Check Material Availability - Production Order CO02

Hi friends,

I have 2 materials (3250002386 and 3250002389) of the same type and same configuration in the master data, both have stock in the 2029 warehouse, but only the 3250002386 material is not released in the "Check Material Availability" CO02. I attachment the document with the data.

Can anyone help me what may be occurring with the 3250002386 material ?

    could you include a screen shot from CO09 for both materials and also show the scope of check. My guess is that some other order has that material reserved.

    Hi Fabricio,

    After the availability check is done, can you send the screen for the availability check logs. Normally errors with description is logged in availability check logs.

    Are the reservations you are seeing for open process orders, or is there a chance that they are issuing less than the reserved quantity to the process order but not setting the final issue indicator when the GI is processed for the process order. There is also an clear reservations indicator when the order confirmation is done. If that's not done, and the order status hasn't been set to TECO then the system will consider those partial reservations as still open and could be tieing up the stock.

    If that's not the case then I'd check the order type dependent parameters (COR4). If the Reservation Relevance is set to 3 (immediately) then a process order will create a reservation as soon as the order is created. I'd test it to be 100% sure but I'm almost certain that a subsequent order would not consider that stock as available even if the start date of the second order had an earlier start date. If you set it to 2 (from release) then the reservation won't be created until the order is released. the down side of that MRP won't see the dependent demand from an order until it is released

    I have identified the problem, my rule wasn't considering the security stock.
