Deal all,
I'm learning about E.P and make an actual scenarios. For exercising purpose, I run the start/end date forward and backward several times. All of them are ok until suddenly I can't run cprpd4200m000 (initialize, roll and update scenario), there's an error message: "Multiplier 2-D Calendar Arrays too small. Program (cprmpdll0001) Aborted."

I've checked calendar, period and so on. They all are seem ok, but still I can't run the sessions.

Can anyone help me please?

cpcom0100s000 Performance Parameters
Change value to 7. Should work. If not change

Tq Flip_J! It works!
But I still don't know why. Is it regarding with the calendar calculation or something?

Don't realy know. Just knows it solves the problem

The 2-D multiplyer handles the 'depth' of the Calendar arrays.
The bigger the value, the more 'depth'you get in your Calendars and thus the more precise your planning.
You can compare it with 'screen-resolution'.
It kind of makes the difference in storing your Calendars in years, months, weeks, days, hours, minutes, seconds. The higher the multiplyer, the smaller the time-scales.

So by putting in a large multiplyer, you get (almost) perfect planning.
The cost of it all is HUGE performance loss! (


The suggestion by Flip_J to raise it to 7 is quite alright.
In general you simply should try several values.....

Never use values above 10! (unless your server is a real monster)
When you need planning accuracy that demands multiplyers above 10, you're probably using the wrong software...... ;)
