2119064 - Bad query performance, InfoCube table statistics never updated

Symptom

The performance of a query has decreased although you did not change its structure recently. The SQL-statement shows a long lasting access on InfoCube tables.

  • The cube statistics show a yellow traffic light in transaction RSA1 -> InfoCube Manage -> Performance tab.
  • A refresh of the statistics does not work, neither manually in transactions RSA1, RSRV nor with BRCONNECT or in a Process Chain. The statistics check remains yellow.

The initial filling of aggregates may also be influenced by this problem.
