• What is the cause and solution for SAP error message WOST_WSSO_TOOLS001 - Select at most one Customizing schema as standard ?

  The SAP error message WOST_WSSO_TOOLS001 with the description "Select at most one Customizing schema as standard" typically occurs in the context of customizing settings in SAP, particularly when dealing with the configuration of customizing schemas in the SAP system.
  Cause:
  This error arises when you attempt to set more than one customizing schema as the "standard" schema in the system. In SAP, a customizing schema defines how certain settings and configurations are applied, and only one schema can be designated as the standard for a particular area of configuration. If multiple schemas are marked as standard, the system cannot determine which one to use, leading to this error.
  Solution:
  To resolve this error, follow these steps:
  
  
  Access the Customizing Settings:
  
  Go to the relevant transaction code in SAP where you can manage customizing schemas. This is often done through transaction codes like SPRO (SAP Project Reference Object) or specific customizing transactions related to your module.
  
  
  
  Review Customizing Schemas:
  
  Navigate to the section where customizing schemas are defined. Look for the list of schemas that have been created.
  
  
  
  Identify Standard Schema:
  
  Check which schemas are currently marked as standard. You should see a flag or indicator that shows which schema is set as standard.
  
  
  
  Adjust the Settings:
  
  If you find that more than one schema is marked as standard, you will need to deselect the standard flag for all but one schema. Ensure that only one schema is designated as the standard.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save your changes.
  
  
  
  Test the Configuration:
  
  After resolving the issue, test the configuration to ensure that the error no longer appears and that the system behaves as expected.
