Unit in purchase requisition

Hi all,
When I create a purchase requisition, the unit taken is unit of measure. I can not modify it, and use the order unit.
When I do the purchase order based on this PR, the unit is the order unit. The order unit is well define in MM03 (display material) and ME13 (info record).
I want to use the order unit in the PR. Is it possible and how ?
Thanks for your help
Regards.
Mathieu

Hi
PR is an Internal Document....Ie) The users or User Department in your company are requisting the Purchase Department to arrange or Procure material or service for their purpose....that they will ask in UOM only.....they wont bother about or many cases not aware of the Order unit...
So as per SAP Best Practice, the PR will have only UOM...not Order unit...
reward if useful

Import Purchase Requisitions from one Operating Unit to a different Operati

The need is to import Purchase Requisitions from one Operating Unit to a different Operating Unit.
There are 2 operating unit with one inventory orgs in each. But the 1st is OU( It is a club) merely creates Purchase Requisition, and its not a advisable process to have a separate Purchasing process in that OU as it is too small ( but for financial reasons it has to be defined as a separate OU). So we want the Purchase Requisitions created in the 1st OU to be imported in the 2nd OU. Is there any way we can achieve this. Note: Since Order Management is not implemented we cant use the Internal customer setup and we wont like the PO to be created in the 1st OU as we do in standard Intercompany invoicing process.
Any solutions/Pointers/workaround for this.
Regards,
Manoj

As long as you have the same master org in the 2 operating units, all you have to do is
INSERT INTO mtl_system_items_interface
            (organization_code, segment1, transaction_type, set_process_id, process_flag)
   (SELECT '&new_Org', msi.segment1, 'CREATE', 100, 1
      FROM mtl_system_items_b msi
     WHERE organization_id = &old)And run the Import Items request.
Hope this helps,

Unit of measure in a purchase requisition

I want to create a purchase order using a material with two unit of measure, base unit of measure and Order unit.
I want use the Order unit in the purchase requisition but the system deletes this unit of mesure and sets the Base unit of measure.
Anybody knows what can I try to use the Order unit of material in a purchase requisition?
Thank you,

Hi Ana,
The Purchase Requisition always uses the 'Base Unit of Measure' maintained for a material in the Item Overview section.
If you want to use an alternative 'Unit of Measure' you can specify this in the 'Source of Supply' tab in Item detail. This will be the 'Unit of Measure' that is adopted into the PO when the PReq is converted. You have to also make sure that you maintain conversion factors between your UOM's.
Hope this helps,
Ravelle

Unit of measure on Purchase requisition

Hello!
When I create a purchase requisiton with material master, the unit of measure comes closed, and I can't change it.
I tried to put in the material master more than one unit of measure, but the field on purchase requisiton still closed.
I tried to take off the obrigatory of the field "unit of measure" on the purchase requisition, and it doesn't work...
Somebody knows what can I do??
If are there some alternative?
Thanks!

Hi Camilla,

Error in creation of purchase requisition

Hello Sap Guru,
When we are trying to create a purchase requisition under t.code ME51N, we are getting error message "enter valuation price"?
If anyone can please explain the reason & solution of this error.
Thanks In advance
Deepak Garg

{code)When we are trying to create a purchase requisition under t.code ME51N, we are getting error message "enter valuation price"?{code)
Hi,
it is sap standard process when you create PR and if material master record exist the price is automatically taken from the valuation price field. if record not exist enter lum sum price of requested material price.
When purchase guy create po with reference to Pr they can change valuation price also.
In custommization for Purchasing under Purchase Requisition -> Define Screen Layout at Document Level, you can set price and price unit. The Valuation price field can be set as a mandatory or optional input field.

PM (T-code IW32) - Creation of purchase requisition permitted price=0$

Hi,
In IW32, we are able to enter a price of 0,00$ and save the purchase requisition. In ME51N, this action is not possible, we have to enter a price > 0,00$. Why are we able to save a 0,00$ purchase requisition using IW32, and not ME51N? We should not be able to create a 0,00$ purchase requisition in IW32 !
IW32 procedure of PO creation:
1. Run IW32
2. Enter order number
3. Go to «components» table
4. DO NOT enter component, enter description, reqmnt qty, UM, IC, Plnt, OpAc
5. Select the line item
6. Click on the Purchasing button at the bottom left of the screen
7. Enter Price = 0,00$, G/L account number, and save
8. Quit IW32 transaction
9. Go back in IW32, select the line item, click on the purchasing button, and there will now be a purchasing requisition number in the Purchasing Data table.
10. Go in ME54N. You will now be able to release a 0,00$ purchase requisition....
The system SHOULD NOT allow me to create and release a 0,00$ purchase requisition. How can I fix this?
Thanks,
Julien

Hi,
Go to SPRO > MM > Purchasing > Purchase Requisition > Define Screen Layout at Document Level > Here for Field selection key "ESTF" i.e. Requisition from prodn. order, mark field "Price and price unit" as required under selection group 'Quantity and price'.
It will start asking Valuation Price during Order Creation for PR.

Create purchasing requisition or purchase order from service order

Hello experts,
we are facing the following problem:
We are implementing Customer Service module and out of the notification we create a service order. In the service order (components tab) the technician declares the spare parts he has to order from the vendor. We do not keep stock of the spare parts so all of them have to be ordered from the vendors.
We have managed so far to create a reservation for the stock material and a purchase requisition for the non-stock materials of the service order according to the standard sap documentation. What we need is to create a purchase requisition or a purchase order for the stock items using standard logic.
Thanks
George

Automatic convert of planned order to purchase requisition with latest info price

Dear Friends,
Our client want to convert planned order to purchase requisition through background job,but they want to pur requisition picking price should be latest info record price.
how can i map in to sap,is that possible in T.CODE MDUM, pl help on this requirement.
Thanks &regards,
Sabhapathy R

Hi Sabhapathy R,
The price in the Purchase Requisition is the Valuation Price of the material master.
If you press F1 in the Purchase Requisition on the field Valuation Price at tab Valuation , you will see the SAP documentation:
Price in Purchase Requisition
Shows the price of the requested material per price unit.
Use
The price and quantity set out in the purchase
requisition determine the value of the purchase requisition item or
purchase requisition. In turn, this value is applied in determining the release
strategy for the requisition.
In Customizing for Purchasing under Purchase Requisition ->
Define Screen Layout at Document Level, you can set price and price unit.
The Valuation price field can be set as a mandatory or optional input
field.
Procedure
Input mandatory:
If a material master record exists for the
requested material, the price is automatically taken from the valuation
price field.
This is explained in several threadhs:
Info record price not comming in PR after "Assign source of Supply" in PR
The price of the Info Record will be determined when the Purchase Order is created.
If you want price to picks from your Info Record when the PR is created, then check for a user exit or BAdI.
Thanks and Regards,
Mariano

Purchase Requisition Release Procedure Modification

Hi
In Purchase Requisition Release, we have two deviations in business requirement from standard SAP behaviour:
1. In multistep release, system allows PR release to be revoked by a lower level release authorized person even though higher level release has been done. Example, PR Release has release codes A1, A2 and A3, A2 can revoke release even after A3 has released the same. How do I prevent this from happening?
2. If business requirement is to have release procedure based on item cost per unit and not on total value of the line item, how can this be achieved?
Appreciate any guidance on these issues
Thanks
Sriram

Hi,
There is BADI ME_REQ_POSTED
in method POSTED you can write your code to trigger the workflow and get the information related to release strategy and
Purchase requisation .
for more than one PR use below logic .
LOOP at im_eban into gwa_im_eban .
 concatenate gwa_im_eban-banfn gwa_im_eban-bnfpo into gwa_objkey .
add data into container -----------------
 gwa_event_container-element = 'PurchaseRequisition'.
 gwa_event_container-value = gwa_im_eban-banfn.
 append gwa_event_container to gi_event_container.
 clear: gwa_event_container.
 gwa_event_container-element = 'ItemOfRequisition'.
 gwa_event_container-value = gwa_im_eban-bnfpo.
 append gwa_event_container to gi_event_container.
get the other details and create event to start workflow .
select single * from eban into lwa_eban where banfn = gwa_im_eban-banfn
 and bnfpo = gwa_im_eban-bnfpo .
 if sy-subrc <> 0 .
 call function 'SWE_EVENT_CREATE'
 exporting
 objtype = 'BUS2009'
 objkey = gwa_objkey
 event = 'zcreated'
 tables
 event_container = gi_event_container
 exceptions

ENDLOOP .
Hope this will resolve your issue.

Tolerence Limit for Purchase requisition and purchase order while saving PO

Hi,
i need to create an Custumer Exit for PO application program.
the requirement is given below.
Purchase Orders are created with reference to a Purhase Requisition. This is exempted for PO Document type ( ZLON ).
Material value in the Purchase Requisition (PR) should be checked while creating the PO and it should not be allowed more that 110% of the PR value.
There are instances PR may get split into several Purchase Order (PO)s. It should be checked for the single unit for every PO.
In the case of different requirement dates, there may be differeent line items for the same material in the same PO.
let me know which exit is used for this requirement
morever i have seen exit " MEQUERY1 ".
but iam not sure whether this will work or not.
Thanks.
Sunil

After this follow the normal step.
for pur req use object 0080.

CRM service order does not create purchase requisition

Dear experts,
CRM 5.0
We have a scenario where saving a released service order should create a purchase requisition in ECC and update the document flow. I have performed the following steps and still the PR isn't getting created.
1. Configuration in CRM and ECC for integration of service processes with logistics and maintaining the purchasing document types.
2. Maintaining standard pruchase groups in ECC table V_TMW01
3. Assigning standard purchase org to the plant
4. Making sure correct RFC destination is assigned to the logical system.
Am I by any chance missing some middleware steps as saving the service order does not even trigger anything in the system?
Thanks
Ritwik

Hi Ritwik,
Just check the following activities are maintained or not
1) You have created the subscription in SMOEAC with Site , Replication object and Service Order
     Process type in the criteria value.
2) You have maintained the customizing entry in CRM in spro for the following combination in logiistics
    Integration for Trans.Type Item Cat. Service Organization Org Unit (Service) Log. Scen.

 - attribute BSA as backend PR type (NB)
 - this group is responsible for Entry channel procurement (setting in Function tab)
4. Under Loc Purchasing Group we assigned RFC user which is same defined as RFC user in both EBP and ECC client.
 - attribute DP_PROC_TY defined as backend ECC PO type (NB)
5. Attribute CUR define for entry Channel.
6. Remote connection established with the same user defined under Organization Unit
