Diff b/w BAPI and Function Module.

What is the difference between BAPI and Function Module....
By Interface programming do we mean posting data thru BAPI,BDC....

Hi Alex,
BAPI: Standard Interface in the R/3 system that allows the system to communicate with components of other business suites.
FM: These are the procedures that are defined in the Function Groups and can be called from any ABAP Program. FM allow you to encapsulate and reuse global functions int he R/3 system.
The main basic difference between BAPI and FM are
1) All BAPIs are FM but not all FMs are BAPIs
2) BAPIs are remote enabled
3) BAPIs interface will not have a changing and exceptions. They can not be used to have use dialog.
Interface programs can post data to SAP either through a BDC, BAPI, IDOC etc. It depends on the type of requirement.
Hope this solves your question.
Enjoy SAP

Difference between bapi and function module

Can you guys tell me what are the differences in calling bapis and function modules?
I see we are calling both as the same way we call function modules. May be for bapis, we need to be careful in declaring and passing those exact structures. Can you please make it clear reg. the differences between them?
I appreciate it.
Thanks!

HI,
See these links on help.sap.com
<b>For BAPI:</b>
The data entered in the Internet is transferred to the R/3 System via BAPIs (Business Application Programming Interfaces).
Data in the R/3 System is accessed via BAPIs as well.

<b>For Function Module:</b>
The important use of functional module is it is used by Enhancements.
SAP Enhancements are used to expand the standard functionality within SAP.
Enhancements use function modules and are called from the standard SAP code.

hi
BAPI is a function module used in specific cases and they are better
in those particular ones cause they make many checks, so if you have two
options: a function module and a BAPI i�d tell you to use a BAPI.
If you have any other doubts about some BAPIS in particular, be sure to use
transaction BAPI
they have great documentation there.

Bapi and Function Module

Hi,
I'm working on some PM realted stuff, in which i need to use BAPI_ALM_ORDER_GET_DETAIL
where i need some fields from export parameters, giving the input as order number.
But it is exporting a structure, so i'm not sure how to get the fields from the structure(i.e,
How to retrive data from the structure ),
since i could get data only from table or internal table.
SO please guide me in getting data from this structure
Or how can i assign this structure to the Interanl table or some how to retrive data.
In short guide me how to use this function module, to retrive data like order type, location, plant and many other stuff.
Thanks and regards
Rich

if the exporting parameters are like structure, it means its header data.
Define any structure as type of BAPI structure. use the function module. you will have all the header data in that structure. Structure means a single string of data with different components. So you can use this data directly.
e.g.
ES_HEADER structure, you want to use plant field.
Simply use it as ES_HEADER-PLANPLANT

Hi,
I have requirement to get all the open orders(as in VA05) and all the open quotations( as in VA25) for a sold-to-party. Could you please let me know if there are any BAPIs or Function Modules for the same.
Thanks,
Surekha.

Hi,
Check if the below helps:
1. BAPI_SALESORDER_GETLIST for VA05
2. BAPI_QUOTATION_GETDETAILBOS for VA25.

BAPI or Function Module for F-53 and FBZ1

Hi Gurus,
I am currently executing two transactions F-53 and FBZ1. I would like to know if there are any read BAPIs or function modules that take BELNR_D(Document Number) and Company code and Fiscal Year as input and give the rest of the details I enter in these transactions like, partial payment, residual payment.
Kindly help.
Many Regards,
Sagar

Hi, Sagar:
Nice to see your thread here
No matter what kind of transactions you are using, finally, there will be a document posted in General Ledger Accounting, which is what you want. So to read the result, you can always try function module, like FI_DOCUMENT_READ.
Hope it will help.

I need to know thelist of bapi's and function modules used for transaction

I need to know thelist of bapi's and function modules used for transaction in order to use these FM or BAPI in reading some fields of equipment master and functional loocation.Can any one suggest me some methods...or do i need to write a report for the same.

Steps to find the BAPI/function modules used in a transaction
1) Find the package of the transaction thro' SE93.
For example the package for the transaction VA03 is VA
2) Go to Se80, key-in the package (say VA)
3) You can see the function modules under the folder finction group and
you can see the BAPI's under the folder Business Engineering-> Business Objects-> double click on the released methods of the Business Objects

In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

hello all
In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

Hi Swamy,
The differences between IDoc and BAPI are as follows:
IDOC
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system.
Idocs are processed asynchronously and no information whatsoever is returned to the client.
The target system need not be always online. The IDOC would be created and would send the IDOC once the target system is available (tRFC concept). Hence supports guaranteed delivery.
With asynchronous links the sub-process on the client can be finished even if the communication line or the server is not available. In this case the message is stored in the database and the communication can be done later.
The disadvantage of asynchronous links is that the sub-process on the server cannot return information to the calling sub-process on the client. A special way for sending information back to the client is required. In addition, a special error handling mechanism is required to handle errors on the receiving side.
IDOCs may be more changeable from release to release.
IDOCs are poorly documented.
BAPI
BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
BAPIs are called synchronously and (usually) return information.
For BAPIs the client code needs to do the appropriate error handling.
Problems with synchronous links occur if the communication line or the server is temporarily not available. If this happens, the sub-process on the client cannot be finished (otherwise there would be data inconsistencies).
Synchronous links have the advantage that the sub-process on the server can return values to the sub-process on the client that has started the link.
BAPIs are not totally immune to upgrades.
BAPIs are reasonably well documented.
Reward points if useful.

Sekhar

Is there any BAPI or function module to delete entries from a table (VBAK)

Hi Everybody,
this is my first thread in SDN...
my problem follows...
A report is be created that selects all sales orders created by e-Sales that are more than 20 minutes old and still have a delivery block:
tables:
VBAK     sales document: header data
selection fields:
VBAK-LIFSK      ≠     <BLANK>
VBAK-ERNAM     =     userID used by e-Sales / IVE
          (EP-BATCH / EAI-BATCH)
VBAK-ERDAT      <=     Current system Date
VBAK-ERZET     <=     Current system Time - 20 minutes
These orders should be deleted from SAP system.
This report should be scheduled to run regularly every 10 minutes.
my doubt : is ther any BAPI or Function module to delete entries from a standard table...if no what is the way to delete the enteries from a std table...
best replies will be rewarded....
regards
Reddy

Hi Vasanth ,
thanks for your reply.
i tried in the same manner what u mentioned.
but how to pass only one parameter to the functionmodule..
here in this case we have to pass only update flag as 'D'..
i did the same it giving dump..
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_TYPE', was
not caught and
therefore caused a runtime error.
The reason for the exception is:
The call to the function module "BAPI_SALESORDER_CHANGE" is incorrect:
In the function module interface, you can specify only
fields of a specific type and length under "ORDER_HEADER_INX".
Although the currently specified field
"INT_ORDER_HEADER_INX" is the correct type, its length is incorrect.

Standard BAPI or Function Module for FB01posting

Hi Experts,
My requirement is as follows.
Invoice details would be sent across from Middleware to SAP and for which I have developed a Custom Remote Enabled Function Module. The Function Module needs to post the data using FB01 Transaction.
I had planned for recording a BDC for FB01 and post the data, however, we are on the verge of getting upgraded from 4.7 to ECC 6.0. To avoid problems that we might face for change of screens in ECC 6.0, I would prefer using a BAPI or Function Module for FB01 posting, if available, instead of BDC.
Data coming from Middleware are as follows.
HEADER:
BKPF-BLDAT : Document Date
BKPF-BUDAT : Posting Date
BKPF-XBLNR: Reference (Invoice#)
BKPF-BLART : Document Type
BKPF-BUKRS : Company Code
BKPF-BKTXT : DocHeader Text
BKPF-WAERS : Currency
LINE ITEM:
BSEG-LIFNR : Vendor no
BSEG-WRBTR - Total amt -Debit/Credit -Vendor
BSEG-ZUONR : Assignment field
BSEG-EMPFB : Alternative Payee
BSEG-UZAWE : Payment Method Supplement
BSEG-ZTERM : Pmt terms
BSEG-KOSTL : Costcenter
BSEG-HKONT : GL AccountNumber
BSEG-WRBTR : Amount for GL
BSEG-SGTXT : Line item text
The Vendor Line Item would be one where as GL line items could me more than one.
Can any of you suggest me a standard BAPI or Func Mod?
Points will be awarded for valuable inputs.
Thanks to all!!!!

You can use RFBIBL00 program for FB01 postings. Go through the program help on how to use this program.
This program requires a file to be on application server in a certain format.
You may also refer the program RFBIBLT0 on how the file format should be.
Hope this helps.
Thanks,
SKJ

BAPI or Function Module for F-22

Hi I am working on one scenario. I am clearing the document using F-30 transaction in one company code and Posting the same document in other company code using F-22. I need to know whether it posts successfully or not using F-22 before I clear the document so that I can stop this from clearing. I can not do this simply using the BDC. Here I need a BAPI or function module to have a check whether it will post successfully or not using F-22 before I clear the document using F-30.
Please help me to find the right BAPI or Function Module here.
Thanks,
Ravi.

Hi Eswar,
BAPI_ACC_DOCUMENT_POST works only for 2 line postings. But we can make it work for one line by implementing BTERWBAPI01.
Here you will be passing ACCHD-GLVOR = RFST
ACCIT-BSTAT = S
ACCIT-BSCHL = 39
ACCIT-UMSKZ = F
ACCIT-ZUMSK = Z
could you please share the code that you have implemented in BTE?
please share the sample code that you have done for BAPI.Because I also have the same requirement for f-47.
Regards,
xavier.P
