How to create OVS help for custom field in OIF?

Hi All,
I have a requirement where i need to add custom field and display F4 help. I have added the custom field but how to add OVS search help to field as i need to pull data from db tables based on certain creteria.
Please explain with steps.
Thanks,
Vimal

Hi James,
Thanks for reply.
I checked few things you mentioned and here are the findings:
1) Following is the code i have written it GET_DEFINITION
ls_descr_attr-name = 'ZZ_APPOINT_AUTH'.
ls_descr_attr-label_text = 'Appointing Authority'.
ls_descr_attr-ovs_name = 'ZCL_INC_BINF_CLAS_UI_FRM'.
APPEND ls_descr_attr TO et_field_description.
is this enugh to identify which field we want to make an OVS help? because suppose if don't implement all other pharses and only provide above code in Get_Defination then will it show me F4 icon atleast on field?
2) DDIC_SHLP_NAME field is blank. And there are no duplicate records.
3) I tried putting break point in HANDLE_PHASE0() and all other phases but debugger does not run while starting the application.So do we need to call these methods at some point or they are called automatically ?
Thanks for your help.And let me know of any other details required.
Thanks,
Vimal

How to assign search help for custom cost centre field in SRM 7.0

Hi Experts!!
We are currently working in SRM 7.0.As per our business requirement, in account assignment tab we need to use a custom
cost centre field (ZCOST_CENTRE) instead of standard cost centre field.It is observed that for standard cost centre field there is a standard web-dynpro search-help assigned where it will return the F4 search help values from backend.
Can any one of you please help me how can I assign the search-help for the custom cost centre field. Is there any FM to call the backend cost centre search help for custom field or any other way how can I achieve this?
Thanks in advance.
Regards,
Kalyani

kalyani,
i can see your requirement in below way..
as it just reads: you need to assign the standard cost center help to a z cost center field in component /SAPSRM/WDC_UI_DO_ACC.. which actually is fetched though the component /SAPSRM/WDC_UI_BACKEND_SH
so, if you see the component controller of SAPSRM/WDC_UI_DO_ACC you will see the component
USAGE_SH_F4 /SAPSRM/WDC_UI_BACKEND_SH
USAGE_SH_F4 /SAPSRM/WDC_UI_BACKEND_SH INTERFACECONTROLLER
so you can replicate the same functionality for your z field.
but can you clarify one thing.. why are you going for this z field in place of standard field ?

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

How to create a Tip for a field in a Descriptive Flex Field in Self Service ?
Example :
For Address
Each Address Line should have one Tip.
What should I do ?
Thanks,
John

Hi John,
It seems you have created Address Location DFF in self service in OA Framework.....
I have created a Address Location flex in OA Framework . It dipslays the segments properly but i dont want to display the segments if they dont have any value.
I only want to display segments with values . The segments with null values should not display at all...
i.e , if Address Line 2 value is null , it should not display Address Line 2..
If you have done this, pls let me know how to go abt it.

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,
Check this :-
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.
Input help in dialog modules

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.
