Introduction
Many SAP queries and ABAP reports do not perform well when retrieving large volume of data from traditional databases using complex SELECT – JOIN SQL statements often on 10 or more tables containing millions of records.
If these ABAP reports are standard SAP programs or ABAP programs generated by SAP in applications like, e.g., SAP SQ01 Query, they should not be modified by programmers. However, using them is frustrating because of poor performance and timeouts they cause for broad selection screen criteria.
