I am new to the BW-GL extractors. We have a requirement where we have to extract some of the fields from BSEG table to BW. The standard fields from BSEG that I require are already in 0_FI_GL_4 extractor. But the problem our BSEG table is enhanced with some Z_* fields and these are required in BW as well. I tried to do this by creating the include CI_BSIS and including the Z_* fields but when I ran the rsa3 extractor I didnt see any data in the Z_* fields. Can any one please tell me how to do this ?
