Generic data extractor using a function module

Hi All,
I want to create a generic data extractor using a function module within the BW system. i.e. the extractor will run in BW and and store the data in a cube( in BW). No R/3 is invloved. I proceeded as follows:
1. Created a structure through se11.
2. Created a function module. But while defining "E_T_DATA" in the "Tables" section of the function module, I am getting the error "TABLES parameters are obsolete". I defined as follows:
E_T_DATA TYPE ZBW_EXTRACT
ZBW_EXTRACT is the name of the structure.
What should i do in this case ?
Thanks,
Satya

Hello Satya,
The message "TABLES parameters are obsolete" is just a warning and not an error. The structure of the interface is strict (defined by SAP). You should opt to proceed even if you receive the warning.
Hope this clarifies.

Hi,
I went to se80. Copied the function module "RSAX_BIW_GET_DATA_SIMPLE" to my function group. When i tried to change the associated type from "SFLIGHT" to my own structure, it again gives a warning that "TABLES parameters are obsolete!". It does not allow me to either save, check or activate the function module. What should i do ?
Please reply urgently.

Generic Data Source Based On Function Module (Delta capable)

Hi,
My requirement is to develop a Generic Extractor based on Function Module (Delta capable). As I already found many threads explaining this concept, but most of them discussing FM RSAX_BIW_GET_DATA_SIMPLE with Extraction Method F2. There is another FM RSAX_BIW_GET_DATA which, one can use to build delta enabled extractor.
Although I do have some doubts:
what is the E_T_SOURCE_STRUCTURE_NAME ?
read table i_t_select into l_s_select with key fieldnm = 'PGMID'. Use of this code ?
Templet only showing
case i_updmode.
      when 'F'.
      when others.
        if 1 = 2. message e011(r3). endif.
        log_write 'E'                  "message type
                  'R3'                 "message class
                  '011'                "message number
                  i_updmode            "message variable 1
                  ' '.                 "message variable 2
        raise error_passed_to_mess_handler.
    endcase.
i.upmode as F, D(delta) is not included, do i need to include this?
Can someone help to solve this. Appropriate points will be allotted to helpful suggestions.

Try using following piece of code;
READ TABLE g_t_select INTO l_s_select
                             WITH KEY fieldnm = 'Date Field for Delta'.
      IF sy-subrc EQ 0.
SELECT SINGLE *
                       FROM ROOSGENDLM
                       WHERE oltpsource EQ 'DataSource Nameu2019
                       AND slogsys      EQ lw_slogsys.
          IF sy-subrc EQ 0.
            lw_date = roosgendlm-deltaid+0(8).
            lw_time = roosgendlm-deltaid+8(6).
                                                                                ENDIF.                       " IF SY-SUBRC EQ 0.
ENDIF.
OPEN CURSOR WITH HOLD S_CURSOR FOR
SELECT * FROM TABLE
                               WHERE CPUDT     GE   lw_date   AND
                                           CPUTIME GE   lw_time.
    ENDIF.
Table R00SGEMDLM stores the date and time data was last extracted from a data source.
Alternatively, you can also try using the i_updmode.
When 'F'.
SELECT * FROM TABLE (without any where clause on last change date)
When 'D'
SELECT * FROM TABLE
                               WHERE CPUDT     GE   lw_date   AND
                                           CPUTIME GE   lw_time.
These are just suggestions. Try these out, I hope it helps.

Global data declaring/using in Function modules

Hi,
I have declared an internal table(say ITAB1) in the top include.Appending the values through FM1(function module).
I am using the same through FM2 (Tables ITAB1).
( Function group is same for both FM1 and FM2 )
but i am not getting the values in the ITAB1.
Can anyone help me....
Thanks in advance
KB

Bhavani,
I don't think it works that way. If you are accessing that variable with in that function module you will be able to access that table.
As you are calling another function module else where, the execution memory is different and the previous variables will not exist any more. However, if you call function2 with function1 it should work.
The other way could using the EXPORT and IMPORT commands. Then you should be able to access the data.

Ravi

Error while creating Generic data source using FM

Hi Experts,
I try to create a generic data source using the Function Module via the transaction RSO2. I got the following error messages.
" Das Einheitenfeld CURR des Feldes ZPKZA1 der DataSource ZBWN_DS_POLPOSP ist ausgeblendet"
" Das Einheitenfeld CURR des Feldes ZPKZA2 der DataSource ZBWN_DS_POLPOSP ist ausgeblendet"
" Das Einheitenfeld CURR des Feldes ZPKZA10 der DataSource ZBWN_DS_POLPOSP ist ausgeblendet"
"The unit field CURR of the field ZPKZA1 of the DATA SOURCE ZBWN_DS_POLPOSP is not visible/ stopped/ hide".
for all 10 fields of type CURR.
How shall i handle this issue..........any suggestions please........
thanks in advance
cheers
sailekha

Hi,
Are your CURR fields refereded to a currency field of your structure?? Maybe the problem is that the field containing the currency is refered to other table/structure and it has to be one of your structure fields.
Hope this helps,

Use of Function Module IDOC_INPUT_CREDITOR

Hi All,
Could you please let me know the use of the function module IDOC_INPUT_CREDITOR. If i customise this function module by copying to Z_IDOC_INPUT_CREDITOR.. is it possible for me to post the vendor classification data by using the function module.
Thank You,
Suresh

Hi,
This function module is used to post Vendor realted information through IDOCs. You can copy the same and can create your own but you need to attach this to your own IDOC message type or you can call through your own customized transaction.

Updation of material data using a function module

HI
i want to update fields in the mvke table,but the field is a Customer field in the table, not sap table field.i want to update the field using a program , not going to mm02. which function can i use for the updation.There is a function module MATERIAL_MAINTAIN_DARK for updation,will this funtion module update the customer fields also. Can anyone tell me about this function module and how to use this function module or MATERIAL_MAINTAIN_DARK.

Using the function Module BAPI_MATERIAL_SAVEDATA , you can also update the custom fields.
This is the documentation for the extension fields:
<b>Reference Structure for BAPI Parameters EXTENSIONIN/EXTENSIO
Description
    You use this structure to transfer the material's customer-defined
    fields. For information on transferring these fields, see the function
    module documentation.
Note
    Besides the table fields already defined, customer-defined table fields
    can also be supplied with data. Since these fields are created by the
    customer, they are known only during the runtime and must therefore be
    determined dynamically.
    The structures BAPI_TE_<NAME> (<NAME> = MARA, MARC, MARD, MBEW, MLGN,
    MLGT, MVKE) and the relevant checkbox structures BAPI_TE_<NAME> (<NAME>
    = MARAX, etc.) must first be extended by the customer to include the
    fields required. The standard structures contain only the corresponding
    key fields. When including new fields in these structures, make sure
    that the field has the same name as the field in the database table. In
    addition, the fields in the structures BAPI_TE_<NAME> may only be of the
    type CHARACTER. The data element BAPIUPDATE must be used for the fields
    in the checkbox structure (except for key fields).
    The two parameters EXTENSIONIN and EXTENSIONINX are used to transfer the
    data to the method. The field STRUCTURE contains the name of the
    structure (for example, BAPI_TE_MARA or BAPI_TE_MARAX) used to identify
    the work area (for example, WA_BAPI_TE_MARA or WA_BAPI_TE_MARAX) to
    which the data is transferred. The remaining fields for the parameter
    EXTENSIONIN or EXTENSIONINX contain the data for the key fields (for
    example, the material number) and the data for the customer-defined
    fields. The number of characters reserved in the two parameters for the
    content of a customer-defined field must be the same as the number of
    characters for the corresponding work area field. If the number of
characters required is smaller, the remaining characters in the two
parameters must be filled with blanks. Only then may the content of
another field be transferred. Here too, remember that the data is
written to the database only if the corresponding indicator has been set
in the work area.</b>

Generic Extraction business Requirement, through function module,

Generic Extraction business Requirement, specifically through function module and source code in function module.

Dear Karthik,
Go to transaction SBIW -> Generic Datasource -> Maintain Generic Datasources -> Choose Master/Transaction Data -> Maintain proper entries (Application Component, Descriptions) -> Extraction by FM if you want to extract using FM.
Maintaining Generic DataSources - Independently of application, you can create and maintain generic DataSources for transaction data, master data attributes or texts from any kinds of transparent tables, database views, InfoSets of the SAP query or using a function module. As a result, you can make use of the generic extraction of data.
Creating a Generic DataSource
       1.      Select the DataSource type and give it a technical name.
       2.      Choose Create. The creating a generic DataSource screen appears.
       3.      Choose an application component to which the DataSource is to be assigned.
       4.      Enter the descriptive texts. You can choose any text.
       5.      Choose from which datasets the generic DataSource is to be filled.
                            a.      Choose Extraction from View, if you want to extract data from a transparent table or a database view. Enter the name of the table or the database view.
After generation, you get a DataSource whose extract structure is congruent with the database view or the transparent table view.
For more information about creating and maintaining database views and tables, see the ABAP Dictionary Documentation.
                            b.      Choose Extraction from Query, if you want to use a SAP query InfoSet as the data source. Select the required InfoSet from the InfoSet catalog.
After generation, you now have a DataSource whose extract structure matches the InfoSet.
For more information about maintaining the InfoSet, see the System Administration documentation.
                            c.      Choose Extraction using FM, if you want to extract data using a function module. Enter the function module and extract structure.
The data must be transferred by the function module in an interface table E_T_DATA.
For information about the function library, see the ABAP Workbench: Tools documentation.
                            d.      With texts, you also have the option of extraction from domain fixed values.
Maintain the settings for delta transfer where appropriate.
       7.      Choose Save.
Note when extracting from a transparent table or view:
If the extract structure contains a key figure field, that references to a unit of measure or currency unit field, this unit field must appear in the same extract structure as the key figure field.
A screen appears in which you can edit the fields of the extract structure.
       8.      Editing the DataSource:
       Selection
When scheduling a data request in the BW Scheduler, you can enter the selection criteria for the data transfer. For example, you may want to determine that data requests are only to apply to data from the previous month.
If you set the Selection indicator for a field within the extract structure, the data for this field is transferred in correspondence with the selection criteria in the scheduler.
       Hide field
You should set this indicator to exclude an extract structure field from the data transfer. As a result of your action, the field is no longer made available in BW when setting the transfer rules and generating the transfer structure.
       Inversion
Reverse postings are possible for customer-defined key figures. For this reason, inversion is only possible for certain transaction data DataSources. These include DataSources that have a field that is indicated as an inversion field, for example, the field update mode in the DataSource 0FI_AP_3. If this field has a value, then the data records are interpreted as reverse records in BW.
Set the Inversion indicator if you want to carry out a reverse posting for a customer-defined field (key figure). The value of the key figure is then transferred in inverted form (multiplied by 1) into BW.
       Field only known in exit
You can enhance data by extending the extract structure for a DataSource using fields in append structures.
The indicator Field only known in Exit is set for fields of an append structure. In other words, by default these fields are not passed onto the extractor from the field list and selection table.
Deselect the indicator Field Only Known in Exit to enable the Service API to pass on the append structure field to the extractor together with the fields of the delivered extract structures in the field list as well as in the selection table.
9. Choose DataSource -> Generate.
The DataSource is now saved in the source system.
Maintaining Generic DataSources
·        Change the DataSource
To change a generic DataSource, in the initial screen of DataSource maintenance, enter the name of the DataSource and choose Change.
You can change the assignment of a DataSource to an application component as well as the texts of a DataSource. Double-clicking on the name of the table, view, InfoSet or extract structure takes you to the appropriate maintenance screen. Here you can make changes required to add new fields. You can fully swap transparent tables and database views, but not InfoSets. If you return to the DataSource maintenance and choose Create, the screen for editing a DataSource appears. To save the DataSource in the SAP source system, choose DataSource -> Generate.
If you want to test extraction in the source system independently of a BW system, choose DataSource -> Test Extraction.
·        Delta DataSource
In the Change Generic DataSource screen, you can delete any DataSources that are no longer relevant. If you are extracting data from an InfoSet, delete the associated query. If you want to delete a DataSource, this must not be connected to a BW system.

How to Use ECC function Module

Hi Experts - We need to execute the function module in ECC and need to write data in Oracle table.
We are using BODS 4.0.
How to use function module in data flow ? how it can work as a source ?
I just need some basic steps how to use function module as a source and do the transformation to target.
Thanks
R

Hi Ashwani,
It is still not possible to use a FM as a source in DS.
You can use a FM in a transformation but you have to start from a file or table as a source and load into a target (a FM can not be an end point of a dataflow - as it is used in the transformation and each transformation requires a source and a target.
The scenario I described above was based on a situation where you have a source (flat file or table) and want to use a Function Module to transform your data and/or load the data in a transparant table in SAP.
Your scenario is different, as your source is not a table/ff but a FM.
In your case, I can see two scerio's:
- Use an ABAP dataflow. Although I haven't got any experience with this I do believe this would be an option for your scenario. Please referer to the Data Services documentation on ABAP dataflows for further guidance.
- As suggested earlier, you can create a bespoke (BW) Datasource based on a Function Module. Please refer to SAP help for creating a generic datasource:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/e3/e60138fede083de10000009b38f8cf/frameset.htm
Depending on your scenario there might be a third option:
- Use a SAP transparant table as a source. Create a transformation into the designated Oracle table. In the transformation call a FM which executes whatever logic you require. This solution will work if you have a table which produces the same number of records as your FM. If your function module produces more or less records (than there are in the transparant table), then this might become a bit tricky. It might work, but I have never tried it.
Instead of a transparant table you can also use a table join, obviously. Perhaps part of the complexity of your FM could be resolved by using a join and you can create a new simpler FM for the remaining logic?
Good luck,
Jan.

Null character removal in sap using a function module

Little background :
1) we are using a lot of interfaces with legacy and the data in sap has null characters for example : phone#123 .
the prob is not on sap side but on bw side when i extract this data it converts to hex format and the load fails.
2) so i wrote a abap function module for the extractor which uses the function modules SRET_TEXT_TO_BINARY and SRET_BINARY_TO_TEXT and passed the variable that has the null character and replaced it with space.
3) the prob is i get null characters in a lot of fields now and i am not sure how i can pass it to SRET_BINARY_TO_TEXT OR SRET_TEXT_TO_BINARY as they are SAP standard and it takes in just a single variable. i have all my fields in a internal table .

I am using the function module "KCD_EXCEL_OLE_TO_INT_CONVERT" to upload the excel template to an internal table but i am not getting the complete excel data into the table the fields which contains the drop down list values those values are not coming in to the table.
Is there any other function module which can read even the drop down list values? can any one please provide me the solution.
Thanks in advance
** FYI...i am using the below code:
* upload excel file to a generic table
   CALL FUNCTION 'KCD_EXCEL_OLE_TO_INT_CONVERT'
     EXPORTING
       filename                = l_filename
       i_begin_col             = 1
       i_begin_row             = 1
       i_end_col               = 150
       i_end_row               = 65000
     TABLES
       intern                  = lt_intern
     EXCEPTIONS
       inconsistent_parameters = 1
       upload_ole              = 2
       OTHERS                  = 3.
   IF sy-subrc <> 0.
     MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
             WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
   ENDIF.
