How to display three months by prompt

Question

Hi,
I have a requirement in dashboard,
there is a prompt of month, if I select one month, there will show three months' data,
example, if I select '201108', it will display 201107,201108,201109,
If I use '+' or '-' in month calculation, it has a problem, like across two year, 201012,201101,201102.
So how can I realize this requirement?
thank you!

example, if I select '201108', it will display 201107,201108,201109,
If I use '+' or '-' in month calculation, it has a problem, like across two year, 201012,201101,201102.I know this is not straight forward but you need to think this in more logical way. I know you have acheived it till the point you are selecting either Jan or Dec month like 201112 OR 201101.
EG: SUPPOSE I HAVE SELECTED 201112
Here you need to create a MID report with 3 cols like CURR MTH, PRV MTH, NEXT MTH
In NEXT MTH apply logic like :
- Convert 'CURR MTH + 1' to CHAR
- EXTRACT 2 CHARS from RIGHT
- IF EXTRACT = 13 THEN CONCAT (EXTRACT 4 CHARS FROM LEFT --- convert to INT and add 1. This will give you 2012 and concat this with 01). Again change to INT
REPORT will give: 201112, 201201, 201111
EG: SUPPOSE I HAVE SELECTED 201101
In PRV MTH apply logic like :
- Convert 'CURR MTH -1' to CHAR
- EXTRACT 2 CHARS from RIGHT
- IF EXTRACT = 00 THEN CONCAT (EXTRACT 4 CHARS FROM LEFT --- convert to INT and minus 1. This will give you 2010 and concat this with 12). Again change to INT
REPORT will give: 201101, 201102, 201012
You just need to play with String and CAST function to get it done
Rest you know..Hope this helps
