Function Module in Generic DataSources in BI

Hi,
I appreciate your answer about the Function Module in Generic DataSources in BI.
These are the steps I followd on R/3 side.
1) Create a structure with the R/3 table fileds based on the requirement.
2) Create a function module by copying RSAX (Function Group) and RSAX_BIW_GET_DATA_SIMPLE (Functin Module) into our own function group & Function Module (name starting with Y /Z). And use the structure(ex: ZSPMT) created in the reference data of 'Tables' tab (ex: E_T_DATA LIKE ZSPMT).
3) Use the structure name & function module name in the Generic DataSource
Finally when I want to use the Generic DataSource, do i need to insert the records myself in the table (or structre) I created ZSPMT? (which is used in Function Module)
If I need to insert the data into table ZSPMT myself, what is use of function module?
Can't I use the view of this table (ZSPMT) directly in Generic DataSource?
Is the function module used to filter/restrict the data based on client need?
Thank you in advance for you answers
It will help undderstand the difference among View, InfoSet Query & Function Module
used in creating Generic DataSource.
Regards,
Lakshmi

hi,
why did you prefered function module?
if the table ZSPMT egts the data that you enter automatically then no need to use FM.
directly extract with tables/if more than one table then use views.
if you need especially the FM that could solve ur complex requirmnet.

When we go for Views and Function Modules for Generic Extraction

Hi Experts,
Can you please explain when we go for extracting the data using Views and when we got using Function Modules using Generic Extraction from R/3 system to BW with examples. And also can you explain when we go for delta for the above both scenarios.
Thanks for you help in advance
Rohith

Hi,
Scenario for Extarction using FM
Imagine the scenario where you need to extract data from
tables having no common field between them and thereby preventing you from creating a view on top of those tables..
Or simply consider tables that are highly unrelatd in terms of fields, but you have a requiremnt to extract data from them.

Business scenarios on SD and MM modules for generic datasources and enhance

Hi,
Can anybody send some documents on SD and MM module on generic datasource and on enhancements.Pl send it to my MailID:[email protected]
Thanks,
Chinna

Hi,
MM Process flow:
The typical procurement cycle for a service or material consists of the following phases:
1. Determination of Requirements
Materials requirements are identified either in the user departments or via materials planning and control. (This can cover both MRP proper and the demand-based approach to inventory control. The regular checking of stock levels of materials defined by master records, use of the order-point method, and forecasting on the basis of past usage are important aspects of the latter.) You can enter purchase requisitions yourself, or they can be generated automatically by the materials planning and control system.
2. Source Determination
The Purchasing component helps you identify potential sources of supply based on past orders and existing longer-term purchase agreements. This speeds the process of creating requests for quotation (RFQs), which can be sent to vendors electronically via SAP EDI, if desired.
3. Vendor Selection and Comparison of Quotations
The system is capable of simulating pricing scenarios, allowing you to compare a number of different quotations. Rejection letters can be sent automatically.
4. Purchase Order Processing
The Purchasing system adopts information from the requisition and the quotation to help you create a purchase order. As with purchase requisitions, you can generate Pos yourself or have the system generate them automatically. Vendor scheduling agreements and contracts (in the SAP System, types of longer-term purchase agreement) are also supported.
5. Purchase Order Follow-Up
The system checks the reminder periods you have specified and - if necessary - automatically prints reminders or expediters at the predefined intervals. It also provides you with an up-to-date status of all purchase requisitions, quotations, and purchase orders.
6. Goods Receiving and Inventory Management
Goods Receiving personnel can confirm the receipt of goods simply by entering the Po number. By specifying permissible tolerances, buyers can limit over- and underdeliveries of ordered goods.
7. Invoice Verification
The system supports the checking and matching of invoices. The accounts payable clerk is notified of quantity and price variances because the system has access to PO and goods receipt data. This speeds the process of auditing and clearing invoices for payment.
Common Tables used by SAP MM:
Below are few important Common Tables used in Materials Management Modules:
EINA Purchasing Info Record- General Data
EINE Purchasing Info Record- Purchasing Organization Data
MAKT Material Descriptions
MARA General Material Data
MARC Plant Data for Material
MARD Storage Location Data for Material

SD Process Flow:
The sales documents you create are individual documents but they can also form part of a chain of inter-related documents. For example, you may record a customers telephone inquiry in the system. The customer next requests a quotation, which you then create by referring to the inquiry. The customer later places an order on the basis of the quotation and you create a sales order with reference to the quotation. You ship the goods and bill the customer. After delivery of the goods, the customer claims credit for some damaged goods and you create a free-of-charge delivery with reference to the sales order. The entire chain of documents the inquiry, the quotation, the sales order, the delivery, the invoice, and the subsequent delivery free of charge creates a document flow or history. The flow of data from one document into another reduces manual activity and makes problem resolution easier. Inquiry and quotation management in the Sales Information System help you to plan and control your sales.
Transaction Codes:
Inquiry - VA11/VA12/VA13
Quotation - VA21/VA22/VA23
Sales Order - VA01/VA02/VA03
Delivery - VL01N/VL02N/VL03N
Billing/Invoicing - VF01/VF02/VF03

Production Planning:
For example, consider a pump manufacturing plant, based on the customer requirement, planning is done for future months ( we plan for a qty on particular
date). Pump is an assembly - were main component would be manufactured in the plant and others would be procured. As PP, we are concerned only in the inhouse
manufacturing but the final assembly (considering BOM) can be done only if the procured components are available. MRP helps in planning the shortage, on
particular date based on the planned date. Work center (ex. lathe) place the components are machined/assembled (were the operation is done). Sequence of
operation is routing (lead time scheduling data is got from routing). In the MRP Run,basic or lead time scheduling (need to know when to start/finish date)
is done. On creation of the production order, system checks for which BOM and routing to be picked up (if there are many routings or BOM for that particular
finished product). Availabilty checks for material,PRT and capacity needs to be done. on release of the order, confirmation of the order can be done (on
completion of the order or after manufacturing the quantities). GI and GR have to be done.PP flow ends here
step 1: creation of master data (Material master,BOM,Work center,Routing)
step 2: Planning - can be done by Planned independent requirement (MD61), Independent requirement (MD81).
we plan for a quantity, on which date (it would be finish date).
step 3: MD04 -stock/requirement lsit (plan made can be viewed in MD04)
step 4: MRP run - MD02, PIR is converted into Planned order
step 5:Planned order to be converted production order - CO40, CO41
step 6: production order to be released - CA02

Function Module for Generic Extractor

Hi, I have a generic extractor that uses a Function Module to extract the data. I have a change I need to make that only affects the code in the Function Module. Do I need to regenerate the DataSource or can I just change the function Module and transport the change to the function module?
Thanks for any details...

As long as you are not changing the extract structure, you do not need to regenerate the datasource or replicate. Send FM only.

Chad

How to control iteration of function module in generic extraction to BW

Hi Experts,
I am customizing standard Function module RSAX_BIW_GET_DATA_SIMPLE. My problem is, while excecuting datasource in RSA3, my function module is repeating many times.....example if my FM fetches data of 70 records.......FM is repeating 70* n times while executing it in a data source.
How to contol this loop?
Can anyone please help me.

Hi,
This FM is used to get list of files from Application server (will work in Background). This cannot be used to list files from presentation server. There is no way , by which you can process presentation server files in background mode.

How to identify update mode in function module for generic extractor

Hi All,
I have created generic extractor using function module which supports delta load.
Delta logic is handeled in coding...by using ROOSGENDLM table.
Now problem is we need to identify the update mode, requested from infopackage in our function module in order to apply logic for Repair full.
I would like to know table or parameter in source system, which contain the update mode (Init , Delta , Full).
Thanks,
Niraj

Hi Niraj
You can use the FM import parameter "i_updmode" (This is of type "SBIWA_S_INTERFACE-UPDMODE") to determine if infopackage triggerred in full or delta mode.
I_REQUNR     TYPE     SBIWA_S_INTERFACE-REQUNR
I_ISOURCE     TYPE     SBIWA_S_INTERFACE-ISOURCE                               InfoSource Name
I_MAXSIZE     TYPE     SBIWA_S_INTERFACE-MAXSIZE                               Data Packet size
I_INITFLAG     TYPE     SBIWA_S_INTERFACE-INITFLAG                               Initial Flag
I_UPDMODE     TYPE     SBIWA_S_INTERFACE-UPDMODE                               Update Mode

Function module based generic extractor - Problem with the selection

Hi all
The following is my code in the function module. I am able to get the entire data if i dont give any selections and the number of records is also correct. But when i select a MATNR value, it returns 0 records where as it needs to return 3 records. If i give selection based on bukrs, werks, lgort its working fine. But if i give selection based on MATNR, then it is not working.... I think there is a problem in the bold part of my code. If i debug, LS_MATNR is having the correct value which indicates that there is no problem with the value being passed to LS_MATNR from my selection screen of my datasource in RSA3. Even GT_WERKS is also having data. Please help.

Function module to reactivate datasource

hello all,
anyone out there with a useful function module which will allow me to reactivate a datasource?
thanks.

Hi,
You can also use the program "RSDS_DATASOURCE_ACTIVATE_ALL" to activate all / individual datasources for a source system.
Here, you also have an option to choose whether you want to activate an inactive datasource or to reactivate an active datasource. Hope this helps.

I am creating function module for generic datasource. For that I followed below mentioned steps
Steps
1.     Created s structure with the fields that needed.
2. Created FM by copying the standard Function module
" RSAX_BIW_GET_DATA_SIMPLE " and Give a New name starting With
Y or Z .
3. IN SE37 ->Your Function module name -> Change, In table tab given structure
name by deleting the associated type given in E_T_DATA .
And inserted the required code given below
      PROGRAM 'ZHU_BALANCE'.
*& Report ZHU_BALANCE
TABLES: VEKP, VEPO.
DATA: BEGIN OF T_DISPLAY,
      DATE   LIKE SY-DATUM,
      EXIDV LIKE VEKP-EXIDV,
      LGORT LIKE VEPO-LGORT,
      WERKS LIKE VEKP-WERKS,
      END OF T_DISPLAY.
DATA: ITAB_DISPLAY LIKE TABLE OF T_DISPLAY.
DATA: WA_ITAB_DISPLAY LIKE LINE OF ITAB_DISPLAY.
SELECT VEKPEXIDV VEPOLGORT VEPO~WERKS
       INTO CORRESPONDING FIELDS OF TABLE ITAB_DISPLAY
       FROM VEKP AS VEKP INNER JOIN VEPO AS VEPO
         ON VEKPVENUM = VEPOVENUM
         AND VEKPWERKS = VEPOWERKS
       WHERE VEKP~VSTEL = SPACE
         AND VEKP~VEGR1 = '401'
         AND VEKP~VPOBJ = '12'
         AND VEKP~STATUS = '0020'
         AND VEPO~VEPOS = '000001'.
LOOP AT ITAB_DISPLAY INTO WA_ITAB_DISPLAY.
WA_ITAB_DISPLAY-DATE = SY-DATUM.
MODIFY ITAB_DISPLAY FROM WA_ITAB_DISPLAY TRANSPORTING DATE.
ENDLOOP.
WRITE:/ 'DATE', 20 'EXIDV', 40 'LGORT', 60 'WERKS'.
ULINE.
LOOP AT ITAB_DISPLAY INTO WA_ITAB_DISPLAY.
WRITE:/ WA_ITAB_DISPLAY-DATE, 20 WA_ITAB_DISPLAY-EXIDV , 40 WA_ITAB_DISPLAY-LGORT, 60 WA_ITAB_DISPLAY-WERKS.
ENDLOOP.
While checking the function module its populating the syntax error as
THE TYPE SRSC_S_IF_SIMPLE IS UNKOWN. (Though this is commented in program)
So pls suggest

praful

hi indira,
thanx for ur reply we have created the funcion module successfuly it is also showing the output correct. But when we put that function module in the generic data source and try to extract data in RSA3 it shows the correct output of function module but with the msg ' 0 entries found in customer enhancement' and therfore zero records in the display list.
is there any correction or steps to be followed in data extraction
pls suggest
