An LUW is a logical unit of work i.e.it can be an individual document, a group of documents from a collective run or a whole data packet from an application extractor.

ex: In direct delta each and every changed/new document is treated as a luw where as in queued delta some 10000 new/changed documents are treated as a luw.

i.e.,

data is transferred in terms of LUW to BW.

Hi Harry,

As stated earlier LUW is Logical unit of Work.

For example take SD

When their is some activity on the document like New /Changed

so lets consider it as one unit.

When it comes to delta update method.

Direct delta- each unit is transfered directly to Delta Queue. so in this method LUW is nothing but a change in the document on SD.

Queued Delta- when some change occurs as i told earlier that unit will be collected in Extraction Queue. and here we don;t consider a single unit as LUW but we consider 10,000 units as one single LUW.

Unserialized V3 UPdate.- the same the unit (i meant the change which happened on the SD document) is first stored in UPdate Table and from their it is transfered as LUW to Delta Queue.

so LUW in Delta queue means different in different update methods.

like one single change r multiple changes combined to one (LUW).

Thanks and Regards
