Hi,
Stocks(available\pickup) of each storage type in LQUA keep on changing , you can not use last movement data as a delta filed to fetch data to BW.
Instead , have a look at below points.
- create a virtual provider based on DTP (direct access)
- transformations
- create direct data access dtp, as generic data source's are enabled with direct access by default (data source-->change mode-->extraction tab-->choose direct access as "allowed").
- no need to run infopackage/dtp.
- then create reports.
- you can always match BW data against ECC , all you need to do is refresh the report when there is a change in ECC .
