Creating Record-Triggered Flow for Price Calculation
This section guides you to create your own flow and leverage the pricing engine for price calculations. The pricing engine is available as an apex action in the managed package. You can use this record-triggered flow to populate the pricing from SFS mobile app in the connected mode.
Perform the following steps to create a record-triggered flow that can be used to calculate the price for Product Consumed, Work Order Line Item, or Expense line items. The steps are explained for the Product Consumed line item as an example.
1. Log into your Salesforce org.
2. Create the apex class in the org as documented in the following code box. Include an InvocableMethod and a few InvocableVariables in the apex class that can be invoked from flows.
global with sharing class CalculatePrice {
@invocableMethod(label='Custom Calculate Price')
global static List<SVMXA360.CalculatePriceApexAction.PriceCalRequest> calculatePrice(List<SVMXA360.CalculatePriceApexAction.PriceCalRequest> lstInputParams) {
system.debug(LoggingLevel.INFO, 'calculatePrice() - enter.');
List<SVMXA360.CalculatePriceApexAction.PriceCalRequest> lstResponse = new List<SVMXA360.CalculatePriceApexAction.PriceCalRequest>();
try {
if (lstInputParams == null || lstInputParams.isEmpty()) {
//throw new SvmxSystem.SvmxNestedException(ErrorMessage.MISSING_REQUIRED_PARAMETER);
}
List<SObject> lstAllRecords = new List<SObject>();
for (SVMXA360.CalculatePriceApexAction.PriceCalRequest eachReq : SVMXA360.CalculatePriceApexAction.calculatePrice(lstInputParams)) {
if (eachReq.lstProductConsumedRecords != null && !eachReq.lstProductConsumedRecords.isEmpty()) {
lstAllRecords.addAll(eachReq.lstProductConsumedRecords);
for (SObject eachRecord : eachReq.lstProductConsumedRecords) {
SVMXA360.CalculatePriceApexAction.PriceCalRequest response = new SVMXA360.CalculatePriceApexAction.PriceCalRequest();
response.lstProductConsumedRecords = new List<SObject>();
response.lstProductConsumedRecords.add(eachRecord);
lstResponse.add(response);
}
}
if (eachReq.lstWOLIRecords != null && !eachReq.lstWOLIRecords.isEmpty()) {
lstAllRecords.addAll(eachReq.lstWOLIRecords);
for (SObject eachRecord : eachReq.lstWOLIRecords) {
SVMXA360.CalculatePriceApexAction.PriceCalRequest response = new SVMXA360.CalculatePriceApexAction.PriceCalRequest();
response.lstWOLIRecords = new List<SObject>();
response.lstWOLIRecords.add(eachRecord);
lstResponse.add(response);
}
}
if (eachReq.lstExpenseRecords != null && !eachReq.lstExpenseRecords.isEmpty()) {
lstAllRecords.addAll(eachReq.lstExpenseRecords);
for (SObject eachRecord : eachReq.lstExpenseRecords) {
SVMXA360.CalculatePriceApexAction.PriceCalRequest response = new SVMXA360.CalculatePriceApexAction.PriceCalRequest();
response.lstExpenseRecords = new List<SObject>();
response.lstExpenseRecords.add(eachRecord);
lstResponse.add(response);
}
}
}
if (lstInputParams[0].isUpdateRecords) {
Database.update(lstAllRecords);
}
} catch (DmlException ex) {
system.debug(LoggingLevel.INFO, 'calculatePrice(). Exception in updating source records: ' + ex);
throw ex;
}
catch (Exception ex) {
system.debug(LoggingLevel.INFO, 'calculatePrice(). Exception in price calculation: ' + ex);
throw ex;
}
system.debug(LoggingLevel.INFO, 'calculatePrice() - exit. lstResponse = ' + lstResponse);
return lstResponse;
}
}
