Invalid Expression Error

[Anonymous]

Hi All,

My script in qlikview gives an error as "Invalid Expression" while reloading and fails.

I am not sure about this error.

Any idea why qlikview throws an error like this and is there any solution for this?

I am using Sum, the code goes like this:

Temp2:

Load
[Key_ID],

(sum(Total_resource) * 13 * 7/

//PHASE 1

If([Cat1] = 'PHASE 1',
If([Cat2] = 'Phase 1',
If([E_Num]=[P_Id] and [E_Type]='Phase Review Decision - Cancelled',
  If(IsNull([St_Dt]), [E_Dt] - [PC_Dt], [E_Dt] - [St_Dt]),
   If(IsNull(MAXSTRING([L_Dt])),
   If(IsNull([St_Dt]), Today() - [PC_Dt], Today() - [St_Dt])
   ,
   If(IsNull([St_Dt]), MAXSTRING([L_Dt]) - [PC_Dt], MAXSTRING([L_Dt]) - [St_Dt]))),
  
If([Actual_dur_1] >=1, [Actual_dur_1], 0))
)
)as [source]

Resident Temp1;

and it goes on for n number of phases, I have separated to check what's wrong.

I tried using Group By, but was not able to make this work.

Appreciate your help.

sum(Total_resource)

this syntax only worked with group by .

so this gives the error in your expression

Thanks vishwaranjan.

I already tried using group by but it didn't work.

[#5]

Load
[Key_ID],

sum(Total_resource)  as [source]

Resident Temp1 Group by [Key_Load];

Just try to load this

It is reload without error  then error is in if statement

else it is reload with error then Total_resource might be text field

try this,

Temp2:

Load
[Key_ID],

(sum(Total_resource) * 13 * 7/

//PHASE 1

Sum(If([Cat1] = 'PHASE 1',
If([Cat2] = 'Phase 1',
If([E_Num]=[P_Id] and [E_Type]='Phase Review Decision - Cancelled',
  If(IsNull([St_Dt]), [E_Dt] - [PC_Dt], [E_Dt] - [St_Dt]),
   If(IsNull(MAXSTRING([L_Dt])),
   If(IsNull([St_Dt]), Today() - [PC_Dt], Today() - [St_Dt])
   ,
   If(IsNull([St_Dt]), MAXSTRING([L_Dt]) - [PC_Dt], MAXSTRING([L_Dt]) - [St_Dt]))),
  
If([Actual_dur_1] >=1, [Actual_dur_1], 0))
) )
)as [source]

Resident Temp1;

Thanks for the response Kabilan.

Total_resource is a numeric field.

I tried the second option also, but it gives an error as :

Error: Error in expression:

Nested aggregation not allowed

If u r using Sum(Total_resource), then do group by...otherwise try below..

Temp2:

Load
[Key_ID],

Total_resource * 13 * 7/

//PHASE 1

If([Cat1] = 'PHASE 1',
If([Cat2] = 'Phase 1',
If([E_Num]=[P_Id] and [E_Type]='Phase Review Decision - Cancelled',
  If(IsNull([St_Dt]), [E_Dt] - [PC_Dt], [E_Dt] - [St_Dt]),
   If(IsNull(MAXSTRING([L_Dt])),
   If(IsNull([St_Dt]), Today() - [PC_Dt], Today() - [St_Dt])
   ,
   If(IsNull([St_Dt]), MAXSTRING([L_Dt]) - [PC_Dt], MAXSTRING([L_Dt]) - [St_Dt]))),
  
If([Actual_dur_1] >=1, [Actual_dur_1], 0))
)
