Step-by-Step approach to write a BDC program

BDCs are one of the most important objects of an implementation project and they usually give shivers to young (junior) ABAPers. They are used to populate the R/3 database with legacy data. BDCs are an efficient way to populate large amounts of R/3 data using minimum resources and time. BDC programs also (must) ensure that data populated is accurate as the whole application/module runs on that data.

Before starting to code the BDC program, it is a must to understand the transaction into which data is to be populated. Flat files with data need to be studied well for the order, format and accuracy of data. The best way to do it is to have a functional consultant record the transaction (using SHDB - Transaction recorder) entering all the data that needs to get into the transaction. Another way is to do the recording ourselves by entering all the data given to us in the flat file. Once the recording is ready with a simulation of the transaction to be populated, the ABAPer can start writing code to populate the transaction.

Here is a sample BDC for uploading Material Master data (MM01). It gives the users options to choose the upload method (Session/Call Txn), and also accepts files in DAT, XLS, TXT format, with header lines. Feel free to use it. What's more important to me is your suggestions. So do write back :)

* Description : Material Master (MM01 BDC) *
* Developer : Karthik Potharaju *
* Package : ZKAR *
* Description : *
* *
* PROGRAM FLOW *
* 1. Read input file *
* 2. Check the mandatory fields and if any one of them is missing *
* move the record to error file. *
* 3. Fill the bdcdata and call MM01 transaction *
* 4. If any errors format the message and send it for reporting *
* 5. If any errors, it downloads the error file *
* 6. Based on user input, this program does the following *
* a) Call transaction and in case of errors add to a session *
* b) Create session *
* 7. Display the Audit report *
