Unexpected Token

[AkbarShaikh]

Hello guys,

I have purchased this book Qlikview: Advanced Data Visualization and as an example, it is creating a random set of data. 

I am scripting as per the book, but still getting an Unexpected token error. I have tried every option to resolve this, but not able to get past this error. 

I have attached the script and the error message for reference. 

Any help would be highly appreciated. 

Thanks,

Akbar

// ***************This is the script as mentioned in the book ********************** //

//Calculate random number of lines

FOR L = 1 to $(vPCount)
//Calculate random values

LET vRnd = Floor (Rand() * $(vProdCount));
LET vPID = Peek ('ProductID', $(vRnd), 'Product');
LET vCost = ApplyMap('Product_Cost_Map', $(vPID), 1);  // *****This is where the error hits in *****//
LET vPrice = ApplyMap('Product_Price_Map' ,$(vPID), 1);

Try this:

LET vCost = ApplyMap('Product_Cost_Map', '$(vPID)', 1); 
LET vPrice = ApplyMap('Product_Price_Map' ,'$(vPID)', 1);

Thank you for the reply, I had tried using ' ' on the variable, but it still gives an error.

Applymap always go along with a mapping table.

Do you have a mapping table above your script?

Eg:

Product_Cost_Map:

Mapping load

Key,MapField

inline [

Key,MapField

Key1,A

Key2,B

];

Hi Fong, I have a preceding Mapping Load of the with both the table names separately with two fields. //************This is the preceding load script*****// Product_Cost_Map: Mapping Load ProductID, NUM(CostPrice) Resident Products; //This table is already loaded with ProductID, CostPrice, SalesPrice Product_Price_Map: Mapping Load ProductID, NUM(SalesPrice) Resident Products;

Can you post the full script?

Sure Fong, 

Here it is...

P.S.

This script is from the book Qlikview Advance Data Visualization.

I am running the script with a debugger now - will let you know if I get a solution

Hi Fong, 

I found the error: Table name in Peek function was incorrect:

FOR L = 1 to $(vPCount)
//Calculate random values
LET vQty = Floor (Rand() * (50+ $(vDateFactor))) +1;
LET vRnd = Floor (Rand() * '$(vProdCount)');
LET vPID = Peek ('ProductID', '$(vRnd)', 'Product'); // The table name is Products
LET vCost = ApplyMap('Product_Cost_Map', '$(vPID)', 1);
LET vPrice = ApplyMap('Product_Price_Map' ,'$(vPID)', 1);

The script did run without given any 'token' error but has created a Syn key on Product Id and Sales Price. 

If I rename these two fields, the Product table does not connect to the fact table (Order Header).

I have attached the table view for your reference.
