You created a calculated column in a star join view but received incorrect results. What is a possible reason?

Having not enabled the Keep Flag is indeed a plausible reason for receiving incorrect results from a calculated column in a star join view. The Keep Flag is utilized to ensure that specific rows and data relationships are preserved during various operations within the calculation. When the Keep Flag is not set, the underlying data may not retain necessary relationships or aggregations, leading to skewed or erroneous outcomes in the calculated column.

This option underscores the importance of maintaining data integrity and accurately capturing the intended relationships within the data model. The Keep Flag ensures that the necessary filtering and context necessary to compute the calculations correctly are preserved. Without this crucial step, calculations could draw from incomplete or inaccurate sets of data, leading to incorrect results.

This focus on maintaining data relationships encapsulates a fundamental aspect of designing star join views and working within the SAP HANA environment, emphasizing the need for careful configuration to achieve accurate analysis and reporting.
