Implementation of a user-defined, automatic order reconciliation

Introduction

Automatic order matching is an important part of document processing in Squeeze for Business Central. In the standard system, the system compares incoming documents with existing orders and goods receipts. This documentation shows you how you can extend this matching process to include your own document types.

The standard implementation uses a three-step process:

  1. Collect relevant document numbers based on business rules
  2. A detailed comparison is performed for each document number found.
  3. The positions read by Squeeze are then enriched with the data found.

We will retain this proven approach in the following example implementation.

Integration point

The central integration point is the OnBeforePerformAutomaticOrdermatch event in codeunit 70954632 “DXP SQZ Document Mgt.”. This event is called after header and line data has been created.

[IntegrationEvent(false, false)]
local procedure OnBeforePerformAutomaticOrdermatch(
    DocHeader: Record "DXP SQZ Document Header"; 
    var OrderNoList: List of [Code[20]]; 
    var IsHandled: Boolean)

Parameter

  • DocHeader: The document header with the data to be compared
  • OrderNoList: A list of document numbers for reconciliation
  • IsHandled: Controls whether standard processing should be skipped

Implementation example

Technical implementation

1. Extension of the document type enum

First, we extend the possible document types to include our own type:

enumextension 50100 "Custom Order Match Doc. Type" extends "DXP Order Match Document Type"
{
    value(50000; "Custom")
    {
        Caption = 'Custom Document';
    }
}

2. Implementation of the matching logic

The central point of our implementation is a code unit that controls the synchronization process. The integration point is:

//codeunit 50100 "Custom Document Matching"
//{
    [EventSubscriber(ObjectType::Codeunit, Codeunit::"DXP SQZ Document Mgt.", 'OnBeforePerformAutomaticOrdermatch', '', false, false)]
    local procedure OnBeforePerformAutomaticOrdermatch(
        DocHeader: Record "DXP SQZ Document Header";
        var OrderNoList: List of [Code[20]];
        var IsHandled: Boolean)
    var
        CustomSourceDoc: Record "Custom Source Document";
        CustomDocNo: Code[20];
    begin
        // Take control of the matching process and prevent standard processing
        IsHandled := true;
        
        // Find potential matching documents
        CustomSourceDoc.SetRange("Vendor No.", DocHeader."Buy-from Vendor No.");
        // Add your specific document status or type filters
        CustomSourceDoc.SetRange("Document Type", CustomSourceDoc."Document Type"::Order);
        CustomSourceDoc.SetRange(Status, CustomSourceDoc.Status::Released);
        
        // Add matching document numbers to the list
        if CustomSourceDoc.FindSet() then
            repeat
            	CustomDocNo := CustomSourceDoc."No.";
                if IsDocumentEligibleForMatching(CustomSourceDoc, DocHeader) then
                	if not OrderNoList.Contains(CustomDocNo) then
                    	OrderNoList.Add(CustomDocNo);
            until CustomSourceDoc.Next() = 0;

        // Process all collected documents
        ProcessMatchingDocuments(DocHeader, OrderNoList);
    end;

    local procedure IsDocumentEligibleForMatching(
        CustomSourceDoc: Record "Custom Source Document";
        DocHeader: Record "DXP SQZ Document Header"): Boolean
    begin
        // Implement business rules for document selection
        // For example:
        if CustomSourceDoc."Document Date" > DocHeader."Document Date" then
            exit(false);

        if CustomSourceDoc."Currency Code" <> DocHeader."Currency Code" then
            exit(false);

        // Check for open lines that can be matched
        if not HasOpenLinesToMatch(CustomSourceDoc) then
            exit(false);

        exit(true);
    end;

    local procedure HasOpenLinesToMatch(CustomSourceDoc: Record "Custom Source Document"): Boolean
    var
        CustomSourceLine: Record "Custom Source Line";
    begin
        CustomSourceLine.SetRange("Document No.", CustomSourceDoc."No.");
        CustomSourceLine.SetFilter("Outstanding Quantity", '>0');
        exit(not CustomSourceLine.IsEmpty());
    end;
//}

3. Processing of the documents found

After collecting the relevant document numbers, the actual comparison takes place:

local procedure ProcessMatchingDocuments(
    DocHeader: Record "DXP SQZ Document Header";
    OrderNoList: List of [Code[20]])
var
    TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary;
    OrderNo: Code[20];
begin
    foreach OrderNo in OrderNoList do begin
        // Get matching entries for current document
        GetMatchEntries(OrderNo, TempMatchEntry, DocHeader);
        
        if not TempMatchEntry.IsEmpty() then
            // Try to find and assign matching lines
            TryMatchDocumentLines(TempMatchEntry, DocHeader);
    end;
end;

local procedure GetMatchEntries(
    DocumentNo: Code[20];
    var TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary;
    DocHeader: Record "DXP SQZ Document Header")
var
    CustomSourceLine: Record "Custom Source Line";
begin
    TempMatchEntry.Reset();
    TempMatchEntry.DeleteAll();

    // Get lines from custom document
    CustomSourceLine.SetRange("Document No.", DocumentNo);
    
    if CustomSourceLine.FindSet() then
        repeat
            // Create match entry for each relevant line
            CreateMatchEntry(CustomSourceLine, TempMatchEntry);
        until CustomSourceLine.Next() = 0;
end;

local procedure CreateMatchEntry(
    CustomSourceLine: Record "Custom Source Line";
    var TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary)
begin
    TempMatchEntry.Init();
    TempMatchEntry."Document Type" := "DXP Order Match Document Type"::Custom;
    TempMatchEntry."Document No." := CustomSourceLine."Document No.";
    TempMatchEntry."Document Line No." := CustomSourceLine."Line No.";
    TempMatchEntry."No." := CustomSourceLine."Item No.";
    TempMatchEntry.Quantity := CustomSourceLine.Quantity;
    TempMatchEntry."Direct Unit Cost" := CustomSourceLine."Unit Price";
    TempMatchEntry."Line Amount" := CustomSourceLine.Amount;
    TempMatchEntry.Insert();
end;

The matching logic in detail

The actual reconciliation of document lines is performed according to defined business rules:

local procedure TryMatchDocumentLines(
    var TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary;
    DocHeader: Record "DXP SQZ Document Header")
var
    DocLine: Record "DXP SQZ Document Line";
    MatchSetup: Record "Custom Match Setup";
    HasCustomSetup: Boolean;
begin
    // Get configuration
    MatchSetup.Get();
    
    // Process each potential match entry
    if TempMatchEntry.FindSet() then
        repeat
            DocLine.Reset();
            DocLine.SetRange("Document No.", DocHeader."No.");
            DocLine.SetRange("Buy-from Vendor No.", TempMatchEntry."Buy-from Vendor No.");
            DocLine.SetFilter("Allocated Document Line No.", '%1', 0); // Only unallocated lines
            
            // Try matching strategies in order of precision
            if TryExactMatch(DocLine, TempMatchEntry) then
                CheckTolerancesAndAllocate(TempMatchEntry, DocLine, MatchSetup)
            else
                if TryItemReferenceMatch(DocLine, TempMatchEntry) then
                    CheckTolerancesAndAllocate(TempMatchEntry, DocLine, MatchSetup)
                else
                    if TryDescriptionMatch(DocLine, TempMatchEntry) then
                        CheckTolerancesAndAllocate(TempMatchEntry, DocLine, MatchSetup)
                    else
                        if TryBasicValuesMatch(DocLine, TempMatchEntry) then
                            CheckTolerancesAndAllocate(TempMatchEntry, DocLine, MatchSetup);
        until TempMatchEntry.Next() = 0;
end;

local procedure TryExactMatch(
    var DocLine: Record "DXP SQZ Document Line";
    TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary): Boolean

    DocLine.SetFilter("No.", '%1|%2', TempMatchEntry."No.", TempMatchEntry."Item Reference No.");

    DocLine.SetRange("Item Reference No.", TempMatchEntry."Item Reference No.");
    
    exit(not DocLine.IsEmpty());
end;

local procedure TryDescriptionMatch(
    var DocLine: Record "DXP SQZ Document Line";
    TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary): Boolean

    DocLine.SetRange("Item Reference No."); // Clear previous filter
    DocLine.SetFilter("SQZ Description", '@*' + TempMatchEntry.Description + '*');
    
    exit(not DocLine.IsEmpty());
end;

    exit(not DocLine.IsEmpty());
end;

local procedure CheckTolerancesAndAllocate(
    TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary;
    var DocLine: Record "DXP SQZ Document Line";
    MatchSetup: Record "Custom Match Setup")
begin
    DocLine.FindFirst();  // We know there is at least one line
    
    if IsMatchWithinTolerances(DocLine, TempMatchEntry, MatchSetup) then
        AssignMatchData(DocLine, TempMatchEntry);
end;

local procedure IsMatchWithinTolerances(
    DocLine: Record "DXP SQZ Document Line";
    TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary;
    MatchSetup: Record "Custom Match Setup"): Boolean
var
    QtyTolerance: Decimal;
    AmountTolerance: Decimal;
begin
    QtyTolerance := MatchSetup."Quantity Tolerance";
    AmountTolerance := MatchSetup."Amount Tolerance";
    
    if Abs(DocLine."SQZ Quantity" - TempMatchEntry.Quantity) > QtyTolerance then
        exit(false);
        
    if Abs(DocLine."SQZ Unit Price" - TempMatchEntry."Direct Unit Cost") > AmountTolerance then
        exit(false);
        
    exit(true);
end;

local procedure AssignMatchData(
    var DocLine: Record "DXP SQZ Document Line";
    TempMatchEntry: Record "DXP SQZ Order Match Entry" temporary)
begin
    // Assign the matched data to the document line

    DocLine.Modify(true);
end;
