## ⚡ Known Issues
- Only one user on the system can import this repository because all object names must be globally unique. Before importing the code, you should perform a system-wide search for classes named *ZCL_DEMO_ABAP**, for example. If someone has already imported the content into the system, you can simply check out that imported code.
- Regarding possible code check warnings, e.g. for the many strings in the code, not using an `ORDER BY` clause, or messages regarding using `SELECT *`, the code deliberately avoids [pragmas](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenpragma_glosry.htm) and [pseudo comments](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenpseudo_comment_glosry.htm) in order to focus on the available ABAP syntax. See also the [Disclaimer](#%EF%B8%8F-disclaimer).
- Regarding the examples to be imported into on-premise ABAP systems, note the following: The cheat sheet documents cover ABAP syntax regardless of the ABAP release to avoid scattering information and to have the information in one place. Therefore, the lower the release, the fewer syntax options and examples are available. For example, the RAP examples in particular require at least ABAP version 7.56.

The code examples in the classic ABAP branches do not necessarily reflect all (described) syntax variations and options that are available in classic ABAP and in the particular ABAP release.
