Nexus OSPF cost calculation issue

Hi,
We have core Nexus 7K switch and its further connected to 2 switches via port-channel-1 and port-channel-2.
Now port-channel 1 connected to one of the switch has 4 gig ports and port-channel 2 connected to another switch has 3 gig ports.
We are running OSPF and ‘sh ip ospf int br’, is showing cost for both interfaces as ‘1’. That means both links have equal cost.
Question:
If its IOS, then reference bandwidth will be 100 and both connected interfaces will have OSPF cost as 1 which is understandable but it’s a Nexus 7K switch which has reference bandwidth 40K, why both interfaces have ospf cost as 1?
Thanks

po2 containing 4 ports connected to R2 and po3 containing 3 ports connected to R3.
As these are Nexus, so reference bandwidth on all routers is 40,000
Now when I do the 'sh ip route' cost for both R2 & R3 is 1.
Why R1 not considering that po3 has BW 300000 as compare to po2 ( BW 400000), so routes should be preferred via R2 instead if R3, why its load balancing the traffic on both links.
Why OSPF not calculating the cost considering the port-channel bandwidths.

Interface OSPF cost issue

Image link (the image above looks distorted in the post preview): http://fodder.s3.amazonaws.com/ospf-cost-diagram.jpg
In the test network shown in the diagram I have the following issue that I can't seem to figure out:
Without any modification to ospf interface cost traffic from R8 to 172.16.88.1 (R5) takes R3 --> R2 --> R5 (total metric 67).
This is not ideal because of the f1/0 interface on R2. The path via R3 --> R4 --> R6 --> R5 (total metric 68) is actually preferable but is not selected because of OSPF's baseline inability to distinguish between FastEthernet and greater link speeds.
I am fully aware that I can use the auto reference-bandwidth command on all the routers to fix things but I am testing behaviors of the ip ospf cost command at the moment.
Setting the ospf cost of the f1/0 interface on R2 to 10 changes the path for traffic coming from R8 on its way to 172.16.88.1 (R5). This is desired result. However, the return traffic from R5 continues to use the path through R2 (R2 --> R3 --> R8). This is what is illustrated in the dotted arrows in the included image. R2's interface cost is not being taken into account by R5, which I am assuming is because R5 respects his own interface cost on the link over R2's cost. However, this is producing a sub-optimal return path.
My question is this: Aside from using a route map is there an ospf configuration that I am overlooking that will cause R5 to stop thinking that the path through R2 is preferred?

Hi Colin,
The only way I could solve this was to change the cost on the return path of R5 to R8. It isn't tidy, but setting the ip ospf cost on R2's G0/0 port to 10, changes the cumulative path from R5 to R8.
I changed the reference bandwidth to 1000 in the topology to see how this would changes things. I just learnt that a 'no ip ospf cost' on both int g0/0 and f1/0 on R2, does not change the cost by itself, so had to clear the ospf process in order to affect the cost. Not sure if this is normal behaviour...
With no ip ospf cost configured on R2, and the ref bw changed to 1000, the path from R8 to R5 now takes the optimal path. However traffic R5 to R8 will still take the path through R2. Checking on the cost of G0/0 on R5 the cost is 1.
Great scenario... to get the optimal return path,R5 through R6 to R8, R2's G0/0 port needed manual adjusting to 10, so R5 would not have R2 as the best path to reach R8.
Taking R2 off the shared link of R5 and R6 and having it's own Fastethernet connection to R5 would be the simplest solution? Thanks for sharing Colin.
Cheers, Jeremy.

Bom Component qty & WIP Quantity differ at Trget cost calculation

Dear gurus,
i am facing the problem with WIP at target cost calculation in REM.
My issue is
BOM Component qantity is 9.524 TO and price is 2000 then total cost is 9.521*2000=19048.
but in WIP Report kkas in WIP explation it takes input qty 9.52 T0 and price 2000 then total price is 19040.
Difference is 19048 - 19040 =8
and also when i am issuing actual qty i.e 9.524 in BOM then my price is 19048.00 ant at time of variance calculaton then quantaty variance as 9.52.0-9.524.0=-0.04 then 0.004*2000 =-8
Please suggest solution for this.
Any OSSS NOTE Required
any Quires please revert back

Hi
Rounding differences between target and actual values and quantities are not unlikely to occur and cannot always be avoided but can be minimized.
Small prices and price unit of 1 are likely to cause more of these rounding differences..
The actual credit is simply calculated as price * quantity. The target credit however is calculated during the variance calculation
and based on the sum of all items in the itemization/cost components of the cost estimate and therefore more accurate.
To avoid this I suggest to store the material price with a larger price unit, i.e. 1000
Std cost release stores price upto 2 decimals and target cost calculation goes upto 3 decimals...
Please check also the note 1265918 for more information to this topic.

Shipment Cost Calculation

Dear All,
I know that tariffzone plays a role in determining the price for the freight/Service Agent condition in case of outbound shipment cost calculation
I have the following query in Shipment Pricing.
Can anyone please explain whats the role of the 2 postal code columns in the tariff zone assignment?
Also how & where I have to maintain the data for determining the tariff zone which I have assigned to the above combination.
Please help.
Regards,

HI Dave,
Thanks for the response.
Please note that I have maintained postal codes in my Shipping point also in my customer master.
For the combination of TP Point, Service agent, Shipping type & Country I have made the following assignment.
I have given my shipping point Postal code in both the Postal code columns of Tarff zone assignment (say Tariff) & my customer master Postal code in both the Postal code columns of Tariff zone assignment (say Tariff1).
Now I have maintained the condition records in TK11 for the combination of Depart. Tariff zone/Destn.Tariff zone/Service Agent i.e. Tariff/Tariff1/Service Agent
But my condition record value is not getting determined & when I simulate my shipment cost I am getting the following error message.
Shipment costs not yet calculated
Shipment costs item 000001 w/ ref. to doc. $0001 item 0001
Message no. VY104

COFC - Actual cost calculation error

Hi Friends,
I am a PP consultant and i have a issue with cost calculation at the time of confirmation.
There are production orders that were confirmed in year 2010 and year 2011. For year 2010 costing documents were created but not no costing docuemnts for confirmations in year 2011.
I checked tcode COFC and found error log as : A master record for 1111/ABCD exists only in 2010.(where 1111 is cost center and ABCD is activity type.)
I have checked the validaty of both cost center and activity type & both are valid.
can anyone please suggest what has to be maintained for year 2011 from controlling side.
Thanks In Advance.
Rohit

Hi Rohit,
The similar error i have faced just couple of hours back.
I have checked up the plan prices in KP26 for the activity type and could see that they were not maintained for 2011.
I have maintained the same for the current year and the error got resolved.
Pls see that you are choosing the correct cost centre and activity type combination alongwith the costing version for 2011.

Error in cost calculation for production order

Dear All,
I got error of cost calculation while release of Production Order due to price of some material is not mantain .
What will happen if I release , save the Order with error & do Good Issue ???
Ishwar

Dear Ishwar,
Check the log's created for costing and rectify the same.
I feel its better to rectify the cost related errors and then release the production order and proceed to Good's Issue.
Check whether there is a MAP for all the Raw-materials and an origin group in costing 1 view.
The Finished product must be having a standard cost estimate that's valid for the current period.
Revert back in case of any more help needed.

Doc type is using as same as normal production order and normal production order confirmations and other activities are posted successfully. Iu2019m in a puzzle, regards to this behavior of rework order?
Back ground for rework order:
Rework order was created through trigger points.
Rework order doesn't have any material, it has to pick and settle to original production order; the same was defined at re-work order settlement.
Rework order not doing any cost calculations at production order level itu2019s giving a message as below:

- Items in the BOM
- Display BOM
- Operations in the routing
- Control key in the routing
1. Look at the message log.
2. Check whether a quantity was specified in the confirmation.
Will some one throw some light to come out from this situation and what I missed out and what need to be maintained exactly Plz.
Thanks in advanceu2026Vyas

Hi Mangalraj,
Have check the BOM & Routing for Parent production order costing check box is for both. Coming to rework order doesn't have any material, though it has pulled the some material cost from parent production order. The same can see at production order costs>analysis, but where as costs>itemization not able to see and mesage issued like: object was not costed.
as early mentioned, confirmation level same error.
Hope this may give some idea on this case, thanks for your time on this.
Looking forward some light.
Thanks...Vyas

Material scale price in cost calculation

Hi Experts,
could any of You pls advice me with an 'inforecord scale price' - based calculation?
My calculation - material cost - based on inforecord price, but it is not correct when I want to make a calculation for ex. pilot products. During cost calculation for different costing lot size, I have different material qty requirement. Scale price is exist in inforecord. In the calculation the system always check the scale price of the material - based on the costing lot size in the material master, and do not care about how much the actual raw material need in the calcuation.
Ex. the scale price is 1-100 pcs X USD, 101-1000 pcs Y USD -mat.master lot size: 1000; I have a calculation for 600 pcs - which requires 60 pcs of the raw material. In this case I want the system to have the 1-100 pcs X USD - as actual need on calculation, but the system takes the 101-1000 PCS Y USD - as material lot size. So I really can not check how much the pilot will cost: 100 pcs, 400 pcs etc to produce, but I always have to maintain the component material masters with changing the calc. lot size in material master (first I have to check how much will be the consumption in the following calculation...)
I want to have a calculation, when the real raw material consumption in the calculation is checked and the scale price is match with it.
Do You have any good idea, how to handle?
Br

Dear,
thank You for answering and investigating into this issue, You get a good point, but my setting is actually different form standard:
In my calculation through costing variant and valuation variant - the inforecord has higher priority than the planned price - we only use planned price form mat. master if no relevant inforecord exist, but in my case there are inforecords with scale price.
Issuing production order is not enought for me for checking all costs - some additonal cost components are exist - through overhead determination such as duty, freight, etc. which has been defined using overhead group and overhead key, and assigned to material in material master (costing view).
I know it is a bit more complex than a normal quantity structure calculation - but this is the one, I have to deal with. Available CO-consultant told me, this scale -price handling is MM-issue, that is why I ask MM guys first.
Anyone pls, have some idea about inforecord scale price in cost calculation based on component requirement in actual calculation. I would appreciate a lot.

Delivery cost calculation solution in SRM 7

Dear all,
We have a requirement to capture delivery costs associated purchases made via SRM. We would like to know if itu2019s possible to achieve the two scenarios indicated below. And if so, where and how do we enable delivery cost calculation process for SRM generated POs?
Here are the 2 scenarios/requirements:
Scenario 1.
Shipping costs pre negotiated before a shopping cart is raised. When the PO vendor sends an invoice, shipping costs appear on a separate. We need a functionality to automatically calculate and add/capture these delivery costs to the SRM based PO and have the ability to match/pay for this when the vendor invoices.
Scenario 2.
Delivery costs such as fright costs are not know at the point the SRM PO is created. The PO vendor invoices only for goods that he delivers. Freight costs/charges have to be paid to another vendor - e.g. DHL. We need a functionality to automatically add/capture these Freight costs to the SRM based PO and have the ability to match/pay both the PO and Freight Vendors when they submit their invoices.
Thanks in advance.

Dear Poster,
As no response has been provided to the thread in some time I must assume the issue is resolved, if the question is still valid please create a new thread rephrasing the query and providing as much data as possible to promote response from the community.

MSTP Link cost Calculation

On a trial basis when we migrated from Rapid PVST+ to MSTP in a network of Cisco 3560G switches, we observed that all the link (FastEthernet) cost which by default is 19 have been increased to 200000. Any idea on what basis this link costs is calculated? Do MSTP use some different formula for link cost calculation.
Can anybody suggest any good MSTP migration guide?
Thanks in advance.

Hi! Francois,
Sorry for disturbing you once again. I was simulating the MSTP environment in my Lab ... I observed that whenever I map any new vlan to any existing instance the switch stops all communication in all vlans for few seconds. On debug I observed that all the instances are getting deleted and getting re-created. And by that process all the ports are going into disabled state. Is it becoz .... by adding additional vlan to an instance I am actually creating a separate MST region for this switch alone? But even then I am not able to understand what is the need for deleting all the instances?
I am attaching the log with this message, pls refer to the same.
Will be waiting for your comment.
Anybody else faced similar issue? Any related comments are appreciated.

Actual Cost Calculation in Process Order

Hi All,
I updated Standard cost of a raw material through a cost estimate and also ran cost estimate of the FIN that is using this raw material but when I am creating a Process order, it is taking the cost of this particular raw material from the previous estimate not the recent one to calculate the target cost. Can any body help me with this.
Thanks
MKR

Hi Ashok,
My Valuation variants for the Costing Variant of Cost Estimate and Production order (Actual/Plan) cost calculation are in Sync to get the prices according to the price indicator in material master. But when it calculates cost for a production order, it is picking up cost from the previous period for that particular raw material. I have updated the standard cost by running the cost estimate but still its not working.
Any lead on this. This will be really appreciated.
Thanks
MKR

Target cost calculation in Process Order based on Variance Calculation

Hi all,
I have a question on Target cost calculation in Process Order. My understanding is, the Target Costs gets calculated when the confirmation and GR is made for the Process Order.
But if the confirmation/GR is not done, whether the target costs gets calculated for only the activity types after the Variance Calculation (KKS2).
I have two scenarios. In one, the target costs got calculated for the activity types without the confirmation/GR after the Variance calculation.
In another scenario, the target costs are not getting calculated for the activity types without the confirmation/GR if I try to do the variance calculation in KKS2.
SO i want to know which scenario is correct?
Can anyone answer this question?
Thanks and Regards,
Brijesh

Hi,
In general, the target costs are calculated once you deliver the order.
Target costs for the components and the activities are updated only once you deliver the order and the target cost for the finished product gets updated when you do the variance calculation.
Consider your scenario number 1 - you said the target costs got calculated for activity types without confirmation / GR after variance calculation.
Now, if the order is not having any status like PDLV, DLV or TECO it will not calculate the variances in the first place.
Your second scenario is correct - without GR the system does not calculate any target costs. Also it will not calculate any variances because the order status is still not DLV.

Weighted avg Unit Cost calculation for COGS

Hi friends,
Has any body done weighted avg unit cost calculation for inventory valuation and COGS calculation. In a way we need to mirror ECC material ledger functionality based on the APO data in side the planning tool.
Any ideas on the above!!!
Kind Regards,

Hi Jerry,
Thanks for the tip. I actually needed to clean the spreadsheet up and put bogus values in to comply with company policy. Anyhow, here is a sample of the spreadsheet
http://dl.dropbox.com/u/7499586/junk.png
Just imagine about 100 products and several hundred raw materials, a dozen types of labor and about 30 types of packaging. It's a monster spreadsheet.
The "units" under each product is the number of units per batch. You can see each product has two columns. One where you put in how much of a raw material, package type, and labor type go into each batch, the next calculates the cost for each item. Then it gets summed at the top for the total unit cost for that product.
Let me know if you have any other questions about it. Thanks so much for your help!

How to define routes for freight cost calculation

Hi,
in our company we plan to use LE-TRA Transport with Freight costs calculation. To use Transport it is a must to maintain routes in all sales orders/deliveries. Currently we do not use it and now we have the challenge to define routes and later due to freight costs calculation Stages. There are different solutions for routes. In some other companys we have only routes dependent on the Transit duration, but that's all. They don't use stages and they don't use freight cost calculation in SAP.
As I know routes should describe geographical locations (The way location A till location B). Based on the route we have a defined stage with a distance, shipping type.... That would mean for a company: They need to analyse all delivery channels with different forwarding agents and so on. Is that possible when the forwarding agent is responsible for scheduling? That means for a company with customer around the world thousands of routes?
Alternatively it is possible to create stages in the transport documents. Is that more recommendable? It would be nice, when someone could post his experience with that topic.
Thank you,
Raphael

Hi Luis,
thank you for the response. My problem is not the technical view. I know how to create the routes and what kind of information I need. The problem is to unterstand how this concept can operate in practise in a company with many different customer.
The following site describes the concept of routes in SAP:
http://blog.tkreddy.com/2010/09/17/understanding-the-concept-of-routes-le-shp-in-sap-ecc-6-0/
A company with many delivery plants and customer around the world needs to forward all delivery channels they have to us, A route describes an area and includes stages with location A and B. The stages are assigned to a forwarding agend. Based on that information I can start a freigt cost calculation. The structure of stages and routes also depends on the situation how many different forwarding agents are involved in a delivery process.
In my opinion it is really a big effort to find a reliable solution for the amount of routes and stages. I am thinking about to use the solution to create the stage manually in the transport document and to use the routes to describe the transit time.

Thought I might clarify Jacob's "OSPF calculates the cost this way: Reference . . ." To be more precise, that's how Cisco devices usually compute interface OSPF cost. Other vendor equipment might not auto calculate OSPF interface cost at all, or they might use a different default reference bandwidth.
Also regarding Jacob's suggestion to set reference bandwidth to 100G, that's fine, but be aware that you might lose path costing differences for low bandwidth links. OSPF sums up hop by hop link costs to reach destination. Such a sum can "overflow" if OPSF is summing using a 16 bit counter and sum is greater than 65K.
So, when deciding on changing the auto-cost reference-bandwidth, you may need to consider both maximum and minimum bandwidths on your network, now and perhaps future.
