• What is the cause and solution for SAP error message PSB_API_MSGCL096 - Do not select different object types ?

  The SAP error message PSB_API_MSGCL096 with the description "Do not select different object types" typically occurs in the context of SAP Project System (PS) or related modules when there is an attempt to process or manipulate multiple object types in a single operation. This can happen in various scenarios, such as when trying to create or modify project structures, or when using APIs that expect a single object type.
  Cause:
  The error is triggered when the system detects that different object types (e.g., WBS elements, networks, activities) are being selected or processed together in a way that is not allowed. This can happen due to:
  
  Mixed Object Types: You are trying to perform an operation that involves multiple object types in a single request.
  Incorrect API Usage: The API or function module being called is designed to handle only one type of object at a time.
  Data Input Issues: The data being passed to the function or API may include a mix of different object types.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Object Types: Review the objects you are trying to process and ensure that they are all of the same type. For example, if you are working with WBS elements, make sure that all selected objects are WBS elements and not a mix of WBS elements and networks.
  
  
  Separate Operations: If you need to process different object types, separate them into different operations. For instance, handle WBS elements in one call and networks in another.
  
  
  Review API Documentation: If you are using an API or function module, refer to the SAP documentation to understand the expected input and ensure that you are adhering to the requirements.
  
  
  Debugging: If you are developing custom code, use debugging tools to trace the values being passed to the function or API. This can help identify where the mix of object types is occurring.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address this issue, as there may be known bugs or patches available.
  
  
  Related Information:
  
  SAP Project System (PS): This module is used for project management and controlling within SAP. Understanding the structure and types of objects in PS can help in troubleshooting.
  Function Modules and APIs: Familiarize yourself with the specific function modules or APIs you are using, as they often have specific requirements regarding input parameters.
  SAP Community and Forums: Engaging with the SAP community can provide insights from other users who may have encountered similar issues.
