I have a dataset with the following structure:
| year |
Company 1 data A |
Company 1 data B |
Company 1 data C |
Company 2 data A |
Company 2 data B |
Company 2 data C |
Company 3 data A |
Company 3 data B |

I have around 1,000 different companies, each with 5 data points (3 in this simplified example).
I would like to make this a panel structure, as follows:
| year |
company |
Data A |
Data B |
Data C |
| 1 |
1 |
|
|
|
| 2 |
1 |
|
|
|
| 3 |

|
|
|
| 1 |
2 |
|
|
|
| 2 |
2 |
|
|
|
| 3 |
2 |
|
|
|
| 1 |
3 |
|
|
|
| ... |
|
|

I am aware of the reshape command. However, I do not see how I can use it in this context - if it is usable after all. In essence, I feel like I would neet to 'cut' the observations of each company and 'paste' them under those of the first, while creating a new variable that indicates which company is inserted, and repeating the 'year' values.
Many thanks for any potential help.
