Hi,
ORA-20000: index "SAPSR3"."/BIC/B0000598000KE" or partition of such index is in unusable state
rebuild the index using BRTOOLS.
Run brtools
select 3 --> SEGMENT MANGEMENT -->  2 - Rebuild indexes -->  7 ~ Index names (index)
provide your index name here SAPSR3"."/BIC/B0000598000KE
and rebuild the index
after running rebuild index , start again Update Statistics.
it will run succesful
Thanks
