SNP Purchase requisitions

Hi
i have a situation where in one week the SNP planning run creates only one purchase requsition with single item for the requirement and in another it creates multiple purchase requisitions with single items...
iam unable to understand how the multiple purchase requisitions are created..can you share your ideas,
Thanks

HI,
Yes offcource we can get multiple purchase req from SNP heuristics. here is some scenarios.
1) it depends on lot size settings in product master. in your case you may be getting multiple orders of fixed lot size since demand qty is more then that of fixed qty
2) if you maintained multilple sourcing( inbound quota arrangement) you will get multilple purchase req.
Check above settings carefully..

SNP purchase requisitions inconsistency

Dear experts,
i have a question regarding purchase requisitions in the SNP planning. We have integrated purchase info records and purchase contracts from R/3 and we are using them as sources ouf supply in the SNP planning. The SNP heuristic applies purchase requisitions, but it don't delete them if the demand has disappeared.
The support told us, that the cause of this behaviour is the missing means of transport in the transportation lanes. Purchase requisitions which are generated without means of transport are inconsistent and the heuristic can't delete them.
I wondered about this statement because the lanes are generated automatically via CIF but without means of transport. Unfortunately we have to maintain them manually now for hundreds of lanes. With means of transport it works pretty fine.
Did anybody make the same experiences and what was your approach?
Kind regards,
Christian

Hi,
I thought these points might be of some help to all
1. SNP heuristic being a infinite planning create pur req even if no source is defined, with source and MOT blank, this behaviour is also observed when no MOT is defined for a lane or the MOT defined is not SNP relevant (i.e. relevant for aggrgtd planning).
2. You need to define both product specific lane and MOT lane to generate a proper Purchase req with source and MOT.
3. SNP heuristic cannot delete any transaction data that it cannot create or has not created.
I hope this helps, also you can use BAPI to define Transportation Lane (Product spec and MOT spec) which is a very convinient and useful way of creating Transportation Lane Master Data.
Thanks,

SNP purchase requisitions quantities generated with Decimals

HI Gurus,
When we run the location heuristics in SNP the purchase requisitions are (Distribution Receipts Planned ) are created without decimals.But when these are published to ECC the purchase requisitions are generated with decimals.For Example the SNP PR value is 15 and the ECC Pr is 15.200.How can i restrict this because i want the same quantity which is generated by SNP heuristics .Are there any settings in UOM(Unit of measure).I checked in the planning area for the key figure everthing is fine.
What are the settings to be made.
Dhanunjay.

The SNP might be generating 15.2 based on your lot sizing settings.
Most probably the reason you see 15( with no decimals) in SNP Planning book is because for your keyfigure, you have 0 decimals.
Go to Design mode for the plannning book, select the keyfigure and change the decimal places from 0 to 3(or any higher number)
Now you should be able to see 15.2 as stated in your example even in the plannning book
One other way to check would be in the product view(RRP3) or as someone already suggested( RRP2)
Thanks

Differentiate between SNP Deployment generated Purchase Requisition in R/3

Hi
We are implementing SNP with Deployment. Purchase Requisitions are being generated from both SNP Heuristic run and Deployment heuristic run and they are transferred to R/3. So using TC MD04 in R/3, we can see both Purchase Requistion coming from the same requirement. We want to convert the Purchase Requisition generated from Deployment to Purchase Order using ME59/ ME59N in the background. Currently, there is no difference between both PReqs in R/3, so system is incorrectly picking up both the PReqs.
It will be great help if anyone can suggest a way to differentiate them in R/3.
Thanks,
Prasun

You can identify PR by category
Category :
EA SNP: PReq SNP: Purchase requisition
EF DEP: PReq Deployment: Purchase requisition
you can use user exit APOCF013 on APO side to put some flag for SNP PR and use the same in R/3.
You need to identify one field in PR data that you can use in R/3 to identify SNP or DEP PR and by user exit you can put flag in that field .
Hope it will help you further.

Item category determination during Purchase Requisition creation from APO

Im creating a SNP Purchase Requisition in APO and when it is published to R/3, a Purchase Requisition document is created in R/3.
When this PR is created in R/3, I want the Item Category to be determined based on the Material master Special Procurement Type. ( eg: Id like the Item category to be L if the Material master Special Procurement Type = 30 (Subcontracting) ). But by standard, this field is coming as Blank and this field could only be populated during the creation from APO.
I found a user exit ( CIFPUR02 : Enhancement of Purchase Order Interface (Inbound) ) on R/3 where I tried to populate the Item Category, but when I do this, all the purchase order related data is getting deleted and hence no PRs are getting created in R/3.
Could anyone please tell me if this could be resolved using configuration and if not any tips to do this technically would be very helpful.
Thanks,
Harsha

Hi Karun,
This is the code i'm using...
select single * from marc into lit_marc
where matnr = c_eban-matnr
and    werks = c_eban-werks.
append lit_marc.
read table lit_marc with key matnr = c_eban-matnr
                             werks = c_eban-werks
                             sobsl = 30.
if sy-subrc = 0.
c_eban-pstyp = '3'.
endif.
Here sobsl = 30 is the Special procurement type
But when i try to populate c_eban-pstyp = '3', during the creation of Purchase Requisitions in R/3, in the program SAPLEMPI -> LMEPIF01
this condition is encountered which deletes all the data in the tables that is used to create Purchase requisitions.
<i>* get rsnum in the case of subcontracting
      IF XEBAN-PSTYP EQ PSTYP-LOHN AND                      "RB240999
         EXITFLAG_ORDID IS INITIAL.                         "RB240999
refresh all component tables
        CALL FUNCTION 'ME_COMPONENTS_REFRESH'
             EXCEPTIONS
                  OTHERS = 1.</i>
Could you please suggest me anything to get around this.
Thanks,

SNP Purchase Reqs transfer problem

Hi,
during the SNP Purchase requisitions immediate transfer, the pur reqs are not transferred from a specific location(although this location and products in it are active), pur reqs are transferred without any problem in other locations/products.
how to rectify this.
Vignesh

Hi Vignesh,
Check if the publication settings are maintained for external procurement for this location in APO. you can use the Tcode /sapapo/cp2.
Maintain the location no, publication type should be 21 for external procurement and ECC system accordingly.In case not maintained, kindly maintain the same. This is required for data transfer to ECC system
Let me know if it helps.

SNP Heuristic: Creation of purchase requisition

Hi experts,
we face following problem: heuristic creates purchase orders when there is no source of supply.
Background:
there is a forecast demand for a location product on a customer location without transport lane to the production plant due to false master data.
The SNP heuristic generates purchase requisitions to fulfill the demand and there is no requirements shortage.
So it is hard to recognize which forecast demands can't be fulfilled.
Is there a parameter in material master or in a heuristic profie which disables the creation of purchase requisitions in snp heuristic when there is no source of supply.
If no purchase requisition is created there will be a requirement shortage which can be recognised by an alert.
Thanks for your help.
Robert

hi.
As per heuristic process , the system will create a purchase requisition if there are no Tlane exists and the material's procurement type is F/X since it is a infinite planning.
Now you can use a optimizer or CTM to restrict the system from creating purchase requisition.
Also you can try with location heuristic.
Hope this can help.

kaushik

Purchase requisition date in SNP planning book and product view not in sync

Hello Experts,
We have an issue with display of purchase requisition date in SNP planning book.
We are manually entering the PR's for a perticular week from Monday - Sunday(01.09.2014- 07.09.2014), when the last PR is entered on 07.09.2014, it does not appear on the same day in planning book(cell becomes empty) and moves to 06.09.2014, thus quantity on 06.09.2014 is the summation of the quantities present on 06th and 07th.
The PR dates are appearing correct when we click on display details in planning book and they are correct in product view, MD04 as well.
Additionally, this is the same date on which daylight saving time comes into effect.
Kindly advise if anyone has faced similar situation earlier.
Many thanks,
Aditi

Hi Aditi,
Check the time zone that you have in your location in ECC and APO.
Also note it is recommended that you maintain the same system time zone in APO and in ECC. (check tcode STZAC in both systems).
Different time zones should generate this kind of inconsistencies.

SNP Heuristic recreation and adding of Purchase requisition

Dear All
Thanking In advance,
Critical Issue
We have scheduled a heuristic run for 7 FERT materials,
Run was successful in simulation version, When we take a re-run
(heuristic) on the same data,It is adding the quantities of the
forecast to the same purchase requisition for only two FERTS, for
others it is deleting and recreating purchase requisition same as the
forecast requirement. This in turn is leading to doubling of
requirement for these two FERTS at the lower BOM materials.
e.g.If demand is 10 and we run heuristic in first run it will create 10
purchase requisitions, if we Re-run heuristic on the same data it is
adding 10 more quantity for same purchase requisition.
Before generating the requisitios it will show the message Invalid order and help of which shows "Order does not exist in Live-Cache"
What could be the reason for this?

SNP Heuristics generates purchase requisition

Hi Experts,
I have a requriement to generates purchase requisitions start date at Monday; Im trying to use period factor but still I gets the reqs still falls in different days and also the planning calendar under the lot-size. Is there any other ways that I can apply this requirement?
My lot-size is weekly bucket and 1 day transportation duration and 1 day GR.
Thanks
Regards,
Lhon

Thanks again for your reply; yes some of the days that didnt fall has holidays for that current week thats why it didnt schedule at the desired date but some of the Preqs generated were fall on other days even without any holidays in the calendar. Except for the calendars of the transport and handling what are the other factors thatc an affect this specified period factor settings? Other than this setting would you consider any other scenario to apply this requirement?

Purchase Requisition Is Being Getting Created In APO But not being publishe

On doing, SNP Location Heuristics on one of our item, purchase requisition is being getting created in APO (We are able to see the same in RRP3) but the same is not being getting published in ECC. On doing CCR of the said location - product combination, it is showing Error u201C182u201D. We have checked the following parameters :-
Item is an APO Item i.e. X0.
It is having a proper Purchasing Group.
As This be a purchase item. So, it is having a valid single Purchase Info Record.
Item Has Not Been Blocked At Any Level.
Vendor From Whom This Item is being getting procured is also open (Not Blocked).
Please suggest what else to be checked and what else can be the reason for non-flowing of purchase requisition from APO to ECC.
Thanks & Best Regards,
Sanjeev Chugh

Hi Sanjeev,
Please check change pointers if any and send them to ECC. Check the order in the planning book whether it has picked the same source for which there is a Purchase info record. If these all are fine then You send them to ECC from the CCR then check the log in ECC through CFG1 tcode.

Purchase Requisition Transfers from SCM 5.0 APO to R/3

I am working on SCM 5.0 -- transferring Purchase Requisitions from APO to R/3 from SNP heurristic run. I am wondering if there is any documented procedure of available options and the steps involved in setting up.
Can you transfer only certain Purchase Requisitions instead of ALL?
Can you setup approval workflow to allow the transfer of only approved PRs ?
What steps involved to get PRs from the SNP Heuristic?
I found the IMG Activity (SAP SCM Implementation Guide  Advanced Planning and Optimization  Supply Chain Planning  Supply Network Planning (SNP)  Basic Settings  Configure Transfer to OLTP system).
I shall greatly apprecaite if some one answers the questions and points me to some 'How to Guide or the steps involved in setting up'.
Thanks

Devendra,
You actually need the SCM-APO-CIF (Core Interface) Training for this. A Pre-requisite to that is the APO Overview. Have you undergone it ?
In Short i will tell you the answers you want ... I hope you will reward me with Points if you feel it was helpful.
To Transfer PRs from APO to R3 following setup is needed ..
- Do Configuration of STO (Stock Transfer) in R3. Ensure Stock Transfer PRs and STOs between the 2 Plants can be created Manually in R3. This will require you to do a Lot of MM & SD Configuration on IntraCompany STOs.
A Key Part for APO is to set the STO Order Types for the
Source and Destination Plant, Assign Vendor to the Shipping Plant, Customer to the Destination Plant .. etc. A Test of correct setup is your ability to create a PR and STO manually in R3 first before you do APO.
- Setup of all APO Locations (Plants in SAP-R3), Products (Materials in SAP-R3). These are done via the Location and Product Integration Models. Make sure you have defined the Timezone in the Plant and set the Plant in SAP as DC or Production Plant (Refer CIF Training).
- Setup of Transport Lanes in APO (done manually in APO).
You define Transport Durations here.
- You have to have the Purchase Requisition Integration Model Active for those Product Locations. To do the Integration Model all CIF Configuration including the one IMG you have described in your Question is to be done. Assuming that the Products are set to 'X0' MRP Type in R3 ... so they are set to Planning in APO.
- For Setup in "Configure Transfer to OLTP" it is best to select 'Periodic Transfer' so you can actually control the Product-Locations and Date Range of PRs APO has created. The Planning Runs create 'Change Pointers' to send the PRs to R3.
- Define in APO that you will be sending Purchase Requisitions at your Destination Location to R3. You use 'Publish Change Pointers' - /sapapo/cp1 to do this.
- The Change Pointers are created after APO Planning run which can be sent to R3 using /sapapo/c5. You should send them periodically after you're satisfied with the planning results or in Night Batch runs after your Planning run.
- To Control some type of PRs you will have to use User Exits in APO for CIF that send External Procurement / PRs from APO to R3. This is not Standard. But I am not sure why you will have different types of PRs for Stock Transfer between 2 Plants. There is no need. You can control PRs between 2 Locations to not go to R3, via the selection of locations in /sapapo/c5.
Hope you find this usefull.

Purchase Requisitions from APO to R3

Hi,
when iam transferring purchase requisitions from APO to R3, other snp orders are also automatically tranferring to R3 . How to prevent this?
Thanks,
Dhanush

Go to the following menu path
SPRO> APO>Supply chain planning> SNP> Cnfigure transfer to OLTP systems
Based on your requirement: only transfer SNP generated Purch Reqs and dono transfer SNP generated planned orders to ECC, you have 2 options
Option 1--Immediately transfer SNP generated Purch Reqs and never transfer any SNP planned orders
Config required: (1)SNP( Select Radio Button- Immediate Transfer) (2) Check the " NO SNP PLANNED ORDERS" (3) Check whether the Dist Definition for the plant is maintained for External Procurement
(4) Check the CIF queues and clear or reset the status
Preferred Option2 for future projects in mind--- As this is a global setting, it is better to have periodic transfer set and then use C5 transaction to send the Purch Reqs to R3 using the Filter as Order Type.
This way you are not putting a hard stop for sending the planned orders to ECC as in OPTION 1.
Config Required: (1) SNP( select Radio Button- Periodic Transfer) (2) Run C5 transaction and give in your plant/product selection and APO order type=21(ext Procurement)
Thanks

Aggregation of Purchase requisition in Optimizer

Happy Diwali to all,
Can we club the purchase requisitions generated from SNP optimizer to one requisition for month, as SNP optimizer will plan for optimize the solution by generating requisitions with qty 2,3, or 7 and 8 qty, Now i want to club all the requisitions to one requisition to total quantity 20 Nos.
Can any body address me how can i tackle the situation, as i want the clubbed requisitions to book the vendors capacity for 6 months or year with higher quantity.
Regards,
Amol Chavan

Dear Ian,
We have tried by creaating planning book of monthly bucket but results are not satisfactory, Is it possible to club the requisitions by PPDS heuristic in lot size procedure by periods.

Heuristic run @ destination location is creating the purchase requisition without source plant

Hello All,
Trust you are doing well.
Believe this is the good time to connect with you all get some advice on the below mentioned scenario:
Material (XXXXXX) is discontinued at source location (Plant specific material status: 90) but the same material
(XXXXXX) is still used in destination location (plant specific material status: 60). Here heuristic run @ destination location is creating the purchase requisition without source plant.
Here the customer expectation is that “SNP should not create the order, since the material is discontinued in source plant”
Could you please advise?
Regards,
Prabin

Hi Prabin,
You can change the SNP profile to NO PLANNING automatically and exclude the target location from the SNP run. Maybe you can try using Badi: SMOD_APOCF005.
This is what I would do:
1- Do not exclude the status 90 in the iModel.
2- Then when you change the status in order to discontinue a material at the source location you will be changing the status from 60 to 90 and you will CIF this modification to APO. At this time, I would use the BAdI: SMOD_APOCF005 to identify this situation. You will need to add a code in order to identify what are the possible target plants of your source plant and you will need to change the SNP Profile at the target location.. look for a BAPI for this...
Take a look of this document to see an example code of SMOD_APOCF005:
