination of the report with return to the menu starting point. So a direct manipulation as in other high level languages or servers is not possible. However, there are other manipulation possibilities.

How does a blockchain build consensus? Once you decide to send a payment to someone, you must use the Private Key to "sign" it (in German: signature). This means nothing other than that you specify another public address to which you want to send the money and confirm this transaction with your own private key. You don't have a central authority to send the information to, you're going to spread the information to all the other Miners around you. The miners then forward this information to other miners, who in turn do the same. This exponential wave of information reaches the entire network of the distributed community within a few milliseconds. Every time a miner receives a transaction, it checks that the transaction is actually correct. It checks which private key has signed, which public address the transaction should go to and whether the sender has enough "coins" for this transaction. What are consensus mechanisms? Any miner that solves a transaction through complex mathematical calculations is rewarded by the sender with a "fee" (transaction fee). How will it be decided which miner will receive the transaction fee? Because only one can get this reward. Also, what happens when you try a double spending by sending one transaction to one miner and then another transaction with the same money to another one millisecond later? These two could not yet exchange and thus information would be different in the network.
