* Session Variables: * Session Variables are data items whose values can be changed while a process is running. * Updating Session Variables: * Variable Repository in System Manager (Option A & B): This refers to managing variables at the system level, which is not used for updating running process variables directly. * Calculation Stage (Option C): This can be used within the process to update the value of a session variable during runtime. * Control Room (Option D): Allows operators to update session variable values for running processes via menu options. * Conclusion: * The correct methods to update the value of a data item exposed as a 'Session Variable' while the process is running are: * C. Through a Calculation stage in the same process. * D. Selecting the running Process in Control Room and then using the menu options to push a new value to the data item.
