INTERVIEW QUESTIONS SAP R/3 SAP MODULES DETAILS

Question: Of all the methods used for data migration like BDC, LSMW , Call Transaction which one is used most of the time? How is the decision made which method should be followed? What is the procedure followed for this analysis?

Answer: All the 3 methods are used to migrate data. Selection of these methods depends on the scenario, amount of data need to transfer. LSMW is a ready tool provided by SAP and you have to follow some 17 steps to migrate master data. While in BDCs Session method is the better choice because of some advantages over call transaction. But call transaction is also very useful to do immediate updation of small amout of data. (In call transaction developer has to handle errors).

Bottom line is make choice of these methods based of real time requirements.

These methods are chosen completely based on situation you are in. Direct input method is not available for all scenarios; else, they are the simplest ones. In batch input method, you need to do recording for the transaction concerned. Similarly, IDoc, and BAPI are there, and use of these need to be decided based on the requirement.
