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.

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.

MRP Net Requirements calculation in External procurement Vs STO

Hi gurus,
Lets say I have a FG 1234 which has raw component 9999.
Case1:
Setting for 9999 is externally procured.
I have a stock of 50 pc for 9999.
I got order for 60 pc for FG 1234.
so system will only create purchase reks for 10 pc of 9999 as it already sees 50 pc in stock.
Case 2:
Setting for 9999 is externally procured but from one of our own plant (Using SPK 40)
I have a stock of 50 pc for 9999.
I got order for 60 pc for FG 1234.
will system create STR for 10 pc of 9999 as it already sees 50 pc in stock? or will it create STR for 60 pc without checking stock in the ordering plant?

dorian661 wrote:
SPK 70 will not create an STR. Stock of 9999 will be checked in supplying plant. In case there is a shortage, a procurement proposal will be created against the dependent requirement here. Stock is not checked in ordering plant. You will notice that dependent requirements for 9999 will be seen in the supplying plant.
Dorian,
Thanks for the reply. so are you saying that in SPK70
In ordering plant - MRP will not look at the stock situation for that material
In supplying plant - system will check stock requirement and create dependent requirement for the shortage amount
and in spk70 case, against what element is the delivery done to the ordering plant? in spk40 delivery is done against STO.
Thx

Net requirement calculation considering stock ( Strategy 52 )

Hi All,
we are using the planning strategy 52 for process industry and according to the standard functionality the stock of finished product will NOT be considered when MRP run and consumption.
For various reason like customer return we might have the stock of FG. when forecast is finalized and PIR is build in demand management MRP will generate the planned order (type VP) based on the consumption logic. but if stock exist system will not consider it and continue to generate the dependent requirements for the raw material. this is really not acceptable by my client. we want the MRP run considering the stock of FG whensystem generates planned order for PIR.
Is there any other way to fix this issue?
we try to use user exit and set consumption indicator 4 for requirement type of VSE.but we failed. the answer is PIR ONLY consumes the requirement elements. Stock somehow a receipt element.
any pointer is highly appreciateed.

Dear,
Stg 52, will create planned order equivant to the PIR created. and when sales order is created, the planned order is created.
Hence the wayout is use stg 40. this will suit your requirement, create PIR and run MRP. Planned order is created.
Do not convert the planned order to production order and give this autjorization to one who can take decision in shopfloor and coordinate.
You can also use stg 74 ...just see the help link

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.

I followed the same procedure of reverse calculation from MRP pricing calcu

hi,
sap gurus,
i followed the same procedure of mrp calculation but
MRP Pricing Procedure:
Go through the following:
I will brief your requirement in short
MRP = 1012.5/-
VAT = (1012.5/1.125) = 900/-
so price before discount will be = 900/-
discount given at the rate of 10% = 100/-
Initial Price = 1000/-.
1. Create condition types as below:
ZR00 for price
Condition class = B
Calculation type = C
Plus/minus = A
ZSET for settlement (to knock off the effect of ZR00)
Condition class = A
Calculation type = C
Plus/minus = X
ZWST for tax
Condition class = A
Calculation type = H
Condition category = D
Plus/minus = X
Z007 for discount
Condition class = A
Calculation type = H
Plus/minus = A
ZDUM for net price
Condition class = A
Calculation type = A
Plus/minus = A
YWST for tax (to knock of the previous effect - to be used for posting to G/L)
Condition class = A
Calculation type = A
Plus/minus = X
YOO7 for discount (to knock of the previous effect - to be used for posting to G/L)
Condition class = A
Calculation type = A
Plus/minus = X
2. The following will be the pricing procedure configuration:
Step......No........Cond Type........... From.........to..........Man.........Req........Sta................Acc Key
10........0..............ZR00..................--..........--..........-...........-........---.................ZDU
20........0..............ZWST..................10............19...........----.............X............X...................
30........0.............text.......................10...........29...........---...........----.........X
40........0.............Z007.....................30...........39...........-----.............X............X
50........0..............text.....................30............49...........---...........-----.........X
60........0............ZSET.....................10...........19...........----............X............--.................ZDU
70........0............ZDUM....................50...........59...........----............X............---...............ERL
80........0............Y007.....................40...........49...........----.............X...........---...............ERS
90.......0..............YWST..................20...........29...........-----............X...........---................ZWS
ZDU - dummy account key for posting extra not required items.
ERL - account key for price
ERS - account key for discount
ZWS - account key for tax.
3. Condition records in VK11
Condition type----
Condition record.......
ZR00........................................1012.5.....................INR will be positive (1012.50 +)
ZSET.......................................100%...............................will be negative (100 -)
ZWST.......................................10%................................will be negative (10% -)
Z007.........................................12.5%.............................will be positive (12.50 +)
ZDUM.......................................100%..............................will be positive (100% +)
Y007.........................................100%.............................will be negative (100% -)
YWST.......................................100%.............................will be negative (100% -)
Condition records for Z007 & ZWST will be decided as per the conversion required. You will first have to manually calculate the amount for the condition type.
4. I create a sales order for single quantity for an item & the pricing will be as under:
ZR00 = 1012.5 (dummy account) - positive
ZSET = 1012.5- (dummy account) - negative will knock off effect of ZR00
ZWST = 112.5- (negative & no posting)
Z007 = 100 (positive & no posting)
ZDUM = 1012.5 (positive & posting)
Y007 = 100-(negative & posting)
YWST = 112.5 (positive & posting)
but its not throwing any condition records for ZWST and YWST
can any body help me
plz

HI,
Plz try Routin for Vat formula.
i am worked on MRP pricing but in our case formula is different.
eg.: If i want to calculate VAT for B=1000 Rs. it is like
A=1000 * ((100/100 + (12.5- VAT 5)))
= 889
VAT (Value) = B - A = 1000-889 = 111 which is passed to GL account.
For that we developed one Routine with the help of ABAP and assign to Pricing Procedure.

Pricing - Requirment / calculation type / base value

Dear Friends,
Thnaks for the support and guidance provided by you for my previous posts
In Pricing Procedure we give Requirment, Calculation type and Alternative formula for condition base value, I would like to know where do we exctly define all this?
Or are they standard? If standards where we can see how they works?
Regards
Vishal

Hi,
go through the below Examples for better understanding ..
Example: 1
Condition Type: PR00
Requirement 2 Item with Pricing
Purpose:
This is an example of a pricing requirement. This requirement is met if the document item category is relevant for pricing and no previous condition in the pricing procedure has set the condition exclusion flag. This requirement can be assigned to condition types in the pricing procedure to avoid unnecessary accesses to the database when an item is not relevant for pricing or a condition exclusion indicator has been set.
Example: 2
Condition Type: Net value
Calculation Type: 2 Net value
Purpose:
This is an example of a condition value formula. This type of formula can be used to influence the value shown for the condition in pricing. A condition value formula is assigned to a condition type or value line in the pricing procedure.
Formula '2' sets the value equal to net value that has been calculated so far for the item in the pricing procedure. It contains the amount excluding taxes.
Example: 3
Condition Type: R100
Alt.Condition Base Value: 28 (100% Discount)
Purpose:
This is an example of a condition base value formula. A condition base value formula can be used to influence the basis the system uses when computing a pricing value. A condition base formula is assigned to a condition type in the pricing procedure.
Formula '28' sets the rate of the condition to a 100% discount. This formula was delivered with condition type R100 to support free goods functionality.
