• What is the cause and solution for SAP error message SD_CDS_ENTITY112 - Function AVG is only allowed with addition "as" ?

  The SAP error message SD_CDS_ENTITY112 indicates that there is an issue with the use of the AVG function in a Core Data Services (CDS) view or query. Specifically, the error states that the AVG function can only be used with the AS addition, which is required to define an alias for the result of the aggregation.
  Cause
  The error typically occurs when you are trying to use the AVG function in a CDS view or query without providing an alias for the result. In SQL and CDS, when you perform an aggregation, you must specify an alias to identify the resulting column.
  Solution
  To resolve this error, you need to modify your CDS view or query to include the AS keyword followed by an alias for the result of the AVG function. Here’s an example of how to correctly use the AVG function in a CDS view:
  Incorrect Usage
  define view ZMyCDSView as
  select from my_table
  {
      key field1,
      avg(field2)  // This will cause the error
  }
  Correct Usage
  define view ZMyCDSView as
  select from my_table
  {
      key field1,
      avg(field2) as average_field2  // Correct usage with alias
  }
