Hi,
You can pass the record reference to the Document Attachment page and then subscribe to the events for the document attachment to work with your table.
Action to open page:
var
DocumentAttachmentDetails: Page "Document Attachment Details";
RecRef: RecordRef;
begin
RecRef.GetTable(Rec);
DocumentAttachmentDetails.OpenForRecRef(RecRef);
DocumentAttachmentDetails.RunModal();
end;
Assuming single field Primary Key
[EventSubscriber(ObjectType::Table, Database::"Document Attachment", 'OnAfterInitFieldsFromRecRef', '', true, true)]
local procedure DocumentAttachment_OnAfterInitFieldsFromRecRef(var DocumentAttachment: Record "Document Attachment"; var RecRef: RecordRef)
var
FieldRef: FieldRef;
RecNo: Code[20];
begin
case RecRef.Number of
DATABASE::"Your Table":
begin
FieldRef := RecRef.Field(10);
RecNo := FieldRef.Value;
DocumentAttachment.Validate("No.", RecNo);
end;
end;
end;
[EventSubscriber(ObjectType::Page, Page::"Document Attachment Details", 'OnAfterOpenForRecRef', '', true, true)]
local procedure DocumentAttachmentDetails_OnAfterOpenForRecRef(var RecRef: RecordRef; var DocumentAttachment: Record "Document Attachment"; var FlowFieldsEditable: Boolean)
var
FieldRef: FieldRef;
RecNo: Code[20];
begin
case RecRef.Number of
DATABASE::"Your Table":
begin
FieldRef := RecRef.Field(10);
RecNo := FieldRef.Value;
DocumentAttachment.SetRange("No.", RecNo);
FlowFieldsEditable := true;
end;
end;
end;
