• What is the cause and solution for SAP error message WSTI_MODEL003 - Select one Customizing schema as standard ?

  SAP Error Message:
  
  WSTI_MODEL003: Select one Customizing schema as standard
  
  Cause:
  This error occurs when you are working with SAP Solution Manager's IT Service Management (ITSM) or Change Request Management (ChaRM) and you have not designated exactly one Customizing schema as the standard schema in the system. The system requires that among the available Customizing schemas, one must be explicitly marked as the standard to ensure consistent behavior during transport and change management processes.
  In other words, either no Customizing schema has been set as standard, or more than one schema has been marked as standard, which leads to ambiguity.
  
  Solution:
  
  
  Check Customizing Schemas:
  
  Go to the transaction or customizing node where Customizing schemas are maintained. This is typically done in the Solution Manager or ChaRM customizing.
  The path might be:
  
  SPRO -> SAP Solution Manager -> Change Request Management -> Basic Settings -> Define Customizing Schemas
  
  
  
  Set Exactly One Schema as Standard:
  
  Review the list of Customizing schemas.
  Ensure that exactly one schema is flagged as the standard schema.
  If none is set, select the appropriate schema and mark it as standard.
  If more than one is set, deselect the standard flag from all but one schema.
  
  
  
  Save and Transport:
  
  After setting the standard schema, save your changes.
  If necessary, create and release a transport request to move the changes to other systems.
  
  
  
  Verify:
  
  Retry the operation that caused the error.
  The error should no longer appear once the standard schema is correctly set.
  
  
  
  
  Related Information:
  
  
  Customizing Schema:
  
  A Customizing schema in SAP Solution Manager defines a set of customizing objects that are grouped together for transport and change management purposes.
  
  
  Why is a Standard Schema Needed?
  
  The standard schema acts as the default reference for customizing changes and ensures that the system knows which set of customizing objects to consider as the baseline.
  
  
  Where is this Relevant?
  
  This error is commonly encountered in SAP Solution Manager when configuring Change Request Management (ChaRM) or IT Service Management (ITSM) processes, especially when dealing with transport routes and customizing transports.
  
  
  SAP Notes and Documentation:
  
  For more detailed guidance, you can refer to SAP Notes related to ChaRM and Customizing schemas, or the official SAP Solution Manager documentation.
