    HI

    in std sap, they maintianed as 100 in planning horizon.

    This planning horizon specifies the period for the "Net change planning in the planning horizon".

    In this kind of net change planning, only those materials that have undergone a change that is relevant to MRP within the planning horizon ( say 100 days ) are included in the planning run. Such materials receive a net change planning indicator in the planning file.

    it means " where a planning file entry is made for the net change planning in the planning horizon. The planning horizon is calculated in workdays "

    so for planning file entry is made for the net change planning in the planning horizon for 100days.

    You can change as per your customer reqmt.

    basically the planning fiel is calculated by :

    The length of the planning horizon should include at least the following:

    the period in which sales orders are received

    the delivery periods

    the total lead times of the materials

    Hi According to me Planning Horizon is the number of days we use in MRP Run. This we define in OPPQ as 100 days.The system only plans materials that have undergone a change that is relevant to the planning run within the period which you defined as the planning horizon.

    In your case if you want to change the planning horizon to more than 100 days you can cheanged it.

    Anway we will wiat for oiur experts reply too.

    Cheers,

    Dear Srinivasan,

    In my understanding in most of the cases the next 3 months requirement will be considered during MRP run with processing key

    as NETPL during MRP run and so the system considers only the requirement that falls within this 100 days for the procurement

    proposals and leaves off the remaining period's requirement.

    Say for a plant the planning horizon is defined as 100 days in OPPQ and for a material under this plant,there is req for

    August,September,october and november for 1000 quantity in each month and the stock is 0 and if you run MRP with

    NETPL,you will be able to see the planned order's getting created only for the Req till october (3 planned order's will be

    generated)and if you run with NETCH the system considers all the requirement's that fall within and outside the planning horizon.
