How to enhance F4 help for the field KUNNR

Hi All,
I have a requirement to create custom table with the fields kunnr auart prodh among these fields for the field KUNNR I want to enhance the F4 functionality when user entering the data into this custom table means i should restrict only kunnr values which falls under particular customer account group. How can overwrite the existing F4 functionality of the KUNNR for this custom table?
Thanks&Regards
Mahesh

Hi
U create ur own serach help using the searchelp option is se11 and create it based on ur requirement zand make it as elementary not as collective.
go to SE 11 and click on KUNNR and click on scrh Help puchbutton and assign ur search help and it will be assigned to the same.
If u want use already one then DEBI, C_KUNNR A_KUNNR
QVDM_KUN REKUNNRCN RE_KUNNR are there
these are collective serach helps and assign ur help to any of these.
kindly let me know if u need further help.
Thanks
Shiva

CLM How to add search-help for extension field(New Company Field) in MA.

Hi all,
Based on demand,I need to extend a new field(Company) in Master Agreement.
But I do not know how to add search-help for this field,just like User Accont page.
Anyone can help me ?thank you very muck.
Regards,
JackyCheng

Hello Jacky,
To combine all the answers above and have a topic-based reply please go through the below steps:
#1. Inactivate the current extension field Company (I see it is actually a String value and this is not what you want to have)
#2. Go to Setup -> System Setup -> Extension Reference Types
Check if you already have a Company reference type
If not, create a new Extension Reference Type for Class Company. Fill in all required information.
#3. Create a new Extension Attribute
Select Data Type: Object Reference
Now you can add the Company type as reference

Bogdan Toma

How to find table name for the fields from Standard Extractor in CRM system

How to find table name of fields from the standard extractor in CRM system ?
e.g. We use LBWE TCode in R/3 system to find table name for the field from Extractor VCSCL(e.g.).
Likewise is there any way to find table name for the fields from Standard extractor like 0CRM_LEAD_I.

Hi ,
Please find the link below for understanding BW CRM analysis.
http://help.sap.com/bp_biv135/html/bw.htm
activate the CRM DSs by scenario:
1) Activate the application component hierarchy (tcode RSA9). Changes made to the application component hierarchy in the CRM system can be transferred to the BW using the "Edit Application Component Hierarchy" (SBIW - Postprocessing of DataSources).
SAP Note 434886 must be implemented in CRM 3.0 before the application component hierarchy is activated.
2) Activate the Business Content DataSources (tcode RSA5).
Select/enter the application component and choose Execute (F8).
To compare the shipped and active versions, choose the 'Select Delta' pushbutton. If there is no active version of the DataSource, it is selected automatically.
To activate the shipped version, choose the 'Transfer DataSources' pushbutton.
3) Management of the versions of the BW-Adapter metadata (tcode BWA5). All DataSources are displayed that are managed by the BW Adapter.
As in transaction RSA5 (Service API Metadata Activation), the 'Select Delta' function can be used to select the inactive DataSources or compare shipped and active versions.
You can also go directly to the screen for maintaining DataSources that are managed by the BW Adapter.
The 'Compare Version' function makes a detailed comparison of the shipped and active versions.
All BW-Adapter metadata is considered when versions are compared:
Header information (Table SMOXHEAD)
Mapping information (Table SMOXRELP)
Global selection conditions (Table SMOXGSEL)
Attribute key fields (Table SMOXAFLD)
Hope this helps.

How to implement SEARCH HELP for input field in WDA

Hi All,
I am doing a tool for my team. in this tool there are 4 input fields to show different processes. I implemented the 4 input fields and also bind the respective tables to these fields successfully. Actually I want to filter the data between 2 fields . Means the data in the 2nd input field should be based on the 1st input field. Means when I'll select for example 'CHI' (code for CHINA) in the 1st input field the 2nd field meant for country name should show all country name with value 'CHINA'. But the problem is that all values related to each field are in different table with no foreign key relationship and also some combinations are in single table..
I have tried the import and export parameter method for search help but no luck till now.
Can anyone please suggest me how to implement this scenario..
Thanks in advance...
sekhar

Hi sekhar,
Your Requirement can be implemented by OVS(Object Value selector) This is the custom search help .So that you can define on what basis the value has to be fetched.
Look at the below link
http://wiki.sdn.sap.com/wiki/display/WDABAP/ABAPWDObjectValueSelector(OVS)
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/606288d6-04c6-2c10-b5ae-a240304c88ea?quicklink=index&overridelayout=true
You need to use the component WDR_OVS.
It has 3 phases
In phase 1
     You will fetch the value from input field to F4 help dialog box.
In phase 2
     You will generate the search results , in this phase look for the input value given in field 2 and accordingly generate search result for the field 3.
In phase 3
     The selected value will be returned to the original screen.

How to change search help for standard field in me51n.

hi frnds,
I want to change search help option for 'Advice code' field under Additional DFPS tab in me51n. But i dont know how to change or add search help for standard field. so plz help..
best regards,
sudip biswas

Hi Abhi,
Try using any one option:
Create a Search Help in SE11.
Now Goto SE11 -> Enter Ztable -> Select that field -> Click Search Help and try to assign the created Search help to that field in your Ztable explicitly
OR
Create a Zdata element in SE11.
In Data Element, under Further Characteristics tab, enter Name Parameters of Search Help.
Assign this data element to that field in ur Ztable.
OR
Create a Zdomain and maintain a Value Table or Fixed Values for it.
Assign this domain to that field in ur Ztable.

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?

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.

ENDMODULE.
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.
