Hi Everyone this is the original database table
| Item_NO | Posting_date | EntryType | LocationCode | Quantity |
| I0013078 | 12-2-2013 | 4 | RW003 | -1 |
| I0013078 | 12-2-2013 | 4 | INTRNASIT | 1 |
| I0013077 | 12-2-2013 | 4 | RW003 | -1 |
| I0013077 | 12-2-2013 | 4 | RW003 | -1 |
| I0013079 | 12-2-2013 | 4 | INTRNASIT | 1 |
| I0013079 | 12-2-2013 | 4 | RW004 | -1 |
| I0013078 | 12-2-2013 | 4 | INTRNASIT | 2 |

The expected result table is as below
| Item_NO | Posting_date | EntryType | LocationCode | Quantity |
| I0013078 | 12-2-2013 | 4 | RW003 | -1 |
| I0013078 | 12-2-2013 | 4 | INTRNASIT | 0 |
| I0013077 | 12-2-2013 | 4 | RW003 | -1 |

| I0013079 | 12-2-2013 | 4 | INTRNASIT | -1 |
| I0013079 | 12-2-2013 | 4 | RW004 | -2 |
| I0013078 | 12-2-2013 | 4 | INTRNASIT | 0 |
| I0013078 | 12-2-2013 | 4 | RW004 | -2 |
