ABAP Programing help regarding function modules coding

Hi,
i'm currently creating a function module that retrieve a number from a table and add one to it and return back the value to the table.
the codes are as follow:
FUNCTION ZFM_NUMBER
" * " Local Interface:
" EXPORTING
"      VALUE (ZZNUMBER) TYPE ZNUMBER
"      VALUE (ZENUMBER) TYPE ZNUMBER
SELECT ZNUMBER FROM ZTAB_NUM into ZZNUMBER.
END SELECT.
ZENUMBER = ZZNUMBER + 1.
UPDATE ZTAB_NUM SET ZNUMBER = ZENUMBER WHERE ZNUMBER = ZZNUMBER.
END FUNCTION.
this function module works finely, but now i need to concatenate the number with the year to store it into another table.
i know something about the sysdatum where i select only the first 4 characters...but i'm not sure how could i do that?
do i need to create another function module to call the above function module and concatenate it with the year?
or i just need to continue the codes in the same function module?
and how should i code it?
i'm very new to abap coding and i could'nt get help from anyone in my team. your help is very much appreciated!!!
Thanks,
leesyy

hi you can do it in the same function module.
SELECT ZNUMBER FROM ZTAB_NUM into ZZNUMBER.
END SELECT.
instead of the above statement use the following statement, it improves performance of your program
SELECT single ZNUMBER FROM ZTAB_NUM into ZZNUMBER.
in the above statement you can also specify some where condition
ZENUMBER = ZZNUMBER + 1.
UPDATE ZTAB_NUM SET ZNUMBER = ZENUMBER WHERE ZNUMBER = ZZNUMBER.
data: var_date type sy-datum,
      var_yyyy(4) type c,
      var_numyear(10) type c.
var_date = sy-datum.
var_yyyy = var_date+0(4).
concatenate ZENUMBER var_yyyy into var_numyear.
UPDATE ZTAB_NUMyear SET ZNUMyear = var_numyear WHERE ZNUMBER = ZZNUMBER.

Hello ,
There should be a number of BRF+ tutorials available in SCN which discuss the FDT APIs. You can have a look at them to get an idea of the various APIs available and their uses.
For your usecase, you should do the following.
        lo_fdt_function         TYPE REF TO if_fdt_function,
        lo_fdt_result           TYPE REF TO if_fdt_result,
* Get function handle
      CALL METHOD lo_fdt_factory->get_function
        EXPORTING
          iv_id       = lv_function_id
        RECEIVING
          ro_function = lo_fdt_function.
where lv_function_id is the GUID of the BRF+ function . You can either make it a constant , or you can use a FDT API to get the function GUID from the BRF+ application name and function name.
*   Set function context
    TRY.
        CALL METHOD lo_fdt_context->set_value
          EXPORTING
            iv_id    =
            ia_value =
This is one way to set the input context ( pass the input to the BRF+ function to process ). There are other ways to do this as well. Which one you use would depend on the kind of input you want to pass.
* Execute BRFPLUS function
TRY.
      CALL METHOD lo_fdt_function->process
        EXPORTING
          io_context = lo_fdt_context
        IMPORTING
          eo_result = lo_fdt_result.
* Get result output
TRY.
      CALL METHOD lo_fdt_result->get_value
        IMPORTING
          ea_value =
Another direct way of doing it would be to use the method PROCESS of the class CL_FDT_FUNCTION_PROCESS.
I have not gone into much explaination here , but it should provide you an idea of how you can go about it.Read the SCN docs on the APIs to get a better idea , or better still if you can get hold of a copy of the BRF+ book by Carsten Ziegler , you will get an end to end explaination of all BRF+ APIs in it.

Need help regarding Java decoding of IMAP attachment (IOStream related ques

Hi ,
I need some help regarding the processing of an IMAP attachment , It is a basic IOStream related question I guess.
I have some attachment to a mail , I try to fetch it using javamail and read the content and write it to a file , I was able to do it successfully when I was using stream.read( tempBuffer) function but when I started using stream.read( tempBuffer, 0, m_maxDataSize ); it is giving me following exception
java.io.IOException: Error in encoded stream: needed at least 2 valid base64 characters, but only got 1 before padding character (=), the 10 most recent characters were: "/59PT/eXQ="

Need help regarding the dunning form

Hi,
I have to display all the sales and payments of a cusomter for all the periods that are older than the run date in a dunning form. (i.e) if the run date is 04-aug-05 and if the slaes are there in 3 months(april, May, july) then i have to display three line items with sales and payments for that corresponding three months in the line items. As this is a dunning form i cannot change the print program. any table which have all the sales for a period which i can access directly in the script. can anyone suggest how to handle this.
regards,
Asha

Hi,
You can call a subroutine within a program (your z program)
/:   PERFORM ADD_AMOUNT IN PROGRAM SAPLZFTP_F150
/:           USING &W_AMOUNT&
/:   ENDPERFORM
In the z program create this subroutine.
      Form ADD_AMOUNT
     -->FT_INVAR Text Symbol table for input variables
     -->FT_OUTVAR Text Symbol table for output variables
FORM add_amount TABLES ft_invar   STRUCTURE itcsy
                       ft_outvar STRUCTURE itcsy.
STATICS:
    w_value_l    TYPE f150d-salfw.
        READ TABLE ft_invar INDEX 1.
        IF sy-subrc IS INITIAL.
you can check all this part of the code how you want to
process your data whether its numeric or character or
whatever
           w_value_l = w_value_l + ft_invar-value.
        ENDIF. "IF sy-subrc IS INITIAL.
ENDFORM.                    " ADD_AMOUNT
TO BESPOKE THE PRINT PROGRAM FOR THE DUNNING
Dunning outputs use the function module FI_DUNNING_PRINT_NOTICE. You can copy this to a Z function module and make some changes to the data selection. You will have to look into the code and decide what changes you need.
The process to use a bespoke program to do the dunning print is as follows:
UNDER FI GLOBAL SETTINGS in the configuration,
There are Business Transaction Events. Within that you can configure the same to enable a Z function module in place of the standard function module (from the FUNCTION GROUP F150)
Create function group ZFTP_F150
Copy standard function module FI_PRINT_DUNNING_NOTICE of function group F150 to ZFTP_FI_PRINT_DUNNING_NOTICE in function group ZFTP_F150
Copy standard function module PRINT_DUNNING_NOTICE of function group F150 to ZFTP_PRINT_DUNNING_NOTICE in function group ZFTP_F150
Within the function module ZFTP_FI_PRINT_DUNNING_NOTICE, change function module call for PRINT_DUNNING_NOTICE to ZFTP_PRINT_DUNNING_NOTICE
Create a new include ZFTPI_ROUTINES within the function group and copy the subroutines LOG_MSG, LOG_MSG_TAB, & LOG_SYMSG from the function group F150 to this include
AS AN ALTERNATE, YOU CAN COPY THE WHOLE FUNCTION GROUP
Maintenance view TBE31 (SM30). Change the function module from FI_PRINT_DUNNING_NOTICE to ZFTP_FI_PRINT_DUNNING_NOTICE against the event 00001720 FI-FI entry
Hope this helps.

Regarding Function Module trace.

Hi,
How are you ?. I need a help for Function Module datasources of how to get info of fields related to tables. I tried ST05 of SQL Trace but not showing complete picture and I heard through ST12 can do Function module trace to obtain table names. Can you kindly walk me through of how to Obtain table names for fields for Function Module Datasources through ST12 or any tcode in detail.
Thanks in advance.
Regards
Srinivas M.

Hi Srinivas,
I suggest to first have a look at the SAP Help for Business Content DataSource. You might find information on the source tables here.
As a next step you can have a look in the coding of the Function Module or debug it. You have to look to statements like TABLES and SELECT.
As a last step (and maybe time-consuming) execute an SQL Trace using t/code ST05 during executing t/code RSA3 in the Source System.
Best regards,
Sander

Help regarding data element

I need some help regarding data element ZEXPDT. I used it in an infoquery that was transported to QAS and it does not exist in QAS. I thought it might be locked in a transport, but the below screen clip says it is not locked. It was created in 3/2014. Thanks.

Either trick the system, SE11, add a space at end of text desciption and save,
Or call transport workbench (SE01, SE10) create a transport request or use an existing one, then double-click on a task, switch to modify mode, add a line with R3TR DTEL name of the data element, save, then object list, lock in request/task menu.
Or SE80, contextual menu of data element. (other functions, write transport entry)

Help regarding :Video Segmentation & Summerization

hello friends,
I am doing my project on above topic and I am trying it with Java.
Is it possible doing it in Java.
What Techniques I'm using are:
1.Java(JMF)
2.Oracle 9i(Inter-Media)
3.Matlab
This project concludes of four parts
1.Segmentation (Video to Image conversion)
2.Comparison (Copare frame using algo.)
3.Extraction (remove duplicate frames based on algo)
4 Summarization (Collect frames and form a new content based video)
Is It possible in Java? How?
Seeking for help regarding this .
Thank you.

This project concludes of four parts
1.Segmentation (Video to Image conversion)
2.Comparison (Copare frame using algo.)
3.Extraction (remove duplicate frames based on algo)
4 Summarization (Collect frames and form a new content based video)So, compressing that into a simple question instead of a convoluted one... you just want to remove duplicate frames from a video and save it to file?

Dilemma regarding function based indexes

Hello,
I have a dilemma regarding function based indexes.
I have read Note:66277.1 on the Metalink discussing thoroughly the subject of “Concepts and Usage of Function Based Indexes”.
This doc was revised on 30-May-2006 so I was sure it referred to 9i and 10g.
This doc as well as other docs on the web claim that in order to use FBI (function based indexes) one must set the following parameters (can be done also at session level)
QUERY_REWRITE_ENABLED = TRUE
QUERY_REWRITE_INTEGRITY = TRUSTED
Also the schema that is owner of the FBI should be granted with QUERY REWRITE sys priv and statistics should be collected since FBI is usable only by CBO (cost based optimizer).
I have tested it and it works, my problem was that it worked
(1)     Without granting the QUERY REWRITE to the owning schema.
(2)     QUERY_REWRITE_ENABLED was set to false.
(3)     QUERY_REWRITE_INTEGRITY was set to enforced.
I have conducted my tests on 9.2.0.6 and found no evidence in the docs (10g) saying the above is required or not.
I found at http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:1197786003246 the following:
“Oracle9iR2 relaxed this so that the FBI on the builtin function may be used.”
so I have tested it with my own function:
create or replace function upper2( p_str in varchar2 ) return
varchar2 DETERMINISTIC
as
begin
return upper(p_str);
end;
=>
Also (yes you guessed right), without any privilege granted nor parameter setting the optimizer picked my FBI.
Can anyone refer me to a place documenting this behavior as a correct one?
Other comments?
Regards,
Tal Olier ([email protected])

Got an answer from Oracle support:
19-DEC-06 18:04:31 GMT
(Update for record id(s): 101017780,101017796)
QUESTION
========
Questions about the options required in 10g related to Function Based Indexes, and the correct
behaviors associated with them.
ANSWER
======
For 10g:
These requirements are no longer true in 10g. This has already clarified by
development in the Bug 3999326 which is available on metalink.
For 9I:
For the creation of a function-based index in your own schema, you must be
granted the QUERY REWRITE system privileges. To create the index in another
schema or on another schema's tables, you must have the CREATE ANY INDEX
and GLOBAL QUERY REWRITE privileges.
You must have the following initialization parameters defined to create a
function-based index:
QUERY_REWRITE_INTEGRITY set to TRUSTED
QUERY_REWRITE_ENABLED set to TRUE
COMPATIBLE set to 8.1.0.0.0 or a greater value
Additionally, to use a function-based index:
The table must be analyzed after the index is created.
The query must be guaranteed not to need any NULL values from the indexed
expression, since NULL values are not stored in indexes.
However, in 9.2.0.4 patchset, these prerequisites do not apply and one can
create function-based indexes without any of the above to be true. This is not
the case in 9.2.0.3, not in 8.1.7.
