• What is the cause and solution for SAP error message DD_CDS_ANALYSIS202 - Annotation data category is missing ?

  The SAP error message DD_CDS_ANALYSIS202 indicates that there is a missing annotation for the data category in a Core Data Services (CDS) view. This error typically arises when the CDS view is expected to have a specific annotation that defines the data category, but it is not present.
  Cause:
  The error is caused by the absence of the required annotation in the CDS view definition. The annotation that is usually missing is @Analytics.dataCategory, which specifies the data category of the CDS view (e.g., #DIMENSION, #FACT, etc.). Without this annotation, the system cannot determine how to handle the data in the context of analytics.
  Solution:
  To resolve this error, you need to add the missing annotation to your CDS view definition. Here’s how you can do it:
  
  
  Open the CDS View Definition: Access the ABAP Development Tools (ADT) in Eclipse or the relevant transaction in the SAP GUI where the CDS view is defined.
  
  
  Add the Annotation: Include the @Analytics.dataCategory annotation in the CDS view definition. For example:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @Analytics.dataCategory: #DIMENSION  // or #FACT, depending on your use case
  define view Z_MY_CDS_VIEW as select from my_table
  {
      key field1,
      field2,
      ...
  }
  
  
  Activate the CDS View: After making the changes, activate the CDS view to ensure that the new annotation is recognized by the system.
  
  
  Test the CDS View: Execute the CDS view to verify that the error has been resolved and that the view behaves as expected.
