I have to activate couple of SCM cubes in BW . Right now I am in the stage of gathering requirements .
And I have identified 4 legacy tables which cover these reporting requirements . R/3 installation and configuration is going on along side.
I am trying to get a mapping from the legacy fields to the R/3 fields.
Now my confusion is , I have been asked to look at some SCM business content . I am thinking once I do the legacy mapping , i will be doing the mapping from the r/3 to the bw fields.
q 1. How do I know which field in R/3 refers to which field in BW. Because in R/3 Material is called as MATNR and in BW it is 0Material. I am just picking a simple example .But what is the way to map some customised fields.
q 2 . I am thinking the R/3 system would have been customised for the company like for example telecommunication. Then these fields will not be provided by the BW business content , how will I map these fields.
I have some more questions but I would be posting them in a different post , so that assigning points would be easier.
Thanks in advance
