• What is the cause and solution for SAP error message SWDP_WB_TOOL812 - Namespace & is not allowed in name & ?

  The SAP error message SWDP_WB_TOOL812 indicates that there is an issue with the namespace used in the name of an object, typically in the context of SAP Web Dynpro or other development environments within SAP. The error message states that the namespace is not allowed, which usually means that the naming convention or the namespace used does not comply with SAP's standards.
  Cause:
  
  Invalid Namespace: The namespace used in the object name does not conform to the allowed naming conventions. In SAP, namespaces are often defined for different development objects, and using an invalid or unregistered namespace can lead to this error.
  Missing Registration: If you are trying to use a custom namespace that has not been properly registered in the SAP system, you will encounter this error.
  Incorrect Object Naming: The object name may contain invalid characters or formats that are not permitted by SAP.
  
  Solution:
  
  Check Namespace: Ensure that the namespace you are using is valid and registered in the SAP system. You can check this in the transaction SE80 (Object Navigator) or SE11 (Data Dictionary).
  Use Standard Namespace: If you are not required to use a custom namespace, consider using the standard namespace provided by SAP (e.g., Z or Y for custom developments).
  Correct Naming Convention: Make sure that the object name adheres to SAP's naming conventions. Typically, custom objects should start with Z or Y, followed by a valid name.
  Register Custom Namespace: If you need to use a custom namespace, ensure that it is properly registered in the SAP system. This can usually be done through the SAP namespace registration process.
  Consult Documentation: Refer to SAP documentation or guidelines regarding naming conventions and namespaces to ensure compliance.
