hi,

append structure is used to add fields to standard tables where as

extension idoc -

---

mainly useful for us to add more fields as a segments in a idoc. i.e

material idoc can have more than one extension as it depends on the requirement. a segment is nothing but collection of fields. based on ur requirement we ll use different idoc types [idoc segment types] for an idoc.

if helpful reward some points.

with regards.

Hi Srini,

Append structure is used to more firlds to the standard table as for the requirement. Here structure is first cretaed and then appended to the standard table like VBAK , KNA1 etc..

But in extended idoc , if you want to include some more data and the container for that data (segment) is not available in the idoc , then you can include that field as segment and that segment will hold that data.

Thanks
