Month = planned production past due + project on hand past due
= 62.501 kardus + 2.465 kardus = 64.966 kardus 5. Projected on Hand 2
nd
Month = planned production past due + project on hand past due
= 62.501 kardus + 2.465 kardus = 64.966 kardus 6. Projected on Hand 3
rd
Month = planned production 1
st
