Hi All,
I am using a table-control in module pool programing.
Fields are coming from MAKT table.
I am trrying to provide a functinality so that when choose
a material no using f4 help for MAKT-MATNR field
the corresponding value of MAKT-MAKTX should
appear itself in corresponding table-control field.
It's not happening right now.
How I can create that functionality??
Thanx in advance

Hi

F4 help for a field in module pool

Hello Experts,
I need to provide f4 help on field sales office(VKBUR) in my module pool program.
I have searched forums about it. but all forum contains either doc. no or customers etc.
these field are directly available on table, so very easy to find.
But for sales office, how can i provide f4 help. there is no straight entries in tables like for this company code this sales office.
so its getting difficult for me to provide help.
so if anybody know the solution plz help, and if anyone know table where all sales offices are stored, i will be thankful.
Thanks,
Amar

Hi amar_war,
use screen painter to edit the screen layout where the field VKBUR is on. Double click the field to get the details screen. Here you can attach a search help to the field.
H_TVBUR has no more parameters, it will display a list of al sales offices with description text
H_TVBVK will also show the sales group, if VKGRP is a screen field, it will restrict the result list automatically on matching VKGRP.
H_TVKBZ has also VKORG VTWEG SPART - it will take those values from screen if filled.
If you are not satisfied with the results, you can easily create your own search help using own selection method and own search help exits if required.
Try standard search help for standard field first.
You can create a copy of VKBUR as ZVKBUR and attach search help there, you can create your own screen structure and attach the search help there - 50 ways to get your search help...

Search help for screen fields in module pool

Hi All,
I have a screen in Module pool which has 3 input fields, each input field is attached to the same search help.
These fields are from ztable . I have created a search help USING these 3 fields. All the 3 fields are marked for IMPORT and EXPORT.
So whenever i click F4 on any of the above 3 fields, It will display search help popup and returns some rows...But the values are transfered back only for 1 fields ..i.e for the first field only .
I want that ...as soon as i select any of the row from Search hit list..all the 3 columns should get populated with corresponding fields from that row.
I require it this way as user wants to select based on * selection.Ex: as then every this related to that should be popped up.
Pls help ASAP

But i am getting the following error.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_ASSIGN_CAST_ILLEGAL_CAST', was
not caught in
procedure "F4IF_INT_TABLE_VALUE_REQUEST" "(FUNCTION)", nor was it propagated by
a RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
The error occurred at a statement of the form
   ASSIGN f TO <fs> CASTING.
   ASSIGN f TO <fs> CASTING TYPE t.
or
   ASSIGN f TO <fs> CASTING LIKE f1.
or
   at table statements with the addition
   ASSIGNING <fs> CASTING.
The following error causes are possible:
1. The type of field f or the target type determined by <fs>, t or f1
contains data references, object references, strings or internal tables
as components.
Could some one help me how to resolve this issue.
Thanks in advance.

How to get calender in f4 help for select options in module pool (URGENT)

Hi All,
how to get calender in f4 help for select options in module pool
Please help .
Thanx in advance,
amruta

Hi Amruta,
First of all, you can not create select-options directly in module pool.
For creating <b>select-option is dialog prog</b> follow these steps:
1. create your selection screen model as subscreen by:
SELECTION-SCREEN BEGIN OF SCREEN 2000 AS SUBSCREEN.
PARAMETRS: P_MATNR LIKE MARA-MATNR.
SELECT-OPTIONS: S_BISMAT FOR MARA-BISMAT.
SELECTION-SCREEN END OF SCREEN 2000.
2. create a screen ( example 100 ) in your module-pool dedicated for selection-screen. on this screen layout sketch a sub-screen name like subscree_2000.
3. write this bit of code in PBO and PAI of the screen 100;
CALL SUBSCREEN SUBSCREEN_2000.
4. include this code in PBO:
INCLUDING SY-REPID '2000'
6. write user_command of PAI, call screen which is going to executable after selection-screen.
5. create a transcation for this dialog module pool with screen 100.
6. execute this transaction and you can see it's behaving like cool with select-options.
After that in [bprocee on value-request]</b>, use F4_DATE for both from and to option field.
Hope it will solve the problem.

Why is there no standard search help for table-field T056U-VZSKZ?

Hi Experts,
A blessed day.
Table-Field T056U-VZSKZ (Control table for calculation of interest on arrears-Interest calculation indicator or account number) is being used to provide the entries for a screen-field of a standard transaction for Account Determination: Posting Specifications. However, this table-field T056U-VZSKZ does not have a standard search-help. I've looked for an OSS for this, but wasn't able to find one. Is there a reason why this T056U-VZSKZ does not have the standard search help when VZSKZ is it's key field?
Thanks.
Regards,
ianne

Hi Marco,
When you attach the search help make sure you also attach the export parameter of the search help to the name column. That is in the tab 'Further characteristics' we have to pass two value. The search help name should be typed in place of 'Parameters' and the export parameter of the search help should be typed in the place of 'Name'.
Please try this and post back the updations.
Thanking you,
Jerry

The music store is part of iTunes. That is why they are together on the menu. As many topics would offer the same advice for music in your library or music in the store, grouping them together makes sense in terms of reducing redundant entries.
Sorry you found it confusing. I, too, once found some things Apple a bit different. That was about two years ago when I bought my iBook. StarDeb is another recent switcher. And I feel confident in saying this: either of us would be more than happy to help you with anything that gets "lost in translation". We both know there is a learning curve when you move from the XP world to a more fruit-based view of things

Forcing to use F4 help for a field

Currently if we enter Partner Number or First name or Last name of a partner in Contacts, Employee and Service Group fields, and click on enter we are getting the relevent BP full name. This happens even if we enter Contact BP number in Employee field or Service group fields or vice-versa.
So to avoid this, we need to restrict the user to use F4 help instead of entering manually in those field.
Can somebody help me on this?
Edited by: DP on Jun 10, 2011 3:52 PM

Hi,
Hey one option is to educate the user to select the F4 help always.
By default u need to raise the popup when ever user navigates to the screen from the pop-up u need to set the value and make the field is display mode to prevent typing the value. the only option is to set the value from the pop-up.

How to provide F4 help for a field in table control

Hi Friends,
I have requirement like below.
1.Create one custom transaction code with header and item information.
2.In item level, we will be designed table control to enter/display the data.
3.Table controls first field will be material number and next DOT number (Material may have many DOT numbers) and so on.
4.First user will enter material number in the table controls first rows first field and go to DOT number field.
5.DOT number has drop down option. If user selects drop down box of DOT number, he gets all the DOT numbers available in database. User selects one DOT number and double clicks on it then it will be populated in DOT number field box.
But for point number 5, business wants like when ever user enters material number in table control first field then select DOT numbers drop down then they want to see the particular materials DOT numbers only in the drop down list for selection. Not all DOT numbers available in data base. Same thing should happen for all item lines in table control.
Please see below example.
Assume data base table has 10 DOT numbers. But material number has only 2 DOT numbers. When ever user enters material number in item level table control and selects DOT numbers drop down then it should show only 2 DOT numbers which are related to particular material number. Not all 10 DOT numbers.
Could you please suggest me, how can we achieve this?

Hello,

For POV
Input Help in Dialog Modules
You can call dialog modules in the POV event using the event keyword PROCESS ON VALUE-REQUEST.
PROCESS ON VALUE-REQUEST.
FIELD <f> MODULE <mod>.
After the PROCESS ON VALUE-REQUEST statement, you can only use the MODULE statement together with the FIELD statement. When the user chooses F4 for a field <f>, the system calls the module <mod> belonging to the FIELD <f> statement. If there is more than one FIELD statement for the same field <f>, only the first is executed. The module <mod> is defined in the ABAP program like a normal PAI module. However, the contents of the screen field <f> are not available, since it is not transported by the FIELD statement during the PROCESS ON HELP-REQUEST event. You can now program your own value lists in the module. However, this procedure is only recommended if it really is not possible to use a search help. Defining search helps is much easier than PROCESS ON VALUE-REQUEST, since the system takes over some of the standard operations, such as getting field contents from the screen. It also ensures that the F4 help has a uniform look and feel throughout the system. Furthermore, it means that you do not have to reassign input help to fields on each screen.
Despite the introduction of search helps (and search help exits), there are still cases in which you need to use parts of the standard F4 functions directly. In this case, there are some standard function modules that you can use in the POV event. They support search helps, as well as all other kinds of input help, and are responsible for data transport between the screen and the input help. These all have the prefix F4IF_. The most important are:
F4IF_FIELD_VALUE_REQUEST
Calls the input help of the ABAP Dictionary dynamically. You can pass the component names of a structure or database table of the ABAP Dictionary to the function module in the import parameters TABNAME and FIELDNAME. The function module starts the ABAP Dictionary input help for this component. All of the relevant screen fields are read. If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the users selection is returned to the corresponding field on the screen. If you specify the table parameter RETURN_TAB, the selection is returned into the table instead.
F4IF_INT_TABLE_VALUE_REQUEST
This function module displays a value list that you created in an ABAP program. The value list is passed to the function module as the table parameter VALUE_TAB. If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the users selection is returned to the corresponding field on the screen. If you specify the table parameter RETURN_TAB, the selection is returned into the table instead.
There are also two function modules - DYNP_VALUES_READ and DYNP_VALUES_UPDATE - that can read the values of screen fields and return values to them during the POV event. For further information, refer to the relevant function module documentation.

The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
MODULE INIT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
PROCESS ON VALUE-REQUEST.
FIELD CARRIER MODULE VALUE_CARRIER.
FIELD CONNECTION MODULE VALUE_CONNECTION.
When the user chooses input help for the individual fields, the following is displayed:
For the Airline field, the POV module VALUE_CARRIER is called. The function module F4IF_FIELD_VALUE_REQUEST displays the input help for the component CARRIER1 of the structure DEMOF4HELP from the ABAP Dictionary, namely the search help DEMOF4DE. The users selection is returned to the screen field CARRIER.
For the Flight number field, the POV module VALUE_CONNECTION is called. The function module DYNP_VALUE_READ transports the value of the screen field CARRIER into the program. The program then reads the corresponding values from the database table SPFLI into the internal table VALUES_TAB using a SELECT statement, and passes the internal table to F4IF_INT_TABLE_VALUE_REQUEST. This displays the internal table as input help, and places the users selection into the screen field CONNECTION.
For POH------------
Field Help
There are three ways of displaying field help for screen elements:
Data Element Documentation
If you place a field on the screen in the Screen Painter by copying a ABAP Dictionary field, the corresponding data element documentation from the ABAP Dictionary is automatically displayed when the user chooses field help (as long as the help has not been overridden in the screen flow logic).
For further information about creating data element documentation, refer to data elements.
Data Element Supplement Documentation
If the data element documentation is insufficient, you can expand it by writing a data element supplement
Data element supplement documentation contains the heading Definition, as well as the following others:
Use
Procedure
Examples
Dependencies
To create data element supplement documentation for a screen, choose Goto ® Documentation ® DE supplement doc. from the element list of the screen. A dialog box appears in which the system proposes a number as the identified for the data element supplement. You can then enter help texts for the above headings using the SAPscript editor.
Data element supplement documentation created in this way is program- and screen-specific. Any data element supplement documentation created in the ABAP Dictionary with the same number is overridden by the screen-specific documentation. You can link existing data element supplement documentation created in the ABAP Dictionary with a screen field by using the table THLPF. To do this, crate a new row in THLPF containing the following data: Program name, screen name, field name, and number of the data element supplement documentation.
To display data element supplement documentation, you must code the following screen flow logic in the POH event:
PROCESS ON HELP-REQUEST.
FIELD <f> [MODULE <mod>] WITH <num>.
After PROCESS ON HELP-REQUEST, you can only use FIELD statements. If there is no PROCESS ON HELP-REQUEST keyword in the flow logic of the screen, the data element documentation for the current field, or no help at all is displayed when the user chooses F1. Otherwise, the next FIELD statement containing the current field <f> is executed.
If there is screen-specific data element supplement documentation for the field <f>, you can display it by specifying its number <num>. The number <num> can be a literal or a variable. The variable must be declared and filled in the corresponding ABAP program.
You can fill the variables, for example, by calling the module <mod> before the help is displayed. However, the FIELD statement does not transport the contents of the screen field <f> to the ABAP program in the PROCESS ON HELP-REQUEST event.
For further information about data element supplement documentation, refer to Data Element Supplements.
Calling Help Texts from Dialog Modules
If data element supplement documentation is insufficient for your requirements, or you want to display help for program fields that you have not copied from the ABAP Dictionary, you can call dialog modules in the POH event:
PROCESS ON HELP-REQUEST.
FIELD <f> MODULE <mod>.
After the PROCESS ON HELP-REQUEST statement, you can only use the MODULE statement together with the FIELD statement. When the user chooses F1 for a field <f>, the system calls the module <mod> belonging to the FIELD <f> statement. If there is more than one FIELD statement for the same field <f>, only the first is executed. However, the contents of the screen field <f> are not available in the module <mod>, since it is not transported by the FIELD statement during the PROCESS ON HELP-REQUEST event. The field help should not be dependent on the user input.
The module <mod> is defined in the ABAP program like a normal PAI module. The processing logic of the module must ensure that adequate help is displayed for the field in question. Instead of calling an extra screen with text fields, you should use one of the following function modules to display a suitable SAPscript document:
HELP_OBJECT_SHOW_FOR_FIELD
This function module displays the data element documentation for components of any structure or database table from the ABAP Dictionary. You pass the name of the component and structure or table to the import parameters FIELD and TABLE.
HELP_OBJECT_SHOW
Use this function module to display any SAPscript document. You must pass the document class (for example, TX for general texts, DE for data element documentation) and the name of the document to the import parameters DOKCLASS and DOKNAME. For technical reasons, you must also pass an empty internal table with the line type TLINE to the tables parameter of the function module.
For further information about how to create SAPscript documents, refer to the Documentation of System Objects documentation.

The next screen (statically defined) for screen 100 is 100. It has the following layout:
The screen fields DEMOf1HELP-FIELD1 and DEMOF1HELP-FIELD2 from the ABAP Dictionary and the program fields FIELD3 and FIELD4 are assigned to the input fields. The pushbutton has the function code CANCEL with function type E.
The screen flow logic is as follows:
PROCESS BEFORE OUTPUT.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
PROCESS ON HELP-REQUEST.
FIELD DEMOF1HELP-FIELD2 MODULE F1_HELP_FIELD2 WITH VAR.
FIELD FIELD3 MODULE F1_HELP_FIELD3.
FIELD FIELD4 MODULE F1_HELP_FIELD4.
The components FIELD1 and FIELD2 of structure DEMOF1HELP both refer to the data element DEMOF1TYPE. This data element is documented, and also has two supplements with numbers 0100 and 0200.
The following field help is displayed:
When the user chooses F1 on the input field for DEMOF1HELP-FIELD1, the data element documentation for DEMOF1TYPE is displayed, since the field does not occur in the PROCESS ON HELP-REQUEST event.
If the user chooses F1 repeatedly for the input field DEMOF1HELP-FIELD2, the data element documentation is displayed, along with the supplement documentation for either 0100 or 0200 alternately. The variable VAR is filled in the dialog module F1_HELP_FIELD2.
When the user chooses F1 on the input field for FIELD3, the data element documentation for DEMOF1TYPE is displayed, since this is called in the dialog module F1_HELP_FIELD3 by the function module HELP_OBJECT_SHOW_FOR_FIELD.
When the user chooses F1 on the input field for FIELD4, the SAPscript documentation DEMO_FOR_F1_HELP is displayed, since this is called in the dialog module F1_HELP_FIELD4 by the function module HELP_OBJECT.

Search Help for a Field of a Table Control

I have designed a screen using 'Table Control' with fields like Date, BoxNo,Quantity etc. Kindly tell me how to go about providing a search help for the field 'BoxNo' of this table control so that the user is not required to scroll down the entire table/list for selecting a particular box no.
Thanx in advance,
Alok.

When you go to screen painer, in screen painter attributes window, there is an atribute called search help, fill it.
Another way is, after PAI put:
PROCESS ON VALUE-REQUEST.
FIELD box_no MODULE f1_help_box_no.
And gives logic in that module using FM F4IF_INT_TABLE_VALUE_REQUEST.
Regards.

F4 help for a field in item table in a view cluster

Hi All,
I have a view cluster with two tables. I should provide F4 help for field in item table based on the selected row of the header table.
F4 should have only values fetched based on the header table entry.
How can i achieve this. Please suggest.
Regards,
Kusuma K.

Hi amar_war,
use screen painter to edit the screen layout where the field VKBUR is on. Double click the field to get the details screen. Here you can attach a search help to the field.
H_TVBUR has no more parameters, it will display a list of al sales offices with description text
H_TVBVK will also show the sales group, if VKGRP is a screen field, it will restrict the result list automatically on matching VKGRP.
H_TVKBZ has also VKORG VTWEG SPART - it will take those values from screen if filled.
If you are not satisfied with the results, you can easily create your own search help using own selection method and own search help exits if required.
Try standard search help for standard field first.
You can create a copy of VKBUR as ZVKBUR and attach search help there, you can create your own screen structure and attach the search help there - 50 ways to get your search help...
Regards,
Clemens
