            loan.updateLoanRates(rateAssembler.fromParsedJson(command.parsedJson()));
        }

+        if (command.hasParameter(LoanProductConstants.ENABLE_DOWN_PAYMENT)) {


Please follow the same logic as it was done when loan was submitted:

You can disable down payment on loan, when the it was allowed on the loan product, but not the otherwise! It should fail with validation when not allowed action was tried:

user tries to enable down payment but it was not configured on loan product!
Ignoring the field silently that was sent is wrong!

Done! new validation method implemented in the LoanScheduleValidator

+        final boolean isDownPaymentEnabled = validateDownPaymentAttribute(loanProduct.getLoanProductRelatedDetail().isEnableDownPayment(),


Please move this into the loan validator!

Please move this into the loan validator!

+                loan.loanProduct().getLoanProductRelatedDetail().isEnableDownPayment(), command.parsedJson());
+        if (isDownPaymentEnabled != loanProductRelatedDetail.isEnableDownPayment()) {
+            changes.put(LoanProductConstants.ENABLE_DOWN_PAYMENT, isDownPaymentEnabled);
+            loanProductRelatedDetail.setEnableDownPayment(isDownPaymentEnabled);


Its more straightforward to set the values as "false" instead of assigning the value of the isDownPaymentEnabled which cannot be anything else but false.

We need to consider a couple of scenarios:

LP with DownPayment enabled and originally the LA with DownPayment enabled, then LA disable DownPayment, and
2.LP with DownPayment enabled and originally the LA with DownPayment disabled, then LA enable DownPayment

This is why we are validating If we have a change in the new value compared with the old value

You are checking the loan product configuration, but what you should check is only the configuration on loan. This method is covering the update loan application part, we already have something configured on the loan, thats the only thing that should be checked!

If on the loan product it was enabled down payment, but it was disabled when the loan was submitted and now when the loan is got updated, we want to enable again, you should not check what was set on the loan product, but check whether on the loan level what was set and now during the update if we wanna change it and enable again, then we can set from the loan product the down payment configurations on the loan level again.

+    private boolean validateDownPaymentAttribute(final boolean isDownPaymentEnabledInLoanProduct, final JsonElement element) {
+        boolean isDownPaymentEnabled = isDownPaymentEnabledInLoanProduct;
+        if (!isDownPaymentEnabledInLoanProduct) {
+            if (this.fromApiJsonHelper.parameterExists(LoanProductConstants.ENABLE_DOWN_PAYMENT, element)) {


This is wrong. We should only throw exception if the the down payment is disabled on the loan product (which is correctly checked) and when user tries to set down payment to be enabled during loan submission (this is the wrongly checked part)! If user provide enableDownPayment=false then nothing should happen: No violation!

Done! Logic updated

Please move the validations into the Validator class!

Done! moved to the validator

This change is unrelated. If this is a fix for something, please raise it in a new PR!

Done! removed, It belongs to an issue when you have a Loan Installment Fee

-        final boolean isDownPaymentEnabled = loanProduct.getLoanProductRelatedDetail().isEnableDownPayment();
+        final boolean isDownPaymentEnabled = loanScheduleValidator


Validations are called when loan got submitted or updated:
LoanApplicationWritePlatformServiceJpaRepositoryImpl.submitApplication
and
LoanApplicationWritePlatformServiceJpaRepositoryImpl.modifyApplication

Please move the validations into the loanApplicationValidator.validateForCreate and loanApplicationValidator.validateForModify

Done! All the validations are in the LoanScheduleValidator class

    }
+
+    public boolean validateDownPaymentAttribute(final boolean isDownPaymentEnabledInLoanProduct, final JsonElement element) {
+        boolean isDownPaymentEnabled = isDownPaymentEnabledInLoanProduct;


This method is overcomplicated:

public void validateDownPaymentAttribute(final boolean isDownPaymentEnabledInLoanProduct, final JsonElement element) { Boolean inputIsDownPaymentEnabled = this.fromApiJsonHelper.extractBooleanNamed(LoanProductConstants.ENABLE_DOWN_PAYMENT, element); if(!isDownPaymentEnabledInLoanProduct && Boolean.TRUE.equals(inputIsDownPaymentEnabled)) { throw new GeneralPlatformDomainRuleException("error.msg.downpayment.is.not.enabled.in.loan.product", "The Loan can not override the downpayment flag because in the Loan Product the downpayment is disabled", inputIsDownPaymentEnabled); } }

What do you think?

P.S.: You can consider passing the whole loan product as parameter and the validation method will decide what it is using from. Similarly the whole command passed as 2nd parameter

            loanProductRelatedDetail.setEqualAmortization(newValue);
        }
+
+        final boolean isDownPaymentEnabled = loanScheduleValidator


We only need the incoming isDownPaymentEnabled and if it is different than the one on the loan actually set then either set the LP config or reset it (based on we enable or disable it).

Done! In the LoanScheduleAssembler is only the input read If exists, else we set the LP value

+            loanProductRelatedDetail.setEnableAutoRepaymentForDownPayment(isDownPaymentEnabled);


Just because down payment was enabled, it does not mean auto repayment for down payment should be enabled as well. It should be set based on what was configured on the loan product

Done! We are just changing the enableDownPayment attribute
