Parameter Mapping from Parent Process to Subprocess

Process Design
1

I am using direct process data mapping for passing data from a parent process to a subprocess. (Not using GETPROCESSDATA) I continually get a warning in my parent process that the direction of my parameter that is passed to the subprocess does not match the direction of that parameter in the subprocess. However, I have used this direct parameter mapping to send and receive process data with another subprocess without this issue.

  • The parameter in my parent process is I_T_M. It has no direction defined in the parameters list for the parent process.
  • The parameter in my subprocess is T_M. T_M is defined in the parameter list as INOUT. It is defined as INOUT in the first action of the subprocess and INOUT from the last action of the subprocess.
  • In the action that calls the subprocess, T_M is defined as an INOUT parameter and I_T_M is the parameter from which the T_M is filled and into which T_M is sent.

So, why am I getting the warning that the OUT direction of T_M in the parent process action that calls the subprocess does not correspond to the INOUT direction of the data in the subprocess?
