What is the difference between regenerative plan and net change plan. If you check through the system both the thinhs does the same functionlaity. I am not able to find out what is that regenerative plan can do and net change plan can’t do and vice versa. Regards abhay
In net change planning, items only participate when demand or supply changes or when planning parameters change such as safety stock, routing , BOM.
Hi Abhay The net change plan will only look at those items where significant changes have taken place since the last regeneration, whereas the gross requirements assesses everything from scratch. The help on the net change sums it up nicely:
quote:
When you calculate a net change plan, the program plans only for those items that have had the following types of changes to their demand-supply pattern since the last planning: 1. A direct change in the demand requirements for the item. This could be a change in a forecast, sales order, purchase order, production order, or production order component line, for example. 1. A change in the standard data and/or planned supply for the item. This could be a change in the BOM or routing, the definition of safety stock or reorder point, or unplanned inventory discrepancies, for example. The reason for calculating a net change plan, as opposed to a regenerative plan, for example, is to save time and system resources. It is not necessary to replan items whose demand-supply pattern has not changed since the last planning.
Morning Gunther Obviously cutting and pasting the help file cost me a vital few seconds - so you win this one! [:D] How is the weather?

overcast and nippy, but it is England in mid-October, so its fantastic [:D]
Dear friends, I would like to mention that if there is any change in demand, than in planning engine if I run net change plan or regenerative plan, the outcome is not different. I repeat if I change the demand as mentioned by you people say I change the quantity in sales order. Than I outcome remains same whether I run net change plan or regenerative plan. The only thing which I could make out is that in net change plan, system will be much faster otherwise there is no difference . Otherwise please let me know that if I change the demand or supply I will get some particular outcome only in case of net change plan and not in case of regenerative plan or vice versa. Your comments please. Regards Abhay
Hi Abhay You are correct in your change of demand, but if you are running this across thousands of items with BOM’s then the processing time between a net and gross will be significant.
Hi Steven, So it is only the processing time which will be different otherwise there is no difference between net change plan and regenerative plan as far as functionality is concerned. Abhay
Hi Abhay There is one difference I suppose that you should consider but it is all lumped in with the processing. When you run a full regen, it will automatically delete all currently loaded planned orders and replan them. whereas the net change will only do this if the demand alters.
Dear All, I tried that but again there is no difference. What you are talking about will also depend on the requisition method. Because I tried before depening on the demand and requisition method system sometimes cancel the order and in other cases change qty in the existing production order. I would also like to have one more inputs , if I had reported some activity on release production order than any change in demand or supply does not affect this production order. Can you confirm this. Regards Ajay
Hi Abhay As stated previously - any change in demand will mean the same results from a net change or a gross requirements run - so if you are changing the demand and ecpecting to see differences you will not. Would you mind explaining this bit:
