Component item category "N" - Stock

Hi,
We use item category "N" and procurement type Purchase Requisition for Network" for materials components.
Sometimes, once we have assigned the component to an activity we realize there is available stock in a storage location, what means we do not need to purchase the component. What should we do in this cases? We should change the procurement type?
Thanks a lot

Hi,
Standard SAP doesnot check what we require (check Plant stock before raising PR) in this case.
You can make use of the "Res/PR" indicator. Set it to "From Release", add your components & before releasing the parent activity, you can cross check for the available stock & change the material component line items accordingly.
there are also some threads available on the same topic.

Problem in determing the Component Item Category in Work Order

HI ALL,
When I enter the Component and quantity required for Work/Maintenance Order Operation and press ENTER button, its taking the item category as Non-Stock (N) item. When I checked in SPRO (PM > Maintenance and Service Orders > General data > Define default values for Component Item Categories) for Plant and Material Type combination the Item Category is mentioned as Stock (L) item.
Could you please let me know is there is any other setting from which it is taking the item category as Non-stock item instead of Stock item?
Note:
-     For this Material No BOM maintained / exist?
-     Operations are entered manually not take from TASK LIST.
-     Material type of material is HIBE : Operating Supplies

Dear,
Its not ur fault during configuration. i think in material master operating supplies under which ur material is mainted is assigned as Non stock item plz check the material master .
hope u will get ur ans

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

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

Item Category in Stock transfer requisiton.

Hi,
I have created an stock trnasfer requisition thrrough MRP.
Even though supplying plant belongs to Different compnay code, purchase req. is created with Item category U.
is there any setting which triggeres item category U in PR when created through MRP.
No special procurement key assigned in material master and procurement type is F
When i try to create STR manually, it is created with correct item category.
We have same document type for both intercompany purchase and intracompany transfer.

Hi akkshaya,
In standard system, for both intra and inter company STOs, item category is U, with NB doc types of requisitions. You are saying that no special proc key is assigned on MM so how is MRP creating these reqs? Check the creation indicator on the req to see who created the requisition.
Le me know if you would have any questions

Visibility of Non-stock component item(s) purchased with credit card

Hello.
Does anyone have any ideas how non-stock items purchased with a purchasing card can be tracked against a work order component from a planned costs and material availability point of view? We can currently get the actual costs after the fact when the credit card statement is settled. I am assuming the standard SAP approach is to use a PR/PO and perform a goods receipt to get the material availability. Are there any other options without this level of overhead (ie. PR/PO... approvals, buyers etc.)? The key would be to gain visibility that a part has been bought and is available so that the job could be scheduled.
Our current work around is to put a component with item category 'T' (Text Item) so that the scheduler knows a credit card item is required. Some locations are adding more detail to the 'T' component when the physical item is received.
Is there any way to generate different PR types based on component item category?
Any ideas are appreciated.
Thanks,
Kevin

Kevin,
You could use the user exit "COZF0002 Maintenance order: Change purchase requisition for external component" to create a different type of PR.Just change the BSART field based on item category. That should do the trick and keep the Requisition for Credit card purchases separate.
If possible, You could also explore the use of user status functionality at the operation/ level to gain visibility over the receipt of these purchases and thereby allow scheduling to happen.

Item Category "U" in Intercompany Stock Transport Order

Hi Gurus,
Your expert advise on the below functionality is needed..
Scenario:
Intercompany STO, Document Type : NB , Delivery Type : NLCC
In the Source List, Intercompany Vendor and the Supplying Plant is maintained. Also i have made the Source list relevant for MRP.
MRP is run for the material, SAP generates PR(Document Type NB) with Item Category "U" -Stock Transfer.
I am getting error message when creating PO with reference to this PR, as Standard PO document type NB does not have link to Item Category "U - Stock Transfer".
For Intercompany STO, Item Category should be blank, I am not sure why SAP generates PR with Item Category "U".
If i do not maintain the Source List and generate PR it is created with Item category as blank. Then i am able to manually assign the Source of supply.
Kindly let me, what needs to be done to generate PR for Intercompany STO in MRP without Item Category "U' in it.
Regards,
Hemant

Hi,
SAP creates the requisition with item category "U" even in case of cross-company (intercompany) purchase requisition.
When converting it to PO the item category becomes blank - as I tried and I got no error message.
Please check your settings under SPRO > MM > Purchasing > Purchase Order > Define Document Types (V_T161). You will see (if standard settings have not been changed) that NB requisition type with "U" item category is allowed for NB purchase order type with " " (empty) item category.

Implications of Item Category in BOM during MRP run

what are the different implications on the MRP run if an item is maintained as "L" for stock, "N" for non-stock, "T" for text item, etc?
how shall it affect the procurement and production process?

Dear
Stock item L
This item category is used to manage material data that allows an item to be kept in stock.If you want to enter a material that is kept in stock as a component, select this item category
Non Stock item N
This item category is used to manage material data that does not allow an item to be kept in stock.
Use this item category if you want to enter a material that is not kept in stock before use, and that is only procured for a specific planned order or production order.

Change material Item Category

Hi, maybe this topic already discuss in this Forums.
Can help me.
I have some question.
When i create Order IW31 ( Module PM ) i put material in component which this material Item Category L ( Stock Item ).
when i click button PURCHASING can not create PR error message " material is not a non stock item" and Message no. CO 382
Thanks for share

Hi,
When you put category "L" it means that it will be issued from stock, so you can't purchase it directly to the PM order. In this case you buy it to stock, and then issue it from stock.
In the case when you want to purchase directly to the order without going via stock (direct procurement), then choose item category "non stock".

Item Category 'L' (Subcontracting)

Hello,
I would just like to ask if a UB-type PO (Stock Transfer Order) could have an item category 'L' which is Subcontracting. Currently, only item category 'U' (Stock Transfer) is available in the item category field when creating a UB-type PO through transaction ME21n.
Do adding item category 'L' (Subcontracting) in the system's configuration for UB-type (Stock Transfer Order) PO makes any sense?
Please let me know your thoughts regarding this matter.
Many thanks in advance.

Hi,
item category L made for only Subcontract cycle.we can not use L in UB by following reasons.
When u use UB Doc type you can not enter SC Vendor in PO even after config L with document type UB,system shows supplying plant field.
UB can be used in Plant to plant transfer or Company code to company code transafer or Storage location to storage location transfer.
since in subcontracting cycle there is a involvement of SC vendor which has subsidiary ledger under reconciliation account and Goods issue (Components or BOM ) lying with SC vendor under special Stock, which will further consume useing movement type 543 during MIGO this functionality is not possible with UB.
Hope this will clear your doubt.

Item Category ( BOM & Subcontracting PO )

Iam Created BOM.
BOM Have the 2 Components With Item Category (L) Stock item.
Now Iam Created a subcontracting PO . But here BOM Components bydefault Item Category ( T ) Text item
what is the reason system picking wrong item category

see how the item category is defined in OS13 maybe your L item category has a flag in text item field.

Item Category N (non-stock item) in BOM creation - Preq Generation

Hi All
I have a material component that is planned in APO and not in ECC6. We would like to keep the one BOM for the finished good. Problem is that when we perform the backflush in ECC6, the system wants to backflush the material and causes errors due to missing stock.
So I assigned the material as a non stock item in the BOM but the system will auto generate a purchase requisitions for Non stock bom components (item category N) when the process order is created. It is possible to turn off the auto creation of the purchase req for non stock bom components?
I have tried the following:
- Explosion type in item data, created new key with 'Switch off planning' indicator set in system configuration
- created new 'Z' item category with inventory management de-selected
Both approaches causes system error: Puchase data of material in not maintained
I also tried leaving as a stock item with the bulk material indicator selected in the item data. This does not work as the cif will then exclude the component when data is transferred to APO
Funny enough, the system does not generate a purchase req for non stock bom items when using Repetitive Manufacturing. Any help will be greatly appreciated
kind regards
Grant brockelbank

Hello Vivek
Thank you for your response
The item is a non stock item. I do not want this item to be backflushed at all. This can be achieved using the 'N' non stock item category but the problem is that the system will attempt to generate a purchase requisition when the process order is created.
I do not want the system to generate a purchase req in ECC6 as this item is a planning material that is planned in APO (used for medium to long term planning in a simulation version). We are hoping to use the one Bom for ECC6 and APO planning. The generation of the purchase reqs is a bit of a waste as we will never convert them and there is potential to cause issues for purchasing.
Any other thoughts?
Thanks again for your help
kind regards

Change item category of BOM component

Hi,
Our user wanted to change the item category for BOM components through transaction IB12 using LSMW.Wanted to confirm whether it is possible to change item categoryof BOM component from "N" to "L" through LSMW.What exactly will be effected because of this change?And the steps to change the item category from "N" to "L" for the list of BOM component using LSMW.
Request your valuable thoughts.
Thank you in advance,
Regards,
Rubina Rahman

Hi Rubina,
N is non stock item
L is stock item
You have to make sure why the business warants to chnage the item category.
To answer the question:
It is possible to chnage the item category from "N" to "L" through LSMW (Provided depends on the number of components used in a BOM. If the number of items exceeds to multiple screen, then you have to think of developing BDC)
The effect will be: with item category "N" if the material is used in the order, based on the configuration the system shall automatically trigger the purchase requisition. With item category "L" it is assumed as stock is available and taken care by MRP program.
Suppose if it is material BOM:
          A. Use T.code: CS02 in LSMW recording
          B. Provide information like Material number, Plant, BOM usage
          C. In the item level change the item category from N to L
          D. Save the recording
          E. I hope you know the remaining LSMW process steps
Cheers,
Raj

What is use of Item Category N(non-stock item) in BOM creation

Dear Experts,
What is use of Item Category N(non-stock item) in BOM creation ?
regards
rajakarthik

Hi,
This item category is used for components which are not kept in stock if they are used in a bill of material (BOM). Non-stock items can be entered in the BOM with or without a master record. To enter a non-stock item without a master record, you must simply enter a descriptive text.
When you use this item category, the system automatically creates a purchase requisition for these components,
Special functions
The following functions are supported for non-stock items
You maintain purchasing data for non-stock items in the bill of material.
In the planning run, the system generates purchase requisitions
instead of dependent requirements for components that are procured directly. When you configure your R/3 System for MRP, you can define whether direct procurement is triggered by the planning run or by production order management.
Product costing processes take valuation data from the BOM item.
The system determines the release strategy on the basis of the price data you enter. The material group is required to produce a purchase requisition.

The stock of component item cannot be negative

I'm having this strange problem with a number of work orders. I issue all of the components. All of them. If I bring up the issue window again, it's empty. I try to release and it gives the above error. I don't get it, if there wasn't enough stock of component items then why did it let me issue them in the first place?
Thanks!

"Inventory or stock is a moving concept."
Yes, I understand that. But when I do an "Issue Components", when I hit ok on that screen, from my understanding, the components required to create the item are removed from inventory at that moment. If I dont' have enough, it tells me and won't let me complete the Issue. But it did. So at the moment I issued, all component items were in inventory and were removed.
Now I go to Report Completion, seconds later and it tells me there's not enough of something in inventory. How can that be when I just issued ALL of the components? And if I try to re-issue, there's nothing there to issue.
So maybe I have the above mis-understood. I look at the order and there's an item in there, Base Qty is 8, required Qty is 16 (2 items are being constructed) Issued quantity is 0, Available is -636. How do I re-issue these sub-components? The issue screen is blank.
Why did it let me "Issue" these components if they weren't in stock in the first place?
Thanks

Is it possible to change Item Category of BOM component

Hi,
We are in the process of implementing Guided Structure Synchronization (GSS). GSS helps in Syncing Source BOM (Engineering BOM) to Target BOM(Manufacturing BOM).
During the creation of EBOM, designer may not have complete information about the Item category, So by default it is set as "L"(Stock Item). When MBOM is created, It should have correct Item category. Using GSS, while synching operation from EBOM to MBOM, Item category is also copied and it is not allowed to change.
Is there any way to change the Item category before Sync operation in GSS.
Thanks in advance.

OmPrakash

Hi Omprakash ,
BADI used is /PLMB/GSS_FIELDCONTROL .
    Conflict is created based on Postion type. SAP recognizes this conflict and gives conflict in Reconsliation workbench.
    When user solves this conflict , BADI /PLMB/GSS_ACTION for our customer defined Action.
     In this Implementation , Target Vertex would be deleted and New Vertex is created.
    Key Mappings has to be adjusted with new Vertex.
   I have seen some side effects of this Solution. I am trying to solve them.
Thanking you,
