Automatic Purchase Requestition creation for item category "L" (Stock Item)

Hi All,

I have a query,

When components are assigned to a maintenance order whose item category is "L" (Stock Item).

As soon as components are assigned a reservation number is generated by the system immediately.

Now my requirement is,

for an item category which is "L" (Stock item), while I am saving / releasing the order, system should do availability check and based on the qty available it should automatically generate reservation (in case of full qty is available) or a purchase requisitions ( in case of non availability).

Is this feasible? If so kindly let me know how it can be done.

Currently in my case,

i am getting a reservation number for an an item whose item category is "L" but the stock qty is "zero". System should have ideally generated a purchase requisitions number for such a case because of actual available qty being "zero"

Is there any setting called "reservation time" so that after checking the availability of that item system decided whether a reservation number should be generated or a purchase requisition number?

Thanks and with best regards

Kannan J

    hi kannan

    In SAP "L "is stock item ie some quantity is already there, hence it will not generate PRs for that eventhou the commited quantity in less the requirment.So once the material has gone below the safety stock MM people will run the MRP run which generate PRs for the low quantity material. idont think there is another possibility for creating PR for stock material.

    you can make settings that if material is not available then you can reject the the release

      Hi Thyagarajan,

      I wud like to share with you a content of SAP documentation which is as follows:

      "You can plan materials that are required to execute the task for each operation in the maintenance order. The materials can be bill of material components for the reference object or freely assigned material.

      <u>The materials that you plan for the maintenance order will be reserved in the warehouse, if they are kept in stock. You can set the reservation time in your system using the customizing function. In customizing, it is decided for each order type, whether the system should make the material reservation effective or generate the purchase requisition immediately or only when the order is released.</u>

      An availability check can be called up when components are assigned in the order.

      An automatic availability check is performed when the order is released. The order can also be released if there is no availability.

      A material provision list and material withdrawal slips can be printed together with the order papers.

      Planned goods issues are entered with reference to the reservation, such as reservation number, unplanned goods issues with reference to the order number.

      The goods issues entered appear in the document flow of the order."

      Now with this, is there a way out to resolve the issue?

      Best Regards

    Shiv Chand,

    Ideally you may want to make sure that the requirements that are generated for the stock materials are satisfied by the MRP runs and sufficient stock is available to satisfy these requirements.

    However if you still want to generate PR for componets when there is no stock (For a material type identified as a stock material), you could accomplish the same with the help of the user exist at the component screen.

    There is a exit available to identify and tweak the item category on the component screen of the order when the component is inputted and override the settings made in the config for the material type.At this juncture in this exit, you could manually check the stock of the material at the respective Org levels and also look at the delivery dates for any open PR/PO and if you would still require PR to be generated, then you can switch the Item category to "N" for the stock material.The moment you do this, that specific material would be treated as a"NON-STOCK" item and system would force the Purchasing tab to be populated with the madatory fields to enable the creation of PR.

    Hope this helps.

    hi kannan

    As per the SAP help the time mentioned is for generating the reservation,ie either the material specified in the maintenance order will be reserved on relase or immediately or never .

    system will not generate the missing parts ( stock item ) PR automatically. you can check the availability when release or saving the order depend upon the customization settings

    for this case only in MM master record stores person will maintain Reorder point,ie whenever the stock comes below this point , the material will go to MRP planning where purchase requistion will automatically generated
