Doubt regarding data coming from 2LIS_03_BF extractor: Use of BWCOUNTER
In 2LIS_03_BF extractor there is a field Unique Identification of Line Item (BWCOUNTER), which has to be taken as a key. In my development i am not taking the data directly to a cube. i want to take it first to one inbound DSO, then an outbound DSO and finally into a cube.
Can anyone tell me the importance of the field BWCOUNTER. Should i include this object as a key in inbound DSO, outbound DSO and the Cube. Or can i just include it in inbound DSO and avoid it in other two. In SAP business content cube for 2LIS_03_BF i cant find this field as a key. Also another OSS note says that i will have to include it if i am using an ODS. So i am confused till which level of infoproviders i should take this key.
