Hi Shehzad,
SAPHELP on Advantages of ABAP Objects - Using ABAP - SAP Library says -
There are only two purposes for which procedural ABAP is essential:
· Encapsulation of classic screens in function modules.
· When you want to make functions available to other systems, but are not able to make class methods available externally using XI server proxies. In this case, you have to use function modules.

How to Call another screen using the ABAP Report which is displaying ALV ou

Hello All,
I am developing a ABAP report in which I want to transfer the stock from material to another material.
My Report will include 3 to screens.
The first sleection screen will display all the material with their stock value.
When we execute the report I will get the list of materials along with their current stock. On the top of the output screen I want the Execute button. Also , each line of the output should have checkbox or the ALV provides the functionality of editing one cell like that.....Once the user tick the checkbox or the cell....then I want to move to another screen where user can enter the Quantity and then user will tick ok and then I will call one function module so that the material documnet is posted and transfer of posting form material to material is done successfully.
Could anyone please help me out how to call another screen from the output screen where user can enter the Quantity amount....
I dont want to use the Dialog programming.....I want to create the simple ALV Abap report.
Regards,
Komal Bhutada.

Hi Raymond,
Thanks for the input...I will try this in my code .....
Can you please help me how to insert the checkbox in the ALV Output....so that I can select one of row and then press execute to process further?..
Thanks for the information.

How to call the screen in methods could u please explain

hi,
how to call the screen in methods could u please explain clearly with example

HI ,
CALL SCREEN - Call a screen
Basic form
CALL SCREEN scr.
Addition:
... STARTING AT x1 y1 ... ENDING AT x2 y2
Effect
Calls the screen scr; scr is the number of a screen of the main program. You use SET SCREEN 0. or LEAVE SCREEN. to define the return from the CALL screen.
Note
Please consult Data Area and Modularization Unit Organization documentation as well.
Addition
... STARTING AT x1 y1 ENDING AT x2 y2
Effect
The coordinates x1, y1 (start column and start line in the window) and x2, y2 (end column and end line in the window) define the size and position of the CALL screen ("top left - bottom right"). Besides these coordinates, you can also see the contents of the primary window, but cannot perform any action there.
Note
If "ENDING AT ..." is not specified, suitable values are substituted for x2 and y2, taking into account the size of the called screen.
Exceptions
Non-Catchable Exceptions
Cause: No further screen level (call screen); the maximum number of nested screen levels is restricted to 50 at present.
Runtime Error: DYNP_TOO_MANY_CALL_SCREENS

Call a function module inside of another function module

Has anyone ever called a function module inside of a remote enabled function module? Maybe this needs to be accomplished inside of an include. Just wondering.
Thanks!

Hi
No u can't do it because the RE_LAST_DAY_OF_MONTH is not remote function module.
If you need to call it u should insert it in a RFC, so u should create in R/3 a new RFC calling both fms: RE_LAST_DAY_OF_MONTH and the remote one.
And so call this new rfc instead of the other one.

Documentation of Function Modules and Class Methods

Hi
    I would like to know the function modules that handle the documentation of function modules and class methods.Is it possible to assign the same documentation of a function module to a method as method documentation?
    Are these documentations stored in some system tables?
Thanks in advance,
Hema

The documentation text is stored as Standard text.
you can see these details in the function module->
goto->documentation->
you will now see a screen, there GOTO->HEADER.
YOU will see a screen with the below details.
Text Name       Z0MM_SCM_FNC_EVCOR_DELIVERY
Language        EN
Text ID         FU   Function module
Text object     DOKU       Online Documentation
in this case TEXT NAME = FUNCTION MODULE NAME.
These details are stored in STXH &STXL . But you can use select from these tables. you have to use READ_TEXT to read the documentation to the program.

How to pass importing parameter of super class method to subclass method?

hi all,
i have defined a class
CLASS CUST_REPORT DEFINITION.
PUBLIC SECTION.
    METHODS:DATA_RETRIVE IMPORTING CUSTID_LOW TYPE ZCUSTOMER-ZCUSTID
                                   CUSTID_HIGH TYPE ZCUSTOMER-ZCUSTID.
    DATA:IT_CUST TYPE TABLE OF ZCUSTOMER,
         WA_CUST TYPE ZCUSTOMER.
ENDCLASS.                    "cust_report DEFINITION
The method DATA_RETRIVE   in this class has two importing parameters named CUSTID_LOW   and CUSTID_HIGH.
then i have defined subclas of this clas.
LASS CUST_ORD DEFINITION INHERITING FROM CUST_REPORT.
PUBLIC SECTION.
    DATA:IT_ORD TYPE TABLE OF ZORDER.
    METHODS:DATA_RETRIVE REDEFINITION,
           DISPLAY.
ENDCLASS.                    "cust_ord DEFINITION
Method DATA_RETRIVE   is redefined.
So how to pass importing parameteres of super class method to sub class method with the same name.
Thanks and Regards,
Arpita

Hi,
I tried like this.
METHOD DATA_RETRIVE.
CALL METHOD SUPER->DATA_RETRIVE
      EXPORTING
        CUSTID_LOW = I_CUSTLOW
        CUSTID_HIGH = I_CUSTHIGH.
ENDMETHOD.
But parameters I_CUSTLOW and I_CUSTHIGH are not getting values after call to method.
Thanks and Regards,

Ensure the module is loaded before calling the method in
particular if you are calling it at the initialization of your
app.

How to call a function module in VC

Hi,
I want to call a function module for an addition formula which shall calculate and infer the value.
eg. quantities of 5 different characteristics (of numeric data) is to be summed up and inferred against the 6th characteristic.
I want to know the detailed process to create a Variant Function and use it in a dependency.
Request to please advise the steps, type of dependency and its code.
Regards,
Rajesh Mohapatra

Dear Rajesh,
I also wanted to learn how to do that, your post motivated me to use a bit of freetime and investigate on the subject. I finally made my function work, so here are the tips.
The example is very simple, just a variant function with two inputs and which multiplies inside the input values and transfer that result to the output ( 3 x 4 => 12 ).
Deducting how to add five values or any other logic would be easier starting from there.
STEP 1: Create Variant Class for the product. I imagine you already have that. In my case its name is ZVC_CLASS, you have already a material assigned to the class, a configuration profile, etc....
STEP 2: Create Three Characteristics Z_NUM_CH_1,Z_NUM_CH_2,Z_NUM_CH_3 the three of numeric type
STEP 3: Assign characteristics from step 2 into class ZVC_CLASS
STEP 4: Create the function module with the code given below. I put the name ZVC_FUN_TEST
FUNCTION ZVC_FUN_TEST.
""Interfase local
*" IMPORTING
*" REFERENCE(GLOBALS) TYPE CUOV_00
*" TABLES
*" QUERY STRUCTURE CUOV_01
*" MATCH STRUCTURE CUOV_01

DATA:
GV_VALOR_FINAL TYPE CUOV_01-ATFLV,
GV_VALOR_NUM1 TYPE CUOV_01-ATFLV,
GV_VALOR_NUM2 TYPE CUOV_01-ATFLV.
CLEAR:
 gv_valor_final,
 gv_valor_num1,
 gv_valor_num2.
CALL FUNCTION 'CUOV_GET_FUNCTION_ARGUMENT'
 EXPORTING
 ARGUMENT = 'Z_NUM_CH_1'
 IMPORTING
 VTYPE = P_VTYPE1
 SYM_VAL = P_VALOR_SYM1
 NUM_VAL = gv_valor_num1
IO_FLAG =
 TABLES
 QUERY = QUERY
 EXCEPTIONS
 ARG_NOT_FOUND = 01.
IF SY-SUBRC <> 0.
 RAISE INTERNAL_ERROR.
ENDIF.
CALL FUNCTION 'CUOV_GET_FUNCTION_ARGUMENT'
 EXPORTING
 ARGUMENT = 'Z_NUM_CH_2'
 IMPORTING
 VTYPE = P_VTYPE1
 SYM_VAL = P_VALOR_SYM1
 NUM_VAL = gv_valor_num2
IO_FLAG =
 TABLES
 QUERY = QUERY
 EXCEPTIONS
 ARG_NOT_FOUND = 01.
IF SY-SUBRC <> 0.
 RAISE INTERNAL_ERROR.
ENDIF.
*- Calculate final value
gv_valor_final = gv_valor_num1 * gv_valor_num2. "Especifico de c/u.
DATA: VTYPE TYPE CUOV_01-ATFOR.
VTYPE = 'NUM'.
CALL FUNCTION 'CUOV_SET_FUNCTION_ARGUMENT'

 ARGUMENT = 'Z_NUM_CH_3'
 VTYPE = VTYPE
 NUM_VAL = gv_valor_final
 TABLES
 MATCH = MATCH
 EXCEPTIONS
 EXISTING_VALUE_REPLACED = 01.
IF SY-SUBRC <> 0.
 RAISE INTERNAL_ERROR.
ENDIF.
ENDFUNCTION.
STEP 5: Activate the function module for Variant Configuration in transaction CU65, put there your function module, release int and in button characteristics write Z_NUM_CH_1,Z_NUM_CH_2,Z_NUM_CH_3. Flag the first two lines as they are inputs.
STEP 6: Create a Dependency ZVC_PROC_TEST of type Procedure to call the function with this code:
000010 Function ZVC_FUN_TEST
000020 (Z_NUM_CH_1 = $root.Z_NUM_CH_1,
000030 Z_NUM_CH_2 = $root.Z_NUM_CH_2,
000040 Z_NUM_CH_3 = $self.Z_NUM_CH_3)
STEP 7: Lets say I want to calculate the multiplication only upon the selection of another characteristic "Calculate" YES/NO. For this I create a characteristic in CT04 Z_CALCULATE type CHAR 1 with possible values Y or N. For the value Y y add the procedure ZVC_PROC_TEST so that formula only activates on Y.
STEP 8: Add characteristic Z_CALCULATE to class ZVC_CLASS
STEP 9: VA01, it should work

How to call a function module from a transformation

Hi,
Could somebody please let me know how I can call an abap function module from a transformation (abap xslt program). I know how to call the class methods from transformation, but how do i call a function module..?
Thanks,
Shashi.
Edited by: Shashi Kanth Kasam on Apr 8, 2010 12:45 PM

Ya. I can do that. But I don't want to use a class and a method to call that function module. Want to directly call function module from transformation. Is that possible..?
Thanks,

How to call custom Login Module from JSP

Hi,
I am stuck with the following issue:
1) Exactly as presented in help.sap.com (http://help.sap.com/saphelp_nw04/helpdata/en/3f/1be040e136742ae10000000a155106/content.htm) I created custom login module and deployed it as a library on J2EE server. When I configured it to be used for my applications in the Security provider but I am getting "No user name provided" exception everytime when my applications use this custom login module.
2) I realized that I would need to call my custom module somewhere within my application (simple JSP) using LoginContext class and then use MyLoginContext.login() spec to initiate login process. But I am not able to pass CallbackHandler parameters from JSP application to my custom login module.
So I have the following questions:
1. Can I pass parameters using LoginContext and CallbackHandler from JSP to my custom login module (created as exact copy of HELP.SAP.COM example) or this module cannot be used this way.
2. How to pass CallbackHandler correctly to my custom login module from JSP. When I am trying to use CallbackHandler, I am getting "Abstract Class cannot be called" error.
I'd appreciate any little help on this matter.
Thanks and regards,
Mike

You have two alternatives to do this:
You can declare your JSP as a protected resource with the use of the deployment descriptors of the application (web.xml) and add the custom login module in the authentication stack of the application. This way, you will use container-based authentication, i.e. the Web Container will enforce the authentication and it will call the custom login module before it dispatches to the JSP. I recommend you this approach because it requires less coding and it makes the whole thing a matter of configuration. The configuration can be later on enhanced or changed runtime without the need to re-build and re-deploy the application. If you choose this approach you can go to the documentation of the server for help on how to modify the login module stack of the application.
You can also use programmatic authentication by using JAAS API. To do this you need to create a custom security policy configuration with login module stack containing the custom login module, and then use the standard JAAS mechanism - new LoginContext(<configuration>, <callback-handler>).login(). This approach requires that you write your own callback handler and handle any LoginException.
Let us know which approach you prefer and whether you have difficulties implementing it!

How to call a function module dynamically?

Hi
I am doing a smartform development and here my scenario.
Scenario:
There will be a simple report which will trigger a smartform output. The report has a selection screen and and in one of the field the user will enter the layout name or the layout name will be stored in the variant so that the user need not remember the layout name.
Based on the layout selected i need to show the output.
What i have coded:
In my program after selecting the data i am calling the FM SSF_FUNCTION_MODULE_NAME which will return the function module name to be called.
Question:
How do i call the function module dynamically. I cannot do a single call to the function module using the FM name derived from the above function call. I want to make the interface calling dynamic. We dont want to hardcode the function calls coz we may have many layouts to be called so how is it possible in SAP to call the FM interface dynamically.
~Suresh

Actually you can call the FM dynamically in by taking it into one variable and than use the CALL FUNCTION V_FM_NAME.
But the problem here is, you need to take care about the importing, exporting and tables parameters. They needs to be same for all FMs which you are planning to call. Otherwise system will give you a run time error.
 CALL FUNCTION 'SSF_FUNCTION_MODULE_NAME'
 EXPORTING FORMNAME = LF_FORMNAME
* variant = ' '
* direct_call = ' '
 IMPORTING FM_NAME = LF_FM_NAME
 EXCEPTIONS NO_FORM = 1
 NO_FUNCTION_MODULE = 2
 OTHERS = 3.
 CALL FUNCTION LF_FM_NAME
 EXPORTING
 ARCHIVE_INDEX = TOA_DARA
 ARCHIVE_PARAMETERS = ARC_PARAMS
 CONTROL_PARAMETERS = LS_CONTROL_PARAM
* mail_appl_obj =
* mail_recipient = ls_recipient
 MAIL_SENDER = LS_SENDER
