How to createWebservice from Functional Module inECC system and how to test

Hi all
i have one functional module in backend system i.e BAPI_GL_ACC_GETLIST. now i want to create a Webservice from the above functional module. once the webservice is ready in ECC system then how do we access in webdynpro thru model. i want to test the same webservice in ECC system itself, what is the procedure??
can any body send the clear steps on starting from create of webservice and till to access the same in webdynpro.
if we want to access from webdynpro thru model for the same webservice which did in ECC system, is it require to deploy on J2ee engine by creating the same webservice or we can access that directly in Webdynpro??
can you please tell me clear steps on the same rather than documents??
Regards

How can create a function module for currency and quantity fields

hi,
i want to create a function module with some fields.when i activated it give some errors for
netpr,menge,wemng fields(currency, quantity fields).error is it asks for reference fields.
please send me solution for it.
sreenu.

Hi Sreenu,
While creating CURRENCY/QUANTITY fields in the DataBase Table, you have to enter a REFERENCE TABLE and a REFERENCE FIELD to the field.
For that, after entering the field name and the data type in the correcponding columns, you have to place the cursor on the data type of the required field and click the CURRENCY/QUANTITY FIELDS tab. You will find two columns called REFERENCE TABLE and a REFERENCE FIELD.
you have to enter a reference table in which a currency/quantity field is used and a reference field which is a currency/quantity field in that table.
For Example, below is the table details.
FIELD DATATYPE LENGTH DEC.PLACES REF.TABLE REF.FIELD
1.SNO     CHAR 5
2.AMOUNT CURR 10     2          T001      WAERS
3.NOS     QUAN 5                 KNA1      /VSO/R_PAL_UL
Here Field 2(AMOUNT) is a CURR field whose Ref. Table is T001 and Ref. Field is WAERS and Field 3(NOS) is a QUAN field whose Ref. Table is KNA1 and Ref. Field is /VSO/R_PAL_UL.
Hope this will help you.

How to make this function module as RFC to get data from different system?

Hi
I am trying to use following function module . This function module is used to copy data from one cube to another cube within same system however I need a this should happen across two different system. How can I use this function module to make it remote call to different system and do the same function what it is doing ?
Name of function module -
RSDRT_INFOCUBE_DATA_COPY
Any help would be really helpful
AG

HI,
let us say you want to copy the data of a cube in system A to a cube in system B .
1) create a RFC function module in system B (in this function module call the function module RSDRI_CUBE_WRITE_PACKAGE to update the data), this RFC function module should have same parametersa as RSDRI_CUBE_WRITE_PACKAGE .
2) write a program in system A .. read the data from the infocube using the function module RSDRI_INFOPROV_READ and call the RFC function module in system B that you have created..
for the details of the parameters to pass to these two function modules use the RSDRT_INFOCUBE_DATA_COPY and get the required code
Thanks

How to create a generic datasource from function module?

Dear experts,
I have created a generic datasource from function module. For this extrator, I created a function module and a structure.
I have now some difficulties to continue:
In this function module, i get data from different transparent tables. Then i put these data into an internal table.
I just don't know what is the relatioin between the structure i defined and this internal table.
I should make "iTab structure AA" in the source code?
Thanks

3. SE37 ->Your Function module name -> Change , In table tab give your structure
name by deleting the associated type given in " XXXX " .
4. Now select source code and Do the coding . Give Data source name in Coding .
In your case you have to take data from more that 1 table .
5. Activate the Function Group .
6. In RSO2 Create the Data source , Give the Function Module Name , And Save.
7. RSA3 -> Give data source name and Check for the Records .
Creation of custom datasource. (Using function module)
.Create a function group .
. Structure ZTXXXX
Create function module (i.e. ZTESTXXX) .
. Create the data source using transaction (RSO2).
. If structure exists for the table parameter of your function module then ok else create a structure for the table parameter .
Test the datasource in R/3 using transaction RSA3.
Transfer the data source to BW System and replicate it in the BW-System.

ATP information
Functionality
Using this function module, you can determine the receipt quantity still available for a particular material in a certain plant according to ATP logic (MRPII).
The availability check is carried out on transferring the material number, the plant and the input table (WMDVSX). The scope of the check, that is, which stocks, receipts and issues are to be included in the check is defined by the combination of checking group (material master) and cheking rule. In the function module, the system uses the checking rule defined in Sales & Distribution (A). You can overrule this checking rule by using an interface or a user-exit (exit_saplw61v_001). A similar procedure is also valid for the plant parameters. The customer number in the user-exit means that the plant selection can be controlled via the customer. If no plant parameters are given via the interface, the system uses the parameter 'WRK' saved in the user's fixed values.
The results of the availability check are recorded in the output table (WMDVEX). This table contains dates and available receipt quantities (ATP quantities). The results of the check depends on the following entries:
If no date and no quantity is transferred, the system displays the ATP situation from today's date into the future as the result.
If only a date and no quantity is transferred, the system displays the ATP situation from the corresponding date as the result.
If both a date and a quantity are transferred, the system calculates the availability situation for the quantity specified.
In the last two cases, the parameter 'DIALOGFLAG' is supplied. This can result in the following:
' ' (blank)   <=> quantity completely available
'X'           <=> only partial quantity available or not available at
                  all
'N'           <=> Material not included in the availability check
                  (Material not relevant to the availability check)
The system also displays the end of the replenishment lead time (ENDLEADTME).

How to DEBUG a function module running in background mode? Please help!

Hi Experts,
   I am calling a function module in my ABAP code in background module using the following syntax:
CALL FUNCTION 'YBBC2_CREATE_SNAPSHOT' IN BACKGROUND TASK
          TABLES
            itab_std_format_inv = itab_std_format_inv
            itab_snapshot_inv = itab_snapshot_inv.
        COMMIT WORK.
If I put the breakpoint in the CALL FUNCTION line and execute the program, the debugger does not take me to the valled function module. This may be because I am running the function module as background task.
I cannot comment this "IN BACKGROUND TASK" statement as well since i am debugging in Quality system where I don't have change access.
So how to DEBUG a function module running in background mode? Please help!
Thanks
Gopal

Hi,
You could try to use the following trick:
(1) Put an endless loop into the coding of your function module where you want to start debugging, e.g.
DATA:
    lx_exit_loop(1)     TYPE c.
lx_exit_loop = ' '.
DO.
    IF ( lx_exit_loop = 'X' ).
      EXIT.
    ENDIF.
ENDDO.
(2) Call your function module in background task
(3) Call transaction SM50 and search for the background process.
(3) Choose from menu Program/Mode -> Program -> Debugging
Now you the debugger should bring you right to your endless loop. Set lx_loop_exit = 'X' in the debugger and continue (F5 or F6).

How many types of function modules are there

hi gurus,
how many types of function modules are there...
what type of function module bapi is....
i don't know much about that...
pls help me...
regards,
praveen

hi
hope it will help you.
<REMOVED BY MODERATOR>
Function Modules Used in Script:
In the Driver Program we must use all or some of the function modules that are listed below to transfer the data.
Open_Form
Close_Form
Start_Form
Write_Form
Write_Form_Lines
End_Form
Control_Form
Read_Form_elements
Read_Form_Lines
Any driver program must contain Open_Form, Close_Form and Write_Form. Other function modules are optional.
OPEN_FORM: This function module opens layout set printing. One must call this function module before he uses any of other layout set function modules like Write_Form, Start_Form, Control_Form etc., You need specify a layout set name in the export parameters of this function module. If nothing is passed to Open_Form then one should use Start_Form function module to open layout set before starting the output. The layout set opened by Open_Form should be closed by Close_Form function module, other wise output doesnt appear. We can use any number of Open_Form, Close_Form functions in one single program. But Close_Form must be there for every Open_Form in the program.
Some of the important export parameters we have to pass to Open_Form function module.
Form: Enter the Layout set name here, which then controls the output formatting. If nothing is specified then we must use Start_Form for opening layout set.
Language: Layout sets are Language dependent. Enter the desired language here. If the entered layout set is not in that language, then the function tries to open the Form entered in its original language. The default value is SY-LANGU.
Device: SAP Script can format a text on different device types. The device can be PRINTER or TELEX, TELEFAX, ABAP and SCREEN.
Dialog: Use parameter DIALOG to determine whether to display a dialog box before printing, in which the user can set several spool parameters for print formatting. Possible values: SPACE displays no print parameter screen. 'X' display print parameter screen. Default value: 'X'
Options: Use parameter OPTIONS to set several options for print formatting. The parameter has the structure ITCPO. The user can change some of the defined settings on the print control screen. The default value for Options is . We will discuss about ITCPO structure in detail later.
Other Export, Import and Exceptions are self-explanatory.
Close_Form: The function module closes the layout set opened using OPEN_FORM. The system executes any terminating processing steps for the last opened layout set. No Export parameters for this Function Module.
Start_Form: In-between the function modules OPEN_FORM and CLOSE_FORM, we can use different layout sets. This allows us to combine several different layout sets into one print output. However, we can combine only those layout sets that have the same page format. To switch layout sets, use the function module START_FORM. If another layout set is still open, we must close it first using END_FORM. If we specify no layout set name when calling START_FORM, the system restarts the last open layout set. If after OPEN_FORM no layout set was activated yet, the system leaves the function module with the exception UNUSED. Some of the important export parameters for this function module are
Form: The parameter contains the name of the layout set you want to use for printing. If you specify no layout set here, the system restarts the last active layout set.
Language: Layout sets are language-dependent. Enter the desired language here. If the layout set does not exist in this language, the system tries to call the layout set in its original language. If the parameter LANGUAGE is empty, the system uses the language of the last active layout set.
Startpage: Usually, SAP script starts with the page specified as start page in the layout set definition. If we want to start output with another layout set page, enter the name of the desired layout set page here. If the desired page is not defined, the system uses the start page defined in the layout set.
Program: To replace program symbols, SAP script must know which active program contains the work areas for the values to be passed. If we omit the parameter, the system searches for the field values in the program that was specified in the parameter OPTIONS (field TDPROGRAM) of OPEN_FORM. If we enter a program name, the system replaces the program symbols with the values from this program up to the next END_FORM.
Exceptions and other Export, Import parameters are self-explanatory.
Write_Form: The system outputs the layout set element specified in parameter ELEMENT into the currently opened layout set. In the parameter WINDOW we can specify the name of a window for the output. Remember that the layout set element must be defined in this window. The parameter FUNCTION specifies how to merge the text lines to be output with any existing contents in the window. In this case, there are differences between the different window types or areas. Some of the important export parameters used in Write_Form.
Element: Specify the name of the text element you want to output into the layout set window specified in the parameter WINDOW. The element must be defined in that layout set window. If you specify no element, the system uses the default element, if one is defined in the layout set.
Window: Specify the name of the window into which you want to output the layout set element specified in the parameter ELEMENT. Default value for Window is MAIN.
Function: The parameter determines how to output the text element into the respective window. The output type depends on the window type and area:
Window Type: MAIN Area: BODY
SET/APPEND: Appends to previous output.
Window Type: Main Area: Top/Bottom and
Window Type: Other than Main and all areas
SET : Delete the old element contents and prints the new elements
APPEND: Appends the new content to existing elements.
Type: The system interprets this parameter only for output to the main window. The parameter determines the area of the main window into which we want to output the element. Possible values: 'TOP' header area
'BODY' main area
'BOTTOM' footer area
Default value: 'BODY'
Write_Form_Lines: This function module outputs the text lines in table LINES into the specified layout set window. The text lines must have the SAP script ITF format. From the data in the text header, the system uses only the field TDSTYLE to apply the formatting attributes defined in the specified style for this text. If the field is empty, the system uses the identically named formatting attributes (character and paragraph formats) of the layout set.
Use parameter WINDOW to specify into which of the windows defined in the layout set we want to output the text. We can specify any window used in the layout set. The parameter FUNCTION determines how to merge the text lines to be output with any existing contents in the window. There are differences between the different window types or areas.
Header: This parameter contains the header of the text module we want to output in the current layout set. For the formatting process, the system uses only the entries in the header fields TDSTYLE and TDFORM. Structure: THEAD
WINDOW: Enter the name of the window into which we want to output the layout set element specified in parameter ELEMENT. Default value: 'MAIN'
FUNCTION: This parameter determines how to output the text element into the respective window. The output type depends on the window type and area: Window type MAIN, area BODY: 'SET' append to previous output 'APPEND' same as SET. DELETE' no effect. Window type MAIN, areas TOP and BOTTOM; all other windows: 'SET' delete old window or area contents and output the element 'APPEND' append the element to the existing elements 'DELETE' no effect Default value: 'SET'
TYPE: The system interprets this parameter only for output to the main window. The parameter determines the area of the main window into which you want to output the element. Possible values: 'TOP' header area 'BODY' main area 'BOTTOM' footer area Default value: 'BODY'
END_FORM: END_FORM ends the currently open layout set and executes the required termination processing. After calling this function module, no more layout set is active. For further output, we must start a new layout set using START_FORM. No Export parameters.
CONTROL_FORM: Use this function module to pass SAP Script Control Commands to the layout set. The Control command is passed through the export parameter COMMAND in quotes.
READ_FORM_ELEMENTS: This function module fills a table with all text elements that appear in one layout set. If we specify no layout set name, the system includes all elements of the currently open layout set. If we specify a layout set, the system uses the information about the active version of the layout set, retrieved from the database. Here we have two export parameters, Form and Language and a table parameter Elements.
READ_FORM_LINES: Use this function module to transfer the lines of a layout set element into an internal table. If we specify no layout set name, the system transfers the text lines of the currently open layout set. If we specify a layout set, the system uses the text lines of the active version of the layout set from the database. The Export parameters are Form, Language, Window and Element. If we pass these 4 parameters the function module returns a table with the lines from layout set.
Function modules are one element. There are no types. However sometimes an RFC enabled function module is referred to as RFC Function module, but really it is just a function module. Also BAPIs are function modules, but are usually referred to as just BAPI as opposed to BAPI Function module.
There is no different function module types , but calling the function module will be different.
check this function calls syntax
1. Calls a function module:
CALL FUNCTION func.
2. Call a function module in a different mode (asynchronous Remote Function Call):
CALL FUNCTION func STARTING NEW TASK taskname.

How to create RFC function module and how to call this function module

Hi,
i want to know step for creating RFC function module and then How to use this function module from some other sap system.
Thnaks,
jigar

Jigar,
To implement a remote function module in ABAP, perform the following steps:
Register the module as remotely callable in the RFC server system.
In the function module Administration screen (transaction code SE37), set the field Can be called via REMOTE CALL. Registering a module as remote causes an RFC stub to be generated for it.
Write the code for the function module.
Create the destinations.....................
Displaying, Maintaining and Testing Destinations
To display, create or modify destinations, choose Tools ® Administration ® Administration ® Network ® RFC destinations or enter transaction code SM59.
Remote Destinations are stored in table RFCDES. The RFCDES table describes logical destinations for remote function calls.
It is not possible to maintain the RFCDES table directly.
You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® AcceleratedSAP ® Customizing ® Execute Project ® SAP Reference IMG.
In the Implementation Guide, expand the following hierarchy structure:
Basis
Application Link Enabling (ALE)
Sending and Receiving Systems
Systems in Network
Define Target Systems for RFC Calls
Displaying Destinations
The initial screen for this transaction displays a tree:
Different connection types (i.e. partner systems or programs) are possible. For further information, see Types of Destinations.
To display all information for a given destination, double-click it, or place the cursor on it and press F2 .
To search for a destination, press the Find button and specify your selection. You get a list of all entries matching your selection. Place the cursor on the one you want, and press F2 or simply double-click the destination. All information for the given entry appears.
Creating Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
All available connection types are explained in Types of Destinations.
To create a new RFC destination, press the Create button. A new screen is displayed with empty fields for you to fill in.
If you want to create a new destination
As you create a remote destination, you can specify a particular application server or a group of servers for a balanced distribution of system load.
For details of the destination parameters, see Entering Destination Parameters.
Changing Existing Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
You can display all information for a given destination by double-clicking it or pressing F2 on it.
To change an existing destination, double-click it, or place the cursor on it and press the Change button.
For details of the destination parameters, see Entering Destination Parameters.
Testing Destinations
To test a destination, choose the appropriate function from the Test menu.
Connection (also available via the Test connection pushbutton)
Authorization (checks logon data)
Local network (provides a list of application servers)
You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:
CALL FUNCTION RemoteFunction
DESTINATION Dest
EXPORTING
f1 =...
f2 =...
IMPORTING
f3 =...
TABLES
t1 =...

The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. Logical destinations are defined in the RFCDES table (or the TRFCD table in R/2 Systems) via transaction sm59 or the following menu path: Tools ® Administration, Administration ® Network ® RFC destinations. You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® Customizing ® Enterprise IMG. In the Implementation Guide, you can then choose Cross-application components ® ALE ® Communication ® Define RFC destination.
The remote function call concept, for example, allows you to access a function module in an R/2 System from an ABAP program in an R/3 System. If you want to read a customer record from your R/2 Systems database, create a remotely callable function module in the R/2 environment which retrieves customer records. Call this function from your R/3 System using a remote function call and listing the destination for the target R/2 System:

Hi Aruna,
Could not get you complete question.
But you can try to create a function module which will return you time stamp, userid and other details when you call the function module.
Goto se80, create a function group to it add the function module. In the parameters of the functin module mention the importing parameters you have any (as per your requirement) and in the exporting parameter mention time stamp, userid fields and so on . in the source sode of the function module move the item stamp and other details to the interface of the function module by passing them from the system variables.
Thanks,
George
