MRP with reorder point and safety stock and planning calender issue

Hi,
We are using currently MRP type PD and using Scheduling agreements and after the demand management changes when ran MRP the delivery quantities are fluctating in higher range and vendor complains about it so to avoid this we are constantly changing GR Processing days in material master? how can we avoid the drastic changes on the order quantites on scheduling agreements with out changing GR processing days.
For example : we constantly manufacter 480 vehciles per week and some time because of holidays it will be 320 or 560 per week then the forward scheduling agreement quantites instead of 480 parts week(twice a week delivery) goes up and down and vendor needs a at least a range for his prodcution?
I was thinking to use Reorder point but when i changed the MRP type VB then i cannot see forward scheduling agreements at MD04? does MRP type VB or V1 will allow forward scheduling also like 120 days ahead of planning?
Appreciates everyone time and help.
Thanks and Regards,
Siva

you can use MRP time fence to restrict the changes in planning data for specified horizon. For example If MRP time fence = 30 days, no changes in planning data will be allowed for coming 3o days unless you manually intervene.if any new requirements came in this period , they will be planned automatically at the end of this period only.

Generic Delta with numeric pointer (Without safety interval and no field)

Hi
We have problems with Generic Delta extraction. Our previous Dev has created the data source with numeric pointer as the data source without any safety interval and without any field for numeric pointer selection even we have the date field (creation and change dates in view)....
He created the generic delta with numeric pointer and Additive delta selection on top of view (EKKO,EKPO and EKKN). So we are missing lot of records. Now I need to fix this asap, I have done generic delta with timestamp and cal day with change/creation date.
Now in order to fix our delta loads should I use the cal day as the delta pointer with change or creation date already available or is it ok to use numeric pointer with additive delta and safety lower limit as 10 or 20 with upper limit blank?
Also Should I use any field in the field nm section or is it ok to leave it blank ? Please advice...
Note: I checked the missing delta records in ECC and the change timing is in the afternoon and our load time is only night...We also have several other data sources with same settings (numeric with no safety and no field) but it is not giving any issues.
Thanks

Safety stock and safety period

Can anybody help me in understanding the effect of safety period in MRP..
CAn anybody give me an explanation with numbers so that i could test and understand..
Please help me out..

Dear
There are plenty of earlier posting on Safety stock and safety periods .
Safety Stock : This is one kind of Un-restricted stock which will be used to full fill the un-expected damand for any material apart from the normal stock .Safety Stock calcuation depends on requireiment .It can be pre-defined ( manual safety stock -MRP3 view-Safety Stock ) or Automatic Safety Stock based on the MRP Type set up in OMDQ.If you want automatic safety stock , then it will calcuated based on Forecasting view parametrs , forcast model , MAD, BASIC value calcualted wheil excuting Forecasting collectively or individually .
Safety Stock Calcualtion happend based on following CONDITION :
1.MRP type should be Forecast Base MRP -VV,VB,VS,V1,V2.Here MRP type calculates the Automatic Safety stock based on the Forcasting View Maintained in MM02 with proper Consumption History .( 261,501 etc update control in MMR through OMJJ set up --Please check MMR Forcasting View -Cosnumption Histry at least 6 months are there or not ?)
2.In MRP Type -SPRO-MRP-Check MRP Type -Select any one of the MRP Type like VV , you will find that Calcualtion of Reo-Order Point and Safety Stock Check Box Ticked .Based this set up and above Forcasting view , safety Stock will be calcualted with certain formaul .Here in the Material Master MRP3 view u need to maintain Service Level Percentage of that Material whcih will be consideredr as Service level factor to calcvualte the Safety Stock automatically based on the MAD and Basic Values calcualtion in Forcating View Individually (MM02) or collectively in MP38 .
Hope this above facts will help you to understand the calcualtrion of Safety Stock .
Formula : Safety Stock = R x Sq.rt. W x MAD
Safety Stock = R x W x MAD

Automatic reorder point and safety stock caluclation- MRP type:V2

Hi,
I want the system to calculate reorder point and safety stock. To simulate this i created one material with
MRP type:V2, service level as 97%, Forecast model:D,Hist. period:12,Forecast periods:12, and I entered
the historical value for past 12 months as 100 nos in material master.
04.2009     100
03.2009     100
02.2009     100
01.2009     100
12.2008     100
11.2008     100
10.2008     100
09.2008     100
08.2008     100
07.2008     100
06.2008     100
05.2008      100
Then I went to MP30 and executed the forcase.When I checkd the material master the system has calculated the reorder point as 14 nos. But there is no value updated in safety stock field.
Now I have two questions.
1) How the system has arrived the reorder point value as 14 nos.
2) Why there is no safety stock updated in material master.
Could u please clarify this.
Thanks and Regards

Hi,
This is further to my preivous mail. I have changed the consumption values and now i am getting the safety stock.
MRP type:V2, service level as 97%, Forecast model:D,Hist. period:12,Forecast periods:12, and I entered
the historical value for past 12 months as.
04.2009     100
03.2009     80
02.2009     110

07.2008     92
06.2008     101
05.2008     100
After executing the forecase the sytem has calculated the below parameter.
Basic value:95.759
MAD:11.448
Safety stock:10.252
Reorder point:23.658.
Can anyone explain me how these calculation arrived.

Static or Dynamic Reorder Point and Safety Stock

Hi,
In a retail scenario, what would be the advantages over the other of setting a static or dynamic reorder point and safety stock?
The MRP type used is Time Phased Planning, but whether to let the system automatically set the reorder point and safety stock is the question. What should be considered in implementing this?
Regards,
Lee

hi,
As far as i know is static means manual entry of reorder point.
The dynamic or automatic reorder point is used for Forecast based planning...
the sysstem wii automatically calculate the reoder point evrytime there is the forecast run.
So, it dependig on ur scenario , select either manual or automatic.
First entry for both is always manual entry....
hope u got this..

Report on current stock and safety stock

Hi,
I want to have the report on current stock and safety stock.
In MC.9 it gives wrong safety stock. When I go to cross check the safety stock in material master & in MC.9 I see differences.
Thanks,
Kiran

You can user tcode MC.9 or MC.5 to know valuated stock available at given plant. Stock lying in Returns (MB52) will not be a part of this report as it non-valuated stock.
The stock in the accounting view of the material master considers stock at plant level including stock in Transit (Intra & Inter plant stock trasnfers) & special stock like stock issued to vendor , consigment stock etc which is valuated at plant level.
whereas and stock in the plant stock view of the material master does not consider such special stocks hence there will always difference in both veiws.
For Physical stock as on particular date you can consider MB5B report with radio button "Storage location/Batch Stock" wherein you will get Quantity issued & Qunatity received in those SLOC along with Opening stock & Closing stock for the specified period.
use tcode
MBLB to know stock at vendor.
MB54 - Consignment Stock.

Safety stock and min safety stock

Dear all,
CAn anybody explain me the functional difference between safety stock and min safety stock?
And what is the meanng of safety time?
Karthick

Hi,
Safety Stock:
The quantity of stock to satisfy high requirements. The purpose of the safety stock is to prevent material shortage.
Safety stock as the name suggest is the stock level till which the dead stock or stock out situation will not arise (probable figure based on past data maintained in master).
As such this figure is not stock, it is cut-off figure maintained in master which is used for Planning and once the stock level dips below this value, you can configure system to generate PR, orders automatically. It has its relevance in MRP and CBP.
Safety stock is not used in production.
Minimum Safety Stock
    The quantity that defines the lower limit for safety stock. This value cannot be exceeded.
    The safety is checked to see if it is greater or equal to this lower limit.
    The lower limit is checked if you use an availability indicator which shows, according to customizing settings, if the safety stock is to be calculated again in a forecast. If the safety stock is lower than this level in forecasting, the safety stock is automatically increased to the value of the lower level.
The safety stock must always be greater or equal to this lower level (minimum safety stock)
Hope this will help help you.
Regards,
Pavan

How much to order , reorder point and Safety stock calculation in SAP?

Existing Client is Distribution company , the Challenge is how much order , when to order and how much safety stock we need to keep for Material in SAP?
Limitations with Client System:
u2022The existing system does not enable purchasing to have visibility to firm (open sales orders) and planned (customer forecasted) demand for a material.
u2022If a sales order is placed that consumes all of the inventory available, the purchasing department is not notified automatically to replenish the stock
u2022The system in place currently does not enable the organization to maintain a level of safety stock.
u2022If inventory is logically allocated to a priority customer based on their forecast, there is no way to ensure that inventory is reserved for the priority customeru2019s orders u2013 other sales orders often consume it.
u2022If a material is backordered with several sales orders waiting for parts, the sales orders are allocated based on earliest requested delivery date upon receipt of the part; there is no way currently to allocate the stock across the open sales orders if it is determined that is the appropriate course of action.

Dynamic Safety Stock and Calculate based on past consumption

Hello experts,
I have set up my coverage profile in configuration for dynamic safety stock. However, the value is going off of the current net requirements in the system. How do I set it up so that the target stock level (DSS) is determined by 30 days of our past consumption and so many days of near future requirements?
I assume I need to set up the MRP 3 tab in a specific way. These materials that will be using dynamic safety stock are not forecasted, therefore, the material master had PD as MRP type (not VM or VV as discussed for setting DSS with forecasted materials), lot size of DY, and the coverage profile.
Please let me know.
Thanks.

Hi,
Hi the configuration should be like this..
First Create range of actual coverage profile SPRO and enter the following data.
Period Indicator - M
Number of Periods - 2
Type of Period length - Working days
Number of days per period - 30
Range of coverage in the first period - target - 30
Then assign this profile to the material in MRP3 screen in the field range of coverage profile field.

Prasanna
