Read Percenatge and Time from a Global Table

Hi there,

How can I retrieve the percentage and processing times for a specific process from the global table? In other words, I have a particular process that, for X% of the time, it takes TR (1,3,2), and for Y% of the time, it takes TR (10,13,11), and so on. I want the process to access the global table, read the percentage and time split, and execute accordingly.

Thanks

Format the table to have on column contain the percentage chance that the respective row is used. And another columns is set to contain a FlexScript function that returns a value from the given dsitribution (RightClick -> Assign Data -> Assign FlexScript Data).

Note that for the fourth parameter, where you would normally see something like getstream(activity), we use param(1). The random number stream will later be passed into the function when we call it from the Patient Flow.

Getting the time value is a two step process. First determine which row to use by using the By Percentage option in the assign labels activity. Now that the row number is known we use Table().cell() to access the node where the cell value is stored rather than the value itself. Since the node contains FlexScript code, it can be executed by using evaluate(), passing in the random number stream belonging to the current activity.

Alternatively you could also store the Min, Max, Mode values in separate columns and then pass those into the distribution once the row is known.
