Posted on by Community member 24
I have created a custom table and would like to attach documents to it.  I am using the code below.
But it when I attach the document it doesn't attach to the table and record, but rather just to table 0
 
IDLine No.Document TypeNo.Table IDAttachmentFile ExtensionFile Type
10Quote 0PO_CustomLayoutdocxWord
20Quote 0PO_CustomLayout2docxWord
 
        area(factboxes)
        {
            part(/Attached Documents/; /Document Attachment Factbox/)
            {
                ApplicationArea = All;
                Caption = 'Project Task Attachments';
                SubPageLink = /Table ID/ = const(50108),
                /No./ = field(/Task Name/);
            }
            systempart(Control1900383207; Links)
            {
                ApplicationArea = RecordLinks;
            }
            systempart(Control1905767507; Notes)
            {
                ApplicationArea = Notes;

    What is the Primary Key of Project Task table?
    Is this filter correct?
    /No./ = field(/Task Name/);
     
    Please check at the bottom of the blog about handling multiple fields in Primary key scenario if project task has multiple fields in primary key.

    Thanks Mohana,
     
    I added the codeunit please see below, but it didn't work.
    My custom table is Project Task
     
    codeunit 50154 DocumentAttachment
    {
        [EventSubscriber(ObjectType::Page, Page::"Document Attachment Factbox", 'OnBeforeDrillDown', '', false, false)]
     
        local procedure OnBeforeDrillDown(DocumentAttachment: Record "Document Attachment"; var RecRef: RecordRef);
        var
            ProjectTask: Record "Project Task";
        begin
            case DocumentAttachment."Table ID" of
                DATABASE::"Project Task":
                    begin
                        RecRef.Open(DATABASE::"Project Task");
                        if ProjectTask.Get(DocumentAttachment."No.") then
                            RecRef.GetTable(ProjectTask);
                    end;
     
            end;
        end;
     
        [EventSubscriber(ObjectType::Page, Page::"Document Attachment Details", 'OnAfterOpenForRecRef', '', false, false)]
        local procedure OnAfterOpenForRecRef(var DocumentAttachment: Record "Document Attachment"; var RecRef: RecordRef);
        var
            FieldRef: FieldRef;
            RecNo: Code[20];
        begin
            case RecRef.Number of
                DATABASE::"Project Task":
                    begin
                        FieldRef := RecRef.Field(1);
                        RecNo := FieldRef.Value;
                        DocumentAttachment.SetRange("No.", RecNo);
                    end;
            end;
        end;
     
        [EventSubscriber(ObjectType::Table, Database::"Document Attachment", 'OnAfterInitFieldsFromRecRef', '', false, false)]
        local procedure OnAfterInitFieldsFromRecRef(var DocumentAttachment: Record "Document Attachment"; var RecRef: RecordRef)
        var
            FieldRef: FieldRef;
            RecNo: Code[20];
        begin
            case RecRef.Number of
                DATABASE::"Project Task":
                    begin
                        FieldRef := RecRef.Field(1);
                        RecNo := FieldRef.Value;
                        DocumentAttachment.Validate("No.", RecNo);
                    end;
            end;
        end;
    }
