 - There are even further dynamic programming techniques in the unrestricted language scope like the
 generation or execution of programs at runtime. They are not part of this cheat sheet. Find more details on the related syntax (e. g. `GENERATE SUBROUTINE POOL`, `READ REPORT` and `INSERT REPORT` in the ABAP Keyword Documentation for Standard ABAP: [Dynamic Program Development (F1 docu for standard ABAP)](https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abenabap_language_dynamic.htm)
