example, i have data like this :
| Amount | Tunjangan | PTKP | PKP | Tax |
| 2933254 | 0 | 2025000 | 908253.5 | 54495.21 |
| 2933254 | 54495.21 | 2025000 | 962748.7 | 57764.92 |
| 2933254 | 57764.92 | 2025000 | 966018.4 | 57961.11 |
| 2933254 | 57961.11 | 2025000 | 966214.6 | 57972.88 |
| 2933254 | 57972.88 | 2025000 | 966226.4 | 57973.58 |
| 2933254 | 57973.58 | 2025000 | 966227.1 | 57973.62 |
| 2933254 | 57973.62 | 2025000 | 966227.1 | 57973.63 |
| 2933254 | 57973.63 | 2025000 | 966227.1 | 57973.63 |
Tunjangan = tax from the previous record
PKP= (amount + tunjangan) - PTKP
Tax= PKP * 0.06
so how to use looping "do .. while"
until Tunjangan=Tax (example the last row in the table above) and if tunjangan=tax then looping stops.
thank you and sorry for my language
warm regards
