[Event Request][W1][Table][39][Purchase Line] OnBeforeUpdatePrepmtAmounts event added parameters

[MacekE]

Why do you need this change?

We have a logic on sales lines, that we can not mirror on purchase side, because events are missing parameters. Makes custom prepayment logic harder to handle.

Describe the request

I would just like to extend parameters in event, so it matches Sales Line equal event.
In procedure UpdatePrePaymentAmounts() on purchase line there is event OnBeforeUpdatePrepmtAmounts(Rec, PurchHeader, IsHandled);

OnBeforeUpdatePrepmtAmounts(Rec, PurchHeader, IsHandled);
to
OnBeforeUpdatePrepmtAmounts(Rec, PurchHeader, IsHandled, xRec, CurrFieldNo);

[IntegrationEvent(false, false)] local procedure OnBeforeUpdatePrepmtAmounts(var PurchaseLine: Record "Purchase Line"; PurchaseHeader: Record "Purchase Header"; var IsHandled: Boolean) begin end;
to
[IntegrationEvent(false, false)] local procedure OnBeforeUpdatePrepmtAmounts(var PurchaseLine: Record "Purchase Line"; PurchaseHeader: Record "Purchase Header"; var IsHandled: Boolean; xPurchaseLine: Record "Purchase Line"; FieldNo: Integer) begin end;
Internal work item: AB#625158

Hi @MacekE,

xRec Parameter Requires Detailed Justification

Your request includes adding an xPurchaseLine parameter (xRec) to the event. While we acknowledge that the equivalent Sales Line event already includes this parameter, we need more specific information about your use case:

Please provide:

1. How will xRec be used? Explain exactly what your subscriber will do with the previous record values.

2. Why is Rec insufficient? Why do you need access to both the current record (Rec) and the previous values (xRec)?

3. Why are previous values specifically needed? What specific fields or comparisons do you need to make between current and previous values?

4. Context understanding: The UpdatePrePaymentAmounts() procedure is called during validation triggers. Please confirm you understand how xRec behaves in this context and why you specifically need it.

Note: We can see that similar events in Purchase Line (e.g., OnBeforeUpdateAmounts) already use xRec parameters, which suggests your need has precedent. However, we still need you to document the specific justification for your scenario to ensure the right solution.

Once you provide this information, we can proceed with the implementation.

Hi @AleksandricMarko
For all 3, current implementation does not need xRec, FieldNo will suffice, as i need to know from what field it was called to correctly calculate values in Purchase Line.
I tried to mirror equivalent event on SalesLine.

✅ Analysis complete - approved for implementation

Implementation:

Add the FieldNo parameter to the existing OnBeforeUpdatePrepmtAmounts event in the UpdatePrePaymentAmounts() procedure of Table 39 "Purchase Line".

Location in UpdatePrePaymentAmounts() procedure:

OnBeforeUpdatePrepmtAmounts(Rec, PurchHeader, IsHandled, CurrFieldNo);  // <-- Add CurrFieldNo parameter
if IsHandled then
    exit;

Event Publisher (update the existing event signature):

[IntegrationEvent(false, false)]
local procedure OnBeforeUpdatePrepmtAmounts(var PurchaseLine: Record "Purchase Line"; PurchaseHeader: Record "Purchase Header"; var IsHandled: Boolean; FieldNo: Integer)
begin
end;
