Min-Max Planning Generating Purchase Requisitions

We have been using min-max planning for a while and scheduling the min-max planning report (planning level: organization) to run every evening to generate a purchase requisition. Of late we have some items that are showing a reorder quantity but not generating a purchase requisition. We have verified the set up of those items against items that are generating a requisition and can't see a difference. What are the possible causes of items not generating a requisition when using min-max planning?
Thank you!

Make sure Item Settup has the "List price" Given.
Source is set to " Supplier"
When you are running the Min-Max Report, it should have the Parameter "ReStock" to "Yes".
Since the records has to come from the Inventory to the Purchasing Module there is possibility that Records might be there in Interface tables. Run the "requisition Import" program and see if it address your issue.
Thanks and regards,

Min Max Planning Error-Unable to generate requisition

when we run min max planning in test instance for certain items we get the the below error:
“Unable to generate requisition”
Checked the source type for the items which had this error.There is no Source type set for those items even then we get this error.Any help.
Thanks

POR generated from Min-Max Planning

Dear Members:
Is there any way, I can distinguish Requisition# generated from Min-Max planning ? I mean technically in po_requisition_headers_all, with help of any flag (column) ?
Thanks.

The requisition header has interface_source_code. For min-max requisitions, it is set to INV.
Hope this answers your question,

Min/Max Internal Orders 1 Requisition

We are running Min/Max planning to replenish stock in an "Emergency Warehouse" organization. The requisition import kicks off internal orders to a replenishment organization. The planner in the replenishment organization would like one order for each Min/Max run. The requisition group-by default in Purchasing parameters is vendor yet we are still seeing one unique requisition for each item thus creating one unique internal sales order per item. Thoughts?

The requisition group-by default in Purchasing parameters is vendor yet we are still seeing one unique requisition for each item thus creating one unique internal sales order per item. Thoughts?In this case the requisitions will not be grouped by Vendor because the supply source is Inventoy which is creating internal requisitions and not purchasing requisition (source is Supplier/ Vendor).
It is important to know how you are importing requisitions and what value is specified for Group By parameter during import. The value you setup in Purchasing Options defaults in the Requisition Import request parameter screen, but this can be changed before submission. So it is possible in your case that requisitions are imported using a different group by than what is specified in Purchasing Options.
From the list of different group by options available (All, Buyer, Category, Item, Supplier) you can probably use 'Location' during requisition import.
Location: Group requisition lines for each delivery location on a separate requisition.
But this will not guarantee 100% success because:
- If you import requisitions with source as INV then those can include requisitions from different INV sources generated from Reorder, Kanban etc having same delivery location. In that case all those requisitions will be grouped under a single header having same location.
- there may be different users running requisition import manually and some may forget to change this group by parameter (defaulted from purchasing options) while importing Min-Max planned requisitions (again they cannot segregate Min-Max, they can just specify INV as source)
A better solution would be to use the oracle provided custom hook (po_reqimp_pkg.post_validate_user_extensions) for requisition import to populate the GROUP_CODE column in PO_REQUISITIONS_INTERFACE table. The logic inside the hook should identify the rows in the interface table generated from each run of Min-Max and populate a unique value for all those rows in the GROUP_CODE column. You need a small piece of code to be added inside the hook.
You can also use REQ_NUMBER_SEGMENT1 column in the interface table to populate an unique value for all rows you want to group together. But in this case the value you specify will become the requisition number if there are no conflicts with the requisition number rule. Both these column, when populated, have precedence over Group by parameter. 1st priority GROUP_CODE (if populated). If GROUP_CODE is not populated then it checks REQ_NUMBER_SEGMENT1. If this is also blank then it uses Group By parameter.

Min-Max Planning concept

Hi Neils,
Can you please throw a light on --> Min-Max Planning Concept and what is the formula for Min-Max
regds
MRR

Hi MRR,
Min-max planning is used to maintain inventory levels for all of your items or selected items. With min-max planning, you specify minimum and maximum inventory levels for your items. When the inventory level for an item (on-hand quantities plus quantities on order) drops below the minimum, Oracle Inventory suggests a new purchase requisition, internal requisition, move order, or job to bring the balance back up to the maximum.
See the Inventory Users Guide > Planning and Replenishment > Min-Max Planning for more detailed description of the principles behind. In addition to Min-Max you may want to consider Reorder Point Planning where you bring demand figures into the calculations.
If you would like to have sales orders or production demands on end-item or sub-assembly levels influence the planning of components then a type of MRP is needed to break down a product structure to lower level material requirements. For even more advanced planning where capacities, constraints and may be even different optimizations objectives are to be considered you have to look at the Advanced Plannning Suite of applications.
Hope this helps ypu in the right direction.

Supply quantity isn't being considered in min-max planning report Oracle

Oracle 12 Issue:
system isn't considering the open PR/PO while suggesting re-order quantity in new PR of same item code. I am giving all parameters with "Yes" except include non-netable parameter with "NO". I take system current date as default date for "Demand & Supply cutoff date".
Please help me to resove/identify this issue.

Hi,
Issue #1:
Need by Date on the purchase order/Requisition line is after the supply cut-off date entered by the user (or defaulted) when launching the Min-max planning report.
Fix: Please re-launch the Min-max planning report with higher supply cut-off date.
Issue #2:
Destination type stamped on the purchase order line / distribution is Expense.
Since it will not affect the on hand quantity for the item, the Min-max planning report is ignoring this purchase order.
Fix:Please retry with a new purchase order with destination type set as Inventory.
Thanks

Reorder Planning vs Min Max planning

Hi,
In what business scenarios should we use:
Reorder planning (ROP)
Min Max Planning?
We are implementing INV/PO for a bank where mostly expense items should be used. Also no manufacturing modules are used.
So which planning will be recommended and why?
Also, if re-order planning is suggested, share the set ups (with screen shots), as to how to set up & get the Requisition qty.
Thanks,

Hi,
Reorder planning is like two bin system. When one bin is empty, the demand is fulfilled from the second bin while the replenishment order is generated for the first one. Reorder Planning uses Oracle Inventory forecasting information to calculate average demand.
In min max planning, we maintain 2 levels, minimum and maximum. When the stock goes below the minimum level, the Requisition is created for the Qty =Max level - Qty already in PO/Req - On Hand.
However, option is available while running min-max to include or not include Qty alrady in PO/Req.
In min-max, the min-max levels have to be maintained manually and the demand forecast is not taken into account.
Hope this answers the question.

Enable billing plan to purchase requisition made in PS

Good afternoon, Mr.
I'm generating purchase requisitions through the Project, and I'm running into a problem:
When generating the purchase requisition SAP is not taking into account the invoicing plan registered with the material component, thereby to generate an appointment request in the amount of the request for the date of need, instead of generating commitments over the time as registered in the billing plan.
How do I activate the billing plan in purchase requisitions generated in the ER, could have programmed the commitment over time.
Att,
André Santos

Hi,
I think you are creating an invoice plan against the activities in a Project, When PR is created against a project system generates commitments, but this invoice will not get copied to PR, as PR is not a legal document, but when we convert this PR to PO we can copy the invoice plan into PO and can have control on this invoice plan as per milestones set in it.
In your post you mentioned billing plan, billing plan will be relavant for SD billing and it will not have any impact on commitments wrt project.
Thank

Min Max planning report - ability to run for specific vendor

Hi,
We have a unique requirement wherein business users would like to run min-max planning report for a specific vendor. Vendor here is item sourcing vendor. We are on R12 12.0.4. This version of applications doesnot support sourcing vendor as the min-max report parameter.
Other than setting up item category for ASL vendor, i can't think of any other easy way to accomplish above requirement. Please suggest workaround for above requirement.
Thank you

If you have to do this, here is a complex workaround.
Create a request set that contains a custom program as first stage and the regular min-max as the second stage.
The custom program accepts vendor name as a parameter and disables min-max planning flag for all items EXCEPT those that are sourced from that vendor.
Then the 2nd stage runs and creates requisition.
You may add a 3rd stage that resets the min-max planning flag.
Make this program incompatible with itself so 2 users won't run it at the same time.
Hope this helps,
Sandeep Gandhi

Min Max Planning not reading Flow Schedules as Demand

We use min max planning to order all recurring purchases and flow schedules for production planning.
Min max planning report does NOT see flow schedules as a source of demand. Is this correct or are we missing a setup somewhere?
If min max planning cannot read flow schedules, is there a standard report to identify component shortages where items are between min max level but not enough on hand to fulfill the open flow schedule?

Check the user and employee tht you have used to launch the conc prog...

Min Max Planning Report

Dear all,
In the exported report that Store use as a reference in raising PR (Min Max Planning - under Planning module) there is a column called “Supply Quantity” .. just want to know where from the data on this column is coming from?!!
Thanks ..

Hi,
Supply quantity comes from various sources of supply (e.g. Open Purchase Orders).

SNP Heuristics generates purchase requisition

Hi Experts,
I have a requriement to generates purchase requisitions start date at Monday; Im trying to use period factor but still I gets the reqs still falls in different days and also the planning calendar under the lot-size. Is there any other ways that I can apply this requirement?
My lot-size is weekly bucket and 1 day transportation duration and 1 day GR.
Thanks
Regards,
Lhon

Thanks again for your reply; yes some of the days that didnt fall has holidays for that current week thats why it didnt schedule at the desired date but some of the Preqs generated were fall on other days even without any holidays in the calendar. Except for the calendars of the transport and handling what are the other factors thatc an affect this specified period factor settings? Other than this setting would you consider any other scenario to apply this requirement?

ESYU: Min-Max planning을 실행하면 자동으로 ReqImport program이 launch 되지 않는 원인

Purpose
Oracle Inventory Management - Version: 10.7 to 11.5.10
REPORT:INVISMMX - Min-max planning report
EXECUTABLE:POCIRM - Requisition Import
Buy items에 대해 Min-Max(with Restock=Y)을 실행하면, 이 program은 ReqImport를
자동으로 launch 시키지 못하고 단지 po_requisitions_interface_all table에 data를
insert 한다.
하지만 사용자는 Min-Max가 실행되면 이후 자동으로 ReqImport가 실행되길 원하고
있다. 이를 위한 workaround 방법을 소개한다.
Cause
ReqImport가 Min-Max 이후 자동으로 실행되는건지, Min-Max에 의해 자동으로 실행되는지
구분할 필요가 있다.
ReqImport는 Min-Max에 의해 실행되지 않는다.
Min-Max의 standard design은 단지 po_requisitions_interface_all table에 data를 넣어
주기만 할 뿐이지 ReqImport request를 자동으로 실행시키지는 않는다.
ReqImport는 Min-Max 진행 후 실행될 수 있다.
왜냐하면 ReqImport는 주기적으로 실행되게 scheudling 되어 있거나, ADS_PO_REQ_IMPORT_TRG1
와 같은 trigger에 의해 실행된다.
일부 vision demo instances에서 위 trigger를 볼 수 있는데 이 trigger에 의해 po_requisitions_interface_all
table에 data가 insert가 되면 ReqImport가 launch 된다.
Note: 이 Trigger는 standard product이 아니므로 귀사의 instance에서는 찾을 수 없을 것이다.
Solution
1. Short-to-medium term solution at your instance:
1-1) ReqImport가 주기적으로 실행될 수 있게 Schedule 해 놓는다.
-- or --
1-2) Min-Max report(Restock=Yes) 실행 후 manual 하게 ReqImport를 실행한다.
-- or --
1-3) Min-Max와 ReqImport programs을 포함하는 Report Set을 define 하고, Min-Max 대신
이 Report set 만을 실행한다.
-- or --
1-4) po_requistions_interface_all table에 triggers(similar to ADS_PO_REQ_IMPORT_TRG1)를
생성한다.
2. Medium-to-long term solution from Oracle
ER/Doc bug을 등록하고 metalink를 통해 진행과정을 check 한다.
2-1) Enhancement Request via ER/Bug 4310485 to have Min-Max Report to fire ReqImport automatically.
2-2) Documentation Bug 4310487 to have the INV User Guide corrected that Min-Max does NOT create Requisitions,
but ONLY populates the po_requisitions_interface_all table.

Need some help with the DOF Min Max Planning Logic

Hello All,
Morning...could someone please help us with this issue which we are facing in our production system.
We are running the Dof Min Max Planning Report at the Subinventory level and for a given item.
This item setup in this sub inventory has the Min qty : 2 , Max qty :2.
--We don't see any open orders/ requisitions in the system for this item.
--We also don't see any expected receipts for this item coming to this org/subinventory.. All the shipment lines are in Fully Received status.
--We dont see any stuck supply records in mtl_supply table as well..and also checked for the Inv Transactions interface tables as well ( MTI , mtl_material_transactions_temp)..we dont find any stuck transactions for this item, subinventory & org.
Now when we are running the Dof Min Max report is is showing the Supply Quantity as 2 and Available Quantity as 2.
Hence the Reorder quantity is coming as Zero..basically it is not re stocking the item again for this subinventory level.
Could someone please assist as to what could be reason why this Supply Quantity is showing some value when we dont see any stuck supply / expected open receipts..
What else we need to check here to get this issue resolved and to know the source of the Supply Quantity.
thanks

In the report run, what parameters are considered as Supply?, Also did you check the supply data considering your cutoff dates offset?, the item what you are talking about is a buy item? check if there were requisitions already created.

Min-Max Not Generating Req

Hi,
New Created Item...when running min-max planning..is not raising req..
Does not have on-hand..has min and max values in general planning..source is set to supplier.
Sourcing rule has been defined and added to assignment set
All the attributes at master and org level are same
Please Advise
Thanks

After running min max, have you run reqimport program?Now i can see them..but i thought req import gets auto kicked off..when we select re stock to yes and for repetitive item is set to create requisition...
is this the standard way..we manually have to run req import?
