Hello, 

I tested a model that I developed with a small data that I entered it manually and I got a results. When I wanted to run it with all the data I have, so I impored  the excel file and the program displayed this error "Please notify IBM" (As it shown in the attached figure) 


Does anyone know how can I solve it ?

Thank you in advance.
Regards,

Hi,

do you get the same error if you add

execute
{
cplex.threads=1;
}

in your model ?

can you attach your model and data so that other user could try ?

Hi,

Thank Alex for your response. 

I do not know the usefulness of this instruction but I tested it and I still have the same problem.
I have attatched the model and the data that I'm using. 


The problem that I can get a result by using those data (in the figure below) but when each time I try to import the excel file it doesn't work.

Hi,
many errors in your model.

For instance I would write

{int} I=...; // the SKU i of the program reference i
{int} J=...; //Different storage area
{int} J1=...;

because I and J are no scalar but sets

in the .dat you wrote

I from SheetRead(my_sheet,"'data'!B2:B187");

but the name of the tab in excel is not data but Sheet1

Let me attach the 3 updated files I managed to run.
