Doubt in function module relating to delta upload

Hi,
Is there any ABAPer alive around who can tell me how i can write a funtion module to update data to BW side.
They only tell me data is not going to BW side. Can anyone throw light as to how function module should be structured. I have a function module that works very finely for full update mode in RSA3. What should be done in my function module for delta update mode to work on BW side?????
<h1> THIS IS CRITICAL </h1>
Regards,
Prakash.K

Critical? Why? Should I respond faster because you've a problem that's urgent for you?
Does full extraction work when you run the extraction from BW? Extraction only stops when you return an empty package. Hence, RSA3 won't tell you if you've made this mistake. RSA3 will work fine, but the extraction will never end when run from BW. I refer you to this discussion I had earlier. [Re: Transport Organ9izer] I'll emphasise one important point: Also SAP supply RSAX_BIW_GET_DATA_SIMPLE as an example of how to write FM extractors
If your FM is actually working with full, then to get your function module to work as a delta load, you need to be able to determine which data records have changed with since the last extraction, and only send those. How you do this depends very much on the data. You'll also have to define the datasource as Generic.

How to find out the Functional module related to a T-code

Hi All ,
Please tell how to find out the Functional module related to a T-code.
i want it for the T-code RSZDELETE.

Hi
There is no direct way to see this.
You need to Pick the Program(Se37/38) and tables (SE16/11)and to see where its been used
The FM for RSZDELETE is RSZ_DB_COMP_REORG_AS_POPUP.
Hope it helps

Function Module Extractor with Delta

I'm very new to working with the BW, so I hope I'm explaining my question in a way that makes sense.
I need to make a BW extractor that pulls data from at least one table, possibly more, and which also calculates some data.
I think the only way I can do that is by using an extractor with a function module.
I've been looking at the examples in function group RSAX, and I think I sort of get it, except for one part.
I'm really confused about how the delta works.
I'm looking at the example: RSAX_BIW_GET_DATA_SIMPLE
Does it even use a delta?
I'm trying to understand how the delta gets passed, and how it gets used to filter the data in the function module. I'm not sure if it's something I need to code in myself, or if it's something that BW does by itself, or what.
I'm not sure if I'm making sense, but if anyone could help me, I'd appreciate it.

Thanks guys, you've been super helpful so far, so I'm just going to keep asking questions. I promise to award points at the end
I'm looking at it now, and I think if I change it to read from a table, instead of read from a function module I can use the 'numeric pointer' option for the delta. (Does that just mean a number? For example, payroll runid is a number, so I could use that and only get new payroll runs?)
However, there still are some calculated fields they want. Someone mentioned doing that on the BW side. How would that work?
Sorry for such vague questions, but any help is really appreciated.

Extractor on Function Module Not Passing Deltas

Hi Experts,
We have created an extractor on a function module in ERD and initialized it in BWD with no issue. However, when we change a record in ERD, the delta is not passed to BWD. We have debugged the function module and it appears the records are being written to the BW Delta Queue tables but they are not visible in RSA7 and are not picked up by BW. We think there may be a problem in the Decode by Playback method writing the records back to the structure.
The Generic Delta of the extractor is set to Additive Delta and the Delta Mode is AIM (After images by Delta Queue); however we have tried different modes to no avail. Any insight you can share is appreciated.
Thanks,
Michael

Hi
In FM check on which fields you have written delta logic, data will populate if we have changes to that field.
we have some good documents on step by step of creating FM based generic extractors. check if you miss any steps

Doubt in function module BAL_DSP_LOG_DISPLAY

Hai, guys,
i have doubt in the function module BAL_DSP_LOG_DISPLAY.
actually after executing the functin module bapi_acc_document_post, how to pass bapi return table to this function module bal_dsp_log_display.
if any one know means please tell me with sample coding.
thanks in advance.
From Elamaran.

Hi Elamaran!
Did you try to use SE37 with this module and use "Where-Used List" (CTRL + SHIFT + F3)? This should give you enough examples to look through.

Function Module Extractor with Delta Functionality

Hi Friends,
I have to extract the entire data of CDPOS table in R/3 , as its a cluster table I am unable to build a view, I am planning to go for FM extraction, Could someone help me as how to build it with Delta Functionality.
I think I need to develop the Datasource, with Extract Structure,( Do I need to create a Structure in SE11) Please help me out .
Thanks,
Krish

Hi,
you can either use an existing structure or else create one on your own. (SE11).
The DeltaHandlig fairly easy.
When having finished the extractor (FunctionModule, Structur and DatasSource), go to the "generic Delta" button and select the relevant field.
The Generic Delta and its DeltaPointer is managed within the DeltaQueue (RSA7) and works more or less like a selection. Don't think too hard about it in your function module except taht you need to select by this field in your FM.
Did that come clear?

plz help me .......

Hi
See the doc on fun modules and create accordingly
Function Modules;
Check this matter.
Function Modules are Global ABAP programs created by SAP for reusable purpose.they have IMPORT,EXPORT and TABLE parameters, and EXCEPTIONS to through when error occurs.
You can create them from TCode SE37.
Go through the following doc:
Function modules are cross-program, reusable procedures that are organized into function groups, and whose functions are implemented between the statements FUNCTION and ENDFUNCTION. Function modules and their interfaces are created in the Function Builder.
Function Module Interfaces
The parameter interface of a function module is defined in the Function Builder. It includes the definition of interface parameters and the specification of exceptions that can be triggered by a function module. The Function Builder automatically generates comment lines below the FUNCTION statement in the source code of the function module, which represent the interface of the function module with the following syntax:
Syntax
... [IMPORTING parameters]
[EXPORTING parameters]
[CHANGING parameters]
[TABLES table_parameters]
[{RAISING|EXCEPTIONS} exc1 exc2 ...]
The syntax and semantics of IMPORTING, EXPORTING, CHANGING, RAISING, and EXCEPTIONS mainly correspond to the definition of method interfaces with [CLASS-]METHODS. The additional option of defining table parameters using TABLES is obsolete.
Interface parameters
The interface parameters are defined on the relevant tab pages in the Function Builder.
IMPORTING parameters are input parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input parameter. The content of the actual parameter is passed to the input parameter when the call is made. The content of an input parameter for which 'pass by reference' is defined cannot be changed in the function module.
EXPORTING parameters are output parameters. When the function module is called, a suitable actual parameter can be specified for every output parameter. The content of an output parameter that is defined for 'pass by value' is transferred to the actual parameter if the function module is completed without errors. An output parameter that is defined for pass by reference is not initialized when the function module is called.
CHANGING parameters are input and output parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input or output parameter. When the function module is called, the content of the actual parameter is passed to the input/output parameter, and when the function module is completed, the content of the input/output parameter is passed to the actual parameter.
TABLES parameters are table parameters. Table parameters are obsolete CHANGING parameters that are typed as standard tables with a header line. If an internal table without a header line or a table body is passed as an actual parameter to a formal parameter of this type, an empty local header line is generated in the function module. If an internal table with a header line is used as an actual parameter, both the table body and the header line are passed to the function module. Pass by value is not possible in formal parameters defined using TABLES. Formal parameters defined with TABLES can be replaced by formal parameters defined with CHANGING. A local work area can be created for the internal table in the function module by using the addition LIKE LINE OF itab of the DATA statement.
Exceptions
The exception of a function module are defined on the Exceptions tab page in the Function Builder. Here you can select exception classes to define whether class-based exceptions are declared or non-class-based exception are defined. Class-based exceptions are represented in the above syntax by RAISING, and non-class-based exceptions are represented by EXCEPTIONS.
The addition RAISING is used to declare class-based exceptions that can be propagated from the function module to the caller. Exceptions in the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be explicitly declared, otherwise a propagation can lead to an interface violation. A violation of the interface leads to the treatable exception CX_SY_NO_HANDLER. Exceptions of the category CX_NO_CHECK are implicitly always declared. The declaration of exceptions of the category CX_STATIC_CHECK is statically checked in the syntax check. For exceptions of the category CX_DYNAMIC_CHECK, the check is not performed until runtime. In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure.
The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be triggered in the function module using the statements RAISE or MESSAGE RAISING. Exceptions defined in this way - as with formal parameters - are bound to the function module and cannot be propagated. If an exception of this type is triggered in a function module, and no return value has been assigned to it with the homonymous addition EXCEPTIONS of the CALL FUNCTION statement when the call was made, this leads to a runtime error.
Note
For new developments after release 6.10, SAP recommends that you work with class-based exceptions that are independent of the function module.
RFC is a technology which is used to access a functions (Modules) from
the remote systems.
If a function module is set as remote enabled which can be access from
the remote system via RFC.Eg: U can access the Remote enabled function modules in ur VB,Webdynpro,Java,Visual composer program.
A function module can be set as remote enabled by SE37->Go to ur FM->click the option Button "remote enabled".
But Normal function modules can not accessd from the remote system.
Good Example for RFC enabled function module is : BAPI(Business Application Programming Interface)
Note: All BAPIs are Remote enabled but not all remote enabled function modules are BAPI.
CALLING A FUNCTION MODULE:
1)In U ABAP Editor --> Click "Patter" ---> Selection Option Button "Call Function"
--> Write the Corresponding FM name --> Hit Enter
2)The appropriate import ,export Parameters will be displayed in ur editor
3)Pass the Values Here.

Function Modules related to BOM

Hi BW Gurus,
I am having a requirement to extract data from the function module for the PP module for the standard BOM.
I found out some function modules for my requirement csap_mat_bom_read and my problem here when i am trying to create a generic data source on using this function module it displays a error msg " The specified table does not exist ".
I am working first on function modules please let me know whether these function modules useful to fetch data in BW or not.
Give me your input of how to proceed further.
Regards,
Syed

Hi Shahid
You cannot create a generic datasource directly on a SAP standard function module, you should either create a custom FM and use the standard FM to get the data to a internal table and pass the values to a structure of datasource. Or use SAP tables to extract data to ITAB.

Check the following code for subtract years/months/date from particular date:
DATA: EDAYS LIKE VTBBEWE-ATAGE,
EMONTHS LIKE VTBBEWE-ATAGE,
EYEARS LIKE VTBBEWE-ATAGE.
PARAMETERS: FROMDATE LIKE VTBBEWE-DBERVON,
TODATE LIKE VTBBEWE-DBERBIS DEFAULT SY-DATUM.
call function 'FIMA_DAYS_AND_MONTHS_AND_YEARS'
exporting
i_date_from = FROMDATE
i_date_to = TODATE
I_FLG_SEPARATE = ' '
IMPORTING
E_DAYS = EDAYS
E_MONTHS = EMONTHS
E_YEARS = EYEARS.
WRITE:/ 'Difference in Days ', EDAYS.
WRITE:/ 'Difference in Months ', EMONTHS.
WRITE:/ 'Difference in Years ', EYEARS.
INITIALIZATION.
FROMDATE = SY-DATUM - 60.
For difference between two dates.
data : date1 like sy-datum,
date2 like sy-datum,
diff(10 ) type c.
date1 = '20071003'.
date2 = '20071104' .
CALL FUNCTION 'DAYS_BETWEEN_TWO_DATES'
