SNP heuristic

Question: I have created a small cupply chain 1 product , 1 sales location and 1 factory.
All the lead times in the transportation lane are zero
Now suppose I have a demand of 100 in week 1 ( there is no other demand in entire horizon aprt from this) and I run the SNP network heuristic for above network the system satisfies the demand in week 1 by producing 100 in Week 1 but then plans production of 100 in each of future bucket despite the fact that there is no demand.

anyone faced this behavious earlier? any solutions

Answer:
There are many factors which might be resulting in this behavior
(1) Check the total demand on the factory.
Is the demand visible in the factory only in the first week or do you see it in all other weekly buckets

(2) Check if there is any safety stock requirement in the factory

Let me know the answers and I might be able to help you.
