ABAP is therefore the tool of the trade for SAP developers. ABAP programs are executed on an SAP NetWeaver application server, which in turn is operated by SAP Basis employees.
The following list explains the steps in the order they are performed by SPAM: PROLOGUE This step will check if you are eligible to play Support Packages. CHECK_REQUIREMENTS In this step, different requirements for inserting are checked, e.g. the login of the transport control programme tp to your system. DISASSEMBLE In this step, the data files are unpacked from the corresponding EPS packages and placed in the transport directory. ADD_TO_BUFFER In this step, the queue is placed in the transport buffer of your system. TEST_IMPORT This step checks whether there are any objects that are overridden during the commit and are in unreleased tasks. IMPORT_OBJECT_LIST In this step, the object lists for the support packages that are in the queue are fed into the system. OBJECTS_LOCKED_? This step checks to see if there are any objects that are overwritten during the commit and that are in unreleased jobs. SCHEDULE_RDDIMPDP In this step the transport daemon (programme RDDIMPDP) is planned. ADDON_CONFLICTS_? This step checks to see if there are conflicts between objects in the queue and add-ons installed. SPDD_SPAU_CHECK This step will check if a modification match (transactions SPDD/SPAU) is necessary. DDIC_IMPORT In this step, all ABAP Dictionary objects of the queue are imported. AUTO_MOD_SPDD This step checks whether modifications to ABAP Dictionary objects can be adjusted automatically. RUN_SPDD_? This step prompts you to customise your modifications to ABAP Dictionary objects by calling the transaction SPDD. IMPORT_PROPER In this step, all repository objects and table entries are fed. Then actions such as distribution, implementation, activation and generation take place. AUTO_MOD_SPAU This step checks whether modifications can be adjusted automatically. RUN_SPAU_?

It is possible to specify a trace level for each rule in the ACL file to monitor each communication channel individually. It can be used with SNC without any further configuration. The use of the file is controlled by the gw/acl_file parameter by simply setting it to the appropriate file name. Use of external programmes If an external programme wants to communicate with your SAP system, it must first register at the gateway. The programmes which this is approved are controlled by the reginfo ACL file. This defines rules that allow or prohibit certain programmes. The syntax of the file allows you to define not only the name of the programme, but also the host on which the programme runs and hosts that can use and exit the programme. The gw/reg_info parameter must be set to use this file. In addition, there is the ACL file secinfo, which allows to configure which users can start an external programme. This defines rules that allow certain usernames from the SAP system to use certain external programmes. In addition, you can also define the hosts on which these programmes will run. For example, it is possible to allow a user to run the programme "BSP" on the host "XYZ", but not on the host "ABC". This file is controlled by the gw/sec_info parameter. Using the gateway as a proxy Since the gateway of your SAP system can also serve as a proxy server, the prxyinfo ACLDatei should also be activated via the gw/prxy_info parameter. Suppose you have 3 SAP systems in your network: SRC, TRG and PRX. If SRC cannot communicate directly with TRG, but both with PRX it would be possible to use the gateway of the PRX system as a proxy server, i.e. to communicate via it. So, in order to prevent this from happening to everyone, this property should be urgently restricted. As with the other ACL files, rules are defined which hosts can communicate with which hosts via the gateway. The syntax of the different ACL files may vary depending on the release level. It is therefore advisable to read them in the appropriate SAP documentation before activating the ACL files. You can also find more support for using ACL files in the SAP Community Wiki.
In order to reduce the complexity of the SAP basis operation and to accelerate and simplify the tasks of the SAPBasis and to create free capacities, standardisation and automation of the existing activities is required. Details can be found in chapters 7.7 and 9.5 of the Master's thesis.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
If a change of department does not automatically involve a complete reallocation of roles and the employee simply takes his old permissions with him, critical combinations of permissions can occur very quickly.

A possible cause of error is that the appropriate OCS file was not found or the data file could not be opened for writing.
