## Events published

- `OnBeforeInitForm(var DeferralHeader: Record "Deferral Header"; DisplayDeferralDocType: Enum "Deferral Document Type"; DisplayGenJnlTemplateName: Code[10]; DisplayGenJnlBatchName: Code[10]; DisplayDocumentType: Integer; DisplayDocumentNo: Code[20]; DisplayLineNo: Integer; var PostingDate: Date; var StartDateCalcMethod: Text; var IsHandled: Boolean)` (integration): Integration event raised before initializing the deferral schedule form. Enables custom form initialization logic or parameter modification.
- `OnOnQueryClosePageOnAfterCalcShowNoofPeriodsError(DeferralHeader: Record "Deferral Header"; DeferralLine: Record "Deferral Line"; var ShowNoofPeriodsError: Boolean)` (integration): Integration event raised after calculating whether to show number of periods error. Enables custom logic for determining period validation error display.
- `OnOnQueryClosePageOnAfterDeferralLineSetFilters(DeferralHeader: Record "Deferral Header"; var DeferralLine: Record "Deferral Line")` (integration): Integration event raised after setting filters on deferral lines during page close validation. Enables custom filter modification or additional processing on deferral lines.
- `OnOnQueryClosePageOnBeforeCheckEarliestPostingDate(DeferralHeader: Record "Deferral Header"; var DeferralLine: Record "Deferral Line"; var IsHandled: Boolean)` (integration)

## Procedures

- `SetParameter(DeferralDocType: Integer; GenJnlTemplateName: Code[10]; GenJnlBatchName: Code[10]; DocumentType: Integer; DocumentNo: Code[20]; LineNo: Integer)`: Sets the parameters that identify the source document line for which the deferral schedule is being created.
- `GetParameter(): Boolean`: Returns whether the deferral schedule has been modified by the user.
- `InitForm()`: Initializes the form by loading the deferral header record and setting up display fields. Retrieves posting date from the appropriate source document based on deferral type.

## 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: "page", object_name: "Deferral Schedule")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
