How can I lock the NumAtCard field in the marketing document screen

Question

Dear Experts,
Is there any way I can lock the marketing documents' (say Goods Receipt PO) BP Ref Number field? meaning if there are already values in the field, I do not want any users to change it.
Please help!
Warmest Regards,

Hi Chin,
There are two options to resolve your problem i.e. using DI SDK code and SP_TN.
if you want to to use SDK code, it requires big effort except you have a good programmer.
if you using SP_TN, you could use this following sample:
if @transaction_Type in ('A','U') and @object_type in ('20')
begin
        if exists (
                select a.DocEntry
                from OPDN a inner join OPDN b on a.numatcard=b.numatcard and
                                        a.DocEntry<>b.DocEntry
                where @object_type = '20' and (coalesce(a.numatcard,'')<>'' and (year(a.docdate) =
year(getdate()) and year(b.docdate) =year(getdate())))
                        and a.DocEntry = @list_of_cols_val_tab_del
        begin
                set @error = -1
                set @error_message = 'BP ref no. has been used'
        end
End
The above query SP is to block the use of last year BP ref no. I also have modified so that not only last year but even yesterday.
You can modify it by your own way.
