Hey Guys,
 
Got myself a stupid problem, but i guess (hope) there a easy sollution
 
I have grouped my detail on a field called artcode
 
in my detailed i have for every artcode some value's if there was a stock mutation on that article / value of that item @ that moment / ...  in a given time period (parameter on date field)
 
now i get somthing like this
 
 
group:    volgnr          Totmutations           TotValue
detail:     volgnr          stockmutation          Value
 
Becouse there are sometimes more then 1 mutation on a article during a time period (for example there is -1 on a article but couple days later they find it back and they do a +1 on that stock possition of that article) i have to group on volgnr
 
in the end i get somthing like this
 
volgnr     totmutation     TotValue
300561         -2                  -15€
300681          3                    75€
306857        -11                -120€
...
 
you get the picture
 
now i would like to sort this list on the TotValue field but when i try to select that formula in the record sort expert (the A-Z symbol) it's not availeble.
I understand why it's not availeble as the totvalue is only calculated in the group and not in the detail so i can't record sort on it.
 
But what to do then ?
 
Hope somebody know a way arround.
 
Tnx in advance

If it can be calculated using the insert Summary function and you can group instead of use details then you can use the TOP N function for sorting.
Otherwise you would have to do your calcs in a stored proc (or some other source level option) to sort on it.

hey Dblank,
 
I can select the value field now (remade it so it's a calculated field from the detail line.
 
I can now select the field in my detail sort expert but that doesn't change a thing.
It sorts the value's now in every group
i can't put it higher on the list eather in the sort expert.
 
The group goos first then the value

So you want the Volgnr to be sorted by the TotValue?

IF my detail would give me
 
300681     2                     40
306857    -10                 -100
300561     1                     7.5
300561   -3                      -15
306857      -1                  -20
300681       1                   35
 
 
Then now i get
 
300561         -2                  -15€
300681          3                    75€
306857        -11                -120€
 
And what i would like to get it
 
306857        -11               -120
300561         -2                -15
300681          3                  75
 
So first it groups on the volgnr and then it sorst on the value (high - low or low-high)

keep your Volgnr group

Insert a Summary as a SUM of Tot at the Volgnr LEvel
Use the TOP N Group Sort using the SUM you just created
selecting the Sort as TOP N making N a # larger than all your VOLGNRS
