List report shows double rows for some of the Items which belongs to the spesific level in a hierarchy. Report contains Union Query and grouping.
Extra rows were shown on month level Item - list showed multiple identical rows under month level grouping where other columns also had identical values.
Product issue. Stitching of queries failed to match records with 'NULL' values correctly and remove corresponding rows. Design change to product code was made for Cognos 10.2.1 (10.2 RP1) where stitch functionality was improved introducing "StitchWithNulls" -parameter (ref. APAR PM83742).
