How to schedule the batch job
NOTE: Developer skill is required for this setup as we do not have the UI for scheduled processes yet.
Open the Developer Console, paste the code below, and execute
GatewaySettlementReconciliationBatch settlement = new GatewaySettlementReconciliationBatch();
String cronExp = '0 30 3 * * ?';
System.schedule('[PosiPay] Gateway Settlement Reconciliation', cronExp, settlement);
