Scheduling in MRP Run MD02

dear all,
i still confuse for using scheduling in MRP run MD02,
what is the use of using both scheduling type "1" and type "2"?
because if i run the MRP using scheduling type 2,  after i generate the planned order, then i can see the capacity planning evaluation,
but not if i run scheduling type 1
if i run the scheduling type 1, how can i analyze the capacity planning?
until now, i always run the scheduling type 2, because i think it is more useful to run scheduling type 2,
so what is the plus and the minus using scheduling type 1 or type 2?
best regards,
MARUFAT

Hi,
In simple words:
The main difference between scheduling type 1 (Basic date scheduling) & Scheduling type 2 (Lead time scheduling & Capacity requirements) is from which records MRP reads the values.
Basic dates is more like a rough scheduling where the values are read from the material master & the exact operation times are not considered or capacity requirements generated.
Lead time scheduling is more precise meaning for each in-house produced material it reads the routing & checks the time maintained for each operation, it then calculates the exact times for each operation based on the working days, shift timings, breaks & also generates capacity requirements.
Now what is the criteria to select... it depends on the business requirement. But the data maintenance for Scheduling type 2 is higher as compared to Scheduling type 1.
What is the benefit for going for Scheduling type 2.... well it gives you a clear picture on your production planning process & how much capacity is required, whether you have the requisite capacity etc etc.
Basic date scheduling is preferred when you do not want such fine control on your production planning process.
For more info refer to SAP help, it should make it more clear.

Vivek

  • No Purchase Requisition Generated after MRP Run MD02

    Hi All,
    After runing MRP Run MD02 for finish product with MRP Control parameters for create purchase requisition as 1 (Create Purchase Requisitions) . System is not generating any purchase requisitions for raw materials required for assembly.
    If we select 3 create planned order system is able to generate planned orders for raw materials required for assembly.
    Plz guide why am not able to generate purchase requisition directly.
    Regards,
    Sipra

    Sipra,
    Couple of checks,
    1. Check whether the Material is defined for "F" - External Procurement in MRP2 view of the material master.
    2. Check whether the material type used for the material is enabled for "External Purchase orders". Transaction OMS2.

  • Scheduling agreement MRP run

    Hi All,
    We use Scheduling agreements for purchasing spare parts. The nightly MRP run checks the warehouse requirements and creates delivery schedule line to scheduling agreement.
    Now the MRP run creates unnecessary delivery schedule lines to scheduling agreement if the earlier created delivery schedule line's delivery date has been changed manually.
    Today the MRP run finds requirement for article XYZ and creates the delivery schedule line, where delivery date is 2.9.2008 (determined from articles basic data).
    The Vendor confirms the delivery date as 3.10.2008 and the purchaser changes manually  (transaction ME38) the delivery date to delivery schedule line accordingly and prints the created message.
    The next MRP run creates new delivery schedule line, where delivery date is again 2.9.2008.
    After that there are two open delivery schedule lines for article XYZ with delivery dates 3.10.2008 and 2.9.2008.
    Why the MRP run does not notice the existing delivery schedule line with the new delivery date 3.10.2008?

  • Dates for Backwards scheduling when MRP Run

    Hello experts,
    When MRP run, which calendar does SAP take to schedule planned orders? where could I indicate it?
    Thanks in advance.
    Laura

    Thank you all,
    I have checked the calendar that is assigned to my plant, and, as you have said, is the one that is taking into consideration to determine the dates.
    In my case, Saturdays and Sundays are not workdays. As a result, every purchase requisition has its release date assigned to a workday.  What I have noticed is that although Saturdays and Sundays are not work days, planned delivery time and In-house production time is taking them into consideration to calculate the release date. What I mean is that those two fields are defined as calendar days. Is that correct??
    Thanks again.

  • Purchase requisition  number Range in MRP Run (MD02)

    Hi Experts ,
    When I run the MRP through T-Code MD02 even in test mode the Purchase requisition number getting consumed with out saving the entries.
    for eg:- number range = 100 to 200.
    when I execute the MD02 by selecting the indicator "Display results before they are saved " system showed a Purchase requisition number 100 and exit with out saving the entries.Next time when I execute the same MD02 system is displaying the purchase requisation number as 101, where as i have not used PR number 100 at all.
    Please guide me....
    Regards,
    Sri.

    Sri,
    Nothing is missing.  This is standard behavior.  It appears to me that SAP makes no effort to ensure that all Purchase request numbers are contiguous.
    You can try turning off number range buffering.  This will reduce the number of gaps in your purchase req number sequences.  However, I don't know if it will eliminate all gaps.  Be aware that there is a performance tradeoff when you deactivate buffering.  Making this change is considered to be a system modification, and is not supported by SAP.

  • Sales order link to MRP run

    Dear gurus,
    I have one query regarding sales order link to MRP run.
    I had created sales order by VA01 & also independent requirement in MD61.
    Both are acknowledged in MRP run.I know the requirement in MD61 transferred for MRP run(MD02/MDBT/MD01).
    But my question is how sales order requirement considered in MRP run i.e. link to MRP run.Is there any customization?
    Pl.suggest the same...
    Rg,
    Tushar

    Hi,
    Strategy 11  :-
    Sales Order creation - no impact.
    BSF    Gross planned independent requirements 
    KSL    Sale from stock without independent                                                                               
    Requirement reduction
    Goods Receipt - minus the quantity for the oldest planned independent in demand management. For e.g. if PIR is 100 and delivery 90, PIR becomes 10 (withdrawal 90).
    Delivery - no impact as delivery is issue from sales order.
    Hope clear to you.

  • MRP run but no planned order creation

    Hi ,
    I use MD61 to create PIR , i can saw PIR in MD04 sceen.
    Then i run MRP via MD02 there is no planned order be created.
    But if i run MRP via MD43 , the planned order appear .
    Could anybody can help on the topic ? Thanks !

    Dear Denny Sheng 
    i think you are asking about two different things:
    1) you have enter PIR in md61and those are reflected in md04,but when you take MRP Run( md02) planned order are not created.This is because there must be stock of material available
    2) The planned order are created when you run md43.This means you have selected MRP Type MPS.please check .

    Hi,
    In transaction OMDT you have to enable the indicator create schedule lines
    In MD02 MRP control Prameter here select the Delivery schedules -3- Schedule line. Processing Key as NETCH and Planning Mode - 3 delted and recreated.
    Maintain source list ME01, in that put MRP indicator as '2' i.e. schedule lines via MRP.Put your agreement no in that.
    If u run MRP properly u will get schedule lines automatically in ME38.
    Make the schedule agreement, make it source relevent in the source list make is FIX and MRP indicator as 3.

  • Schedule Lines are not getting generated after MRP run.

    Hi,
    I have an issue where a SA exists for the parent material with item category L (subcontracting). The parent material has a valid BOM and some sub components as well. I see in CS03 that BOM is fine with validity dates for the parent material. A valid source list also exists for the parent material where SA is present as the source of supply with MRP indicator as 2. Now when i run MRP for the parent material using MD02 (NETCH), with indicators as below:
    Create pur.req.  2
    Schedule lines   3
    Create MRP list  1
    Planning mode   1
    i don't see any schedule lines in MD04. Instead it creates a PR that too without any source of supply.
    In master data for the parent material MRP type is PD with Procurement type F and special procurement key 30. I have checked and every thing seems to be fine still MRP run doesn't create schedule lines.
    Any help is appreciated. I can give more info if required.
    Thanks.

    Dear Rakesh,
    Scheduling agreement:An outline agreement against which materials are procured at a series of
    predefined points in time over a certain period.
    1.For this you have to first use ME31L for creating scheduling agreement and then ME38 for maintaining scheduling agreemnet
    schedule.
    2.Ensure in the source list after maintaining the material,vendor combination the setting for MRP relevancy is set to 2 - Record
    relevant to MRP,Schedule line generated automatically.
    Moreover you have to use value 3 for delivery schedule line which is one of the MRP control parameter while taking MRP run.
    So for the materials for which scheduling agreement exists,schedule lines will be generated.
    Check and revert back.

  • MRP Run error " Schedule Lines not generating properly"

    Hi Folks,
    I am facing a typical issue with MRP Run.
    Every time when I am running the MRP for a particular material I have made settings such that Schedule lines to be generated by maintaining the Source list and MRP relevancy as 2 in source list. Also I have fixed the vendor. Now my problem is I am getting Schedule lines for first run and Combination of Purchase requests and Schedule lines or only PRs for the next MRP run.. This is keep on repeating in such as way that the planning is shifting as said above for subsequent MRP Run.
    Note that the initial settings during MD02 remain same for all run.
    I want only schedule lines to be generated but not PR.
    Pls advise and provide input where the wrong might be.
    Quick responce would be appreciated.
    Regards
    Shash

    Dear shash,
    Check with What are the MRP control Parameters values which you are using for the MRP run.
    In MD02, For Deleivery schedules run with value 3 - That's -  Schedule lines.
    The other options are     1  No schedule lines
                                       2  Schedule lines in the opening period.
    check with this & revert back.
