Strange MRP behavior - creation of schedule lines we don't need

We are having a very strange MRP issue that I'm hoping there's a solution for. If MRP looks something like this (extremely simplified):
04/16 SchLine 100
04/17 DepReq 100
05/16 SchLine 100
05/17 DepReq 100
06/16 SchLine 100
06/16 DepReq 100
06/28 --- Time Fence ---
Now a requirement comes along that increases requirements by 50 on each of the DepReq lines. MRP wants to increase each of the SchLine lines by 50, but must put them after the time fence. So far everything still looks Ok.
04/16 SchLine 100
04/17 DepReq 150
05/16 SchLine 100
05/17 DepReq 150
06/16 SchLine 100
06/17 DepReq 150
06/28 --- Time Fence ---
06/29 SchLine 50 (reschedule message, 4/16)
06/29 SchLine 50 (reschedule message, 5/16)
06/29 SchLine 50 (reschedule message, 6/16)
We can't put these where SAP wants them. We combine them into one schedule line for 150 and put it just inside the time fence. Now here's the problem. When we re-run MRP, it RE-CREATES the schedule lines for 50 so it looks like this.
04/16 SchLine 100
04/17 DepReq 150
05/16 SchLine 100
05/17 DepReq 150
06/16 SchLine 100
06/17 DepReq 150
06/27 SchLine 150 (the line we added)
06/28 --- Time Fence ---
06/29 SchLine 50 (reschedule message, 4/16)
06/29 SchLine 50 (reschedule message, 5/16)
06/29 SchLine 50 (reschedule message, 6/16)
How can we prevent it from re-creating the schedule lines for 6/29? We've already added 150 on 6/27. We can increase that quantity on 6/27 to one million, delete the three lines on 6/29, and SAP will still re-create them the next time MRP runs.
Thanks,
Randy

Hi,
Depending on the MRP type you have defined , procurement proposals are firmed and scheduled within the planning time fence.
Hope have defined a Time fence and MRP type P1 , the procurement proposals inside the fence are firmed automatically and hence to compensate for the shortage (new reqmts), new proposals will be created on the end of PTF.
yopu can choose from the following firming types:
0 -- Procurement proposals are not firmed automatically. No firming takes place with this firming type.
1 -- Procurement proposals within the planning time fence are firmed automatically as soon as their date is at least one day before the end date of the planning time fence. The date of new procurement proposals created in the planning time fence is moved to the end date of the planning time fence. As a result, these new procurement proposals are not firmed.
2 -- Procurement proposals within the planning time fence are firmed automatically as soon as their date is at least one day before the end date of the planning time fence. No new procurement proposals are created automatically within the planning time fence; that is, the shortage situation is not adjusted within the planning time fence.
3 -- Procurement proposals within the planning time fence are not firmed automatically. All procurement proposals required to cover the requirements are moved to the end of the planning time fence.
4 -- No procurement proposals are created automatically within the planning time fence; that is, the shortage situation is not adjusted within the planning time fence.

Automatic creation of Schedule line after MRP RUN

Hi,
Till now we are using only PO for placing orders to vendor, now we want to use the functionality of scheduling agrement, so that after MRP run, we can get automatic schedule line creation, for this , what are settings required, how system create the automatic schedule lines based on which criteria, second thing while creating on eschedule agrement i found that the conditon which i can add for a vednor in ME21N that all condition are not coming while creating schedule agrement even my vendor is same for PO and Schedule agrement, so what are the setting required for this.
regards,
zafar

Hi
1.In material master purchasing view data auto PO is to be flagged.If scheduling agreemet with release documentation.
Then flag JIT indicator 1.
2.maintain MRP views in material master
3.In source list for fix vendor,source list usage 2 is to be maintained.
4.Vendor master purchasing data auto PO indicator is to be flagged.
5.Then when you run MRP automatically schedule lines are generated.
For JIT and forecasting maintain creaton profile in OMUP transction.
Assign the creation profile in scheduling agreement.

MRP creating multiple delivery schedule lines in PR

Hi,
We have activated MRP (type PD) where Purchase requiesition is auto created by system for requirement quantity. We require to optimize delivery schedule in such a way that entire PR quantity is broken into various delivery schedule based on planned delivery time and requirement. Scenario can be further explained with following example.
Material Requirement for a month is say 1,25,000 units
Closing Stock say 25,000 units
PR Generated by system for 1,00,000 units. The entire quantity is schdulled with only one delivery schedule line as per planned delivery time.
The requirement is to generate multiple delivery schedule lines automatically in Purchase requisition based on planned delivery time so that Purchase orders can be placed with system generated delivery schedule lines.
How can it be achieved ?
Regards,
Nirav Kinkhabwala

Dear
Are you dealing with Single vendor where you want Multiple Schedule Line item through single PR which should be generated through MRP run ??
What you will have to do is to set up the Outline Agreement or Info Record for your vendor and material and then create the source record for this vendor- material relationship and make sure that this source record is set as MRP relevant. Once MRP is run, the vendor is automatically defaulted to your PRs. If in your material master, you have defined the same purchasing group for various material numbers, then with Transaction ME59, it is feasible that you can combine various PRs of the same purchasing group by flagging onto the 'Per Purchasing Group' indicator checkbox. Make a trial test and let me know how it goes.
Or you can use Qouta arrabgement in that case for different vendor .Please refer : Multiple Requisition line itme for Quota arrangement
Just check and revert

MRP Area and SA Schedule Lines

Hello All,
We are looking at using MRP Areas and noticed it can not be turned off once on (ECC 5.0). Given that, is the following true with reference to schedule agreements:
- Will seperate schedule lines be created for each MRP Area (same material)?
- Does the receiving storage location come from the material master or the MRP Area (Does it matter if it is a type 01 or type 02 MRP Area)?
- Is it possible to define differen't receiving slocs in a schedule line for a Plant MRP Area?
Thank you,
Jerry

Thank you Charlie,
The link is helpful however it doesn't come straight out and answer the questions - meaning there is a bit of ambiguity there.
It would be appreciated if you or anybody that is using MRP areas with schedule agreements is doing the above.

Jerry

Automatic creations of Schedule lines

Hello Everybody,
My client requirement is, Once we run the MRP, the schedule lines has to be converted automatically.
What are the steps needs to be carried out .
Is there any backend settings needs to be done.
Plese reply me as early as possible.
With Regards,
Bhaskar.

Hi,
- Plant should be MRP active.( SPRO)
- Maintain material master MRP views with MRP type , correct procurement type( External).
- Source list to be created for the SA with MRP indicator 2 and fixed indicator check.
- Requirements of the material should fall in the planning horizon, else the schedule lines will not be created.
- On the selection screen of MRP run, select the option 3- Schedule lines for the field Delivery schedules.

PR created after MRP run, instead of schedule line

Dear all,
I want to create schedule lines automatically from the planning run, for raw material. I have maintained info record, scheduling agreement, quota arrangements and also the source list.
For the raw material, safety stock of 1000 nos. has been maintained. The current stock of the material is 0.
After MRP run, based on the upper level PIRs, schedule lines are generated properly. But, against the safety stock of 1000, a PR is generated.
I donot want a PR to be generated.
Please suggest a solution.
Thanks in advance,
Shrenik
Edited by: Shrenik on Mar 8, 2008 4:17 PM

Dear all,
I checked an found that the schedule agreement date does not have any effect. Even if the requirement date falls outside the date range, i am able to create schedule lines.
I also found that if i maintained GR processing time, then always a PR is created. If GR processing time is 0, then only schedule line is created. Moreover, planned delivery time does not have any effect on the calculations, even if it is 10 days, 20 days or 900 days.
Can someone please clarify all these? How are these times taken into account?
Thanks in advance,
Shrenik

Deletion and creation of Schedule line for Line Item

Hi BW Experts,
In P.S.A. when i have checked for first schedule line 001 reqdelqty is 50 , after deleting 001 and after creation of second schedule line in R/3 there are two records transferred from R/3 for schedule line 002 first with reversal indicator 'X' and delivery quantity -50 and next record with Reversal Indicator blank with value 50. which in turn results Reqdelqty zero.
Reason of wrong data in BW: -
Schedule line category for an item is being deleted forcefully. R3 doesnt allow deletion of a schedule line category if delivery is already created. Here user is creating one same schedule line and then he deletes the order quantity from earlier one. This forces system to pick up schedule line 2 in the document flow
· User shouldnt delete schedule line.

Hello Ganesh,
Schedule line number sequence will not be in control of the user.
once delivery for a schedule line is completed, no way you can delete the schedule line (except renumbering case). This is general SAP logic relates to schedule lines.
Let me know how they are deleting the schedule lines even though delivery is completed.
Now coming to Data load problem in BI.
When you delete schedule line 001, the generated record should be with schedule line 001 with Reversal Indicator as R and delivery quantity -50.
And for new schedule line 002, reversal indicator as blank and delivery quantity 50

To generate Schedule lines for scheduling Agreement when MRP is run.

Hi,
Please help advise on my following requirement:
When I run the MRP for 'Single Item - Multi level' (MD02) for a material, I want MRP to generate delivery schedule lines for that material in Scheduling agreement.
Please advise as to how i can go about with this.
Regards,
Manju

Hi Manju,
For this you need to set creation indoactor for planning run in SPRO.
The path is spro-MM-CBP-Carry out overall maintenance of plant parameters-Click on maintain-give your plant-click on external procurement under planning run-here you can give your option for the schedule line creation.
Traction code is omi8. Hope this will help you.

SCHEDULING AGREEMENT AND SCHEDULING LINE CREATION

Hello Guys,
I trying creating a scheduling agreement(SA) for vendor & material combination.
I have created a Scheduling agreement in ME31L then maintained in ME38.
In ME38 i have also mentioned the delivery date. when i am checking EKKO for Purchasing document , its created with the delivery date specified.
My question is how to create a schedule line ? Do we need to maintain a source list of that material, plant and vendor.
If we have the source list maintained, then what is the next step after SA is created and maintained.
Do we need to do MIGO? because i tested by creating one SA in ME31L and maintained in ME38. I mentioned the delivery date as today and when i checked EKKO table the Purchasing document is created.
Do i need to create a Purchase Order?
If no then do i need to do MIGO? If i need to do MIGO, for what reference do i need to do MIGO???
My client never maintained a Scheduling agreement, they want the scheduled lines to be created and sent to vendor and we need to receive the goods on specified delivery date.
Help will be appreciated.
Thanks.

Hi,
You need to make a distinction between the scheduling agreement (ME31L/ME32L) and the delivery schedule creation (ME38/ME84)
With ME31L you create the scheduling agreement. In the scheduling agreement which is created for a vendor you maintain the parts that you will order at this vendor, the target quantity that you will order over a certain period and the price.
In ME38 you use the scheduling agreement number that is created with ME31L to create schedule lines (manually). These schedule lines consist of a date and an quantity. This is the data that needs to be transmitted to the vendor and against which the vendor is shipping the ordered materials.
Once the vendor ships the materials you post the goods receipt in Migo against the scheduling agreement number.
That is the basic working of the scheduling agreement and the delivery schedule.
Now some remarks.
You need to set-up the required output conditions for transmitting the data to the vendor either via print, fax, email or EDI.
You can do this manually in each scheduling agreement and each release but typically you maintain the output condition records.
For scheduling agreement contract (ME31L) you use transaction MN07.
For the delivery schedule (ME38/ME84) you use transaction MN10.
In order for you to be able to post the goods receipt the delivery schedule needs to have been transmitted otherwise you will get a message that not requirement are found when trying to post goods receipt.
Also the goods receipt can only be posted if the requirements are valid on the day that you are performing MIGO. This means if you would post GR today then the open requirements in the scheduling agreement need to be for today or already from previous dates. The system will not allow you to post GR for quantities that are only due tomorrow (if this is required a user exit needs to be set-up).
If you want schedule lines created via MRP then you need to set-up a source list using ME01. You have to make sure that the MRP key is set to 2 in orer for the system to generate schedule lines and you also have to make sure that you have the correct MRP parameters set-up.
You can use ME84 to transmit the delivery schedule lines generated by MRP if no changes are required. With the ME84 you can transmit multiple releases at once, however this transaction can not be used to make manual changes to the MRP proposal.
The scheduling agreement offers lot's more possibilities but the above should get you going with the basics.
Hope this will help you on your way.

Schedule line date changes after each MRP run

Dear Experts,
Clarification needed on how the system plans the MM schedule lines.
Setting: Start in the past not allowed.
3 days for processing of order
The issue is after each MRP run the system is moving the schedule line to the current date + 3 days for processing + the planned delivery time.
If the schedule line is not firmed, after each MRP run ( which happens everyday) the system is moving the schedule line and then giving an alert saying the " order has to be rescheduled to the previous day"
on the second day after the mrp run the system moves the schedule line again by one more day and gives the rescheduling date as " -2 days from today"
this change is happening every day after the planning run. - because of this there are really no backorders ( schedule line in the past ) in the system. we were not able to know if the vendor is actually delayed in this case.
can you kindly suggest what went wrong here ??
we are using strategy 10 for the planning of procured parts. Let me know if more info is needed.
Note: we are also using stock transfer process for some procured parts. there too the PR date gets changed after each MRP run. There there is no lead time in this case. the order is placed on the same day as the requirement as both plants are nearby. There the PR date is changing everyday to the current date.
your advice would be of great help
thanks
Nagendra Kumar

Hi Caetano,
thanks for your suggestion
Yes, we use firm zone for few of the vendors. there the system don't change the schedule lines.
Also for the stock transfer PR's there is no firm zone and the lead time is one day. in this case it changes everyday after the MRP run.
the stock transfer PR's leads to the creation of Schedule lines from the source plant. Since this PR gets changed everyday. the alerts coming out of MD07 gets changed and we really did not know if this order is delayed or not. In the source plant we use the firm zone to avoid moving the schedule line. But then the alerts are always not correct.
is there any setting which helps in not moving the PR everyday without using " start in the past"
thanks
Nagendra Kumar

Creation date for schedule line

Hi All,
I have a scheduling agreement. MRP is generating the schedule lines properly. I want to know any table or any other way by which I can check the creation date for those MRP generated schedule lines.
Regards,
MHP.

Dear Manish,
As per my understanding from your question, you can use 'MD04-Stock/Requirement List' transaction for checking all the dates for planned order generated from MRP run.

MRP Type P1 and late firm schedule lines

Hello All,
     We are using MRP Type P1 which firms our schedule agreement schedule lines within the planning time fence (as desired). However, sometimes the supplier is late on delivery and the firm schedule line goes into the past.
     Is it possible to have MRP move the firm schedule line delivery date to today instead of going into the past?
     Thank you,
     Jerry

Hi ,
Bring process forward (reschedule in)
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.
It does not take in to account the GR processing time and it is purely based on the stock requirement date , parameters in Procurement and Scheduling in the Material Master
So it will consume the requirement backward scheduling and bring the Process forward.
Kumar which strategy are you using ? scheduling agreement is of weekly , daily or monthly bucket ?
How many days SA bring to Production and How many days SA for forecast you are doing ?
Are you using any Program to convert these SA in to PIR and upload ( using any program ) .
Regards,
Jayavimal

MRP - PRs being generated along with Schedule lines

Hi
Problem statement - PRs also getting generated alongwith schedule lines in MRP.
We have 'PD' MRP type set up for externally procured material with 'F'. I had set up to generate schedule line using the sourcelist. and during the planning run MD03, I am selecting the following values
Create PR - '2' Purchase requisitions in the open period (any value in the three generates a PR/Planned order in the open period)
Delivery Schedules - 3 Schedule lines.
The client requires only generation of schedule lines. How can I get this done.
regards
Nagaraj

Dear Nagaraj,
For MRP to create the schedule lines automatically, please change to the following settings.
1. Create Scheduling agreement for the vendor,Agreement type LP.
2. In ME03, Source List: Maintain MRP = 2 Record relevant to MRP. Sched. lines generated automatically.
3. Run MRP
Hope this helps you.
