  The SAP error message /UI5/DEL_ADAP_PRJKT002 Invalid layer: You can only delete app variants from CUSTOMER_BASE typically occurs when you are trying to delete an application variant that is not in the CUSTOMER_BASE layer. In SAP, application variants can exist in different layers, such as CUSTOMER, DEVELOPMENT, and TRANSPORT. The CUSTOMER_BASE layer is specifically meant for customer-specific adaptations.
  Cause:

  Use the Right Tools: Ensure you are using the correct tools or transactions to manage app variants. For example, you might use the SAP Fiori App Library or the Adaptation Project tool to manage your app variants.
