Net requirement in MRP

Hi
I have following scenario
In production order of material A there is one bought out material B with quantity 10 KG.
Quantity of material B require can be +/- 5 % in any production order
Overdelivery of 5 % allowed from vendor.
After MRP, PR is created for 10 quantity which is then converted to PO.
If only 9.5 kg is require for certain production order then after receiving 9.5 kg we short close Purchase order of 10 KG.
But when MRP is carried out then it will create PR for 0.5 KG. Which is ok as per standard SAP.
Solution -- Reduce quantity in production order for material B to 9.5 Kg.
Is there is any possibilty or any setting by which we can tell MRP to -5% receipt is allowed for requirement of material B and it should not create new PR.

Hi,
Mark the 'Final issue' indicator in the component overview in the order against the said item.
Also while issuing the component either with MIGO or MB1A mark this indicator.
Hope this helps you.

Net requirement calculation in MRP

Hi Gurus,
Is there any way we can exclude Created Purchase order ( Not yet released ) in MRP run for the Net req calcualtion . ( pl suggest other than exit )
Regards,
Prasanna

Hi prasana
Net requirement calculation in MPR will include firmed receipts. ( P.O.). You can only block what are all given in plant parameter.
We can exclude in Availability Check, in scope of Availability check setting.

MRP Net Requirements Calculation

Hi Guys:
I defined a Planning Horizon of 40 days, for Example if today is the start date Since Planning horizon is 40 days (01/30/2012).
Vendor Lead time = 2months
Purchase order to vendor with Delivery Date (12/20/2011) : 5000 Pc
Purchase order to vendor with Delivery date ( 03/04/2012): 6000Pc
Onhand Inventory = Zero
So i have Sales order for 10000 with Delivery Date ( 12/28/12) with in the Planning horizon.So when I run MRP using MD02 ,
Does the system consider Purchase orders with delivery dates that are outside planning horizon into the net requirements calculation?
thanks for the help.
Kodali

dear friend,
as far as i know the available stock is calculated as follows:
plant stock
safety stock
+
receipts (pur.orders, prod. ordersfirmed proc. proposals)
requirements quantity (say, PIRs, mat. reservations,...)
=
available stock
shortage occurs if available stock is negative, that is, the requirement quantities are greater than expected receipts and stock quantity.
so, system specifies the date of the issue (for example, customer requirement, planned independent requirement, reservation, forecast requirement) as the requirements date.

Exclude Stock Transfer from MRP Net Requirements

Hi,
Is it possible to exclude the Stock Transfer Orders from the Net Requirements generated by MRP? I want to base the requirements only from historical consumption. In my Stock/requirements list (MD04) for example, the Requisition generated by MRP increases in quantity since there are open Stock Transfers which are to be served by that plant to other plants.
Regards,
Lee

Nazrin,
Availability check configuration (OVZ9) has no impact on MRP. MRP relies on its internal rules when it is performing its net requirements calculation. You have very little control over which elements are included/excluded.
You can exclude selected storage locations from MRP planning. Stock and reservations against these storage locations will therefore also be excluded.
You can exclude a material from planning, change the material master MRP type to ND.
Your best bet, though, would be to set your PM planning process up such that these materials never create the reservation in the first place.

MRP Net Required/Available Qty

Hello Gurus ,
I am carrying out MRP at plant level .After that MD04 We are analysing the result .We are developing Z report where we need to show Net Required Quanity(-) or Avaialable Quanity .We are using MDKP/MDTB table .
1.Material Requirement Planning No xxxxxxx is not getting updated in MDTB table .I am getting MRP Table no from MDKP using Plant /Material Combination .
2.What is the SAP Table -Filed name to retrive Net Required/Available Quatity (Planned quantity on the time axis that results from comparing receipts, issues, and current warehouse stock)
Thanks and regards

MRP net requirement calcualtion for Lot sizes

Hi all ,
Can some one help me on this ..
I want to set up the MRP for the Raw materials Procurement .
for this i want use MRP type as PD and lot size as WB Weekly lot size .
but as per the requirement the MRP is run daily , i need clarification on certain things such as how does the system calculates the weekly lot size ? say if the requirement is converted into PR on the first day of the MRP run ,followed by that if the requirement varies does the system creates a new PR or it changes the Qty in the existing PR if its was not converted to PO .
what are the stock types considered during PR creation and how are the delivery dates determined during the PR creation ?
thanks ,
ksr

Hi Chris
You can try to set up a maximum lot size and a takt time on the material master.
Take a look on the F1 help of this field on the material master:
Takt time
If a requirement quantity (for example, for capacity reasons) cannot be procured in a single lot, you have to schedule several receipts. In conjunction with the overlap indicator in the lot size (set in Customizing for the lot size), you can use the takt time to specify that these receipts are offset, that is, that they are delayed by the takt time.
You enter the takt time in workdays.
Use
The system uses the takt time if a requirement is covered by several receipt elements due to restrictions on lot size such as maximum lot size (with all lot-sizing procedures) or rounding value (with fixed lot size with splitting).

Net requirement calculation for Sales Order

Dear Experts,
I have configured a strategy comprising both( KE,040) and (LSF and 100), say the strategy is Z0.But the system is not doing net requirement calculation for the dependent requirement(always proposing Pr Req though there is stock).Checking group and checking rule, I have created like the standard PP order.Will anybody Pl. guide me regarding this?
Regards
Reshmi

Hi,
1. The MRP group or the strategy group in the MRP view of the material master record determines what requirements type is used.
If you have not specified this information, the requirements type will be selected through the item category of the sales order item and the MRP type in the MRP view of the material master record.
If you have maintained both an MRP group and a strategy group, the system uses the strategy group (precedence to strategy group).
You can enter the strategy group directly in the MRP view. If you have specified a strategy group, you do not need to enter an MRP group.
The configured Strategy group need to be copied from a standard Strategy and even if you group many Strategies(Max 7) you ned to check the req Type assigned to it .
2. The item category is derived from the item category group in the Sales view of the material master record and from the order type of the sales document. Together with the MRP type in the MRP view of the material master record, the item category determines what requirements type is selected. The MRP group in the material master record is irrelevant here.
The advantage of this method is that the selection of the requirements type depends on the business process (such as quotation, sales order, or repair).
All the above Points need to checked in your case

Rescheduling horizon impact on net requirement calculation

Dear MRP experts ,
What is the impact of Recrudescing horizon on net requirement calculation .
Regards
Sasikanth

Dear Sashikant,
The rescheduling check is used to change the dates of already existing firmed receipts not planned on the same day as the requirement to suit the requirement date.
If you look at MD04, the rescheduling date is based on the Stocks Requirement date.
In the net requirements calculation, the system checks whether warehouse stock or firmed receipts are available to cover requirements. If a material shortage exists, the system usually creates a new procurement proposal.
Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
hope it helps. please revert back.

Alok Tiwari

Net requirement calculation

Dear Gurus
In Net requirements calculation, Safety Stock, Recipts (Purchase Orders, Production Orders, Firmed Procurement Proposals), Requirement qty(Pir, Customer requirements, Material reservations) are considerd
In My Situvation, I want to exclude considering Safety stock while doing net requirements calculation
Kindly tell me the setting i have to do
regards
palaniappan

Dear Planiappan,
In IMG Production + Material Requirements Planning + Planning + MRP Calculation + Stocks + Define Safety Stock Availability maintain 100% in AvSafetySt field. So in planning your 100 % safety stock will be considered.

Open Purchase Orders not considered as requirement for MRP Run

Hi ,
We are facing a issue of Open Purchase orders not appeared in Stock requirements list and also it is not considered as requirement for MRP Run against reservation.
As aresult for a reservation demand of 10 units we are ending with Open POs 10 units and a additional planned order 10 units.
Material Type : ERSA
MRP Type : PD (or VB)
Lot size : EX ( HB if MRP Type is VB)
Could you please throw some light to correct our settings to MRP to consider Open POs?
Saravanan

Can you check to see if there is a re-order point set up for this materia? That could be causing the problem too.

Incomplete Sales Order requirement to MRP

How to stop transferring Blocked Sales Order requirement to MRP?
We have scenario there we entered 100 line on orders, due to one or other reason we need to block the orders and do not want to transfer the requirement to MRP till the time the particular blocked removed manually.
How to do this? There is suggestion to use VOFM - Routine for transfer requirement. But not sure as that is the solution.
Thanks
PP

Hi,
Define a new delivery block whee check the Confirmation and assign the block to the order. System will not pass the requirement to the MRP.
Path: LE >>Shipping >> Deliveries >> Define reason for blocking.

Scheduling Agreement -Schedule line should not pass the requirement to MRP

Hi Friends!
As we all know the scheduling agreements is outline agreement with future schedule lines, with this system will pass the requirements to MRP for the schedule line which is even after 5 years, so my requirement is if the schedule line date is above 15 days from the current date then requirement should not pass to MRP.
solution which we gave is, SA initially will determine the schedule line category as CN (which will not transfer the requirement) and a batch job program will run daily and it will check for each schedule line if any of the schedule is with in the 15 days from the current date then it will change the schedule line category from CN to CP.
Now the problem is , by using Batch Job which program I have to call to change the schedule line category?????
1. we tried BAPI_SALESORDER_CHANGE but when we are changing the CN to CP it is not performing ATP where as if we do manually it is performing.
2. we tried BDC but here also we facing some strange problem i.e. while recording the ATP screen is not populating where it is coming while doing manual.
Can someone let me know which one program we should call in Batch job to do this change.
Regards
Nath

Hi nath,
i also failed in changing shedule line category in userexit and in BAPI.
in one case, i succeded in doing it with a bdc after MV45AFZZ / userexit_save just bevore the datas are reset but after the commit-work is processed.
the other possibility is, to change the accepted amount in userexit RV03VFZZ / USEREXIT_AVAILABILITY_OUT.
3. possibility is, to block the order with a delivery - block , same as the credit-control-block. This block can be set in MV45AFZZ or perhaps in BAPI too.

Dont want dependent requirement after MRP

hi all
I dont want dependent requirement after MRP?
means A is a header material and B.C are the component
after MRP run system should be created requirement of component item.
so wht r setting required?
plz guide me

Hi,
First you ask how can you carry out settings not to get DepReq for your components than you say system should create requirements for your components.
Please give a clearer picture of your situation and make your question more clearer.
How do you procure your goods (if you do not use MRP)?
If you do not want DepReq for your goods you can:
- remove them from the BOM (use them as text item, use design BOM - I do not know your situatio)
- you can set the MRP type in material master as 'ND' (not planned) (MM02 > MRP1)
Please give more information.
Thanks,
Csaba

Credit Hold and the Passing of Requirements through MRP

We are implementing a new process by which instead of putting a sales order directly on a plant which will do the assembly (and where the production order is created), we putting a process in place where we place a sales order on Plant XXXX, but after MRP runs, the requirements will be passed on to Plant YYYY, where a Production Order will be created.
The issue we have run into is that even though the sales order may fail the credit checks, once MRP is executed the requirements to go create the production order are passed on to Plant YYYY. We do not want this to happen. Our goal is to put something in place which will prevent the passing of requirements once MRP is executed UNTIL the sales order has been released from credit hold.
One thing we were thinking of doing was putting a user-exit in place to change the schedule line category from CP to CN to prevent the requirements from being passed on (when the order was on credit hold) and then changing the schedule line category to CP (once it was released from credit hold). However, this seems very messy to accomplish. I would think there would be a better way of getting this done, as opposed to changing the schedule line categories on the order.
I have read several threads that discuss using a VOFM routine to satisfy my requirement, but am unclear as to where this would be implemented and how would it prevent the requirements from being passed when MRP is executed. If anyone can shed some light on this for me, it would be greatly appreciated.

Hello Tom,
you can review the note 744305, which contains some hints how to prevent MRP requirements for the credit blocked sales orders.
Hope, It helps you.
Best regards,
Lela

Is it possible that we generate material requirement in MRP at company code level?

We want to generate material requirement in MRP at company code level, what is the possibility or any work around.
Thanx in Advance.

Hi Mirza
This is not possible on the standard system. The highest planning level on MRP is the plant.
It has been discussed on the following thread, where BAdI MD_CHANGE_MRP_DATA was proposed as a solution, however, the logic to be implemented on this BAdI is very complex:
MRP Run considering Stocks for Multiple Plants and Requirement maintained for Plant Cluster
If you want to know more about the BAdIs available on MRP check the following document:
BAdIs for MRP
Another alternative is to use flexible planning to plant at company code level, then disaggregate the planning to the plants and transfer the result to demand management and MRP.
See the following thread for details:
