Support for adjustments and changes to the systems
A first important step was the introduction of playbooks to professionalize our work. Back then, SAP installation manuals were real tomes with hundreds of pages that often went around in circles and were anything but easy to understand....
In addition to the database, the SAP system itself is installed. This installation is planned using a tool from SAP, the "Maintenance Planner", and then carried out using the SWPM (Software Provisioning Manager) and SUM (Software Update Manager) tools.
What is an SAP transport request? How to import/export TR?
If you want to skip the backgrounds and prefer a direct step-by-step guide, you can jump directly into the last section. Preparation For this workaround, you need access to both the source system and the BW system. In addition, they shall have the possibility to access the SE37 and execute functional modules there. Especially in production systems this is a very critical justification. So assume that you may need a Firefighter user for this action. Working in the BW system Now that the preparations have been completed, you have to call a FuBa on the BW system and on the source system, which solves the connection on the respective page. Beginning on the BW system, go into the transaction SE37 and call the function block "RSAR_LOGICAL_SYSTEM_DELETE": RSAR_LOGICAL_SYSTEM_DELETE Enter the required values here. The following table helps you fill in: Field Description I_LOGSYS The logical name of the source system. The name of the source system, as found in RSA1, will be entered here. In addition, this name can also be found in the DB table TBDLT. I_FORCE_DELETE Boolean, X = Delete despite error messages I_NO_TRANSPORT Boolean, X = This change should not be transported to subsequent systems I_NO_AUTHORITY Boolean, X = Ignore Permission Checks Work in the source system In the source system, go to transaction SE37 and call the function block "RSAP_BIW_DISCONNECT" : The descriptions of the fields are as follows. These can be found in the RSBASIDOC source system connection table Field Description I_BIW_LOGSYS The logical name of the BW system. In the RSBASIDOC table, find the correct value in the column "RLOGSYS". I_OLTP_LOGSYS The logical name of the source system. The column ‘SLOGSYS’ in the table RSBASIDOC. I_FORCE_DELETE The logical name of the BW system. In the RSBASIDOC table, find the correct value in the column "RLOGSYS". Completion In the end, you have to call the respective function block in the BW and source system, fill in the parameters and execute the function block.
In the past, when we deployed SAP environments, we first had to work out a detailed sizing and architecture and pass it on to the procurement team, which then ordered the systems and installed them in the data center. From there, it went on to the network team, the storage team, the operating system team, and the database team. So it was not uncommon for three to six months to pass between the architecture design and the installation of a new SAP system.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
Before the project starts, it must be clear which systems are to be connected to the IdM and which services the system is to provide.
The transaction SPDD matches Dictionary objects, and the transaction SPAU Repository objects.
