Hello GKR,
As I understand your internal table will have the records like this.
| Finished | Raw material | Open PO |
| FN1 | RM1 | 100001 |
| FN1 | RM1 | 100009 |
| FN1 | RM1 | 100011 |
| FN1 | RM1 | 100014 |
| FN1 | RM1 | 100018 |
| FN1 | RM2 | 100008 |
| FN1 | RM2 | 100007 |
| FN2 | RM3 | 100008 |
| FN2 | RM3 | 100012 |
| FN2 | RM1 | 100001 |
| FN2 | RM1 | 100009 |
| FN2 | RM1 | 100011 |
| FN2 | RM1 | 100014 |
| FN2 | RM1 | 100018 |
You can achieve this by using DELETE DUPLICATES FROM itab COMPARING raw material and Open PO.
The result table will have the records as per your expectation.

Thanga
