These two tables are related in 1-N relation(VBAP:1 and VBRP:N).
Also in some cases there are no entries in VBRP(AUBEL and AUP) for some entries in VBAP(VBELN and POSNR).
I am creating an Olap to find all entries in VBAP (VBELN and POSNR) which does not have related data in VBRP(AUBEL and AUP) but they dont show up in olap. If i remove the VBRP columns from olap then they show up.
