Requirements calculation

How do is set-up the Available Inventory in SAP? the formula is Available Inventory = On Hold + Released u2013 Allocated
How does SAP calculate the MRP requirement? Can it include Open Purchase Orders & Safety Stock?
Formula should be like this:
MRP Requirement = Avail Inventory - BOM Required Qty u2013 Open PO + Safety Stock Requirement

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.

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

Rough -cut plan with capacity requirment calculation

Hi all,
We checking SOP with rough-cut plan
We created Rough-cut profile in mc35 for our bottle neck work center with base quantity -1 and time span - 1
then we selected new work center (there is no existing cap req). and assigned base unit measure:min.
and we assigned 1min for each day and saved the profile.
Now we went to mc88 and checked the material's active version production plan. (period split- DAY)
in View -> capacity situation -> rough cut planning -> show.
System calculates some capacity requirement for our production plan.
Say for tomorrow's date i given 1000 qty - production plan.
but system showing capacity req
Work center: TESTWC3                  Plant: 0001         Capacity: 001
Info structur Material          Plant   Order qty     Unit     From              To          Capacity reqmts      Unit
S076            TESTFERT14    0001 1000.000       EA    29.01.2010 11.02.2010   9000.000              MIN
with 9000min and cap load more than 652% ( Actuallly it has to show 1000min as per rough cut plan profile)
Our available capacity of work center per day - 1380 min
We cant understand the capacity requirement calculation in MC88..
Help us out...
Thanks in advance

Hi,
Rough cut planning is genrally done for the group of material say product group, group of workcentre rather than individual material or workcentre.
As standard, in resource table whatever the value you enter that corresponds to no. of days. Each column represents one day.
Pl. refer this link for clear understanding of the same.

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.

2010 server role requirements calculator

I'm sure there are other threads on this my terminology must be off on searching for them.
I have a 2010 exchange environmnet, VMWare, max ____ 2TB. I don't know if I need to say max disk, volume, lun or single storage device. But if the role calc is going to help me I need to input this limit. I have 2 mbx servers, no DAGs.
The calc returns lun sizes of 6+ TB but I can't have luns that large.
How/where do I input the right number so the calc will help me with storage configuration?

Hi,
Found a useful blog for your reference:
Exchange 2010 Server Role Requirements Calculator
http://blogs.technet.com/b/exchange/archive/2009/11/09/3408737.aspx
Collected some information from the blog above:
1. The term LUN utilized in the calculator refers only the representation of the disk that is exposed to the host operating system. It does not define the disk configuration.
2. The LUN Design highlights the LUN architecture chosen for this server solution. The architecture is derived from the backup type, backup frequency, and high availability architecture that were chosen.
3. Most operations management programs have capacity thresholds that alert when a LUN is more than 80% utilized. This value allows you to ensure that each LUN has a certain percentage of disk space available so that the LUN is not designed and
implemented at maximum capacity.
Hope it is helpful
Thanks

Requirement calculation of material in process order

Dear Friends,
we have one raw material whose base unit of measure is maintained as CAR (cartons) and the unit of issue is in EA in material master.
now, when we create the process order of Header material, the system calculates the requirement qty of raw material in EA and this is properly shown when i click the material icon for the details of componen.t
but when i click the icon of material availability check the system gives the message as missing part list even if the current stock fulfills the reqmt. qty.
hereafter when we click the missing part list overview the reqmt. qty is calculated as per the base unit i.e. in cartons , it rounds of the figure obtained and re-converts to the unit of issue as in EA.
for eg.
one carton contains 1472 pcs EA
required qty of x material as per process order is 16000 EA ,
when we click on materials icon it shows the figure as 16000 EA correctly,
but now when we check for material availability and seee the missing parts overview , here the requirement qty is shown as 16192,
system calculates as follows:- 16000/1472 = 10.869 cartons,
here it rounds off to 11 cartons and equivalent of 11 cartons is 16192 EA.
so if, say for e.g. my stock of raw mat. is 16000 EA which can fulfill my reqmnt as per BOM but due to the above calculation shown the release of order is rejected.
please suggest for the issue to get resolve.
thnx in advance
rgds
Amitabh Rathod

Dear Amithab,
Frist thing is always ur base unit of measure should be the minimum one. in ur case u hae done ulta.your BUM sholud be EA and yor altrnative unit of measure should be CAR this u define in material master basic data view. at this piont of time system will not allow u to change unit because stock and other movement document exists.
Now the only solution to get CAR in exact decimals ask ur MM consultant to enable 3 decimal placess for the unit CAR in SPRO, then ur issue will be resolved

How capacity requirement calculated in RCCP in SOP

Hi,
I am executing RCCP (Rough cut capacity planning in SOP) for a material through MC93... I am in the below situation as shown in the below screen shot... in the below screen shot if we consider April 2014 month I understood how available capacity 34819 (MIN) is calculated but not getting how capacity reqmt 397 (MIN) is calculated... can anybody guide me on this how capacity reqmt is calculated....
Thanks
Kumar

Hi,
Thanks for your reply....While creating the rough cut capacity planning profile where I need to mention the qty produced..I will give you my exact situation..
I have resource with six days working. total working time per day is 1339.2 MIN. Total work days in a month are 26 so total available capacity becomes 26*1339.2 = 34819.2 MIN
Now in a month I have a requirement of product is 20,00,000 PC. Machine can produce i.e. capacity of the machine is 1,00,000 PC per day....now my capacity requirement will become like this
total to produce 20,00,000 PC no of days required are is 20,00,000/100000 = 20 days
Per day capacity is 1339.2 MIN so total capacity requirement is 20*1339.2 = 26784 MIN
So now capacity load is 26784*100/34819.2 = 76.92
Now question is where to give capacity of the machine is 1,00,000 PC per day. is it in the RCCP profile header in the base qty as shown below or some other place.... plz clarify....
Thanks
Kumar

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

Automatic KANBAN quantity calculation requirement -reg

Hi,
As of now we enter no.of KANBANS and KANBAN quantity while creating control cycles for the material to be operated through KANBAN. The KANBAN quantity is decided at user level and updated which is causing many discrepencies .
the requirement is can system calculate the KANBAN quantity automatically driven from the requirement calculated based on finished products PIR quantity ?
1. is it possible that when MRP runs for the finished product system calculated the KANBAN quantity for those BOM items of the Finished products which are marked as relevant for KANBAN.
2. if it is possible then what and all settings and other things required ?
3. any side effects?
please provide some inputs
regards,
madhu kiran.
