Difference Between PO Account Assignment P and Non Stock Item (N)

[Former Member]

Dear All,

Could any able explain difference between PO Account Assignment Category P and Non-Stock Item (N) as

- P-: Project Stock, results in a consumption posting. Stock is taken in to the books & transferred of to the Consumption accounting.

- N : In case of Item Category (N), stock also take into books and directly issue to Project/NWA.

As per my understanding in both above case material will be issued directly to project at time of GR in MIGO.

Than When we need to use P and When to use N ?

regards,

Hi Atul,

Please note there is a major difference between Item Category ( L or N etc) and Account assignment Category ( P or Q or N or K etc).

the first Item Category is specific to the characteristic of material i.e. whether it is a stock material (L) or non stock (N) or service (D)  etc.

Whereas the account assignment defines which controlling object should be hit while procuring material and what corresponding entries should be expected in FICO, once goods are received from the resulting PR/PO.

Now to answer your question when we raise a PO with account assignment as P the Project cost is not hit, it hits the consumption account, and it is available as Project Stock. once goods are issued against this project stock actual cost is accumulated against the project.

In case of non-stock item there is no stock take, Once you do the GR it is considered consumed.

Hope it clears your doubts..

Regards

Hi,

it is requirement of the business,

if you are carrying out the purchase requisition for material from project system for non stock item for a projects ,and the material is procured for an activity ,by default system shall pick up account assignment as N

when you procure /raise the PR/PO for  material from material management,it generally is preferred to takethe account assignment as Project P

it entirely depends upon the business requirement,wether they want to procure the material from projects directy or externally with account assignment as project.

for further you should read help.sap.com and also check with your MM consultant

Hi,

Material Consumption is depend on movement type (as 261 like that, that is good issue not Goods receive) not account assignment as P Q N.... & more.

account assignment as above will show only object as P for project Q for project MTO, and N for network so once you completed GRN it will take movement type 101 that is not consumption movement and stock will display in MMBE transaction with that object.

Hi Rajat,

Account Assignment Category P is used in Purchase Order (ME21N), where you can directly purchase the goods against Account Assignment to WBS element / Network Activities. MIGO posting and cost is calculated for project only.

Non-Stock is nothing but for the material procured outside inventory. As per Industry standard they will maintain all material as Stock Items, but still there might be material with high price or required once in a year or so, they will not maintain as inventory. For these materials we need to procure through a vendor when ever it is needed. In Project system (CJ20N), we have an option, where you can trigger automatic PR (reduce the work load), and PO is converted by stores. These materials have lead time to deliver maintained in material master, which makes the work of project controller easy for planning. Here you need to use network activities only.

When companies are full into Project System, they will not allow users to directly procure the materials via ME21N (Purchase Order), to get all the logs and to have a steady process.

Both have similar usage, but the purpose of it might be different.

Thanks
