  The SAP error message SADL_GW_DT_CDS068 typically occurs in the context of SAP Gateway and Core Data Services (CDS) when there is an issue with the definition of a text node in a CDS view. The error indicates that a specific element (field) in the text node must be defined as a key field, but it is not.
  Cause:
  The error arises when:
  
  A text node is defined in a CDS view, but the required key field(s) are not properly specified.
  The text node is expected to have a unique identifier (key) that is necessary for the proper functioning of the data model, especially when dealing with translations or text elements.
  The CDS view is not adhering to the expected structure for text nodes, which typically require a key field to ensure that the text can be uniquely identified.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the CDS View Definition:
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant development environment.
  Ensure that the text node is correctly defined and that it includes a key field.
  
  
  
  Define Key Fields:
  
  Identify the field(s) that should serve as the key for the text node. This could be a combination of fields that uniquely identify the text entries.
  Modify the CDS view to include these key fields in the text node definition.
  
  
  
  Example of Correct Definition:
  Here is a simplified example of how a text node might be defined correctly in a CDS view:
  define view Z_CDS_View
  as select from your_table
  {
      key field1,
      key field2,
      field3,
      ...
      textnode your_textnode
      {
          key field1,
          key field2,
          text_field
      }
  }
  
  
  Activate the CDS View:
  
  After making the necessary changes, activate the CDS view to ensure that the changes take effect.
