• What is the cause and solution for SAP error message RS2HANA_VIEW050 - Skip key figure &1: Datatype TIMS/DATS with SUM aggregation not supported ?

  The SAP error message RS2HANA_VIEW050 indicates that there is an issue with the aggregation of key figures in a HANA view, specifically when dealing with the data types TIMS (time stamp) or DATS (date) using the SUM aggregation function. This is not supported in SAP HANA views because summing date or time values does not have a meaningful interpretation.
  Cause:
  The error occurs when you attempt to aggregate a key figure that is of type TIMS or DATS using the SUM function in a HANA view. Since dates and timestamps represent specific points in time, summing them does not yield a valid result, which is why the system raises this error.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Change Aggregation Method:
  
  Instead of using SUM, consider using other aggregation methods that are more appropriate for date or time data types. For example, you might use:
  
  MIN: To get the earliest date or time.
  MAX: To get the latest date or time.
  COUNT: To count the number of occurrences.
  
  
  
  
  
  Remove the Key Figure from Aggregation:
  
  If the date or time key figure is not necessary for your analysis, you can remove it from the aggregation in the HANA view.
  
  
  
  Convert to a Different Data Type:
  
  If you need to perform calculations that involve dates or times, consider converting the date or time to a numeric representation (e.g., converting to a timestamp in seconds since a certain epoch) before performing the aggregation. However, this approach should be used with caution, as it may complicate the interpretation of the results.
  
  
  
  Review Business Requirements:
  
  Reassess the business requirements to ensure that the aggregation of date or time values is indeed necessary. Sometimes, the requirement can be adjusted to avoid this issue altogether.
  
  
  
  Related Information:

  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error message.
  Data Modeling Best Practices: Familiarize yourself with best practices for data modeling in SAP HANA, especially regarding the handling of date and time data types.
  
  By following these steps, you should be able to resolve the RS2HANA_VIEW050 error and successfully aggregate your data in the HANA view.
