hi

the external document number is not unique, you can associate it with multiple orders

so the solution that Mohana proposes is correct

This is done already on Purchase Orders, so You can check the validation of that field, and create the same for Sales Documents.

Make sure that once you posted the Order fully then the Order will be deleted and in that case the system will check External Doc No. in the existing Orders and not the already posted (deleted) orders.

If you want to check all existing and previous orders then use Customer Ledger Entries.

salesH.Reset;

SalesH.Setrange("Document Type", Rec."Document Type);

SalesH.Setfilter("No.",'<>%1',Rec."No.");

SalesH.SetRange("External Document No.", Rec.External Document No.);

if SalesH.findfirst then begin

Error('External Document No. %1 already used in document %2',Rec.External Document No.,SalesH."No.");

Please fix if there are any compilation issues as I just typed the logic here.
