PAI Screen Fields

Dear Guys
I have created few screen Fields which save the data in table when some one click Save Button. Note down that these are screen fields not dictionary fields.
The problem is that when user press enter all fields gets cleared from screen. I have also tried to make those fields dictionary fields but the problem is still there whenever user press enter all value gets clear from the screen.
User dont want that value gets clear untill or less he will press save button.
Pls explain.
Thnx

Hi
Probably you're clearing those fields in PBO, you should consider when the user press enter the PBO is processed again.

[PAI] Refresh a screen field within PAI

Hi,
During the PAI process, I would like to refresh the content of a screen field (so that it is calculated automatically from the value of another field).
Indeed, the user would greatly benefit from this field condidering the checks performed during the PAI.
I tried the FM 'DYNP_VALUES_UPDATE' but without success...
Has someone another idea ?
Thanks in advance.
Best regards,
Guillaume

Hi,
Thanks for your insights !
I have 2 fields on the screen : my_source_field and my_pourcent.
Here is the code :
PROCESS AFTER INPUT.
MODULE exit AT EXIT-COMMAND.
CHAIN.
 FIELD my_source_field MODULE calculate_%.
ENDCHAIN.
CHAIN.
 ... lot of checks here, where the user requires the value of a % mininum
ENDCHAIN.
and in the calculate_% subroutine :
IF my_source_field <> 0.
 CLEAR my_pourcent.
 my_pourcent = ( k_%_mini * 100 ) / my_source_field.
* Updating screen immediately
 CLEAR : wt_update.
 REFRESH : wt_update.
 wt_update-fieldname = 'MY_SOURCE_FIELD'.
 wt_update-fieldvalue = my_source_field.
 APPEND wt_update.
 CALL FUNCTION 'DYNP_VALUES_UPDATE'
 EXPORTING
 dyname = sy-cprog
 dynumb = sy-dynnr
 tables
 dynpfields = wt_update
 EXCEPTIONS
 INVALID_ABAPWORKAREA = 1
 INVALID_DYNPROFIELD = 2
 INVALID_DYNPRONAME = 3
 INVALID_DYNPRONUMMER = 4
 INVALID_REQUEST = 5
 NO_FIELDDESCRIPTION = 6
 UNDEFIND_ERROR = 7
 OTHERS = 8.
 IF sy-subrc <> 0.
 ENDIF.
ENDIF.
Any idea ?
Best regards,

Populating the screen field when the cursor moves to that field

hi every one,
I want to populate the screen field(MODULE POOL) When the cursor moves to that field.
So can any one help me out with this.
EXAMPLE..
I want to populate 'S10_TOT_PRICE' (Total Price). When the fields like 'S10_PIECES' (Number of Pieces) will be entered. I want to populate 'S10_TOT_PRICE' without pressing any button on the screen nor when enter is hit. When the field 'S10_PIECES'' will be entered with some value and the cursor moves to 'S10_TOT_PRICE' . The Total Price field should be populated. Please help me out with this.
THANKS & REGARDS.
Mahanta.

Sorry but look at this SAP documentation <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/54/0608162d0711d295520000e8353423/frameset.htm">User Actions on Screens</a>
Extract :
User Actions on Screens
There are various ways in which users can interact with screens.
Filling Input Fields
Users can enter values in any input field on the screen, or change the value using the mouse, in the case of radio buttons and checkboxes. The contents are placed in the corresponding screen field. Filling an input field does not normally trigger the PAI event. Exceptions to this are Checkboxes and Radio Buttons with Function Codes and input fields with Drop Down Boxes.
So, i fear that you cannot "take hand" when user fill a numerical field to perform calculations and update the screen.

Holding the value in screen-field

Dear All,
I m facing the problem ,while i m putting the value in screen-field and then pressing enter,
value in that screen-field is becoming null automatically.
wht shld i do for holding the value even after PAI.
Thanks in advance.

Hi,
You should define a corresponding variable for that screen field in your program.
data: my_input_field type ... "same name and type as the one used in screen for field
so when you enter data to that field and press ENTER, the data will be transported to that variable and in PAI you have its value there.

RF Monitor - add screen field

Hi.
Is it possible to add a field in the report and how? or is there any user-exit?
Thx.

If your client/employer allows CORE-MODS then go ahead and make the changes just as you'd change any screen field. If not, I suggest you look at GUIXT. This comes standard as part of 4.6 and up ...
I suggest that you add this field (and necessary PBO/PAI logic) in custom tab and use GUIXT to display this field in whichever tab/screen you choose to.
You can go to GUIXT.com and check out sample code on how to do this. Its very simple, you should be able to go through the tutorial and do it yourself.

SCREEN field values

Dear Sir,
Can any body pls tell me how to pass screen field values generically in dialogue programming...the screen field values like input,output, group...
Can we use the table 'SCREEN' in dialogue programming..?? & how???
Regards,
Rushikesh

Hi Rushikesh,
What exactly is your requirement....?
You can use the table SCREEN for modifying the screen element attributes at runtime...
Suppose for example , when I click on a button, I want a button to be displayed...It can be done , but only in the PBO event....
Initially , go to the screen attributes and make it invisible...
Now in the program, you can do like this
1) Declare a global variable (say flag initialized to zero).
2) In PBO event
LOOP AT SCREEN.
IF SCREEN-NAME = 'FIELD1' and FLAG = 1.
screen-invisible = 0.
modify screen.
endif.
endloop.
3) In PAI event.
case sy-ucomm.
when 'CLICK'.
flag = 1.
endcase.
This is one example , you can have any number of situations.
Regards,
SP.

Screen field value under POV event

Hi All,
I have one issue...please suggest me solution for this.
In module-pool program i have one screen(1000) which has one field(hrname_1000).
Under this event:
PROCESS ON VALUE-REQUEST.
FIELD hrname_1000 MODULE hrname_1000.
under this module hename_1000 i have used F4IF_INT_TABLE_VALUE_REQUEST to put a search help for field hrname_1000.
after that i am trying to retrive HR related stuff's based on the field on module-pool i.e i am using hrname_1000 in the where condition.
but problem is that im not getting value for hrname_1000 which im giving in the module-pool screen.
thats y my select query is not working.
Where as im getting values for the hrname_1000 under PBO & PAI.
It will look like below.
PROCESS ON VALUE-REQUEST.
FIELD hrname_1000 MODULE hrname_1000.
(under the above module)
SELECT DISTINCT ename plans FROM pa0001 INTO CORRESPONDING FIELDS OF TABLE itab WHERE stell = '50001026'.
LOOP AT itab INTO wa WHERE ename = hrname_1000.
ENDLOOP.
Please suggest
Thanks & regards
Ansumesh

Hi,
I guess you don't get back value from function F4IF_INT_TABLE_VALUE_REQUEST to your global data object hrname_1000, althought it is returned from search help back to screen field.
See this thread. I explained there [how values are returned from screen field to a variable|https://www.sdn.sap.com/irj/scn/profile?userid=3509696]
You may also try with FM DYNP_VALUES_READ for reading dynpro fields values in POV.

In some of the cases the screen field is present in the screen but not holding the value in the required structure or field.
so here u need to check the option of reading the screen field values explictly..
//once u hit an enter and do the f4 i think the value will be there ...but if u dont hit enter and do an F4 the value cannot hold and i think u r in this case ..
1.Fill the screen field name in the structure dynpread.
DATA: BEGIN OF DYNP_VALUES OCCURS 10.
        INCLUDE STRUCTURE DYNPREAD.
DATA: END   OF DYNP_VALUES.
DYNP_VALUES-FIELDNAME = 'HRNAME_1000'.
APPEND DYNP_VALUES.
* read screen values
CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      DYNAME     = HELP_REPID "call the repid of ur prog
      DYNUMB     = HELP_DYNNR "pass the screen number
    TABLES
      DYNPFIELDS = DYNP_VALUES
    EXCEPTIONS
      OTHERS     = 1.
now dynp_values hold the field name and field value of the screen .
now
SORT DYNP_VALUES BY FIELDNAME.
    READ TABLE DYNP_VALUES WITH KEY 'HRNAME_1000' BINARY SEARCH.
    IF SY-SUBRC EQ 0.
      HELP_XXXX = DYNP_VALUES-FIELDVALUE. "store the value into a variable
      TRANSLATE HELP_XXXX TO UPPER CASE.
    ENDIF.
Now check the code with the value if its getting populated which once there will make ur select work ..

How to access screen field value in a module pool programming?

Hi Experts,
   I have create a module pool program SAPMYDLG. It contains two screens 100 and 200.
   The first screen contains Employee_ID field. This field is not a dictionary field.
   In the second screen 200, I want to access the value of Employee_ID field from first screen.
   For this I created a global variable v_empid in TOP include.
   Then in the PAI of the screen 100 I have assigned the screen field value to global variable.
   v_empid = Employee_ID.
   But this gives an error saying " Field Employee_ID not defined".
   What am I doing wrong? How can I access the screen field value?
Thanks
Gopal

Hi,
Employee_ID field also must u define in the top include when u define that 100 screen and 200 screen will access.

Module pool screen field should default without pressing enter

Hi
I have got a main module pool screen which has a tabstrip with four tabs.
There are 2 fields in the main screen when we select from F4 for the first field then the field 2 should default in case of a condition.
This happens only when i press enter. I want the second field to change as soon as the first field is selected.
How do I trigger the PAI as soon as the field 1 is selected.
eg:                           Field 1 : i/p
                                Field 2 : display
                               Field 3 : i/p
On F4 for field 1 say i select value 'A' then the valu for field 3 should default to value 'B'. Also field 2 should be displayed based on combination of field 1 and field 2. But now it does it only on pressing enter.
How do I solve this problem?Also if i select field 1 value A and dont press enter and go to the subscreen tab then it does not do any thing. It allows to go on the subscreen tab. But actually it should default the field 3 value. It does it only when I press enter.
Also the F4 is from dictionary that is the screen fields are from dictionary. I have not created any F4 for the fields.
Please help me solve this problem
Regards,
mozila

Hi
You can achieve this using List Box only not by Input Field. Since Input field doesn't trigger automatic PAI/PBO
Go through the below thread
populate drop down menu based on entry in another field
or an alternative is--> In PBO use POPUP_GET_VALUES Fm to get the First input field based on that you can enter further values

MB_MIGO_BADI - Not able to bring data to screen fields

Hi there,
I'm trying to add a new tab in the item level in the MIGO screen. In the new tab, I am placing a custom screen with some fields containing purchase order details. I am using the BADI MB_MIGO_BADI for this task. Now I'm able create a new tab and place the screen inside. But I'm not able to place bring the data to the screen fields in the new tab. I'm writing the code for including the screen in the method PBO_DETAIL. And this method do not have any parameters of purchase order details.
Have any one of you came across such situation??? If any one of can give a solution to work out this problem, it will be very helpful.

Under PAI method declare the field to u2018Xu2019.
Under the line modify method declare a flag and set to u2018Xu2019 checking for material document number by which we can set the fields to be in display mode when we open MIGO for display of material document created after doing goods receipt.
Under the POST_DOCUMENT method write the code for appending the value to Z table along with the values of the line item (In this case production order number, material, u2026u2026.). For these values to be available here in this method use the memory concept u201CExport to memory idu201D in the method LINE_MODIFY.
In order to do any validations to the custom fields, go to transaction SE80 and mention the program Name created and in PROCESS ON VALUE_REQUEST create a module and provide the validations required for those custom Fields.
In order to make the fields to be in display mode during the display of material document, create a module under PBO and import the flag value and the production order number details in the method LINE_MODIFY and if that flag = u2018Xu2019, use
LOOP AT SCREEN.
IF SCREEN-NAME = 'XXXXXX'.
SCREEN-INPUT = '0'.
MODIFY SCREEN.
ENDIF.
ENDLOOP.Retrieve the values from the Z table matching the key field (production order number) and pass the value of the custom field on to the screen.
Thanks,
Shailaja Ainala.

How to skip the mandatory field validation for clearing the screen fields

Hi Friends,
I have created a module pool screen, and made some fields mandatory. after entering some fields, if i try to clear the fields, am unable to clear. Its throwing the error "Enter all required fields"., since some mandatory fields are there. But i could able to navigate through other screen. Both the "CLEAR" and "NEXT" command are given in the at-exit command only. Next is working but clear is not working.
Please provide me the solution.
Thanks
Karthikeyan.L

Hi,
To avoid automatic input checks you have to assing function type - E to appropriate screen field, which is not to be checked.
These function codes don't trigger PAI processing, instead they go directly to
MODULE mod AT EXIT-COMMAND.
..placed in PAI of the screen. In this way you can ommit automatic checks performed by system on mandatory fields. Please ensure you have assing E type to next and clear functions in GUI status.

Marcin

Difference between At selection-screen and At selection-screen field

I need to know the difference between
Difference between At selection-screen and At selection-screen field
Regards
Shashi

Hi,
AT SELECTION-SCREEN is the event triggered in the PAI of the selection screen.
AT SELECTION-SCREEN on field field_name is the event specific to the field and is triggered when u press enter in that field.
AT SELECTION-SCREEN selscreen_event.
Effect
This statement defines event blocks for different events selscreen_event that are triggered by the ABAP runtime environment during selection screen processing.
Selection screen events occur immediately before sending a selection screen and after certain user actions on a displayed selection screen. They assist in selection screen processing in the ABAP program.
AT SELECTION-SCREEN is triggered at least twice during actions on selection screens that are linked into another selection screen as a subscreen - first for the linked selection screen itself, and then for the linking selection screens.
SELECTION-SCREEN FIELD SELECTION
FOR {NODE|TABLE} node [ID id].
Effect
This statement defines a node node in the structure of the logical database for field selection. If a node belongs to type T, you can use the TABLE addition instead of NODE. The statement cannot be used for type C nodes. .
If a node is defined for field selection, you can use an executable program linked to the logical database in the GET statement to control which fields in the node are to be read by the logical database. If you use the function module LDB_PROCESS, the FIELD_SELECTION parameter must be specified accordingly.
