As my remark when sending you RAP
#4. This RAP2014 is based on production plan of DMVN -->Delivery schedule (ETD at your side) may push advance around 1 month depend on transportation leadtime.
It means that Require each month in RAP is production plan at DMVN. (ETA DMVN)
PO from DSTH shows supplier delivery date (ETD Supplier)
=> transportation leadtime leads to diffirence between RAP2014 and PO from DSTH
