I found out there is a huge difference between using ISNULL(table.column) = 1 and different type of writing this formula (table.column) IS NULL. Do you have know from where this difference comes from ?
Here is example from analysis:
ISNULL(“BKPF”.“KBR_KONT_FLAG”) = 1“
“BKPF”.“KBR_KONT_FLAG” IS NULL
