First of all, sorry for my bad english, i am from peru, and I`m working with Stella, doing some proyects for the university. I`d like to know how to get the sum of a flow element in diferent time. Iam planning to use an array, but the thing is that i dont kwno how to use it, wolud you help whit some basic example thanks!! Hello.

You can do this using the ARRAYSUM function. This is the description from the Help file: ARRAYSUM() The ARRAYSUM Builtin calculates the sum of all the elements in a given one or two dimensional Array. The calculation can be done in either an arrayed or a non-arrayed variable. When using the ARRAYSUM Builtin to report the sum across a one-dimensional arrayed variable, you must choose [*] from the secondary dialog, which indicates that you want the sum across all the elements within the variable. When using the ARRAYSUM Builtin to report the sum across a two-dimensional arrayed variable, it is possible to calculate it in three ways: To report the sum across both dimensions of the arrayed input variable, select [*,*] in the secondary dialog. You can report the arrayed variable's sum in either an arrayed or a non-arrayed converter or flow. Example: Total Salary for All Employees = Salaries[*,*] With this Builtin, you can also report a value across one dimension of the arrayed input variable, or roll up a value across (or down) one dimension of a two-dimensional arrayed variable into a one-dimensional arrayed variable. Hi Paula. You can do this using the ARRAYSUM function. This is the description from the Help file:

ARRAYSUM()
The ARRAYSUM Builtin calculates the sum of all the elements in a given one or two dimensional Array. The calculation can be done in either an arrayed or a non-arrayed variable.

When using the ARRAYSUM Builtin to report the sum across a one-dimensional arrayed variable, you must choose [*] from the secondary dialog, which indicates that you want the sum across all the elements within the variable.

When using the ARRAYSUM Builtin to report the sum across a two-dimensional arrayed variable, it is possible to calculate it in three ways:

To report the sum across both dimensions of the arrayed input variable, select [*,*] in the secondary dialog. You can report the arrayed variable’s sum in either an arrayed or a non-arrayed converter or flow.

Example:

Total Salary for All Employees = Salaries[*,*]

With this Builtin, you can also report a value across one dimension of the arrayed input variable, or roll up a value across (or down) one dimension of a two-dimensional arrayed variable into a one-dimensional arrayed variable.

Can you help me? Thank you Good afternoon:
