I have the following table:
Entry No. | Reference No. | Document No. |
1 | AAA |
2 | BBB |
3 | CCC |
4 | 1 | DDD |
5 | 2 | EEE |
6 | 3 | FFF |
7 | 4 | GGG |
8 | 7 | HHH |
Entry No. is a unique Number. Entry nos 1 to 3 are staring numbers, the balance are linked numbers,. for eg. entry no 8 is linked to 7 which in turn is linked to 4, which in turn is linked to 1. Because there is no reference against 1, it is the the starting number
i wanted the results as below:
Entry No. | Reference No. | Document No. |
8 | 1 | AAA |
For entry no. 8, the links end at entry no. 1 and corresponding reference against 1 is AAA.
i got the output as required in the attachment.
Now i have made a small change.
Entry No. | Reference No. | Document No. |
1 | AAA |
2 | BBB |
3 | CCC |
4 | 1 | DDD |
5 | 2 | EEE |
6 | 2 | FFF |
7 | 4 | GGG |
8 | 7 | HHH |
in the above table, for entry 5 and 6, the reference number is the same.
Now can anyone help me with this revised table.
