## Properties

| Property | Value |
|---|---|
| TableNo | Reversal Entry |

## Events published

- `OnBeforeGLRegPostingReportPrint(var ReportID: Integer; ReqWindow: Boolean; SystemPrinter: Boolean; var GLRegister: Record "G/L Register"; var Handled: Boolean)` (integration): Integration event raised before printing the G/L register posting report, allowing customization of report settings.
- `OnBeforeOnRun(var ReversalEntry: Record "Reversal Entry")` (integration): Integration event raised before starting the reversal posting process, allowing preprocessing of reversal entries.
- `OnRunOnBeforeDeleteAll(var ReversalEntry: Record "Reversal Entry"; Number: Integer)` (integration): Integration event raised before deleting reversal entries after successful posting.
- `OnRunOnAfterConfirm(var ReversalEntry: Record "Reversal Entry"; var Handled: Boolean; PrintRegister: Boolean; HideDialog: Boolean)` (integration): Integration event raised after user confirmation, allowing custom handling of the reversal process.
- `OnRunOnAfterCreateTxt(PrintRegister: Boolean; var Txt: Text[1024]; WarningText: Text[250])` (integration): Integration event raised after creating confirmation text, allowing customization of user messages.
- `OnRunOnBeforeCheckEntries(var ReversalEntry: Record "Reversal Entry")` (integration): Integration event raised before validating reversal entries, allowing custom pre-validation logic.

## Procedures

- `SetPrint(NewPrintRegister: Boolean)`: Sets whether to print the G/L register after posting reversal entries.
- `SetHideDialog(NewHideDialog: Boolean)`: Sets whether to hide confirmation dialogs during reversal posting.

## Triggers

OnRun

## Relations

- runs on [Table 179 "Reversal Entry"](../table/179.md)

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 17 "Gen. Jnl.-Post Reverse"](../codeunit/17.md) (1 call: `OnRun → Reverse`)

## Called by

- [Table 179 "Reversal Entry"](../table/179.md) (3 calls: `ReverseEntries → (object)`, `ReverseEntries → SetHideDialog`, `ReverseEntries → SetPrint`)
- [Page 183 "Reverse Transaction Entries"](../page/183.md) (2 calls: `Post → (object)`, `Post → SetPrint`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Reversal-Post")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
