We exported autoforecasts and the csv had almost nearly 20000 lines but never more than that. As notorious optimist I set the parameter GENERIC_AUTO_FORECAST_LIMIT to 100000 and got an autoforecast with the default of 5001 lines only (5000 lines output + 1 headline). Therefore I thought it might count. But of course asking is better. I would be really glad to know how to increase the forecast-range.

Is there any chance that GENERIC_AUTO_FORECAST_LIMIT is taken into account at autoforecast generation time?
I don't think it does, and it shouldn't, but I thought I'd ask anyway.

We are on 12.3.0 hf1, and consider autoforecast to be broken. At first we thought it was working, but it was actually failing part-way-thru without any warning, so the results were always incomplete.
Consequently, we wrote our own forecast script. We used it successfully last month for a major planned outage. It has several design limitations. It only forecasts for one day at a time (which is typically what we need to look at anyway), and only forecasts JSCH schedules. It doesn't know how to forecast objects that automatically repeat. The results are saved in csv format. Anyway, I share the code with those that private message me with their email address.

We just upgraded to 12.3.6 HF1. We are facing the same issue.
Based on your information, we also reduced the number of days from 21 to 10 day. While the forecast does complete, the results are less than accurate. Not all the objects in the forecast is completed as well as not expandable. There are some objects showing the status as exceed Timeout.

We upgraded our testsystem from v12.3.5hf1 to v12.3.6hf2. After that we have encountered a problem with autoforecast:
We run the autoforecast for a 60 days intervall. After the update there is a memory-problem with the JWP: the process always crashes during calculating the autoforecast. Trying to increase the heapspace of the JWP to 6GB didn't fit the bill, it still crashes.
The suggestion from the support: run the Autoforecast for less than 10 days to avoid problems with the memory.
This can't be the solution. In our production system we have much more schedules and tasks to be calculated! Does anyone have a similar problem with autoforecast and maybe have a clue for me?
Greetings
Bernhard
