• What is the cause and solution for SAP error message PPEXPL_CMP001 - Class where-used list chosen is not supported ?

  The SAP error message PPEXPL_CMP001 indicates that the "where-used list" functionality you are trying to access is not supported for the selected class. This typically occurs in the context of class-based object-oriented programming in SAP, particularly when dealing with classes in the SAP ABAP environment.
  Cause:
  
  Unsupported Class Type: The class you are trying to analyze may not support the where-used list functionality. This can happen if the class is not defined in a way that allows for such analysis.
  Technical Restrictions: Certain classes, especially those that are not instantiated or are abstract, may not have a where-used list.
  System Configuration: There may be system settings or configurations that restrict the use of where-used lists for certain types of classes.
  
  Solution:
  
  Check Class Type: Ensure that the class you are trying to analyze is a concrete class and not an abstract class or interface. Only concrete classes typically have a where-used list.
  Use Alternative Tools: If the where-used list is not available, consider using other tools or transactions in SAP to analyze dependencies, such as:
  
  SE80: Object Navigator, where you can explore the class and its components.
  SE11: Data Dictionary, to check related database objects.
  SE37: Function Module, to see if there are function modules that utilize the class.
  
  
  Check Documentation: Review the SAP documentation or help files for the specific class to understand its capabilities and limitations.
  Consult with SAP Support: If you believe this is an error or if the class should support a where-used list, consider reaching out to SAP support for further assistance.
  
  Related Information:
  
  Class Types in ABAP: Understanding the different types of classes (abstract, concrete, interfaces) can help in determining the capabilities of a class.
  SAP Notes: Check for any relevant SAP Notes that might address this issue or provide additional context.
  Development Guidelines: Familiarize yourself with SAP's best practices for class design and usage, which can help avoid such issues in the future.
  
  By following these steps, you should be able to address the error and understand the limitations of the where-used list functionality in SAP for the specific class you are working with.
