Hi Jakapong -
This could arise if you have specified non-zero Historical Production for a process, but the process' Maximum Availability variable is zero (or, contains a yearly shape which has a zero value in the first time slice). Check the Maximum Availability variable for the Onshore Pipe Gas process.
I notice that the issue appears in year 2032. What is the First Simulation Year set to? Note that Historical Production is used for all years beginning in the model's Base Year, up to (but not including) the First Simulation Year.
Best,
Taylor
