Hello,

I am wondering, how to "calculate" the following:

main table with following fields:

id

article number

article attributes calculated text

Subtable with following fields

id

relation to main id

article attributes number

a main record can have 0 to 5 subrecords

"article attributes number" contains numbers that should be calculated in "article attributes calculated text".

The formula of "article attributes calculated text" should do the following:

- Get all "article attributes number" (probably with the list command)

- Sort them in ascending order

- Write the sorted numbers with "-" between each Value

i.e. 3 Subrecords with numbers

8976

629

17678

calculated as 629-8976-17678

Can anyone tell me, how the calculation would look like?

Try:

Substitute ( List ( Subtable::article attributes number ) ; ¶ ; "-" )

The sorting should be done in the relationship's definition, which the List() function will faithfully follow.

Thanks a lot.

This is far from being "complicated".

I was constantly thinking, that I have to use "Let" and calculate Vars in special way and didn´t thought, there can be such an easy way.

Using Let() does not necessarily complicate thing - on the contrary, I often use Let() to make a formula more readable, sometimes even at the expense of perfect efficiency, e.g.

Let (

myList = List ( Subtable::article attributes number )

;

Substitute ( myList ; ¶ ; "-" )

)
