Availability check box at schedule line level and requirement class level

Hi All

What is the significance of availability check field at schedule line level and requirement type level.

If I remove the check box at schedule line level, then there won't be any availability check carried out in the sales order, even though in requirement class it is checked. Is it for doing availability once the requirement is passed to MRP...

In make to stock scenario, no availability check is active at schedule line level.

scenario 1. stock is 0 in plant, when i place an order for 10 quantity, does system give any confirmed quantity on so and so date...or the confirmed quantity will be zero or as there is no availability check carried out, it confirms 10 quantity on customer requested delivery date and the time of creation of delivery, it gives an error message stating zero quantity is available. which one is correct in all the above.

In make to order scenario, no availability check is active at schedule line level.

order was created for 10 qty, as there is no availability check active, does the system give some date based on the lead times maintained in the material master or not?

Regards

Sree

    Hi sreekar

    The significance of availability check at schedule line level is to determine weather availability check and TOR should be carried out for sales orders or not.

    If you remove check box at schedule line level , availability check and TOR wont be carried out at sales order level.

    Coming to the scenario you said , make to stock , i think the availability check you are using is 01 make it 02. which is planned requirements. and stratergy group as 10. in MRP3 view in MMR. .

    as the availability check u have put 01 & stratergy group as 10 availability check doesnt carry

    coming to the scenario 2 , if the stock is 0 in plant and if you create a sales order, then the confirmed quantity should be 0 and that particular order will go to backorder processing.

    sometimes it confirms the ordered quantity as the confirmed qunatity, and it gives a confiremed delivery date on which the stock is confirmed , but that date is a tentative date.

    all these unconfirmed orders will go to backorders. once the qunatity is confirmed automatically , delivery date also will be done

    Coming to scenario 3 , when you create MTO order there will be availability check checked at the schedule line level. can you tell wat is the schedule line you are getting is it CP or ND?

    for schedule lines , ND - no availability check will be there , PD - availability check will be there

    Note: plz check 1st the availability check you have entered in MMR , if it is 01 make it as 02. and then run these cycles.

    Reward points if useful and if Any queries let me know
