Drop down in Module pool program

Former Member — Tue, 18 Mar 2008 06:21:16 GMT

Hi,

I need to have a drop down input/output field. For that I have given a name like YHRTM_LEAVE-ATEXT in screen painter. Here YHRTM_LEAVE is table and ATEXT is a field. I have maintained the possible values in ATEXT domain to avail the drop down values.

In PAI, I need to access YHRTM_LEAVE-ATEXT . But only YHRTM_LEAVE value appears only while debugging.

Could anybody help me to achieve my requirement.

Thanks

jey

This is an alternative option to using Domain.

I use this method to customize the dropdown/listbox available to a field.

Here I retrieve from a custom table to fill the values, however, you can read DD07T to obtain the Domain Values.

This code retrieves a value from DD07T.


  SELECT SINGLE ddtext INTO p_value
    FROM dd07t
    WHERE domname = 'ZDROPTYPE'
      AND ddlanguage = sy-langu
      AND domvalue_l = p_key.
  IF sy-subrc NE 0.
    p_value = 'Undefined'.

This is different code to retrieve from custom table and display.


TYPE-POOLS             vrm.

DATA:   " Letter Name Restrict List
  rletname_field   TYPE vrm_id,
  rletname_result  TYPE STANDARD TABLE OF vrm_value,
  rletname_val     LIKE LINE OF rletname_result.

In the PBO routine


  REFRESH rletname_result.
  SELECT letterid letterdesc
    INTO TABLE rletname_result
    FROM zlmetext
    WHERE relid = base_relid
      AND appl  = base_appl.

* Field name to assign drop down values
  rletname_field = 'BASE_RLETTER'.
  CALL FUNCTION 'VRM_SET_VALUES'
       EXPORTING
            id              = rletname_field
            values          = rletname_result
       EXCEPTIONS
            id_illegal_name = 1
            OTHERS          = 2.

You must, in the screen painter attribute screen make the Dropdown option = Listbox.

Additionally, on the attribute screen on the Program tab, you must make the Value list (under Entry Help) = 'A'.

I got the drop down box refferred by a data dictionary table field. Its appearing very well. But the issue is that I am unable to access the value I selected.

For instance, say there is a table named TABLE1. It has two field; FIELD1 and FIELD2. FIELD1 is the key in this table. FIELD2 has got some value in Domain level. So I created a drop down field as TABLE1-FIELD2. I have got the drop down value from the table.

But the issue is when I access TABLE1-FIELD2 in PAI. It has no value.

Only TABLE1 has the codes I mentioned in Domain level. You could ask me then why don't you use it easily. But I could see the value only during debugging not in the program.

In the program I haven't defined TABLE1 anywhere. So I can't access the code. If I tried to define TBALE1, it says already you have defined.Its something strange.

It was not a table control. Its just a drop down field.

The dropdown process will only return the key of your table. You will need to READ TABLE table1 WITH KEY FIELD1 = (screen field name of dropdown). You will then have access to FIELD2 information.

Thanks for the input Paul. But it says Internal table is not defined. I like to highlight one thing here.

During debugging, I am able to see the value : (

When I tried to define as an internal table, it says you can't re-deinfe TABLE1-FIELD2 even though I defined lik

data: TABLE1 like standard table of TABLE1 with header line.
