From a04b65583e7ddae88db9aa4f823eebd60f00034e Mon Sep 17 00:00:00 2001 From: Nitesh Yadav Date: Thu, 3 Sep 2026 10:41:38 +0530 Subject: [PATCH] fix(closure): post interest for real at submission, not as a dry-run estimate Ticking "Close this account" used to only preview the payout: assemble the account, run the same postInterest domain call close() will, read the resulting balance, then roll the whole thing back (GET /preview/{id}). Nothing was ever credited until the manager approved, and the account's own Interest Posted / Interest Earned figures stayed stale in the meantime. Changed to actually post the interest at that moment (POST /post-interest/{id} and again in submit()), via SavingsAccountWritePlatformService#postInterest(SavingsAccount, boolean, LocalDate, boolean) -- the exact service method close() itself calls, not a new calculation. Not routed through the POSTINTEREST_SAVINGSACCOUNT command: that command ships maker-checker-enabled in base Fineract, and CommandSourceService#processCommand runs the handler first, then throws RollbackTransactionNotApprovedException from inside the @Transactional method -- which would silently roll back the very posting just made. Depends on the sibling SavingsAccount fix (double-posting across runs) -- without it, ticking the checkbox on one business day and having the manager approve on a later one re-slices posting periods and credits the overlapping days twice. Also: - Locks the closure date at submission (stored on the request row) and replays that same date at approve() instead of re-reading today's business date, so close()'s own postInterest(account, true, closedOnDate, false) slices identical periods, matches the amounts already posted at submission, and adds nothing -- the figure quoted to the member at submission is what gets paid out however long the request sits in the manager's queue. - Populates closing_amount/rounding_amount/cashier_disbursed_amount at submission time instead of leaving them null until approval, since the interest posting above already makes the real payout figure known then -- the manager's review screen no longer shows a blank amount for a PENDING request. --- .../api/ClerkClosureRequestApiResource.java | 218 ++++++++++-------- 1 file changed, 126 insertions(+), 92 deletions(-) diff --git a/fineract-provider/src/main/java/org/apache/fineract/portfolio/clerkwithdrawal/api/ClerkClosureRequestApiResource.java b/fineract-provider/src/main/java/org/apache/fineract/portfolio/clerkwithdrawal/api/ClerkClosureRequestApiResource.java index 4d3d6f201..5569a5834 100644 --- a/fineract-provider/src/main/java/org/apache/fineract/portfolio/clerkwithdrawal/api/ClerkClosureRequestApiResource.java +++ b/fineract-provider/src/main/java/org/apache/fineract/portfolio/clerkwithdrawal/api/ClerkClosureRequestApiResource.java @@ -37,7 +37,6 @@ import jakarta.ws.rs.WebApplicationException; import jakarta.ws.rs.core.MediaType; import jakarta.ws.rs.core.Response; import java.math.BigDecimal; -import java.math.MathContext; import java.math.RoundingMode; import java.sql.Date; import java.sql.Timestamp; @@ -45,6 +44,7 @@ import java.time.Instant; import java.time.LocalDate; import java.time.format.DateTimeFormatter; import java.util.ArrayList; +import java.util.LinkedHashMap; import java.util.List; import java.util.Map; import java.util.Optional; @@ -53,13 +53,12 @@ import org.apache.fineract.commands.domain.CommandWrapper; import org.apache.fineract.commands.service.CommandWrapperBuilder; import org.apache.fineract.commands.service.PortfolioCommandSourceWritePlatformService; import org.apache.fineract.infrastructure.core.data.CommandProcessingResult; -import org.apache.fineract.infrastructure.configuration.domain.ConfigurationDomainService; import org.apache.fineract.infrastructure.core.serialization.FromJsonHelper; import org.apache.fineract.infrastructure.core.service.DateUtils; import org.apache.fineract.infrastructure.security.service.PlatformSecurityContext; -import org.apache.fineract.organisation.monetary.domain.MoneyHelper; import org.apache.fineract.portfolio.savings.domain.SavingsAccount; import org.apache.fineract.portfolio.savings.domain.SavingsAccountAssembler; +import org.apache.fineract.portfolio.savings.service.SavingsAccountWritePlatformService; import org.apache.fineract.portfolio.voucher.service.VoucherLine; import org.apache.fineract.portfolio.voucher.service.VoucherService; import org.apache.fineract.useradministration.domain.AppUser; @@ -67,10 +66,7 @@ import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.stereotype.Component; -import org.springframework.transaction.PlatformTransactionManager; -import org.springframework.transaction.TransactionDefinition; import org.springframework.transaction.annotation.Transactional; -import org.springframework.transaction.support.TransactionTemplate; /** * Maker-checker Cash-only savings account closure.
