Error description

• When a business process definition (BPD) starts a linked
  subprocess, its due date might be specified by using local
  variables. In IBM Business Process Manager (BPM) V8.5.7.0, due
  dates specified with local variables might lead to
  UndeclaredVariableRuntime exceptions:
  
  The following example is a typical stack trace for this issue:
  com.lombardisoftware.server.core.UndeclaredVariableRuntimeExcept
  ion: Undeclared local variable, input or output parameter date2
  found in service "P1" item "UNKNOWN" location "UNKNOWN". You
  must declare it in order to use it.

Local fix

Problem summary

• Because IBM BPM V8.5.7.0 uses the variables of the top-level BPD
  to evaluate the due date of the actual (linked) process, you
  receive an exception because the actual specification uses a
  local variable from the linked BPD, which is not included in the
  list of variables from the top-level BPD.
  

Problem conclusion

• A fix that uses the correct symbol table to evaluate the due
  date of a linked subprocess will be included in an upcoming IBM
  Business Process Manager (BPM) V8.5 cumulative maintenance
  vehicle.
  
  To determine whether the cumulative fix is available and
  download it if it is, complete the following steps on Fix
  Central:
  
  1. Select IBM Business Process Manager with your edition from
    the product selector, the installed version to the fix pack
    level, and your platform, and then click Continue.
  
  2. Select Text, enter ?cumulative fix?, and click Continue.
