  ****************************************************************
  If an API request is made against a recoverable user maintained
  data table (or Coupling Facility Data Table) while it is being
  loaded as part of open processing by another task.
  The FLAB for the transaction issuing the API request does not
  set flab_do_not_close or flab_recoverable_work_done off.
  This leads to CEMT displaying "Close requested" against the
  file indefinitely.
  Keywords: CFDT
  

Problem conclusion

• DFHFCFR has been changed to include the fcfr_reason of
  fcfr_loading in its list of reasons to ensure that the
  flab fields are set off before exiting the module. Note - this
  fix caters for both UMDTs and CFDTs.
