• What is the cause and solution for SAP error message IH048 - Only objects of the same category are allowed for list processing ?

  The SAP error message IH048, which states "Only objects of the same category are allowed for list processing," typically occurs in the context of SAP's Plant Maintenance (PM) or similar modules when you are trying to process a list of objects (like equipment, functional locations, etc.) that belong to different categories. This can happen when you attempt to perform operations on a selection of objects that are not compatible with each other.
  Cause:
  The primary cause of this error is that the system is trying to process multiple objects that do not belong to the same category. For example, if you are trying to generate a report or perform a mass change on a list that includes both equipment and functional locations, the system will throw this error because these two types of objects are categorized differently.
  Solution:
  To resolve the IH048 error, you can take the following steps:
  
  
  Check Object Categories: Ensure that all the objects you are trying to process belong to the same category. You can do this by reviewing the list of selected objects and confirming their types.
  
  
  Filter the Selection: If you have a mixed selection, filter your selection to include only objects of the same category. For example, if you are working with equipment, ensure that all selected items are equipment and not functional locations or other types.
  
  
  Use Appropriate Transactions: Make sure you are using the correct transaction codes or functions that are designed to handle the specific type of object you are working with. For example, if you are working with equipment, use transactions that are specifically for equipment management.
  
  
  Review Documentation: Check the SAP documentation or help files related to the specific transaction or function you are using. There may be additional guidelines or restrictions regarding the types of objects that can be processed together.
  
  
  Consult with SAP Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
