Exception message 10 and safety stock
Hello
When I have a ressource in the past (we have this case), and if the safety stock is not complet, the exception message is "10" (reschedulling in) without date.
Normaly the result should be exception message "15" (rescheduling out) with a date.
Why have I an exception message "10" without date ?
Is it the custo, but I found nothing ?
Hi Christian,
I've seen this myself, and believe that it happens only if you allow start in the past and have got insufficient coverage for safety stock.
I guess it doesn't have a date because of the start in the past, which will set availability date even today. Try to change the "start in the past" indicator, and see what happens.

Mario

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,
KiranYou 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.

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
PurushothamanHi,
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
01.2009 85

08.2008 90
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.
Thanks and regards

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,
Leehi,
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..

Exception message 20 and reorderpoint
After searching for information on why SAP gives message 20 if the net requirement is above the reorderpoint i never to the needed information.
Yes i am able to see that if reorderpoint is 100 and due to a lot size of 50 pc then naturally we will be above our reorderpoint at the arrival of with this PO. In reality what we see it that sap suggest purreq for replenishement considering the reorderpoint and the lotsize . we convert and with the next MRP SAP suggest to cancel the same order which it propose to replenish!. Again yes we are above the reorderpoint due to the lotsize - but why would SAP use the reorderpoint as a max stock level - which it clealy is not.
I need to understand if there somebody has been looking into this issue and how they manage to avoid these message 20 but without exculding them in a spereate group as we do use this message for materials that has other parameters. Are there any oppertunties to customize a limit for when message 20 should appear for a reorderpoint or can it be ticked of as i makes no sense.
Thank you in advanceMy Settings are
MRP type VB - manual reorderpoint
reorderpoint 1010
safety stock 135
Lotsize 1000
net requriment stock : 1893
Open PO for 1000 pcs
I made an example where i compaired SAPs calculated reorderpoint V1 with the settings we have to see if the messages disapeared
And my conclusion was
The reason for all of these message 20 is because the safety stock and reorder are inconsistent. As soon as I get SAP to calculate the SS and reorderpoint then message 20 disappear. The GAP between current safety stock 135 and reorder point level 1010 is not equal to the daily requirements *LT + SS it is much higher. SAP sees that the stock /PO comes home before you reach you safety stock level u2013then it considers you to be overstocked ??
With SAP calc: 1586 (net requirement when PO with 1000 pcs) - 438 (SAP SS) = 1148 u2013 1233 (SAP reorderpoint) = 85 units difference (target must be to get a 0 here)
With current manual reorderpoint replenishment : 1893 u2013 135 = 1758 - 1010 =748 units difference u2013 sap considers that overstock?? and therefore a message 20??
I am completely wrong or is this how it works? -
Different Exception messages in MRP list & Stock Requirement List
Hello Experts,
When I run MRP and then look at the stock Requirement List & MRP list for the same material, I see different exception messages in these list.
I noticed that any of the exception messages in Exception group "7 - Exception during rescheduling" (ie, 10-reschedule in; 15-Reschedule Out; 20-cancel process; 30-plan process according to schedule) is not appearing in the stock requirement list even though they appear in the MRP list.
Does any configuration affect what message group can appear in Stock Requirement List & MRP list?
Please advice.
Regards
TomHi Tom,
For exception message - 62, just do the below checks -
Some of the reasons as to why you may find this exception message is because the backward scheduling can drive the start date in the past so far that:
- there is no valid BOM as of that date
- one or more of the work centers are not valid on that date
- there is no valid factory calendar on that date
Check the scheduling formulas in your work centers that are set up, and/or to specify for the material master a fixed lot or a max lot size so that planned orders result with realistic lot sizes.
Also you can set up MRP to only run on basic dates for your overall run, and to follow up with an MRP run which generates capacity planning only within the planning horizon, such as NETPL. You would need to configure the planning horizon so that it specifies a time frame over which capacity planning is to be done.
Also check the note : 88505 - Planned order upload generates exception message 62
In short, do a thorough check of the parameters maintained to ensure there is no inconsistency in the master data.
Check & revert.

MRP exception message 64 and planning strategy group 52
Hi Gurus,
I have done extensive search online in the forum to find the route cause why we are getting MRP exception message 64 for a specific material in one of our plants. This exception message does not occur for the same materials which is also produced in another plant.
I was just wondering whether the planning strategy group of 52 in MRP 3 view would have any effect on the frequent occurrence of exception message 64. I know that the 64 message occurs when the routing time is higher than the in house production time. If that's the case where to look for in routing to correct this, apart from this do we need to look at work centers and other details. I'm not a PP person but still was curious to know see if i could take a shot at it.
Also the MRP settings that we follow in the plant where this problem does not occur is NETCH, Create PR - 2, Schedule lines - 3, create MRP list - 1, Planning mode - 3, scheduling -2
in the plant where the 64 message occurs quite often is Netch, Create PR -2, Schedule lines - 3, create MRP list - 1, planning mode - 1, Schdeduliing - 1
I was thinking do MRP settings and planning strategy group would have any impact on why we are getting the 64 wexception message
Because of this 63 exception message, the downstream components are getting wrong signals.
Thanks
RaviHello Ravi
Generallt, exception message "64 - Production finish after order finish" is triggered when the order start date is in the past and system automatically changes to forward scheduling to calculate the finish date.
Note 1913017 explains how the order basic date is calculated and adjusted in case of forward scheduling, however, you are using strategy 52 and this is a very special scenario, whever VP planned orders are generated.
The VP planned orders will always be adjusted to the requirements date even if the requirements date is in the past. This is a special feature in the planning segment, since these orders are only kind of 'virtual' planned orders. These orders only have to provide the demand requirements for the components in time.
Therefore, there is a relationship between strategy 52 (VP planned order) and the exception message observed.

Did anyone have idea how to use safety stock with forecast in such a way that System should always raise PR for quantity of forecast only , if forecast in not available or less then the safety stock quantity PR will be raise with safety stock quantity -
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.
Thanks
SwethSweth, you are asking for consulting, and in my opinion it is way beyond what can or should be reasonable to achieve in such a forum. You are asking complex questions, that most probable have more than one possible answer.
I suggest that you get on-site help from a knowledgeable and experienced consultant. These are crucial business issues, and should be dealt seriously. -
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.

One purchase requision for PIR and safety stock
Dear All,
We have following scenario:-
We have maintained safety stock of 50 Pc for A material.
planned delivery time is 5 days.
PIR of 100 Pc with date 15/9/10
Lot size maintained in material master is MB
Now when I take MRP run on 20/8/10 system creates two PR
50 pc on 21/8/10
100 pc on 15/9/10
Our requirement is to create one PR instead of two.
pls suggest.
with regards,
pradeepHi,
Lot size is MB, the demands are in 2 different months & hence system is creating 2 different PR's.
If you want it to be under same PR, then you might consider moving the demand in september to august if its possible or think of having a custom Lot size which is bi-monthly.

Is there any bapi returns dynamic value of reorder point and safety stock
Hi all,
Is there any bapi returns the runtime value of ROP and SS by passing changenr/objectid taken from CDPOS.
if exists please send me with code.
Thanks
PRR Rhi,
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..

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,
Sivayou 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.

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,
Karl
