Problem in datasource 0MAT_PLANT

Hi Gurus,

My requirement is to extract "standard cost changes" into BW master data 0MAT_PLANT which is feeded by SAP standard delivered datasource 0mat_plant_attr which doesn't have this field so I have enhanced datasource with this field but changes to standard cost for a given material/plant is extracted to BW when there is a change to other delta-enabled fields in 0mat_plant_attr datasource but my requirement was to trigger standard cost delta changes to BW without changes to attributes so I have gone for generic extractor through View by ALE Delta enabled i.e. the generic datasource(Uses flexible update infosource) thru View will extract only deltas into BW if we need to go for any new records or full upload we have to load them thru standard datasource(Direct update infosource) but now my doubt is as I load huge amount of data daily:

1)There will be any issues like performance wise or anyother when i load millions of records thru this view.

2)Is the data from the standard datasource and generic datasource are consistent as one is direct update and other is flexible.

Would anyone please explain in detail about this. I appreciate it in advance and I gaurantee of award points.

Thanks and Regards

    1. Peformance - Business content ( Function Module based ) extractors are always better than eneric ones - and a view holding millions of records will be lesser in performance compared to a business content datasource

    2. There is a possibility of inconsistency since the deltas for both data sources are based on different logic - if you do a full update , then it shouldnot be a problem - provided that the business content extractor also extracts from the same tables and no extra logic is involved..
