Synchro Perform does not provide value or function of VOWD
VOWD (L) = Budget Cost (J) x Percent total progress(M)
Total Budget Cost (J) = Unit Rate (F) x Qty (I) x Discount (H)
Perform does not provide "Unit Rate" or "Discount" fields; and also NO resource pre-assignment to activities for progressing.
So, the computation of VOWD cannot be achieved.
