Runtime change of field text in module pool

Hi All,
I have a requirement where I have 2 fields in module pool. Based on input of first field the text of second field is decided. i.e. we have to change the text of second field based on value of first screen.
How to handle this.
Edited by: Suchender Dagar on Nov 24, 2010 5:38 AM

Hi,
Define a variable w_field(20) type c.
Put a input/output field in the second screen ( with the name w_field ) where you want the text and change the attribute of that field by removing the tick input checkbox and then selecting the 2D attribute of tat field, this will make the field as text field.
Then in PBO of the screen screen write the code based on the First field fill the text in the seconf field.

How to track changes to fields in a Module Pool Program

Hi Experts,
I have one requirement to track the changes to some fields used in the Program, The fields for tracking the changes will be maintained in a table T1, this will be changed dynamically.
There are many screens in the program and many fields in each screen.
1. How to do the coding for tracking the changes, the code should track all the changes to the fields maintained in the table T1.
Thanks in Advance.

Hi Baburaj,
The table logging concept will helpful for this requirement.(Tcode: scu3 --> give table name --> u can find changes for all fields).
Make use of concept change documents (auditing purpose used) --> CDHDR,CDPOS tables.
If you want to track changes to your own program, You need write some API to store the data.

Changing Field Labels of module pool screen dynamically

Hi All,
Can anybody tell me how to change field label of text field in dialog screen dynamically.
The Screen/Transaction is standard one.
I have created a Enhancement point for this change in one of PBO module's subroutine for this screen.
This Field label is defined as a 'Text' field only. We can't change it any more as it is standard one.
Can anybody tell me the solution for the same.
I have to change this label value as per some validations and its corresponding text field value will remain as is.
Thanks,
Deep.

Hello,
I think it is not possible, but try changing the name by Looping on screen table on PBO,
Bye

Hai ,
here you have to use custom control, for this
DATA: line(256) TYPE c,
      text_tab LIKE STANDARD TABLE OF line,
      field LIKE line.
1) Create custom control in your screen
2)   CREATE OBJECT: container EXPORTING container_name = 'TEXTEDIT',   "--> (this is custom control name in screen)
                   editor    EXPORTING parent = container.
3) CALL METHOD editor->get_text_as_stream "This method reads data from custom control , inserts into itab 'text_tab'
         IMPORTING
          text = text_tab.                                       "
      READ TABLE text_tab INTO line INDEX 1. read the text into wa 'line'
if you want more clarity , see 'ABAPDOCU' >ABAP USER DIALOGS>    COMPLEXSCREEN ELEMENTS--> DEMO CUSTOM_CONTROL

How to change the logon language in module pool program?

Hello All,
I had created a module pool program and had desiged a screen.
When i am logged in English language i am able to see them in english as per the requirement it is working fine.
But the requirement is wen i am logged in DE then the selection-screen texts should show in English and not in German.
Kindly give me a solution for this.
Thanks & Regards,
Rajesh Kumar

Hi Rajesh,
This problem is because you have maintained a standard dictionary fields on selection screen and all the standard dictionary fields are maintained in DE language, on the screen layout, go to the attributes of that particular text field, there is a option MODIFIZ for dictionary fields (it is a drop down), selection F TEXT, now whatever the text u will define, it will remain same for all the languages, once u do this then u again login in DE,l u will see the text maintained by u and not the DE text.
Do reply if problem still persist.
point if useful.

Field validation in Module Pool

Hi,
In my module pool, on main screen there are various fields, now out of these i've to give validation for 4 fields through a drop down field such that:
There are 2 items in my drop down, when 1st item of drop down is clicked then out of 4 fields for which i've to give validation, 2 should be Active (should take input) and other 2s should be inactive.
And if I click the 2nd item of dropdown then there shoud be vice versa(inactive ones should b active now and active ones should be inactive now).
Also got the function module VRM_SET_VALUES & a program DEMO_DYNPRO_DROPDOWN_LISTBOX for dropdown but don't know how can I use. If anybody can tell for either of or for both probs then will be a great help.

Hi,
As for the question regarding (de)activating fields:
parameters: pa_list ... "your listbox
data: st_first_two type i value 1,   "status of first two fields,
        st_last_two type i value 0.   "status of last two fields
at selection-screen.   "in PAI
"determine status of fields depending of what was choosen
if pa_list = '1st_item'.   "if first item picked
     st_first_two = 1.
     st_last_two = 0.
else.                           "2nd picked
     st_first_two = 0.
     st_last_two = 1.
endif.
"now change them
Loop at screen.
     if screen-name CS 'First_field' or
        screen-name CS 'Secodn_field'.
        screen-input = st_first_two.                  "(de)activate first two fields
    elseif screen-name CS 'Third_field' or
             screen-name CS 'Fourth field'.
         screen-input = st_last_two.                 "(de)activate last two fields
     endif.
    modify screen.
endloop.
This way you can in turn activate/deactivate your fields depending of the item picked in the listbox.
As for the question, this fm (VRM_SET_VALUES) is used to populate possible entires in the listbox in PBO (AT SELECTION-SCREEN OUTPUT) which user can later pick. It is usually used to fill data with your custom structure, not the DDIC one. Go through this demo and see step by step how data are populated to listobox (just before screen is displayed).
Also refer [this link|http://sap.niraj.tripod.com/id38.html]. It gives quite good explanation how it should be used.

How to deactivate the screen fields dynamically in Module Pool Program?

Hi guys,
 How to activate & deactivate the screen fields of a module pool program
dynamically through program. Like Change mode and display mode in a single
screen.

Hi,
Make use of a Variable,say gv_flag, for both Activate and Deactivate functionalities. As many times you hit the same button, change this variable value. For example, let us say first time you hit this button, assign value 'X' to this variable. Second time you hit this button, assign value ' ' to this variable. In PBO based the variable value you have to Activate and Deactivate.
PBO.
if gv_flag = 'X'. " Activate
 loop at screen.
 if screen-fname = 'ITAB1-MATNR'.
 screen-input = '1'.
 modify screen.
 endif.
 endloop.
elseif gv_flag = ' '. " Deactivate
 if screen-fname = 'ITAB1-MATNR'.
 screen-input = '0'.
 modify screen.
 endif.
 endloop.
endif.
PAI.
case sy-ucomm.
 when 'ACDC'. " Activate/Deactivate
 if gv_flag = 'X'.
 gv_flag = ' '.
 else.
 gv_flag = 'X'.
 endif.
endcase.

How to validate the field values in module pool program?

Hi Guys
 I am working with module pool programming.
 Here I want to validate the fields like below.
 with out filling all the fields if I click SAVE option it has to show a message that all fields has to be filled. This can be done by checking all the fields individually.
 I think it can be done through LOOP AT SCREEN ......ENDLOOP. sequence.
 If it is possible, can anyone help me?

You need to write the Module in between the CHAIN and ENDCHAIN statment in SE51
If you send a warning or error message from a module <mod> that you called using a FIELD statement as follows:
CHAIN.
FIELD: <f1>, <f 2>,...
MODULE <mod1>.
FIELD: <g1>, <g 2>,...
MODULE <mod2>.
ENDCHAIN.
all of the fields on the screen that belong to the processing chain (all of the fields listed in the field statements) are made ready for input again. Other fields are not ready for input. Whenever the MODULE statement appears within a processing chain, even if there is only one FIELD attached to it, all of the fields in the chain (not only the affected field) are made ready for input again, allowing the user to enter new values. If the fields in the processing chain are only checked once, the PAI processing continues directly after the FIELD statement, and the preceding modules are not called again.
Look at the DEMO program DEMO_DYNPRO_FIELD_CHAIN.

Custom field added in Module pool is not reflecting in SRM Shopping cart

Hi all,
I have to add a custom field for Plant in the Ship-To address subscreen(BBPSC01) in Shooping cart in SRM.
I have added the field in the program "saplbbp_sc_ui_its" in screen 310.
But I think need to write the HTML code/Java script in HTML template to trigger the code from module pool.
As I am new to this scenario, can anyone please let me know the procedure to follow.
Thanks,

Hello Anubhav,
If your new customer fields are not displayed dynamically, re-generate Dynpro concerned using report BBP_DYNPROS_GENERATE.

HOW to ADD F4 help to a field on SCREEN (MODULE POOL)

Hi,
     How to add f4 help to a field in screen ..plz help
Regards,
Saleha

Hi Saleha,
                In order to add F4 help to a field in modeule pool follow these steps:-
1. First go to SE11 and create your own search help( if you dont know how to create a search help please feel free to ask me, it is very easy).
2. Now in your module pool program program go to the layout of your screen.
3. Now when you see the attributes of this field in the Dict tab you will find the field Search Help. Now here you can specify the name of the search help you created in SE11.
There is also another mehtod to create the dynamic search help. eg:- in a posted document data get the Document nos related to that company code.
The sample code is like this:-
First of all declare the module below in the flow logic of your screen then create it in your main program.
You declare the module in the PROCESS ON VALUE-REQUEST.
PROCESS ON VALUE-REQUEST.
FIELD TXT_DOCNO MODULE VALUE_BELNR.
You also need to create an internal table where you wil store results of the select query fired below in the module.
here you will get a F4 help on the filed Document Number(TXT_DOCNO) based on the field Company code (TXT_CODCO)
MODULE VALUE_BELNR INPUT.
progname = sy-repid.
dynnum   = sy-dynnr.
CLEAR: field_value, dynpro_values.
field_value-fieldname = 'TXT_CODCO'.
APPEND field_value TO dynpro_values.
CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
    EXPORTING
      tabname     = 'BKPF'
      fieldname   = 'BUKRS'
      dynpprog    = progname
      dynpnr      = dynnum
      dynprofield = 'TXT_CODCO'.
CALL FUNCTION 'DYNP_VALUES_READ'
       EXPORTING
            dyname             = progname
            dynumb             = dynnum
            translate_to_upper = 'X'
       TABLES
            dynpfields         = dynpro_values.
READ TABLE dynpro_values INDEX 1 INTO field_value.
SELECT BUKRS BELNR
    FROM BKPF
    INTO CORRESPONDING FIELDS OF TABLE it_doc1
    WHERE BUKRS = field_value-fieldvalue.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            retfield    = 'BELNR'
            dynpprog    = progname
            dynpnr      = dynnum
            dynprofield = 'TXT_BELNR'
            value_org   = 'S'
       TABLES
            value_tab   = it_doc1.
ENDMODULE.                 " VALUE_BELNR INPUT
Hope you find this information useful, let me know.
