Mrp requirement qty including safety stock
I have tested and got results as follows with VB/EX:
RO Point = 10 ea
Safety stock = 5 ea
Stock = 5 ea
But the mrp element generated for 5 ea only.
I need to get requirment qty considering the safety stock also.
HOW TO INCLUDE SAFETY STOCK IN REQUIREMENT QTY?

Hi,
the safety stock is relevant when you are carrying out goods issues.
the system will stop you from placing orders against the safety stock (because you don't want to sell this you want to keep it for emergencies) and yet it will allow you to goods issue to a delivery from safety stock (because that is why it is there, to ensure that you have spare items in case of shortages).
You control what can and can't issue safety stock by using different configurations for the availability checks for each function..
So even though the reorder point MRP seems to ignore safety stock it still warns you when you fall below this (with an exception message) and it is still used for goods issues and transfers etc.

Independent requirements within dynamic safety stock policy
Hi Community,
I was wondering if we can setup a dynamic safety stock (coverage profile) without using consumption based forecasting? Our forecast is provided through the SCM DP. If yes, which MRP type should we use?
Many thanks for any feedback,
NoëlHi Noel
Yes, it is possible to use a coverage profile without consumption based forecasting. You can use an MRP type with MRP procedure, such as PD.
See my answer on the following thread for more details about the coverage profile logic on MRP:

Hi all,
1. How the system calculates the Safety stock requirement for the raw materials?
Requirement is,
I am doing monthly production planning for the FG materials. And i want to keep all the raw materials stock as 15, 30 and 45 days stock as safety stock of the respective FG BOM raw materials. Bu the safety stock requirement for the each raw material is different.
How to get the safety stock requirement quantity for the required raw materials?
Actually I tried with coverage profile and the safety time / range of coverage in the MRP 2. But I did not any results. i think I may be wrong ,when I am working with coverage profile and safety time / range of coverage.
Please suggest me the appropriate solution for the above requirement.
Example,
Month April
FG Material (XYZ) 1000
BOM for XYZ
Component Qty stock
RM1 2 100
RM2 1 150
RM3 1.5 500
As per the BOM the actually requirement for the RM1, 2, 3 are 1900, 850 and 1000 respectively.
I want to maintain the safety stock of the raw materials for RM1 for 15 days, RM 2 for 30days and RM3 for 45 days stock based on the gross requirement qty. So my total requirement as per the safety stock requirements is as below said, for the raw materials like,
RM1 is 2000(gross requirement qty) +1000 (safety stock requirement for 15 days) -100 (available stock) =2900
RM2 is 1000(gross requirement qty) +1000 (safety stock requirement for 30 days) -150 (available stock) =1850
RM3 is 1500(gross requirement qty) +2250 (safety stock requirement for 45 days) -500 (available stock) =3250
How to get the above explained requirement quantities for the raw materials like RM1,2,3.

How to make MRP run based on Target Safety stock
Dear Experts,
For our MRP-planned materials with safety stock we would like MRP run to take into account target stock level defined for each month.
for example: we know the target stock level values will be for M1 = 1000, M2 = 0, M+3 = 5000 etc.
MRP should then propose orders to replenish up to the target stock level at the end of each month:
needs for current month = (target stock level defined for current month minus safety stock)
needs for M1 = (target stock level defined M1 minus safety stock)
needs for M2 = (target stock level defined for M2 minus safety stock)
etc
Do you know if there is any simple way to achieve this?
Thanks you!
ElynnDear Experts,
in my company, we are facing exactly the same issue, we would like the MRP to consider a target stock exaclty as described by Elynn. To be more clear, if we could reproduce the TDSS like in SNP in MRP, we'll be happy !.
We imagine already to manage the target stock level in APO DP and released into ECC6 as a different MRP element than Forecast. this target stock should not be considered as forecast neither consumed by any sales order. Only to force the MRP to generate planned orders to increase the final stock when needed. This is only an idea, we have nothing tested yet.
someone have an idea if there's a standard solution for make this ? I mean, why this fonctionality exist in SNP but not in MRP?
thanks for any help

Availability Check required without "Safety Stock"
Hi,
I have a fert material "FG' whose prodn order i am creating.
This FG has a child Component "RM"
Available Stock for RM = 20
Safety Stock for RM = 20
No Receipts / No Reservations exists for RM.
I want the production order not to consider SAFETY STOCK. Hence in OPJJ i removed the Tick "Include Safety Stock".
When i create production order, as per the above setting, it should show " Material Avaliable", but instead it is showing Material Shortage.
Plz guide.
Thanks in advance,

HI All,
I have one scenario for MRP in MTS Scenario.
E.g.
Available Quantity= 50
Reorder Point = 60
Safety Stock = 20
Now the available stock (50-20=30) Stock is less than the reorder level stock after removing the Safety stock.PR is generated and it is converted into PO, PO sent to the vendor. But vendor will take time to send the goods to our plant.
In the same case we have safety stock in stock, I want to use the safety stock available in the system to sell it to the customers because of the urgency. How can i use the safety stock to sell to the customers? What is the Procedure to do it? Please explain me with step by step.
Sure, points will be awarded.in the availability check, in OVZ9...for tyhe combination of ava check and group set include safety stock check box active.
then it will allow you to get the qty in ava check in sd order and you can sell it. -
Whether it is possible to make auto goods issue below safety stock level
Hi SAP Gurus,
I am implementing MRP for generating stock transfer Planned orders from a Main Mother Plant to different Plants. We have defined a Safety stock level for materials at main Plant level.
There is a auto program available for generating auto goods issue against Purchase orders.
System picks up Qty as long as unrestricted stock exists for the material during auto goods issue.
System dont pick up any Qty below safety stock level (manual goods issue works below safety stock level).
We are defining safety stock to meet sudden requirements and have time for new procurement.
But it should allow us to do auto goods issue below safety stock level.
Whether this is possible and what need to be done ?
Thanks and Regards,
R.Velmurugan.Hi Velmurugan,
I don't think auto GR is a problem from safety stock. Auto Gr can be done by two ways.
1. Control key and assigning the control key in operation(Preferably in last operation)
2. In production scheduling profile you can do it. You have to assign the production scheduling profile in material master work scheduling view.

Maintain plant specific safety stock
How to maintain plant specific safety stock for the same material.
Hi swetha
First Go to T : code : MM02 : change Material
Enter plant number for which u want to enter Safety stock
Goto MRP-2
Net Requirement calculation
enter safety stock
Use of safety stock :
Safety stock
Specifies the quantity whose purpose is to satisfy unexpectedly high demand in the coverage period.
The risk of shortfalls is reduced by having a safety stock.
Procedure:
With manual reorder point planning, you can enter a value in the material master record. However, it is merely for information.
With automatic reorder point planning and forecast-based planning, the system determines and adjusts the value automatically for forecasting purposes.
Hope ths solve ur problem
please reward points

Suppression of Re-Order Point Safety Stock Exception Messages
Hi There!
Hope someone can help!?
I need to be able to suppress MRP Exception Message 96 - Qty Under Safety Stock but for PD Only.
Is this possible?
Cheers,
KarlHi There!
We have lots of Raw materials controlled by MRP Type PD, which have Safety Stock Value.
However, quite often although the actual stock is lower than the Safety stock Planners have lots of messages (96 - Below safety stocks). However, although Purchase order reciepts may be late, there isn't actually a problem. As When the PO Reciepts actually happen there is enough stock to satisfy actual demand.
We would like to put many of these Raw materials on Re-Order Point Planning, and manage. But we would like to ignore the (96 - Below Safety Stock) for Normal Items.
Hence, Planners have exception messages for REAL Priorities.
Hope this explains all!
Cheers,

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?
KarthickHi,
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.

Hi,
in our ASCP plan, currently we have items with Safety Stock values manually inserted valid over all planning horizon.
Therefore all the safety stock is NON-TRANSIENT.
Actually we have Priority Based pegging with:
MSC: Include Safety Stocks in Priority based Pegging: YES.
What is appening is that ASCP peg On Hand quantities to FORECAST DEMAND, then pegs other supply type to SAFETY STOCK Demand.
I would like ASCP to peg OH to Safety Stock Demand (DUE on the plan start date) before Forecast demand (due in the future).
Someone knows how to obtain this "feature"?
Thanks in advance.
GiacomoGiacomo,
I'll give you a few pointers, but this may be difficult to achieve. Try this as a test.
I assume you have a constrained ASCP plan. This question wouldn't be as relevant in an unconstrained plan because the demands would just be calculated and priority pegging isn't that useful. .Is that correct, you have a constrained plan?
The key point is that you mentioned is that you have NON-TRANSIENT safety stocks. This means that you are setting a value due today for 100 units and at the end of the plan, you still want to have 100 units of safety stock planned.
ASCP priority pegging logic has these rules:
1. Any supply quantity that pegs to NON-TRANSIENT safety stock CANNOT be used at a future date to peg to real demands. [It's not going to happen]
2. Any Supply quantity that pegs to transient safety stock CAN be used at a future date (when the corresponding dip in safety stock occurs) to meet demands. [This means that it can release the supply and re-peg to a future demand].
Independent Demands have a seeded demand priority by default. The first two below are set by a profile option, safety stock is always the lowest priority ( a number something like 99999 where the higher value is lower priority)
1. Sales Order = 10,000*
2. Forecast = 100,000*
3. Safety Stock = 999,999 (not sure of this internal value)
Set by a profile with a name like msc: default sales order priority
For priority pegging setup instructions, please see the ascp user guide. The basics would be the use of two profiles mso: demand window size and mso supply window size. This determines how ascp will select and sort your supplies and demands for pegging. It starts at the first demand date or supply date and selects that many future days of demand and supply to sort and then peg.
You also setup a priority rule that determines how ascp calculates priorities for pegging. To accomplish what you want to do, you would have a rule like
1. MDS & Sales Order priority
2. Schedule Date
This is a commonly used example. The pegging process will the select the number of days you have chosen and sort the demands based on their prioirty.
Sales orders are more important (to you) than safety stocks, but not forecasts. You want the safety stock to peg the on hand, not a future forecast. This can only happen because you have mso: demand window size set to a number of days where pegging sees the future demand in the same sort. I haven't seen this requirement (SS higher priority than forecast), so you'll need to test my suggestion.
Set the value of MSC: Default forecast priority = A huge number (higher than 999999).
The intent is to make the demand priority the SAME as a safety stock demand. In this case, with the priority rule I suggested, the schedule date will determine the pegging order.
I think this will get you close. You can view the internal proirity calculated by ASCP for the independent demand by selecting that order in the pegging details and then rightclicking to select the properties. The pegging details wil show you the priority value that was used.
Hope this helps.

How system calculate the required qty. after MRP RUN
Hi,
I want to know if we are using MRP Type as PD and also we are calculating automatic saftey stock and re order point qty. after MRP RUN according to which rule formula system calculate the safty stock, reorder point qty. and the required qty. as a PR.
and if we are not using calculate safety stock automatically and if we set safety stock qty. manually in this case how system will calculate the required qty.

Is there any way plan safety stock at subcontractor in MRP ?
When the stock is at vendor ( material provided to vendor)
and if we wanted keep safety stock at vendor by entering safety qty in material master .After MRP run system ignores and planes addition requirements which is unwanted .Is there any way to fix for this issue ?Define Safety Stock Availability
In this step, you define the percentage of the safety stock to be
available for planning. This function is used to avoid a situation where
orders proposals are created unnecessarily by the system to cover small
shortage quantities.
In MRP, the system usually carries out the lot-size calculation for every
shortage and creates an appropriate order proposal or - if already
available - a firm receipt with a rescheduling proposal.
However, it does not always make sense for a new order proposal to be
created for every small shortage. These order proposals must all be
managed, converted, placed in stock and settled. If you want to save
yourself this effort, you can make a portion of the safety stock
available for planning. This has the following consequences:
o An order proposal is not created until the stock level has fallen
below the safety stock available for planning
o If the shortage exceeds the portion of safety stock available for
planning, then the system creates an order proposal in the planning
run that covers this requirement and that also replenishes the safety
stock.
o The portion of the safety stock available for planning can only be
determined using the MRP group. Therefore, to determine that a certain
percentage of the safety stock of a particular material is to be
available for planning, this material must have been given the
appropriate MRP group in the material master record.

MRP is conflicting with Sales order requirement Qty and date
Hi experts,
We have below scenario:
Material has the stock 100. It has reorder point 3 and MRP type V2 (Automatic reorder point with external requirements) and planned delivery time 10 days.
MRP run creates purchase requisition whenever the stock falls below reorder level or/and based on customer orders requirements.
We created first sales order for Qty 80 and delivery date 03/01/2012. Qty 80 is confirmed against this sales order.
We created second sales order for Qty 50 and delivery date 01/31/2012. Now remaining Qty 20 is confirmed against this order. So we have requirements of 30 Qty for this second order.
When we run MRP, it supposes to create Purchase requisition for Qty 33 (30 + 3) including reorder point (3 Qty). As the delivery date for this order is 01/31/2012 and requirement Qty is 30, and planned delivery time is10 days, MRP run should create purchase requisition. But it is not creating.
If I change the planned delivery time to 30 days, it is creating purchase requisition. It is considering sales order delivery date of First order (delivery date: 03/01/2012), but not for second order (delivery date: 01/31/2012).
So MRP is conflicting with Sales order requirement Qty and date.
Appreciate your help in this regard to resolve the issue
