    Hi

    I need to perform Forward scheduling as first by default? If it is not possible /illogical why?

    If you really understand the meaning of backward and forward scheduling you will know why it is illogical to have only forward scheduling as default as first

    Enclosed here with the threads which explain you about forward and backward scheduling

    Forum post in ERP - Sales and Distribution (SD) General: Back scheduling

    back-scheduling

    Forum post in ERP - Sales and Distribution (SD) General: backward scheduling

    backward-scheduling

    Please note by no way you can make system to perform forward scheduling first by default and that is illogical

    If backward scheduling fails by customizing in t code OVLY you can control the system by not performing forward at all

    That is only backward and stop after that

    Hope this threads clarifies about forward scheduling and backward scheduling

    Regards

    Hi,

    I dont think its possible. The reason which i think is

    1. Customer date which is the required delivery date must have been given the priority. So depends on that date all the other activity should be carried out.

    2. By Forward scheduling you enforce the date to the customer, which is not possible in general business scenario. As there is general Proverb : Customer is King.

    By the way this is my thinking. Other experts views are welcome.

    So based on that Backward processing is default.

    Thanks,

    Raja

    Hi Ishikesh,

    It is not possible to perform Forward scheduling as first by default. By default system performs backward scheduling and if the material availability date goes in the past or if the material is not sufficient then at that time system performs forward scheduling.

    But you can perform backward scheduling only if you want.

    Backward scheduling is performed 1st by default so that system can calculate all the times (transit time, loading time, transportation lead time and pick/packing time) and confirm whether material can be delivered on Customer's requested delivery date.

    Therefore, system takes the customers req. del. date as an input and perform backward scheduling 1st. And forward scheduling is performed ONLY if date is in the past or qty is not confirmed.

    Hope you will understand by this

    regards,

    Sagar
