How does conversion work?

[#1]

Hello all,

Just wanted to clarify how does conversion process work? Can you explain situations where it directly picks up from legacy system and in which situations Excel Spreadsheet is required. I appreciate your it.

Thanks,

Hi JEss,

In general SAP terms data conversion is the process of migrating data from one system to another, e.g. from legacy system to SA. So the process is generally following:

1. Obviously, data format, structure and values in legacy system may differ from SAP system. To make alignment you have to do mapping between legacy system and SAP data requirements.

2. Then make data transformation from legacy data into SAP accepted data. It can be done using Excel, legact system script, or even SAP (e.g. in LSMW). Project team has to decide what is the most easy and optimal way.

3. Finally you upload data to SAP. You can use batch input (BDP) or LSMW. If you decide to use LSMW for data transformation then all data mapping will be done during data load.

Cheers,
