IDocs and Multiple Records

[Former Member]

Ignorant newbie here. In migrating legacy data to an R/3 system, one approach seems to be to massage the data into IDoc format and ship it to R/3 for processing by some BAPI_xxx_CREATEFROMDATA BAPI.

I have a tool that can be changed to write IDoc formated data out to a disk file.

I am unclear on whether an IDoc can contain the data for only one record or a whole bunch of records. Or maybe I should be asking whether the disk file I produce can contain multiple IDocs (header, segments, header, segments,...).

Also, once I've produced the file containing the IDoc(s), what do I do with it; does DX Workbench handle such things?

Hi,

1) Each IDoc# contains data to process single transaction. But it contains with mutiple rows with segments data that to process necessary application data that required to create like Sales order creation/change , Material master creation/change.

2) your disk file can have any no# of idocs.

Your DX workbench(data migration tool) will process all the IDocs from file by considering one idoc# at a time.

It is as simple as like how your BDC program works inorder to post your orders that reading from file.
