[Event Request] Table 11401 "CBG Statement Line" - OnValidateIdentificationOnBeforeCheckCurrency

[KateDovgalova]

Why do you need this change?

In 4PS Construct we need to extend check on "Currency Code" by allowing combination of empty currency code and LCY code. In order to do so we need to be able to skip standard check.
We also need to copy additional field value from CBGStatementLine to current line.

Describe the request

Dear ALAppExtensions team,

On behalf of 4PS I would like to request integration event 'OnValidateIdentificationOnBeforeCheckCurrency' to be added to trigger Identification - OnValidate in table 11401 "CBG Statement Line".

                    IsHandled := false; //new
                    OnValidateIdentificationOnBeforeCheckCurrency(PaymentHistLine, CBGStatement, Rec, CBGStatementLine, IsHandled); //new
                    if not IsHandled then //new
                        if CBGStatement.Currency <> PaymentHistLine."Currency Code" then
                            Error(Text1000006,
                              CBGStatement.Currency, PaymentHistLine."Currency Code");

    [IntegrationEvent(false, false)]
    local procedure OnValidateIdentificationOnBeforeCheckCurrency(PaymentHistLine: Record "Payment History Line"; CBGStatement: Record "CBG Statement"; var CBGStatementLine: Record "CBG Statement Line"; CBGStatementLine2: Record "CBG Statement Line"; var IsHandled: Boolean)
    begin
        //new
    end;

Hi KateDovgalova,

Thanks for submitting this extensibility request. To help us process it efficiently, please update the issue to include the required information.

📚 Extensibility Guidelines

Missing Information:

• Alternatives Evaluated: Please describe which existing events or extension patterns you evaluated for this scenario and why they are not sufficient.
• Performance Considerations: Please add a short note about expected execution frequency and why the proposed IsHandled event will not create unacceptable overhead.
• Data Sensitivity Review: Please confirm whether any sensitive data would be exposed through the requested event parameters.
• Multi-Extension Interaction: Please describe whether multiple subscribers could conflict when bypassing the standard currency check and how that risk is acceptable or mitigated.

Please update the issue with the missing details. We'll automatically re-analyze once updated.

Hi Marko Aleksandric (@AleksandricMarko)

1. Alternative is possible - we can use OnValidateIdentificationOnBeforeCheck event to implement the customization. This would mean copying all the code to the new procedure and losing MS support for the copied procedure so adding new event is preferable for changing this specific part of code.
2. Performance impact of customized code is low. For batch bank statement import scenarios the profile is comparable to any other OnBefore/OnAfter subscriber pattern.
3. Parameter "Payment History Line" and "CBG Statement Line" expose sensitive data, "CBG Statement" has lower sensitivity. Subscribers run under the calling session's permissions, so a subscriber cannot read fields the current user is not licensed or permitted to access.
4. Multi-subscriber risk (IsHandled overwrite, duplicate Error calls) is real but bounded. Alternative solution (event OnValidateIdentificationOnBeforeCheck) carries significantly higher risk for multiple subscribers because bypassing it means owning the entire identification flow.

Implementation:

Add a new IsHandled integration event in the Identification field OnValidate() trigger so extensions can override the currency mismatch check after PaymentHistLine, CBGStatement, the current line, and the copied source line are all available.

Location in Identification field OnValidate() trigger (before the currency mismatch error):

                    IsHandled := false;
                    OnValidateIdentificationOnBeforeCheckCurrency(PaymentHistLine, CBGStatement, Rec, CBGStatementLine, IsHandled);
                    if not IsHandled then
                        if CBGStatement.Currency <> PaymentHistLine."Currency Code" then
                            Error(Text1000006,
                              CBGStatement.Currency, PaymentHistLine."Currency Code");

Event Publisher (add at the end of the table with other events):

    [IntegrationEvent(false, false)]
    local procedure OnValidateIdentificationOnBeforeCheckCurrency(PaymentHistLine: Record "Payment History Line"; CBGStatement: Record "CBG Statement"; var CBGStatementLine: Record "CBG Statement Line"; CBGStatementLine2: Record "CBG Statement Line"; var IsHandled: Boolean)
    begin
    end;
