MRP Net Required/Available Qty

Hello Gurus ,
I am carrying out MRP at plant level .After that MD04 We are analysing the result .We are developing Z report where we need to show Net Required Quanity(-) or Avaialable Quanity .We are using MDKP/MDTB table .
1.Material Requirement Planning No xxxxxxx is not getting updated in MDTB table .I am getting MRP Table no from MDKP using Plant /Material Combination .
2.What is the SAP Table -Filed name to retrive Net Required/Available Quatity (Planned quantity on the time axis that results from comparing receipts, issues, and current warehouse stock)
Thanks and regards

MRP Net Requirements Calculation

Hi Guys:
I defined a Planning Horizon of 40 days, for Example if today is the start date Since Planning horizon is 40 days (01/30/2012).
Vendor Lead time = 2months
Purchase order to vendor with Delivery Date (12/20/2011) : 5000 Pc
Purchase order to vendor with Delivery date ( 03/04/2012): 6000Pc
Onhand Inventory = Zero
So i have Sales order for 10000 with Delivery Date ( 12/28/12) with in the Planning horizon.So when I run MRP using MD02 ,
Does the system consider Purchase orders with delivery dates that are outside planning horizon into the net requirements calculation?
thanks for the help.

dear friend,
as far as i know the available stock is calculated as follows:
plant stock
safety stock
+
receipts (pur.orders, prod. ordersfirmed proc. proposals)
requirements quantity (say, PIRs, mat. reservations,...)
=
available stock
shortage occurs if available stock is negative, that is, the requirement quantities are greater than expected receipts and stock quantity.
so, system specifies the date of the issue (for example, customer requirement, planned independent requirement, reservation, forecast requirement) as the requirements date.

Exclude Stock Transfer from MRP Net Requirements

Hi,
Is it possible to exclude the Stock Transfer Orders from the Net Requirements generated by MRP? I want to base the requirements only from historical consumption. In my Stock/requirements list (MD04) for example, the Requisition generated by MRP increases in quantity since there are open Stock Transfers which are to be served by that plant to other plants.
Regards,
Lee

Nazrin,
Availability check configuration (OVZ9) has no impact on MRP. MRP relies on its internal rules when it is performing its net requirements calculation. You have very little control over which elements are included/excluded.
You can exclude selected storage locations from MRP planning. Stock and reservations against these storage locations will therefore also be excluded.
You can exclude a material from planning, change the material master MRP type to ND.
Your best bet, though, would be to set your PM planning process up such that these materials never create the reservation in the first place.

MRP net requirement calcualtion for Lot sizes

Hi all ,
Can some one help me on this ..
I want to set up the MRP for the Raw materials Procurement .
for this i want use MRP type as PD and lot size as WB Weekly lot size .
but as per the requirement the MRP is run daily , i need clarification on certain things such as how does the system calculates the weekly lot size ? say if the requirement is converted into PR on the first day of the MRP run ,followed by that if the requirement varies does the system creates a new PR or it changes the Qty in the existing PR if its was not converted to PO .
what are the stock types considered during PR creation and how are the delivery dates determined during the PR creation ?
thanks ,
ksr

Hi Chris
You can try to set up a maximum lot size and a takt time on the material master.
Take a look on the F1 help of this field on the material master:
Takt time
If a requirement quantity (for example, for capacity reasons) cannot be procured in a single lot, you have to schedule several receipts. In conjunction with the overlap indicator in the lot size (set in Customizing for the lot size), you can use the takt time to specify that these receipts are offset, that is, that they are delayed by the takt time.
You enter the takt time in workdays.
Use
The system uses the takt time if a requirement is covered by several receipt elements due to restrictions on lot size such as maximum lot size (with all lot-sizing procedures) or rounding value (with fixed lot size with splitting).

MRP Net Requirements calculation in External procurement Vs STO

Hi gurus,
Lets say I have a FG 1234 which has raw component 9999.
Case1:
Setting for 9999 is externally procured.
I have a stock of 50 pc for 9999.
I got order for 60 pc for FG 1234.
so system will only create purchase reks for 10 pc of 9999 as it already sees 50 pc in stock.
Case 2:
Setting for 9999 is externally procured but from one of our own plant (Using SPK 40)
I have a stock of 50 pc for 9999.
I got order for 60 pc for FG 1234.
will system create STR for 10 pc of 9999 as it already sees 50 pc in stock? or will it create STR for 60 pc without checking stock in the ordering plant?

>
dorian661 wrote:
SPK 70 will not create an STR. Stock of 9999 will be checked in supplying plant. In case there is a shortage, a procurement proposal will be created against the dependent requirement here. Stock is not checked in ordering plant. You will notice that dependent requirements for 9999 will be seen in the supplying plant.
Dorian,
Thanks for the reply. so are you saying that in SPK70
In ordering plant - MRP will not look at the stock situation for that material
In supplying plant - system will check stock requirement and create dependent requirement for the shortage amount
and in spk70 case, against what element is the delivery done to the ordering plant? in spk40 delivery is done against STO.
Thx

Net requirement calculation in MRP

Hi Gurus,
Is there any way we can exclude Created Purchase order ( Not yet released ) in MRP run for the Net req calcualtion . ( pl suggest other than exit )
Regards,
Prasanna

Hi prasana
Net requirement calculation in MPR will include firmed receipts. ( P.O.). You can only block what are all given in plant parameter.
We can exclude in Availability Check, in scope of Availability check setting.

Net requirement calculation

Dear Gurus
In Net requirements calculation, Safety Stock, Recipts (Purchase Orders, Production Orders, Firmed Procurement Proposals), Requirement qty(Pir, Customer requirements, Material reservations) are considerd
In My Situvation, I want to exclude considering Safety stock while doing net requirements calculation
Kindly tell me the setting i have to do
regards
palaniappan

Dear Planiappan,
In IMG Production + Material Requirements Planning + Planning + MRP Calculation + Stocks + Define Safety Stock Availability maintain 100% in AvSafetySt field. So in planning your 100 % safety stock will be considered.

MRP planning and Availability check

Dear Friends ,
We are updating Availablity check in the MRP view for all materials in materials master , While running MRP system is considering ATP check as per SPRO settings defined for Availablity check group .
Weare not conclude what is the relation for MRP run and availablity check , or any seperate SPRO settings available for MRP on availablity.
If we not assigned the Availablity check in MRP view what will happen if during MRP run ?
thanks & regards
Suresh Babu.S

Suresh,
MRP does not look at what you have configured for Availability check. These two are independent from each other.
As given in Help,
In the planning run, the system carries out the following partial processes:
1. The system checks the planning file entries. Here, the system checks to see whether a material has been changed in some way relevant to MRP and should therefore be included in the planning run (see Checking the Planning File Entries).
2. The system carries out a net requirements calculation for every material. Here, the system checks to see whether the requirement quantity is covered by available warehouse stock and fixed receipts from Purchasing or production. If the requirement quantity is not covered, the system creates a procurement proposal (see Net Requirements Calculation).
3. Then the system carries out the lot-sizing calculation. Here, the system takes the lot-sizing procedure and, if necessary, the rounding up or down values into account (see Lot-Sizing Calculation).
The system carries out scheduling to calculate the start and finish dates of the procurement proposals (see Scheduling).
4. The system determines the type of procurement proposals. Depending on the settings, the system creates either planned orders, purchase requisitions or schedule lines for a material (see Determining the Procurement Proposal). If you have maintained the necessary specifications for procurement quota arrangements, the system determines the source of supply which it assigns to the procurement proposal (see Quota Arrangements).
5. The system recognizes critical situations which the planner has to processes manually in the planning results. For this purpose, the system creates exception messages and carries out a rescheduling check (see Creating Exception Messages and Rescheduling Check).
Availability check is not a planning process, it is basically a CHECK, based on the Scope of check derived for that Particular transaction, system check the availability of a material and it can confirm or propose the possible availability date.
In short if a material is defined with Check Group "KP", but with MRP type PD, still MRP would creates procurement proposals if the demand is more than the stock+recipets.

Regarding mrp pr requirement

Dear Gurus,
we are working on MRP
Through MRP purchase requisitions are raising on date basis.
i.e. suppose in aweek raw material is required @ 100 KG.
with referance to BOM & Qty of header level it raises 5 purchase requisitions.
I require the system should raise one PR consolidating the qty of 5 PR.
so that i can assign one PR to the delivery schedule
is it possible. ?
confirm the custmising & process.
thanks in advance.
suhas inamdar.

Suhas,
What you are describing is 'Periodic Lot Sizing", which means basing the procurement proposals on a time period.
This is effected by making the appropriate changes in the Material Master of the materials you are planning. I believe that the Lot Size (MRP1 tab of Matmaster) you want is the standard SAP lot size WB, 'weekly lot size'. If you select this SAP standard lot size, no other configuration is needed.
In this case, when MRP is performing its net requirements calculation, it finds the first instance of a shortage. It then looks forward in time for all additional uncovered requirements, for one week, and then it proposes a single proposal (purchase req) that will satisfy the entire set of requirements, regardless of parent part.

Rescheduling horizon impact on net requirement calculation

Dear MRP experts ,
What is the impact of Recrudescing horizon on net requirement calculation .
Regards
Sasikanth

Dear Sashikant,
The rescheduling check is used to change the dates of already existing firmed receipts not planned on the same day as the requirement to suit the requirement date.
If you look at MD04, the rescheduling date is based on the Stocks Requirement date.
In the net requirements calculation, the system checks whether warehouse stock or firmed receipts are available to cover requirements. If a material shortage exists, the system usually creates a new procurement proposal.
Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.
hope it helps. please revert back.

Alok Tiwari

WIP flag MRP net

Hello,
can somebody explain the usage of the "MRP net" box within the Material Requirement screen?
In the past with 11i this was set as default, now in R12 it is not set for Non-Standard Wip Jobs.
We are using Non-Standard Wip Jobs for Repair.
Can we change this? What impact this will have?
We are using MRP and also Manufacturing Wip Jobs.
regards
Ilona

Dear,
Length-based MRP is designed to deliver optimal allocation of requirements (length items in sales orders, for example) to available stock and production. This is achieved by ensuring that real-time changes in the stock/ requirements situation are taken into account by MRP. Allocation of stock to requirements is carried out by APO modules with different control logic. Customer specific logic can be implemented for that.
Hope clear to you.

Date of required availability of a purchasing order

Hi,
Is there a way to get the date of required availability for a list of purchasing orders (PO)?
What I'd like to do is extract the list of all open POs with the date they are required for production to see if they are late or not. I'm not talking about the PO delivery date that was agreed with the supplier. I'm talking about the date the material in the PO is required in order not to delay the production.
I know that I can see the date of required availability of a material in MD04 but it's only one material at a time and not really good to do reporting.
Thanks

Xirpinu,
Unless you are using MTO for both the parent and the component, the only way to determine the requirements date for a given Purchase order would be through a calculation, which you would have to develop.
Rather than try to create this calculation, and then commit it to a report, why not use the tool that was intended to manage this issue - MD06.
If you execute MD06, and select exception group 7, you can find all exception messages for a material that would require you to pullin (msg 10), pushout (msg 15), or delete a purchase order (msg 20). For your purchased parts, this would be the ones in which the requirements date/qty is inconsistent with the Purchase order delivery date/qty. If it became necessary to determine the requirements date, MD06 supports branching directly to MD05, where you can apply whatever logic you wish to determine the requirements date.

MRP Dependent requirements - How to define

Hello.
If I set "1" in MRP Dependent requirements field the Depended Requirements are excluded, but also the Order reservations.
Can i somewhere set so that only depended requirements are excluded and not the rest?
Thanks in advance.
/Gherry Svantesson

Dear,
In the MRP dep.requirements field, you set the indicator to 1 so that dependent requirements (reservations) are not planned.
You do not set an indicator in the Cross-project field for the availability check. This means that only the individual segment (segment of the production lot) is checked during the availability check.
Thanks,
