• What is the cause and solution for SAP error message WRF_DYNAMIC_SELECT004 - A maximum of 36 subroutine pools can be temporarily generated ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  SAP Error Message:
  WRF_DYNAMIC_SELECT004: A maximum of 36 subroutine pools can be temporarily generated
  
  
  Cause:
  This error occurs when the ABAP runtime environment tries to dynamically generate more than 36 subroutine pools during the execution of a program. In SAP, subroutine pools are internal containers for subroutines (FORM routines). When a program dynamically generates many subroutine pools (for example, due to dynamic SELECT statements or dynamic code generation), it can exceed the system limit of 36 temporary subroutine pools.
  This typically happens in scenarios involving:
  
  Dynamic SELECT statements with many different variants.
  Dynamic code generation or dynamic includes.
  Complex reports or programs that generate many dynamic subroutine pools at runtime.
  
  
  Explanation:
  
  SAP limits the number of dynamically generated subroutine pools to 36 to avoid excessive memory consumption and performance degradation.
  When this limit is exceeded, the runtime throws the error WRF_DYNAMIC_SELECT004.
