Handles complete reversal workflow including G/L entries, subsidiary ledgers, and VAT entries. - `ReverseBankAccLedgEntry(BankAccountLedgerEntry: Record "Bank Account Ledger Entry"; NewEntryNo: Integer; SourceCode: Code[10])`: Creates a reversal entry for a bank account ledger entry with opposite amounts and signs. Handles bank account transaction reversal and maintains proper audit trail. - `ReverseVAT(GLEntry: Record "G/L Entry"; SourceCode: Code[10])`: Reverses VAT entries associated with a G/L entry by creating offsetting VAT transactions. Handles VAT reversal logic including unrealized VAT and non-deductible VAT amounts. - `CheckDimComb(EntryNo: Integer; DimSetID: Integer; TableID1: Integer; AccNo1: Code[20]; TableID2: Integer; AccNo2: Code[20])`: Validates dimension combinations for reversal entries to ensure posting compliance. Checks both dimension set validity and dimension value posting restrictions. - `SetReversalDescription(RecVariant: Variant; var Description: Text[100])`: Sets the description for a reversal entry based on the configured reversal entry description. Retrieves description from corresponding reversal entry record for the source record. Plus 18 local procedures. ## Triggers OnRun ## Relations - runs on [Table 81 "Gen.
