  The SAP error message OL625 indicates that there is an issue with the data model configuration in the SAP system. Specifically, it means that an object type has already been maintained for the specified data model, which prevents you from making further changes or additions to that data model.
  Cause:
  The error typically arises in the context of data modeling, where you are trying to maintain or modify an object type (like a characteristic, key figure, or other data model elements) that has already been defined for the specified data model. This can happen due to:

  Consult Documentation: Refer to the SAP documentation or help resources for guidance on maintaining object types in data models. This can provide insights into best practices and restrictions.
