[Custom Infotype] Maintaining field based on subtype

Question

Hi expert,
I want to create a new subtype to store an employee's test result
Data need to be maintained are:
1. Test_type -> Subtype field
2. Person_in_charge
3. Result
4. Date.
The problem which i have is:
the result field can only be filled with certain value and specific for a subtype.
e.g:
Subtype 1 can only has result: A, B, C.
subtype 2 can only has result: D, E, F.
It's basically similar like the one on infotype 22 education where certain certificate is only applicable based on its educational establishment.
So my question is, how do you achieve above objective?

Answer 1

You will need to create a mapping table for you subtype and the allowed result values.
In your screen flow logic under a process on value-request. You can generate the values for your field based on the subtype.
process on value-request.
  field p9xxx-zresult  module result_help.
Then in the module result_help:
module sub_code_help input.
*--- Select your allowed values from your mapping table
Into table_of_results
*---- And call the function for value help..
      call function 'F4IF_INT_TABLE_VALUE_REQUEST'
        exporting
          retfield        = 'ZRESULT_CODE'
          dynpprog        = sy-cprog
          dynpnr          = sy-dynnr
          dynprofield     = 'T_PXXX-SUB_CODE'
          value_org       = c_struc
        tables
          value_tab       = table_of_results
        exceptions
          parameter_error = 1
          no_values_found = 2
          others          = 3.
      if sy-subrc <> 0.
        message e000(38) with 'Unable to provide Value Help'(003).
      else.
