Hi,
Ok you can do like this.
a.) take union of both the scripted views.
b.) In union, check if KDAUF = INITIAL. Take one more projection view having table VBFA and then join your UNION having blank KDAUF with VBFA with common fields ( with keys ) and get VBELV and POSNV,.
c.) In this join , check again if KDAUF is initial, put this resultset in separate projection and join the same with LIPS and get your output.
I hope you understood my point.
