st: How to solve "repeated time values" error message for panel dataset

[Nataliya Acc <p99asn01@yahoo.com>]

Dear Statalist users,

May I ask you one more question regarding declaring panel dataset panel or time series.
I know that it's very basic but these are my first steps with Stata. I keep getting an error and I do not know how to solve it. 

When I am trying to declare my dataset time series I keep getting the following error 
message:


within panel
r(451)


I have data 20 partner countries, each of which contains data on 16 industries for 11 years.

At the moment my dataset is organized in the following way:
1.)each partner country is codded from 1, 2, 3
... to 20.
2.) within each partner country data each out of 16 industries
are also coded from 1, 2... to 16)
3.) within each industry each out of 11-years periods are coded from
1.... to 11.

I would appreciate it so much if you could direct me on how I should recode it or what 
should I change to be able to declare my dataset time series.

Thank you

Best regards

Nataliya
