Statistics for SM50

Hello,

a look into transaction SM50 shows all running workprocesses at the moment. You can see for example10 running DIA's and 2 running BTC's.

But how to research the maximum number of running DIA's at the same time for a whole day, week or month?

With this information I want to be able to forecast if the number of configured DIA's will be enough for a greater system load in the near future.

For example: 10.000 outbound deliveries processed by 20 SAP-users need a maximum of X DIA's in my EWM-System. I want to prove if the double system load (20.000 delieveries, 40 SAP-users) needs the double maximum DIA's. I want to research the value of X in the running system for a day.

Thanks for any hints.,

Werner
