MRP Process Bottom-Up scenario

Hi !
I have some specific requirement which given below
1. Bottom Up Planning. I have two material A & B as HALB. Based on the capacity and availability of other ROH how much I can produce A & B is planned. Accordingly various FG is planned. This process is done yearly (Budget) and continue full year as 3 month rolling plan. End of every month following month is firm and other two data collect from budget and a tentative for production but check the ROHs availability. Suggestion on this scenario is required.
2. In the above scenario I have 4 different plants for different FG. During production they collect ROH from their storage location. I have a separate plant where initial stock is posted and transferred to different production plants. My requirement is after planning run collective requirements for the ROHs will generate at my purchase plant and also I have the tracking how much is required for which production plant.
Suggestion for the process as well as configuration is required.
Thanks & regards

Hi!
The main problem is Halb Vs. FG planning. E.G A Halb is palnned as per the capacity and various parameters. When FGs will plan they check the plan of A because A is my critical item and production qty cannot be more than this.
Now when I plan for my FGs they check how much of A is required to produce the FG quantites and final plan will freeze when requirement of A from various FGs and the plan of A will equal.
Thanks

Hi ,
Yes, it is on the same server.
I have used the below mentioned parameters to rename the files
At Primary Pfile:
*.db_file_name_convert=('D:\app\oracle\oradata\test\test\','D:\app\oracle\testdr\oradata\datafiles\')
*.log_file_name_convert=('D:\app\oracle\oradata\test\test\','D:\app\oracle\testdr\oradata\redologs\')
At Standby:
*.db_file_name_convert=('D:\app\oracle\testdr\oradata\datafiles\','D:\app\oracle\oradata\test\test\')
*.log_file_name_convert=('D:\app\oracle\testdr\oradata\redologs\','D:\app\oracle\oradata\test\test\')
But the output of v$datafile at standby is showing the path of Primary datafiles
I manually tried recovering them but it is prompting me the same error.

Could Not Plan MRP Process Planning.

Hi, all members of the forum. I Have a problem with MRP process from OPM Process Planning, Because it don´t make suggestion plan. I have already OPM Process Planning setup, I don´t have sales orders just forecast and associate it with the correct schedule, the schedule parameters are ok, Formulas have a effective dates, Recipe have a effectivity dates and validity rules. Besides already setup Warehouse, production and transfer rules, and items Plant-Warehouse relationship. When I run MRP, it doesn't show me any error message, in MRP
Material activity inquiry it only shows me the demand but not the supply and in the Action Messages inquiry shows me the action messages type: SHRT (Inventory Shortage) and in the message text indicate: Could Not Plan; Consequently I cannot manage any plan. Some of you could help me with this problem.
Thanks in advanced
RGVela

Hi
My suggestion is to check the lead times and to check the setup of Plant warehouse relationships. This normally is an issue with setups. This message come normally for any setup issue
Sorry, but at the moment I dont think I can anything more.....

Consignment process in Classic scenario

HI Experts,
can anyone let me know whether we can use consignment process in classic scenario.
we are having SRM 5.0
If it is possible kindly let me know what needs to be done in SRM to set up the same
regards
subbu

Hi Subbhu
Azad is correct.
but you can see this thread but doing enhancement you might achieved .but before comitting to customer you have to do lot of business analysis /business impactsand etc.
See Yorum thread. you must get an idea.
STO classic scenario SRM 4.0
BBP_CREATE_BE_PO_NEW badi helps
you need to change the item category /document type must have consignment
Consignment is items procured on a consignment basis.
Material number is necessary
Account assignments cannot be made for material ordered on consignment.
Goods Receipt is necessary
Invoice receipt not necessary
Consignment stocks are managed separately and are not valuated

Setting up MRP in multiple plant scenario

Hi,
We are planning to implement MRP in our system. I understand that MRP is normally carried out at a plant level. However, since we have multiple plants (from which we ship our products), we want to be able to run MRP across multiple plants. To elaborate, we want to have one forecast figure for all the plants (basically forecast at material level, NOT by plant), consider inventory across all the plants, and then based on that, we want to be able to generate PRs/POs. It would be ok to create POs with one default plant and if needed, change later the receving plant on the POs manually based on the inventory situation in each plant. Of course, we need to tie in the demand situation (customer orders) in each plant in the MRP process.
Is there a way to do this using standard SAP or with some amount of customization?
Any insight/ideas would be greatly appreciated and help us move in the right direction.
Thanks,
Prayarna

Total Planning
Use
Total planning covers the planning of all the materials that are relevant for requirements planning and includes the BOM explosion for materials with a bill of material.
You can use total planning for a single plant or you can use the scope of planning to control whether the total planning run is executed on a multi-plant level
for several plants
for one MRP area
for several MRP areas
for a combination of plants and MRP areas.
Prerequisites
Only for multi-plant planning with scope of planning:
You have grouped together the plants or alternatively the MRP areas, which are to be planned together, in Customizing for MRP in the IMG activity Define scope of planning for total planning.
In Customizing for MRP, you have made the necessary settings for Parallel processing in the IMG activity Define parallel processing in MRP.
Features
Defining the Scope of Planning
You can define different scope of planning groups in Customizing.
You specify the sequence of the individual MRP units (plants or MRP areas) for each scope of planning by entering a counter. This counter defines the sequence in which the MRP units are to be planned.
You can enter as many plants as you like in the scope of planning.
If you have activated material requirements planning with MRP areas, the entry of a plant thus includes all the MRP areas of this plant. During the planning run, the MRP areas of a plant are always planned in the following sequence: plant MRP area, storage location MRP area, subcontractor MRP area.
You can, however, also enter one or several MRP areas in the scope of planning and thus restrict the total planning run to these MRP areas.

What are the disadvantages of implementing APO- Demand Planning without improvements or cleaning up the MRP. in other words is DP implementation dependant on MRP process. Gurus please advise

HI All. What are the disadvantages of implementing APO- Demand Planning without improvements or cleaning up the MRP. in other words is DP implementation dependant on MRP process. Gurus please advise

Hi Amol,
DP is the demand planning machine, here you estimate your forecast (future sales).
The MRP is a supply planning machine, here you use estimate the replenishment.
Both machines in a technical perspective are independent one each other. Now in a business perspective they are not: The problem that you will have if you don´t clean your MRP elements is not a problem in DP itself. I mean, you can have a very success implementation in DP, your forecast accuracy will be very good.. and you will get a very good forecast, but when the MRP run and estimate the replenishment, the effort that you made in DP will not be translated in good results and your planning situation will be still not good.
Kind Regards,
Mariano

Stateful message processing for async scenario

Dear all,
my async scenarios:
1. RFC -> PI -> File
2. File -> PI -> RFC
Following facts:
- The second message is a response to the first one. Both message are separted and async.
- Scenario 2 can be send some hours after Scenario1.
- A response should only be send if a specified field in the message of first scenario is filled.
For example: Message in scenario has a field <ResponseNeeded>YES</ResponseNeeded>
This field does only exist in message of scenario 1.
- Both message have an ID field (e.g. <ID>4711</ID>) which can be used to identified the
corresponding message.
Questions:
- Is it possible to use stateful message processing for this scenario? Or do I need BMP + Correlation?
- A service interface with pattern "stateful" can only be used synchronously. So is it
possible to use this stateful for async message processing at least?
I would assume that I will need a BPM that sends the messsage and keep alive until a
response will be sends with same ID. After this I would check message of scenario1 and
send (or even not) the message of scenario2 to receiver depending on <ResponseNeeded>.
Thanks in advanced.
Chris

Hi Chris,
Although BPM is possible here, I would not recommend you to use one here for the reason,
>>Scenario 2 can be send some hours after Scenario1.
This means you are keeping a process alive for so long which is not a good thing to do.
You could end up with a lot of open/live process instances.
Having said that, if you still wish to go ahead with BPM, the steps would be
1. Receive async (RFC req) - start process, correlation based on ID.
2. Switch step (Evaluate ResponseNeeded)
branch 1(True): a. Send asynch step - File
b. Receive async - File correlation - ID.
c. Send async - RFC call.
branch 2(false) a. Send async -File
3. Stop process.

How do you differentiate business process and business scenario

how do you differentiate business process and business scenario???
pls help

Google says;
A business scenario is a description of a business problem, which enables requirements to be viewed in relation to one another in the context of the overall problem. Without such a description to serve as context, the business value of solving the problem is unclear; the relevance of potential solutions is unclear and there is a danger of the solution being based on an inadequate set of requirements. A key factor in the success of any other major project is the extent to which it is linked to business requirements, and demonstrably supporting and enabling the enterprise to achieve its business objectives. Business scenarios are an important technique to help identify and understand business needs.

Physical standby failed to start MRP process

Hi,
I have a qa db which is in ASM. I have a qa standby which is a physical standby also in ASM. I added space to the primary. Unfortunately, the standby diskgroup did not have enough space and standby mrp process crashed. I edited the primary data files to release some space and tried to restart the standby but it does not seem to work.
What next?

Er, Can you provide more information?
Like maybe some details from the alert logs?
Or maybe even the error message you get when you try to restart the standby
The more information the easier it is to debug at a distance.

Scrap calculation on MRP process

Dear all,
I have a requirement from a customer which is the following:
They are using the functionality "scrap component calculation" (PP). They would like to change the scrap percentage (the one from material master data) taking the information from a sales order when the MRP process is running.
Do you know if there is any user exit available at that time?
Thank you very much for your information.
Ines Simes

Hello Ines,
I once have debugged the MRP under 4.6C to find a user exit where I could modify the result tables (for each plant, by material and such), but I haven't found /any/.
Since there was a serious problem to correct, we had to modify the MRP. There's a top-Level-Loop that breaks down the BOM where's a good place to start with.
Best wishes,
Florin

MRP Process Execution

Hi,
Please guide me about the following query please:
Does MRP Process consideres the Purchase Requisitions and Purchase Orders in which items (Material Codes) are marked as deleted?
If yes, then please guide me how can i exclude these PRs and POs from the scope of MRP execution for the Materials got used in the PRs and POs.
Thanks and Regards

Hi,
Thanks for your reply please.
But my question is that the Materials are not deleted but their reference in the PRs and POs are deleted i.e. the PR line or PO line in PRs and POs are deleted but still is it possible that MRP considers these Material lines of PRs and POs?
Please guide.
Thanks and Regards

SAP HANA as accelerator (secondary DB) for MRP process

Hellow all.
Can we use SAP HANA as accelerator (secondary DB) for MRP process? Or HANA for MRP usefull only as primary Database?
We can't opportunity to change our curent DB, but want to improve speed of MRP.

To my understanding, MRP on HANA is available only as primary db and not in side car scenario

Help scope out MRP process

We are kicking off an MRP project in a couple months and I need some help filling in a few gaps in my knowledge. I am fairly familiar with MM but hardly at all with PP. We are on ECC 6.0. Not running SRM/APO.
Some background: My company wishes to do forecast based MRP. We have about 2 years of MM transactional history and inventory of data. We have not implemented any PP but are prepared to put in whichever components are required in support of the MRP process. However, a non-SAP system will remain our production order system. We use SAP MM/WM for procure to pay and IM of raw materials. The desire is to marry SAP's generated forecast based on historical data with a future sales/demand forecast created in Excel. This sales forecast lists out the finished good. The forecast gets generated quarterly for the next 3 months.
A few questions I had:
1) Since we do not care to valuate or inventory the finished good, I assume that we need to represent the finished good as a phantom material with the BOM components being the raw materials?
2) What is the BADI that is used to import the Excel sales forecast? What transaction calls the BADI?
3) I assume that after SAP marries the historical and future forecast data, there is the ability to view the consolidated forecast and make adjustments...what transaction is used for this?
4) We have three plants and so far each plant has been carrying out its MRP planning (outside of SAP) on its own. However, there are many raw materials and finished goods that are common to the plants (ie same SAP material numbers) and, if not already, could be sourced from the same vendor for better pricing. On occasion, when there is a shortage in one plant we do a plant-to-plant transfer.
a) I assume there is the capability to run MRP using the summarized forecast of all three plants? I'd group the plants under an MRP area, correct?
b) Can some raw materials be planned at the plant level while other materials at the global level?
c) Or if MRP takes place at the plant level, is there any functionality for our global procurement team to see a more summarized global view of the material requirements? He'd need this, for example, to negotiate better pricing on centrally agreed contracts with the vendor.
Thanks!
Vlad

Vlad,
1) Since we do not care to valuate or inventory the finished good, I assume that we need to represent the finished good as a phantom material with the BOM components being the raw materials?
Don't know where you got that idea. I wouldn't do that, but I don't know all the particulars. If you intend to sell finished goods, you probably will want to put them in a plant as stock. If you intend to build finished goods, you probably shouldn't use a phantom.
3) I assume that after SAP marries the historical and future forecast data, there is the ability to view the consolidated forecast and make adjustments...what transaction is used for this?
Big assumption. There are several ways to approach forecasting within SAP ECC. These functionalities are not a 'transaction'. I suggest you look at standard online help to get a feel of what is and is not possible. Below is a bit of info about forecasting within SOP. SOP is one of the planning methods with the greatest feature sets. If SOP doesn't have enough functionality for you, then you probably need APO. There are also simpler methods of forecasting in SAP.
http://help.sap.com/saphelp_erp60_sp/helpdata/en/a5/63201843a211d189410000e829fbbd/frameset.htm
4) We have three plants and so far each plant has been carrying out its MRP planning (outside of SAP) on its own. However, there are many raw materials and finished goods that are common to the plants (i.e. same SAP material numbers) and, if not already, could be sourced from the same vendor for better pricing. On occasion, when there is a shortage in one plant we do a plant-to-plant transfer.
a) I assume there is the capability to run MRP using the summarized forecast of all three plants? I'd group the plants under an MRP area, correct?
another big assumption. MRP, unlike forecasting, is generally done at the plant level. There are ways to manage MRP so as to consolidate your demand into a single plant, but ultimately the purchased materials will have to be sent to the place where they are needed. If you have 5 places where your RM is needed, you will either cut 5 POs, or one PO and then ship the parts internally to the point of use.
b) Can some raw materials be planned at the plant level while other materials at the global level?
Generally MRP planning parameters are set at the plant level. There are, however, ways to manage your requirement.
c) Or if MRP takes place at the plant level, is there any functionality for our global procurement team to see a more summarized global view of the material requirements?
Yes
In closing, expert Mario Adler has given you some sound advice. What you are describing is a project. Some companies take months or years to implement a solution similar to the one you are describing. If you want to get the best bang for your buck, engage a consulting company who has done this before. You will end up richer in the end.
