Function Module POPUP_GET_VALUES can be used to display a popup to get inputs from user. The specialty of this function module is we can add as many number of fields as we want. The fields can be of any data type.

REPORT ztestpopup.

DATA: t_fields LIKE sval OCCURS 0 WITH HEADER LINE.

START-OF-SELECTION.

Example Scenario

Now?  There was a business change and company code IN01 would no longer be used and will be replaced with IN02. The ABAP and BASIS teams are entrusted with the responsibility of creating new variants/change the existing variants.

How?  Automation can be achieved by the following piece of code:

The steps for Creating/Using Report category can be defined as follows:

1.  Create a program using the transaction SE38. 

Provide the logical database name as PNP. Click on SAVE. 

2. Then again follow this menu path—>GOTO—->ATTRIBUTES.

3. Click on the button HR report category to use the existing report category.

Select the radio button “Master Data (Infotypes)”.

Creating HR report category  

1. Click on HR report category

Give name of the HR report category to be create like ____0001(4 underscores 3 zeros 1) here follow the standards for creating the HR report category.  

To create new HR report category, click on new entries

Give the report category name   :  ____0002  (this is an example )

               Description                 : this is test report category        

Then save it under a transport request.

Click on allowable selection criteria—>choose enter—-> new entries.

Get the fields from select option field with F4 help and give the values to be appeared in the selection screen of the LDB you want.

Save it.  

Using Report Category in the LDB

If the report category is space, it means there is nothing given in the HR report category. 

The output screen will be like this…with more field options.

If the report category is

a) _____000 (5 underscores 3 zeros no gap) No LDB selection screen is displayed. It shows a clear screen. 

b) _____001 (5 underscores 2 zeros 1 no gap) only personnel number with out search help

c) _____003 (5 underscores 2 zeros 3 no gap) personnel number, Employment status,   Payroll area,Pers.area/subarea/cost center

Few sample programs:

1) Program for understanding the PNP LDB with report category _____001.

report zpnpldb .
INFOTYPES: 0001.
tables : pernr .
GET PERNR.
PROVIDE * FROM P0001 BETWEEN PN-BEGDA AND PN-ENDDA.
WRITE: / P0001-PERNR,
P0001-STELL,
P0001-BEGDA,
P0001-ENDDA.
ENDPROVIDE.
TABLES: PERNR.
INFOTYPES: 0001.
GET PERNR.
RP_PROVIDE_FROM_LAST P0001 SPACE PN-BEGDA PN-ENDDA .
IF PNP-SW-FOUND =  1.
WRITE: / PERNR-PERNR, P0001-STELL, PN-BEGDA, PN-ENDDA.
ELSE.
REJECT.
ENDIF.

2) This is a simple program for understanding the PNP LDB with report category space or with no report category.

report zpnpldb .
tables : pernr .
INFOTYPES: 2001 MODE N.
initialization .
*pnpbegda = sy-datum - 30 .
*pnpendda = sy-datum .
pnppernr-sign = 'I'.
pnppernr-option = 'EQ'  .
pnppernr-low = '1000'.
append pnppernr.
pnppernr-low = '1001'.
append pnppernr.
pnppernr-low = '1002'.
append pnppernr.
pnppernr-low = '1003'.
append pnppernr.
start-of-selection .
GET PERNR.
RP_READ_ALL_TIME_ITY PN-BEGDA PN-ENDDA.
LOOP AT P2001.
WRITE: / p2001-pernr , p2001-begda, p2001-endda, P2001-ABWTG.
ENDLOOP.
end-of-selection .

1] STATIC HELP ATTACHMENT

2] DYNAMIC HELP ATTACHMENT

1. Static Attachement

a) To a selection-screen element:

We can attach search help statically using Matchcode.

PARAMETERS p MATCHCODE OBJECT mobj.

b) To a Dynpro element:

Goto Layout -> Field Attributes -> Dict Tab – > Search Help Field. Specify the search help which you want to attach.

2. Dynamic Attachment

a) To a selection-screen element:

Following program shows the way to attach a search help dynamically.

REPORT z_test11 .

PARAMETERS: p_carrid(2).
DATA: table1 LIKE ddshretval OCCURS 0 WITH HEADER LINE.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_carrid.

CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
EXPORTING
tabname = 'scarr'
fieldname = 'carrid'
* SEARCHHELP = ' '
* SHLPPARAM = ' '
* DYNPPROG = ' '
* DYNPNR = ' '
* DYNPROFIELD = 'p_carrid'
* STEPL = 0
* VALUE = ' '
* MULTIPLE_CHOICE = ' '
* DISPLAY = ' '
* SUPPRESS_RECORDLIST = ' '
* CALLBACK_PROGRAM = ' '
* CALLBACK_FORM = ' '
* SELECTION_SCREEN = ' '
TABLES
return_tab = table1
EXCEPTIONS
field_not_found = 1
no_help_for_field = 2
inconsistent_help = 3
no_values_found = 4
OTHERS = 5
.
IF sy-subrc 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.

p_carrid = table1-fieldval.

START-OF-SELECTION.
WRITE: p_carrid.

b) To a Dynpro element:

 In PAI of the screen, call the event On alue Reuest.

PROCESS ON VALUE-REQUEST.

There are couple of functions for attching a search help to the fields displayed on the screen.

a) F4IF_FIELD_VALUE_REQUEST - F4 help for fields that are only known at runtime. The parameters it takes are: searchhelp,  shlpparam, dynpprog (program name), dynpnr (dynpro number), dynprofield(screen field to attach the help).

b) F4IF_INT_TABLE_VALUE_REQUEST - F4 help also returning the value to be displayed in internal table. retfield, dynpprog (program name), dynpnr (dynpro number), dynprofield(screen field to attach the help), value_org = ‘S’ (Structure),  Internal Table containing data to be displayed.

And if you want to attach domain values to the search help, you can just use SQL to get data for the domain (from table DD07V) and then calling function module F4IF_INT_TABLE_VALUE_REQUEST.
