• Key Concepts: 
  A database procedure proxy is a feature of the ABAP Runtime Environment (BC-ABA) in SAP that allows for the execution of database procedures from within an ABAP program. It provides a way to access and execute database procedures stored in the database without having to write any additional code. 
  
  How to use it: 
  Database procedure proxies can be used in ABAP programs by calling the function module ‘DBPROC_PROXY_CALL’. This function module takes the name of the database procedure as an input parameter and executes it. The output of the database procedure can then be accessed via the output parameters of the function module. 
  
  Tips & Tricks: 
  When using database procedure proxies, it is important to ensure that all input parameters are correctly specified and that all output parameters are correctly handled. It is also important to ensure that the database procedure is properly secured, as it will be executed with the same privileges as the user who is executing the ABAP program.
