If you are running BPM and you are not using B2B, you might want to disable the DBMS job that refreshes the B2B materialized view.  This job runs every minute by default.

To find the job, use a query like the one below.  Update the schema user to match the environment:

select
  job
, schema_user
, broken
, what
, interval
from
  dba_jobs
where
  schema_user = “DEV_SOAINFRA”

Look for the job which contains something like the following in the WHAT column.  Note that it may be different if a different schema prefix was used in the environment.

dbms_refresh.refresh('"DEV_SOAINFRA"."B2B_SYSTEM_MV"');

To remove the job, take note of the job number from the JOB column and then use a command like the following, substituting in the correct job number in place of 24:

begin
dbms_job.remove(24);
end;

Alternatively, alter the materialized view to be refreshed on demand, using a command similar to this:

alter materialized view dev_soainfra.b2b_system_mv refresh on demand;
