Optimizer creating high production plan in few buckets

Question

Hi,
Optimizer is creating high production plan in few buckets though there is less demand.
Findings
1. system in not preplanning to cover future demand.
2. there is one resource used by three different products for one product optimizer is doing excess planning while it is showing supply shortage for other products.
3.If I again take optimizer run for all the three products at all the location system is giving correct results (all receipt elements in line with the demand.
Now i need to understand the reasons why optimizer gave high production plan in last run ?
Regards
Abhi

1. system in not preplanning to cover future demand.
check storage cost and penalty cost , i think storage cost is more then penalty cost.
2. there is one resource used by three different products for one product optimizer is doing excess planning while it is showing supply shortage for other products.
if you run all three one by one it plan only first product on that particular resource, if you run all three same time system will plan according to the cost optimisation logic, that means it checks all cost and calculate which product needs to be manufacture on that resource and how much.
you can check the log of snp optimisation run in
