restriction on reservation in maintenance order

Jan 26, 2018 at 07:10 AM | 155 Views

Hi experts

I want to put two different error message on material reservation create through maint. order when-

a) no stock available and b) if stock available is less than reqd. qty.

I think I should use the tables MARD and RESB, further my query is which User exit /BADI is suitable for this.

Kindly suggest.

    Firstly, you can have the Reservation creation during Release of PM Order. Further, you can configure the Availability check in such a way not to release the order if there are some missing components.

    You can do the setting in the mentioned configuration with option "2 - Check availability during order release".

      I worked this set of requirements about 10 years ago with a team at a large client. We reached the same point that Mr. KD and Mr. Goyal reached: Avail. Check can produce an error and prevent Release, but when the Order is already released, development is needed to produce an error. Trigger off of the Warning for Availability Check, when Order has REL.

      We had the development activate a User Status that blocked the Goods Issue. That way, a Senior Person with authorization for the User Status could allow the GI to this Order, instead of an order previously planned to use the stock.

      @Paul, the Avail. Check is to the Matl. Req. Date on the Order, usually day before the Basic Start Date. If the date is in the future beyond the replenishment time on the Matl. Master, the error will not occur. MRP will fill the requirement, as you suggest.

    Checking tables MARD and RESB is in general not sufficient to know what is available. Checking MARD just tells you what you have in your storage location in SAP. But there is quite a difference between stock on hand and available stock. I tried to explain it in this blog: Unrestricted use stock not equal to available stock

    Use BAPI_MATERIAL_AVAILABILITY to know what is available.

    But isn't the availability check not already executed automatically in a PM order?

    Configured availability check does not stop, it only gives the info message. I want to restrict to create reservation if No stock or stock avl but already reserved.
