Purchase Requisitions in MRP

Dear All,
when we run MRP and convert some plan orders into P/Requisitions.PRs are not firm.some of PRs have not been converted to Prders.
so when we run MRP again it did't take PRs into schedule receipts.so it generates plan orders even its PRs are already there.so how can a planner guess which PR is to be processed.
and double PRs generated.so how can i avoid that

Hi Ahmad,
If you want to firm planned orders, then use MRP type P1,P2,P3,P4 and P5. The firming logic of already existing and new planned orders are differs for the MRP type P1 to P5. You can select as per your requirement.
Then if you want the system do not generarate new Planned order if PR exist already, please select the Individual/Collective indicator in MRP 4 view to Collective requirement (02).
Thanks and regards

Creation of Purchase Requisition with MRP - MD02

Hello,
I have created a sales order using one material with MRP. When I run MRP-transaction MD02 for this material, a purchase requisition is created.
What we want is to block the creation of the purchase requisition when the sales order has delivery block (code 02). I have been trying to use this enhancements; setting break-points in all function modules, but when running MD02 is does not stop there:
MEREQ001      Customers' Own Data in Purchase Requisi
LMDR2001      User exits restr. profiles of opt. pur.ord.-based load bldg
LMDZU001      User exits in additional planning
M61X0001      User exits PP-MRP materials planning
M61X0002      User Exits PP-MRP Material Requirements Planning Evaluation
Do you know a way to do this or also change data in the purchase requisition created with MD02?
Thanks and regards.

Dear ,
Are you very particualr to process the Sales Order demand when there is a delivery block ?
To restrict that one you can do the following steps :
1.Goto Sales Order -VA02-Select the line item -Double Click -Select the Schedule line tab -Set Sechedule line item categoery as CN instead of CP.If it is CP then it will processed through MRP
2.Change the pricining date and make credit block for sales Order and do not release though VKM3 so it will not be tearted through MRP run to have PR geneartion
Hope this is clear

Purchase requisition through MRP

Dear All,
When we create requisitions from MRP, it shows the requisition is created by the description of the MRP controller and not the user ID, as would normally be expected in manually created requisitions (Tab-Item Level-Contact Person). The question is u2013 for MRP created reqs, is there a way to influence this and have those reqs show the user ID as well, just as the normal manually created requisitions? Right now description of MRP controller is displayed for Purchase requision created through MRP
Your reply would be appreciated!!!!
Thanks!!!!!
Warm Regards!
Sneha

Hi Sneha,
As such when we trigger the MRP the purchase requsition created will showing as status created by as per the MRP controller that you mentioned in MMR..
But i don't thing that such config is there were we can get the user specific status while triggering MRP .

BADI/User exit for Purchase Requisition from MRP

I am looking for a BADI or any enhancement when a purchase requisition is created or modified from MRP .ie. MD50 transaction. Can anyone help ?
THanks in advance.

Hello Shareen
Have you had a look at package <b>MD03 </b>(contains transaction MD50). It contains lots of BAdIs. Perhaps the following ones may be useful:
MD_PLDORD_CHANGE (BAdI for Changing Planned Orders)
MD_PURREQ_CHANGE (BADI for changing purchase requisitions)
However, I should mention that I have not found anything when I checked the <i>Where-Used-List</i> for these BAdIs (on ECC 5.0).

Stock Transfer Reservation in spite of Purchase Requisition in MRP run

Dear SAP gurus,
We are running MRP heuristic on the PP/DS and we have different results comparing our development and productive environments.
In our productive environment purchase requisitions are generated and in our development environment stock transfer reservations are generated as result of the MRP run.
Where can I check differences of configuration that would be causing this?
Thanks and BR
Mauricio

Mauricio,
I guess I was not clear in my suggestion, I apologize. Differences in T001W between ERP dev and prod will not necessarily generate your problem, differences in sourcing within APO between APO dev and APO prod will generate the differences. I only mentioned the vendor number because a transportation lane can exist 'source plant > destination plant', but also you can have a transportation lane 'vendor of source plant > destination plant' which would also have an impact on the type of req created.
Easier to check the sourcing, //PWBSRC1, mentioned earlier. Your dev system should contain no objects that relate to Stock Transport orders. You can delete the STO sourcing records within that transaction, which will also delete the material assignment to the Transportation lane. Hopefully you will then get the default external supply proposal, which is normally a Purchase req.
Also check for presence of quota arrangements //SCC_TQ1. Delete any that unnecessarily refer to an STO object.
Best Regards,

Purchase requisitions in MRP run

Hi ,
When MRP is run for the total plant , MD01,what should be the control parameter for create pur req ?.
I checked by altering the control parameters for MRP run(MD01). When MRP is run with option 1 (in create pur. req) it creates pur requistion and when run with option 3, it creates planned order.
In the plant there are raw material as well as semi finished products. So when MRP is run for the total plant what control parameter should be used ?
Regards
ShankarR

Hi Shankar,
Once you define which type of procesing you need for Raw Materials and Semifinished products you can control the creation indicator per material with MRP GROUP in MRP 1 View (MARC-DISGR).
You define this parameter per plant and you can assign it to different materials. Tx: OPPZ
IE
MRP Group
0000 Creates Purchase Requisition
0001 Creates Planned Order
There are other parameters that you can control with MRP Group
So for Raw Materials you can use 0000 and for semifinished product 0001. (Let you Key user know what he prefers, its going to depend on the business!!!)
Kind regards,
Federico

Planned order to purchase requisition - Manual / MRP---How do we confirm

Hi,
I have a planned order which is converted into purchase requisition (PR). I want to know the following.
I know only PR number now.
a) How do I know the reference planned order from Purchase requisition number? (In PR, creation indicator shows as U-Converted planned order)
b) How do I confirm whether this planned order is created manually or by MRP?
Please help me in finding out the above.
Thanks in advance
Muthu

Hi,
a) When you convert the PldOrd into PurReq it disappears from table PLAF, it ceases to exist. There will be no PldOrd-reference in PurReq (you will not find such field in EBAN). (if you check field RSNUM in PLAF before converting the PldOrd and you check field RSNUM in EBAN after converting the PldOrd into PurReq, you wlll find the same number)
b) It's not easy to say. You can check PLAF-PSTMP and PLAF-PUSER and compare these with data you get from trx STAD. But this is also not an exact methode since these field are in connection with the last date of change.
Firming indicator cannot help also since you can remove it manually... - even though the PldOrd was changed manually, no firming indicator will be seen...
(Of course, generally firming indicator helps if the user doesn't remove it intenionally)

Purchase Requisition and MRP

Hi All,
When we Run MRP, system will create the requirement.
As in case of Production Order , FIRM indicator is there for order confirmation.
But for purchase requisition there is no such confirmation tab i observed.
Is there any facility there any such tab/tick available in PR which FIRM the requirement.
As my requirement is when i run MRP say today for certain SO item system give me the requirement of say 100 XYZ material code item. And creates the PR 450000010.My purchase department starts working ON THIS PR.
But next time when i run MRP, system again generate the PR 450000011 of 150( 100 from old and 50 new ) for same items XYZ..
But i observed that in this case previous PR 450000010 is deleted and new qty is updated in lates PR.
User dont want this , system should create new PR every time when i run MRP without deleting old one
Best Regards,
SAPMM

Hi,
The effect of it is that MRP won't be able to change the PR anymore.
SAP help (F1)
Firms the purchase requisition or delivery schedule line of a scheduling agreement, and determines that it cannot be automatically changed by the materials planning and control system.

How to attach Source of Supply to Purchase requisition(by MRP)

Hi Friends,
Source list - we are maintaining Source list for source of supply.
Please tell me how to attach Source of supply by means of source determination to the Purchase requisition(generated by MRP) ?. What are the configuration and transaction steps?.
Thanks

Define fixed indicator in the source of supply , and set the source list usage of MRP to "1 "
Below is help from sap:
==================================================================
Determining the Source of Supply via the Source List
The system first checks whether a quota arrangement has been maintained for the material, which has a validity period that covers the requirements date of the purchase requisition.
It then checks whether only one entry exists in the source list that is relevant to MRP. The indicator for source list usage must therefore be set for a particular vendor so that purchase requisitions and delivery schedules, which are created during the planning run, are automatically assigned to this vendor. In the case of a delivery schedule, you must also have maintained a scheduling agreement for this entry.
If you have maintained all the entries correctly, the system creates a purchase requisition with the source of supply that is recorded in the source list.

Purchase requisition after MRP for Semifinished & raw material

Hello Gurus,
Please guide me in following scenario :
FERT - X ---> HALB (subcontracting) - Y ---> ROH - Z
Requirement : X - 1000 , Y - 1000 & Z - 1000
In this case, when I will take the MRP for X ,then MRP will generate PR for Y & Z.
But in my case, client purchase the Z & sell it to vendor & then vendor will sell the Y to my client. He wants the requirement of Y & Z both after MRP run of X .
FERT - X ---> HALB (Purchase) - Y ---> ROH - Z
What can I do to map this in SAP?
Thanks & Regards,
Sagar

Hi Sagar,
It can also be maped in following way. Please take your MM and FI Consultant with you.
It could be map in following way:
Create BoM for Z (FG) and add Y (SFG) & X (RM). Keep the procurement type for both as F. Use special procurement key as 30 for Y (SFG). Mark NOT RELEVANT TO COSTING indicator for X in BoM. Maintain MRP type = ND for X (RM).
Now when you run MRP system will only create Dependant requirement for X (RM) and it will check stock of Y (SFG) as well. If stock of Y (SFG) is not available, Subcontracting PR will be generated for Y (SFG).
MRP will not be accurate for X (RM) since it has got dependancy on Y (SFG) which is going to be subcontracted from some Vendor. You can look for Re-order point planning or you can adopt the way suggested by Satish or you can make a new Infostructure in MM which will be updated for consumption movements for X (RM) which later can be used to make its PR directly to Vendor.

Shoyeb

Creating purchase requisitions instead of planned orders after MRP run in MDBT

When running regenerative planning in MDBT for plant with following details ,The system has to provides planned orders for the materials .
Processing key:NEUPL
Create Purchase requisition :3
Schedule lines:3
Create MRP list:1
Planning Mode:1
Scheduling :1
But sometimes it provides purchase requisitions for certain materials.The problem happens for different materials at different times.
I checked the material master and found that procurement type is external procurement.Business need to create planned order for the materials and then want to convert it to purchase requisition.
MRP group is assigned to the materials but no creation indicator maintained for the MRP group.
Please tell me why this run creates purchase requisitions suddenly and in the next run it disappears?

Hello
Maybe someonelse is running MRP in another transaction, such as MD02, with a different parameter. Check on transaction MD05 when was the last MRP execution and the user that ran it.
Also check if there is any active implementation of BAdI MD_MRP_PARAMETERS.
If you don't have a cretion indicator, maybe it would be useful to set it for your MRP group, with the parameter 3, in order to make sure that planned orders will be created.

MRP no purchase requisition generated

Dear Experts,
I have a problem that I can't generate purchase requisition after MRP run.
Example : I have a finished goods material FG and under which has 1 component Mat 1.
The setting in material master of Mat FG is internal procure(E), MRP type = "PD".
Mat 1 is external procure(F) and MRP type = "ND"
I entered the forecast requirement in MD64 for Mat FG and I set the Create PR indicator to 1 in MD02
and start running MRP.
Planned order created for Mat FG, but no PR created for Mat 1 which only shows dependent requirement for Mat FG in MD04.
I can't see there is Mat 1 in the planning file(MD21) under Mat FG.
Any settings I missed and can anyone help?
Thanks a lot.
Claude

Hi,
IF you do not maintain mrp type PD then system wont consider the material during MRP run, so convert it to PD.
Also go through the below link which will clear your doubts of master data maintenance for MRP.

Automatic creation of purchase requisition for semi-finished product HALB

Hi Gurus,
We want the MRP to generate automatically a purchase requisition, instead of a planned order, for a semi-finished product. Of course, we still want to be able to convert it to a planned order.
thanks
Jean-Francois Millaire

Hi Jean-Francois Millaire,
You want a purchase requisition after MRP run & you should also able to convert that purchase requisition to planned order,If i understood correctly, hope this is your requirement
First one is possible -in MD01/MD02 maintain create purchase requisition as "1"
Second is not possible,its not possibel to conver a PR(purchase requisition to Planned order where as vice versa is possible
confirm my understanding,pls revert if you differ
