IF Statement Calculation

Wed, 18 Jan 2017 19:41:58 GMT

I have the following If statement in the load script but it is an invalid expression. Does anyone have any thoughts on how i can make this work?

IF((Match(Type,'FTE') and sum(Number)) > (Match(Type,'ACTUAL') and sum(Number)),'OVERSTAFFED','UNDERSTAFFED')

You should set a flag for Type = FTE and using the Flag you can create a expression in UI.

Else you can use below the expression in UI

if(sum({<Type={"FTE"}>}Number)>sum({<Type={"ACTUAL"}>}Number),'OVERSTAFFED','UNDERSTAFFED')

Are you using the expression in Load statement or assigning the value to a variable?

I am using it in the load statement, I know i can do it in the UI but i need it done in the load script.

This is a flat data table is one of my constraints.

It won't work so easily in script with the reason of having aggregation involved, you may try as below -

1. First calculate sum(number) using where clause and group by clause in separate table

2. join the sum no to the old table so that sum field is available in all records

3. then compare the type field with the new sum field as you are trying to do.

May not completely correct, if you share your script, can add something further.

Zeth,

It's hard to say without more info. Making some assumptions you could do something like this:

Data:

LOAD * INLINE [

Team, Type, Number

A, Actual, 4

A, Actual, 3

A, FTE, 6

B, Actual, 1

B, Actual, 2

B, FTE, 4

];

Summary:

load *,

if(Actual>FTE,'OVERSTAFFED','UNDERSTAFFED') as Status

;

load

Team,

Sum(ActualNbr) as Actual,

Sum(FTENbr) as FTE

group by Team

;

load

Team,

if(Type='Actual',Number,0) as ActualNbr,

if(Type='FTE',Number,0) as FTENbr

resident Data

;

It would give you an output like this.
