Method for Downloading Huge Data from SAP system

Hi All,

we need to download the huge data from one SAP system & then, need to migrate into another SAP system.

is there any better method, except downloading data through SE11/SE16 ? please advice.

I have already done several system mergers, and we usually do not have the need to download data.

SAP can talk to SAP. with RFC and by using ALE/IDOC communication.

so it is possible to send e.g. material master with BD10 per IDOC from system A to system B.

you can define that the IDOC is collected, which means it is saved to a file on the application server of the receiving system.

you then can use LSMW and read this file with several hundred thousand of IDOCs as source.

Field mapping is easy if you use IDOC method for import, because then you have a 1:1 field mapping.

So you need only to focus on the few fields where the values changes from old to new system..
