Dear Experts,
We got a situation: Management wants to poll the attendance data to SAP ECC , attendance data is captured through a bio-metric device and stored in the DB2 on legacy system AS/400. We are proposing to use SAP XI to poll the data from legacy system to SAP but some of the developers are proposing to do the same using DDM (a feature of AS/400). Since our SAP ECC is also based on AS/400 and DB2, developers say that is would be easier and better to transfer data using DDM from Legacy system to ECC (in this case direct database access will be possible to and fro) which is we think in no way a good practice. Another logic they come up with is, using XI would take more time and due to this there will be some delay and it will lead to count the delays in SAP MRSS.
Below is the detail of environment:
Legacy System : On AS/400 and DB2
SAP Systems: SAP ECC on AS/400 and DB2
SAP PI on Windows Server 2008 and MS-SQL 2008
Please share your suggestions with us about the ideal solution.
Many thanks,
SUJIT
