  Technical Restrictions: Certain attributes may have technical restrictions that prevent their names from being changed after they have been created.

  Review Technical Restrictions: Consult the documentation or SAP support to understand if there are any technical restrictions on changing the attribute names. If there are, you may need to consider alternative approaches.
  Validate Metadata: Use transaction codes like RSA1 (for BW) or HANA Studio to validate the metadata of the data container. Look for any inconsistencies and resolve them.
