Please show what your resulting data set should look like. It is not clear in what way "how may form numbers would come in the data set " would affect adding a single column called "date_Produced". What values should be assigned to that variable when added?

Hi ,

The new date set columns shoule be in the following order

Clm sx date form_1 form_2 to form_n Date_Produced

I tried using retain statement for ordering , later I realised that the form numbers may different (could be more sometimes ) , So how I can add Date_Produced column at the end of this data set ( Date_Produce column has the date of the report created (sysdate)

Without any information on where that variable is coming or anything I would guess at:

data nat_forms;
  set nat_forms;
  date_produced="01JAN2017"d;
run;

Concern about the order of columns in a data set should generally be a low priority. A vast majority of what you may do in SAS will no be affected by the order of the data. If you need columns in a specific order for use by another program after exporting data from SAS then use appropriate tools when writing the output to match. SAS is concerned about the variable name for almost everything.
