Hi Experts
my understanding is that
2.1)SS* is calculated via a local formula (row 33,33,34)
3.we perform a normal dynamic lot size procedure in period T (50) always using
3.1)normal coverage span CP defined by SUBPERIODSOFSUPPLY (2 for period T)-->output Additional Lot size (row 25)+
3.2)using SS* instead of SS -->output(row 34)+
3.3)standard dependent demand of the period -->output(row 17)+
3.4)standard independent demand of the period -->output(row 18)+
3.5)projected stock(t-1)-->output(row 24 of (t-1))-
In my case the should be
ND =Additional Lot size (4700)+ SS*(14000)+ DD (100) + ID(0)- ProjStock[t-1](100) resulting in 18700
but I have 14000 .Why?
Request clarification before answering.
Hi,
IBP Calculation is correct because demand horizon do not overlap each other, their calculation is sequencial for demand horizon
For W50 there will 2 calculation
1. 2 Periods will SUM demand from W51+52 = 4700
2. 6 Periods will SUM Demand from W1+W2+W3+W4+W5+W6 = 9300
So total 4700+ 9300 = 14000.
Thanks

Hi Girish,
The calculation about lot size procedure 5 seems very confusing even in the below SAP Help Portal Link.
In the example provided in the link, there is no net demand in period 2 and 3. I don't understand the logic why there is not net demand.
I suspect the usage of supply algorithm other than Infinite Heuristic.
Thanks and Regards,
Revan C
