Configure lot size for MRP

Hi Experts,
I would like to configure lot size for 3 monthly, can any one explain me the configuration procedures?
Thanks alot
Rgds,

Hi Vivek,
I copied the Z3 form MB, and changed the no of periods into 3. and there're no difference between material assigned with Z3 or MB.
We haven't activated MRP4 view, do I have to activate that view first to make this happen?
for your additional info, I use MRP type (configured) based on ROP.
Pls help.
Thanks

Default lot size for MRP type

Hi,
Can we set default Lot size for MRP type ?
Regards
Karthik

Dear,
Yes you can do it by creating material master with MRP Pofile.
First you need to create MRP Pofile in MMD1 where you need to define the LOT SIZE and MRP TYPE which you want then make these value as Fix Value.
Then Create material master MM01 with this MRP Profile and check your result.

Hello Vikas,
I am not too sure ? Can you not change the field ? It doesnot need any cofiguration on the MRP view level. The value needs to be set

Is it possible to change the costing lot size for the preference calculation?
Reason for my question is: We have all prices on price unit 100
and we want to use also the price unit 100 for preference calcalation.

Lot size procedure & MRP

Dear All,
What is Lot size procedure and how it will affect during MRP run?
Please provide some example against explanation.

Suppose,
Avaialble Stock= 50
PIR 150 on 25/06
PIR 60 on 27/06
When you run MRP,
                             Avaialble stock
PIR 150 on 25/06       100
Planned ordre 100       0
PIR 60 on 27/06         60
Planned order 60        0
For 1st PIR, The NEt requirement is 50-150=-100, So planned order for 100 is created.
For 2 nd PIR, the ner requirement is 50-150-60+100= -60, planned order for 60 is created.
In toto, net requirement = Stock-total requiremens+ Total receipts

EX lot size for maximum value

Hi Could someone answer this, my minimum lot size is 100 and max is 500, when my PIR qty is 90 it will generate planned order for 100 where as when my PIR is 600, i am expecting the planned order qty for 500 but it always the same with minimum lot size, is there any specific reason? using mrp type PD.

Hi Sprint,
Well you have to go through with the lot size procedures OK. EX means lot for lot order quantity so it does not consider the MINIMUM lot size OK please check once again OK.
If you are order quantity is 600 and maximum lot size is 500 then after running the MRP go to MD04 screen you can see there planned orders will be created so there first it will create Planned order for 500 quantity and then there will be another planned order for 100 please check once OK.
It will consider only maximum lot size OK.

Lot Size for Split Cost

Hello,
My company has just had SAP installed and I am trying to confirm whether there is a general calculation in SAP or whether it is due to the configuration that has been choosen from our implementor.
I have costed some materials we have setup as a split cost (choice of either purchased or manufactured) and setup the mixing ratio. I then cost it but SAP generates the Lot size automatically and this can not be changed.
i.e. 90%:10% split gives a lot size of 280 (252 and 28) and 50%:50% split gives a lot size of 200 (100 and 100).
Please can you confirm that this is normal and also if it can be overriden?
Thank you for your assistance

Hi,
This is a normal behaviour of the system.

Incoming message size exceeds the configured maximum size for protocol t3

Hi All,
I've encountered an error as follow:
weblogic.socket.MaxMessageSizeExceededException: Incoming message of size 50004000 bytes exceeds the configured maximum of 50000000 bytes of protocol t3.
But the request message is only 3MB, why it is enlarged to over 50M?
There is a For Each loop section in main flow, is it because for one loop, there will be a copy of request message?
How to enlarge message size for protocol t3?
Go to server/protocol and change 'Maximum Message Size' for AdminServer, OSB Servers and SOA servers?
Thanks and Regards,
Bruce

Hi,
1) After setting -Dweblogic.MaxMessageSize to 25000000
<BEA-000403> <IOException occurred on socket: Socket[addr=ac-sync-webserver1/172.24.128.8,port=9040,localport=36285]
weblogic.socket.MaxMessageSizeExceededException: Incoming message of size: '25002240' bytes exceeds the configured maximum of: '25000000' bytes for protocol: 't3'
at weblogic.socket.BaseAbstractMuxableSocket.incrementBufferOffset(BaseAbstractMuxableSocket.java:174)
2) After setting -Dweblogic.MaxMessageSize to 50000000
<BEA-000403> <IOException occurred on socket: Socket[addr=ac-sync-webserver2/172.24.128.9,port=9040,localport=59925]
weblogic.socket.MaxMessageSizeExceededException: Incoming message of size: '50000400' bytes exceeds the configured maximum of: '50000000' bytes for protocol:
't3'.
And even after setting various values for -Dweblogic.MaxMessageSize , issue weblogic.socket.MaxMessageSizeExceededException was observed.
To overcome the issue set Manual Service Migration Only as after several experiments and replicating the issue it was found out that in case of no available pinned services, must set the migration policies of the migratable targets on "Manual Service Migration Only".
And once it is corrected; it was noticed that weblogic.socket.MaxMessageSizeExceededException issue also resolved.
WebLogic Server can fail over most services transparently, but it's unable to do the same when dealing with pinned services.
Pinned Services : JMS and JTA are considered as pinned services. They're hosted on individual members of a cluster and not on all server instances.
You can have high availability only if the cluster can ensure that these pinned services are always running somewhere in the cluster.
When a WebLogic Server instance hosting these critical pinned services fails, WebLogic Server can't support their continuous availability and uses migration instead of failover to ensure that they are always available.

Configuring Packet size for IDOCS on outbound Side

Folks,
Can we configure the packet size for idocs on the onutbound side of the Adapter ?
Manish

Hi Manish,
It is posible if all 1000 idocs are of same Idoc type.
Jus go and change the occurene of Idoc in the XSD as 1..Unbounded. SO that your the message can hold multiple Idocs.
But let me clarify here, if you send 1000 idocs from R3 , it will come to XI as one-by-one. There is no mechanism to get 1000 idocs at a time. So you need to collec all the idocs and then send it.
Just have quick look into this

Lot Size Planning for Procurement

Hi guys
In our company we work with minimum lot sizes for procurement, and we need to configure minimum lot sizes for procurement in the SNP optimization run. It´s posible to do it in SNP, pls can someone tell me how to configure this in SNP?
David

Hi David,
I am glad to hear that.
Regarding your performance issue: it is very usual to have long runtime when using discrete model.
The complexity of this model is much higher than a linear problem; so the optimiser takes time to find THE optimal solution.
However there is a lot you can do to make it better:
1. Split your model: instead of running 1 big optimiser, run serveral smaller one in parallel.Ensure your model are all independant (e.g. no common product or resource)
2. Use decomposition: (product/ time/resource; based on your scenari) to simplify the porblem, hence speeding the solution.
3. Set a maximum time
You do not have to wait for THE optimal solution. The optimiser can sometime very quickly find a very good solution; the last hours are spent "fine tuning" it. Potentially, you might not be able to see the difference between a 4h job and the 15H one).
Hence SAP advises to set a maximum runtime when working with discrete model.
The question is how to define this maximum time to optimise the ratio solution quality / runtime.
Answer: test it, check the result. Be aware that perfomrance testing for the optimiser can take a while.
4. fine tune you optimiser setting
There is a couple a finetuning that can be done to improve performance, especially for discrete model.
I will not be able to help you woth that.
As far as I am aware only the SAP optimiser team has the expertise to help here.
I strongly recommand to contact them; their help is often invaluable. They will also help you to define the 3 first points.
I hope this will help you.
Thanks and Regards

Lot size calculation for Purchase order

Hi all,

Hi,
You can done it with change Material Master.
Enter MM02 t-code, enter your material code and select MRP1 view.
Here maintain Rounding value as 100 in material master.
After when your create purchase order system put quantity as 100, 200, 300 etc.

Min max lot size time based for use with SNP and PPDS

Hi all, Is there anyway to set up time based min and max lot sizes? ie we want to have a Max lot size which is small for use with the first 3 months of our plan which starts life in SNP and then converts to PPDS and into blocks for block planning, but months 4 to 36 we want to leave as large max lot sizes as there is no need to have the small max lot sizes for the different horizon.
As far as I can see there is only a material/plant lot size and Max lot size and no way to have a different setting in a different time period.
Thanks
j

Hi John,
As you know, in the product master, the lot size maintenance is time-independent, so that obviously can not be used for your scenario. As per my understanding, to meet this using standard functionality, you can maintain multiple product specific t-lanes (for STRs) and PDSs (planned orders) with required lot size ranges and validity dates (for short or long term horizon). But, again since the validity of t-lanes and PDSs will not be automatically rolling forward so the updating the validities will be a challenge.
The other option could be to enhance the heuristic functionality at lot size selection step while creating order.

Umesh

Lot size

The parents material lot size is fixed lot size , child component lot size is 2 week lot size. ( ie. 2 week = 10 Days ).
question:
If the demand for parent material in month,after MRP run the dependent requirement for child component also getting generate only one planned order.
What are the possibilities if the parent demand in month, child requirement is needed in weekly basis .Any chance to get the child requirement in weekly by changing lot size or any other possibilities.

Hi,
Thanks for your answer. if we change the lot size for dependent material to weekly , biweekly or fixed etc....
The dependent req. will generate according to the lot size that is absolutely correct. but planned order or purchase req. will create according to the parent demand (ie .Adding of dependant req. what ever falling with in the lot size period and for that quantity planned order or purchase req. is getting created )
Actually my requirement is for the each dependent requirement one planned order should get generate .

Lot Size "WB - Weekly Lot Size"

Why is this system is not throwing correctky the requirment on every MOnday.

Please read SAP online help:
http://help.sap.com/erp2005_ehp_04/helpdata/EN/f4/7d282c44af11d182b40000e829fbfe/frameset.htm
Please check your settings in SPRO:
SPRO > Production > MRP > Planning > Lot-Size Calculation > Check Lot-Sizing Procedure
...here you can check "Scheduling" field (V439A-TERBV) of lot size "WB". And you can check also field V439A-LGTER.
F1 help for the field:
Scheduling for period lot sizes in short-term area
This indicator defines the time in the period the system is to create the availability date or the start date for the lot for period lot-sizing procedures.
The availability date is the date on which the material, including the goods receipt processing time, is available again. In the MRP list, the availability date is equal to the MRP date.
In in-house production, the start date is the order start date, in external procurement the start date is the release date.
The following procedures exist:
Availability date equal to requirement date
Availability date at period start
Availability date at period end
Start date at period start
Planned order start date at period start and availability date at period end
With this setting, the in-house processing time in the material master record is ignored.
Note
The following is valid in all cases:
If the start date lies in the past, the system switches to forward scheduling. The following example illustrates how the system procedes:
The period start is Monday and the period end is Friday. The planned delivery time is 8 days. The indicator for determining the date is set to, "availability date at period end".
Today is Monday, a requirement is planned on Wednesday. The system has to schedule forwards. As the system works using date determination, today's date is not selected as the start date. Instead, the system determines the next period end, and uses backward scheduling to calculate a start date that does not lie in the past. This means that the end date was planned for the Friday of next Week.
