• What is the cause and solution for SAP error message ESH_ENG_CDSVAL_ES020 - 'presentationMode' HIDDEN cannot be combined with others (&1) ?

  The SAP error message ESH_ENG_CDSVAL_ES020 typically occurs in the context of SAP's Enterprise Search or when working with Core Data Services (CDS) views. This error indicates that there is a conflict in the presentation mode settings of the CDS view, specifically that the HIDDEN presentation mode cannot be combined with other modes.
  Cause:
  The error arises when you attempt to define a field in a CDS view with the HIDDEN presentation mode while also trying to use other presentation modes (like DEFAULT, FILTER, etc.) for the same field or in the same context. The HIDDEN mode is intended to make a field invisible in the user interface, and it cannot coexist with other modes that imply visibility or interaction.
  Solution:
  To resolve this error, you should review the definition of your CDS view and the presentation modes assigned to the fields. Here are steps you can take:
  
  
  Check Field Definitions: Look at the fields in your CDS view and identify which ones are set to HIDDEN. Ensure that no other presentation modes are being applied to the same fields.
  
  
  Modify Presentation Modes: If you need a field to be HIDDEN, ensure that it is not combined with other presentation modes. If you need the field to be visible or interactive, consider removing the HIDDEN mode.
  
  
  Review Annotations: If you are using annotations to define presentation modes, ensure that they are correctly specified and do not conflict with each other.
  
  
  Test Changes: After making the necessary adjustments, activate the CDS view and test it to ensure that the error is resolved.
