I have two tables named 'Allrawmaterials' and 'Formulation',in 'Allrawmaterial' table there is field 'rawmaterial',if I update perticular value in field 'rawmaterial', it has to update filed 'raw' in table 'Formulation'.

  $objdpoddt = Formulation::LoadAll(QQ::OrderBy(QQN::Formulation()->ProductObject->Productnm));
foreach ($objdpoddt as $objdpodd){
                    
$objdpodd->Total= number_format($objformhasallrowmat->ProductionCost, 2, '.', '');
$objdpodd->BasicAmount= number_format((($objdpodd->Total*$objdpodd->Expence)/100)+$objdpodd->Total, 2, '.','');
$objdpodd->Save();
}

I had refreshed the database database,but the effect of changed data is seeing on all the 'rawmaterial' but iI have to update only perticular 'rawmaterial'which had updated in 'Allrawmaterials'.
