How To Post SAP FI Document Using BAPI


The accounting documents record changes in values in a company code arising from accounting transactions. They consist of one or more line items (postings), each of which represents an individual transaction posted to an account.

When posting an accounting document, the SAP system updates the transaction figures in the accounts to which the document is posted.An accounting document is a representation within the SAP System of the document (for example, an invoice) that triggered the posting.

BAPI ‘BAPI_ACC_DOCUMENT_POST’ acts as the interface between your code and standard transactions FB01/FB50.

This document explains the various steps involved to post a FI document using BAPI ‘BAPI_ACC_DOCUMENT_POST’ from an excel file.

This is helpful to SAP Technical consultants as it gives the details of all the required parameters and data in document posting and validation to check if the GL account in which we are posting amounts is present in SAP database.

Transaction code for FI documents are FB01/FB50(Create), FB02(Change) and FB03(Display). In one document, more than 999 line item cannot be posted because BAPI can post up to 999 lines in one document.

The file should be balanced for the document to be posted i.e. credit amount and debit amount should be equal. In FI, header table for document data is BKPF and line item table is BSEG.

To Post FI Document using BAPI, we need to follow this step-by-step procedure. The steps are :
  1. Upload data from excel file into an internal table using FM ‘GUI_UPLOAD’ as explained in subroutine UPLOAD_FORM_EXCEL.
  2. After we upload excel data into an internal table we need split the data into field patterns into header data and line item data as explained in subroutine ‘SPLIT_INTO_RECORDS’. This splitting is done according to my file format. In header data in the file in line no.2, posting date and header company code. That is why I have used case when 2. And all the other information is present at the lines as described by CASE statement. Line item details start from line number 14, that’s why LOOP AT t_upload INTO w_upload FROM 14is used. User can split the data according to their file format.
  3. After the splitting, loop at the line item table and validate the GL account numbers. If the GL accounts are valid, Populate the line item data into BAPI GL and currency tables otherwise append that GL account number into error message table. This is explained in subroutines ‘VALIDATE_GL’ and ‘POPULATE_BAPI’.
  4. In case of intercompany postings, in which line item and Header Company codes are different. Find out line item company code currency key and compare if the line item currency key and header currency key given is same or different. If these are different then we need to populate ‘EXCHANGE_RATE’ field of currency table if it is given in the file. Otherwise BAPI itself will fetch the exchange rate between 2 currencies and do the conversion.
  5. Above step is required because a document is posted in 3 currencies document currency, company code currency and group currency. In case of the intra company code postings all the currencies are same so the amounts are same In all3 currencies. But in case of inter company code postings the currencies are different so the amounts are also different. Due to this we need to give and exchange rate base on which the BAPI will convert the amounts.
  6. Next step in document posting is to check the data using BAPI ‘BAPI_ACC_DOCUMEN_CHECK’. If this BAPI do not return any error message, go to next step otherwise display error message given by BAPI.
  7. Post the document using BAPI ‘BAPI_ACC_DOCUMEN_POST’. Check for sy-subrc, if initial; commit the work using ‘BAPI_TRANSACTION_COMMIT’. This step is explained in subroutine ‘POST_DOCUMENT’. While providing header data in W_HEADER work area do not provide OBJ_KEY, OBJ_TYPE and OBJ_SYS, these are automatically populated by BAPI.

Summary

This document explains the various steps involved in FI document posting from excel file. Main steps involved are uploading and splitting data into internal table, Populate data into BAPI tables and call BAPI to post the documents and committing the transaction. A sample source code is given for the references.

Note : In case of intercompany code postings, if the exchange rate between 2 currencies is given in the file, programmer should pass only the exchange rate given. Currency value conversions will be done by the BAPI. Also Field status group configurations of GL accounts are not considered by BAPI as it is bypassed by BAPI, but these are considered when doing posting using FB50.

How To Defining and Implementing Business Add-ins (BADI)


Business add-ins (BADI) are enhancements to the standard version of the system. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery.

Two different views are available:

  1. In the definition view, an application programmer defines exit points in a source that allow specific industry sectors, partners, and customers to attach additional coding to standard SAP source code, without having to modify the original object. 
  2. In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard solution, if one is available. 

Steps for Defining BADI

Go to transaction SE18 and create a BADI Definition.










Enter the description of the definition. The name of the interface will be automatically proposed.
   










Save 













Double click on the interface  YIF_EX_H387_GET_MATNRDATA .  Enter the name of the method you want to create. 










Click the Parameters’ pushbutton to create parameters for the method. 









Save and activate it. 

Steps for BADI Implementation

This can be done in any of the following way: 
(a) On the menu bar of the initial screen of SE18 -> Implementation -> Create. 
















Enter the Implementation name. Press enter

(b) Or go to T.code SE19
















A popup window will ask you for the definition name. Enter the name of the BADI definition which you have created. Press Enter.  















Enter the description for the implementation. Then save and activate it. Double click on the method name. Write the following code. Save and activate it











Now create the following code, using the created BADI  




















Note: The above example is Single implementation. For multiple implementations, define an add-in and select the Multiple Use checkbox from the Attributes tab. 














We can differentiate between single-use and multiple use Business Add-Ins. The distinction is based on the procedure or event character of an enhancement. In the first case, the program waits for the enhancement to return something, usually a return code. 

A typical example could be a benefit calculation in HR. Depending on the implementation, alternative calculations can be executed. With multiple use add-INS, an event that may be of interest to other components is processed in program flow. 

Any number of components could use this event as a “hook” to hang their own additional actions on to.  

Note: The system does not check whether the class or method specified in BADI implementation actually exists. If a class or method does not exist, a runtime error occurs when using the function in the formula builder.

SAP Project Implementation Phases


SAP Project Implementation is one of the components of Project Management and required a great degree of project related Knowledge such as Project Management, Change Management, Risk Analysis and Review Programs.

Accelerated SAP (ASAP) is not only a SAP implementation solution but it also supports a comprehensive project plan. Like Project Management, ASAP Methodology also integrates several components and comprises of MS Project templates providing complete work breakdown structures and resource assignments.

SAP Implementation Phases 


Project Preparation Phase – As per Accelerated SAP (ASAP) methodology it is the First Phase of SAP Implementation. During this phase, following components are discussed and documented:

  • Initial Project Planning 
  • Project Procedures 
  • Project Team Members & their Training 
  • Project Kickoff 
  • Technical Requirements 
  • Quality Check 

Business Blueprint Phase - In this phase, a detailed study of business processes and business requirements are undertaken by the Project Team members. This is the phase where Project Team Members interact with respective Core Team Members or Process Owners. The entire requirements gathered during this phase are documented as Business Blueprint. During this phase, following components are discussed and documented:

  • Project Management 
  • Organizational Change Management 
  • Training 
  • Develop System Environment 
  • Organizational Structure Definition 
  • Business Process Analysis 
  • Business Process Definition 
  • Quality Check 

Realization Phase - In this phase, all the business and process requirements are implemented as documented in Business Blueprint. SAP R/3 system is configured step by step in two work packages, Baseline and Final configuration. How these configurations will be done and how it will be tested.

  • Baseline Configuration and Confirmation 
  • System Management 
  • Final Configuration and Confirmation 
  • Development of external Programs & Interfaces 
  • Unit Testing & Documentation 
  • Final Integration Test 
  • Business Scenarios & Process Documentation 
  • End User Training & Documentation 
  • Quality Check 

Final Preparation Phase - During this phase, following activities are discussed, completed and documented, successful completion of these activities leads to transition of all configurations settings to live R/3 System

  • System Management 
  • Stress & Volume Tests 
  • Cutover Strategies & Plans 
  • End User Training 
  • Quality Check 


Go Live and Support Phase – This is phase where all configurations/customizations are transported to live production operation and business starts all its activities in the SAP R/3.
During this phase, all the problems/issues related to hardware, network, operating system, database, training, and application system are addressed by the project team members and they help the end users in achieving their day to day task/assignments. This phase is further divided as:

  • Application Production Support and Maintenance 
  • Project Implementation End 

Continuous Improvement Phase – Towards continuous improvement and to overcome the organizational, business & technology changes the followings are covered under this phase:

  • Post go-Live Support 
  • Improve System performance 


ASAP is SAP’s solution to effective project implementation and management. It is divided into 5 major phases namely:


  1. Project Preparation 
  2. Business Blueprint 
  3. Realization 
  4. Final Preparation 
  5. Go Live and Support
