MRP Settings - Minimum Lot size / Saftey stock /Lot Size

Hi
I am confused about some of the settings , We set M1(Monthly lot size ) and PD MRP type settings, We maintained the Minimum lot size as 2500 lb and the safety stock as 300.
I tested by changing the Parameters , I am confused.
Please clarify me
Did MRP is going to suggest the PR once if the stock went below 300 ?
Did MRP is going to wait for the PIR to get accumulate the Minimum lot size settings ?
What will happend if the time bound is beyond a month ?
Please help me to understand the concept
Thanks
JJ

Hi,
Use tcode OWD1 to create rounding profile.
Select create icon for creating new rounding profile.
Input new profile name.
In that Threshold value & Rounding value is available.
Input your value & save.
In MRP1 view give the input of rounding profile.
Example given below for easy understanding.
Threshold value Rounding value
    1- 20 -
>                20
60- 100 -
>              100
900-1000 -
>           1000
8000-10000 -
>     10000
If your requirement is 7, it will convert to 20.
If your requirement is 23, it will convert to 40.
If your requirement is 76, it will convert to 100.
If your requirement is 435, it will convert to 440.
If your requirement is 844, it will convert to 860.
If your requirement is 910, it will convert to 1000.
If your requirement is 8045, it will convert to 10000.
Hope it will helps you.

Maximum Lot Size & Maximum Stock Level

Hi All,
In MRP 1 view we have Max Lot Size & Max Stock level, how the system give me requirement if i'm maintaining these fields.

Hi Ashok,
If you mainatain Max lot size system will check for this qty & it will not allow to generate PR or planned order more than this qty in MRP run & Max stock level is the stock for replinshment where lot size if replinishing.

Rounding Value,Minimum Lot Size and Maximum Lot Siz parameters

Hello Gurus,
Please explain me the what is the use of the parameter Rounding Value
,Minimum Lot Size and Maximum Lot Size parameters in the product master and how does it in impact during the Heuristic Run?
Thanks.

Rounding value is the incremental quantities in which the order can be produced/procured. Eg. if orders are possible with quantities 40,60, 80, 100 etc..then rounding value is 20.
Min lot size is the minimum quanity in which order can be produced eg. 40 in above example
Max lot size is the maximum quanitity in which the order can be produced/procured. eg. 100 in our example
Impact on Heuristic run: heuristics takes all the above parameter to plan supply order. eg. if requirement is 55, it will supply plan for 60. If requirement is 120, it will produce two orders - one for 100 and the other for 20. if the reuqirement is 10, the order size will be 40.
Hope this helps.

Lot Size "WB - Weekly Lot Size"

Dear All,
I have selected lot size "WB - Weekly Lot Size" for a material.
The Planned week start day is Monday in planned calender.
If i run MRP for the above maintained material it is not flowing the requirment and it is not combined on Monday, it is throing on Tuesday, Thursday and all the other day including MOnday also.
Why is this system is not throwing correctky the requirment on every MOnday.
Is there settings need be done to get this.
Your valuable answer will be appreciated.

Please read SAP online help:
http://help.sap.com/erp2005_ehp_04/helpdata/EN/f4/7d282c44af11d182b40000e829fbfe/frameset.htm
Please check your settings in SPRO:
SPRO > Production > MRP > Planning > Lot-Size Calculation > Check Lot-Sizing Procedure
...here you can check "Scheduling" field (V439A-TERBV) of lot size "WB". And you can check also field V439A-LGTER.
F1 help for the field:
Scheduling for period lot sizes in short-term area
This indicator defines the time in the period the system is to create the availability date or the start date for the lot for period lot-sizing procedures.
The availability date is the date on which the material, including the goods receipt processing time, is available again. In the MRP list, the availability date is equal to the MRP date.
In in-house production, the start date is the order start date, in external procurement the start date is the release date.
The following procedures exist:
Availability date equal to requirement date
Availability date at period start
Availability date at period end
Start date at period start
Planned order start date at period start and availability date at period end
With this setting, the in-house processing time in the material master record is ignored.
Note
The following is valid in all cases:
If the start date lies in the past, the system switches to forward scheduling. The following example illustrates how the system procedes:
The period start is Monday and the period end is Friday. The planned delivery time is 8 days. The indicator for determining the date is set to, "availability date at period end".
Today is Monday, a requirement is planned on Wednesday. The system has to schedule forwards. As the system works using date determination, today's date is not selected as the start date. Instead, the system determines the next period end, and uses backward scheduling to calculate a start date that does not lie in the past. This means that the end date was planned for the Friday of next Week.

Inspection lot w/o stock tab

Hi Guru,
We receive job work items through MIGO and MB31.
During MIGO , create one inspection lot w/o inspection lot stock tab and again create one more inspection lot at the time of MB31.
Pl. suggest any setting so that only one inspection lot will create after MB31.
Regards,
Rakesh Patel

Hi Rakesh,
Kindly excuse me but thereu2019s a confusion to me, if you can please clarify the same.
1.     First transaction that you are carrying out is MIGO for 101 movement I guess.
2.     For this movement you are observing that inspection lot stock is not getting generated. The probable one of the reasons for this according to me is, goods receipt against cost center using item category K in PO.
3.     When you inward such material against K, the stock gets consumed at the same moment you inward it. This is standard behaviour of SAP.
My question is,
1.     MIGO is done for say material XYZ. (the stock is not visible in MMBE if you have inwarded against cost center.)
2.     Now MB31 is done for which material? Is it the same material or different? If you have activated 04 inspection type to the material whose production you are declaring then system will generate the lot for it in 04.
3.     MB31 is generally used for goods receipt against production order.
I am unable to establish the link between MIGO and MB31 here.

Anand Rao

'Start of Lot Size Grouping' and 'Lot Size Strategy' parameters

Hello,
For "by period" lot sizing procedure, could anyone explain the difference between:
- "Start of Lot Size Grouping" flagged with "Lot Size Strategy": 1
- "Start of Lot Size Grouping" flagged with "Lot Size Strategy": blank ?
I have played around with both options and both produced the same result. If anyone could provide some insight , I would appreciate it.
Many thanks in advance.

Hi Datta,
Thank you for your help.
You indicated that the "The first period of the grouping horizon can be different than the period in which demand exists".
How would the first period be different? What other elements could be considered for the start of the horizon?
For example,   Periodic Lot of 4 weeks, Lot Size Strategy 1 or blank and Start of Lot Sizing Group Flagged produced the exactly same result. What is interesting about it, is that with Lot Size Strategy "blank" the group production quantity is placed in a bucket where there is no demand. The results with Lot Size Strategy "1" makes sense as I have the grouped quantity placed in a bucket where I have shortage due to Safety Days requirement and not necessarily demand.
                             w1     w2     w3     w4     w5     w6         w7            w8
Total Demand     125     42     42     41          110     37     73
Production (Planned)     223                    244
Days´ Supply     58     53     48     43     58     53     48     43
Safety Days´ Supply     43     43     43     43     43     43     43     43
Any thoughts? Many thanks in advance.

Dynamic Saftey stock

Hi Friends,
Kindly throw some light on the above topic. I have gone through the help documents & understood quite a bit but not fully though. I have a couple of questions on this: 1. In the Coverage profile settings, If i maintain the "Type of per.length" as '1 - Workdays' will it consider the workdays based on the factory calendar assigned to the plant.
2. What impact does the date on which the MRP is run has on Dynamic saftey stock calculation.
3. If i do not maintain the Min range of coverage, then when are the proposals trigerred.
Thanks in Advance,
Srini.

1. In the Coverage profile settings, If i maintain the "Type of per.length" as
1 - Workdays' will it consider the workdays based on the factory calendar assigned to the plant.- Yes
2. What impact does the date on which the MRP is run has on Dynamic saftey stock calculation- yes depends on the date you run the dynamic safety stcok will change.
3. If i do not maintain the Min range of coverage, then when are the proposals trigerred.- in this case if you have enetred target or max period then it is okay, hence system will take the next min period for calculation
See the example and help below
Define Range of Coverage Profiles (Dynamic Safety Stock)
In this step, you define the range of coverage profile for calculating the range of coverage.
Using the range of coverage functions, you can detemrine a safety stock level that is based on requirements and the range of coverage. The dynamic safety stock is automatically adjusted to changes in requirements and is fully available for MRP.
The calculation of the dynamic safety stock can be limited - on the one hand by entering maximum and minimum ranges of coverage. And on the other you can determine various period for the validity of the range of coverage.
Note
The dynamic safety stock is calculated in the planning run of the order proposal quantity. In the MRP evaluation, you can check the parameters used to calculate the dynamic safety stock in the period totals display.
The dynamic safety stock is calculated using the following formula: average daily requirements * range of coverage
The individual parameters are described below:
Average daily requirements
The calculation of the average daily requirements is carried out using the following formula:
Reqmts in the specified periods/number of days in the total period length
You must maintain the following parameters for the calculation of the average daily requirements:
Period indicator
You use this indicator to determine the calendar period for which you want to carry out the average daily requirements.
Here you can enter the following:
weeks (W)
months (M)
periods according to the planned calendar (K)
Type of period length
You use this indicator to determine the length of the individual periods in detail.
Here you can enter the following:
workdays
calendar days
standard days
If you select standard days as a period length, you must determine the number of days per period in the field, "No.standard days"
If you set standard days as the period length, you must enter the number of days per period in the "NO.standard days" field.
Number of periods
Here, you define the number of periods you use to calculate the average daily requirements.
Determining the range of coverage
You can determine the range of coverage for a maximum of three periods and you can maintain different coveragefor each period.
To do this, you must define the ranges of coverage and the periods in the screen section entitled, "Determine range of coverage".
You also have the option of limiting the range of coverage in each of the three periods by entering a minimum and a maximum range of coverage. The system checks whether the actual range of coverage ( available quantity / average daily requirements) lies below the minimum range of coverage or above the maximum range of coverage. If this is the case, the dynamic safety stock level is recalculated using the informtaion for the target range of coverage.
Example
Average requirements
Reqmts in the 1st period: 1000
Reqmts in the 2nd period: 2000
Calendar period: week
Period length: standard days (5 days)
Number of periods: 2
Calculation of the average requirements:
(1000 + 2000)/(2*5) = 3000/10 = 30
Range of coverage
Range of coverage for period 1: 2
Period 1: 2 weeks
Range of coverage for period 2: 4
Period 2: 3 weeks
Average requirements * range of coverage 1
300 * 2 = 600
This means that for the first two weeks from the MRP date, 60 pieces are planned as safety stock.
Average requirements * range of coverage 2
300 * 4 = 1200
This means that for the following 3 weeks, 120 pieces are planned as safety stock.

QM Inspection Lot Qty vs Actual Lot Qty

Gang,
What is the difference between Inspection Lot Qty vs Actual Lot Qty. And which one of these should get updated when more than one receipt is against the same Material/Batch/SLoc?
Thanks
Bruce

Inspection lot Qty & actual lot qty as I remind are most of the time same but when you do the QTy correction through QAC1 ,they come into picture...or may be when you have inspection control defined in the QM view
Inspection lot qty has significance for inspection & calculation of sample size.
When more than one receipt is against the same Material/Batch/SLoc the inspection lot QTy will be Qty for which he material document is created,

Sub contract MRP Settings

Hello
Can any one guide me , how to do MRP settings for subcontract Proces.We want the system to generate MRP for the subcontract Process, We need B & C Material to Make A. A is a finished goods , B is going to Produce and ship to subcontract Vendor and C will be Procured and directly shipped to Subcontract Vendor . We are going to get back A as a finished Goods. Can any one please tell me what will be the MRP Settings required to create a Sub contract Purchase Requisition ?
Thanks
JJ

Hi,
For material B, it is a inhouse production. Set E - inhouse production in MRP2 view.
For material C, it is a External procurement - F, assign in MRP2 view. For material C, maintain delivery place at Subcontract place in MIGO screen, so that material directly dispatch to subcontract place.
For material A, external procurement - F, maintain in MRP2 view. Maintain BOM for material A.
When BOM explodes, P.R will create for material A.
Send material B by ME2O 541 mvt.
And receive material A by MIGO 101 mvt.

Dharma

In process Inspection Lot Qty and Actual Lot quantity difference.

Hi Experts,
In case of In process Inspection
Scenario : 1. Production Order created, released but before saving the qty is changed.
2. Production Order created released and saved. Then qty is changed in Change Prod order txn.
These scenarios are causing a discrepancy in Inspection Lot Qty and Actual Lot quantity. Is there any method to avoid this ?
This can be made correct in Inspection lot by resetting the sample calculation. But once confirmation has started for Prodn Order (not necessarily QC operation) or RR has been done resetting is not possible.
Is this the std behavior ? Disallowing the resetting once RR done seems OK, but even if any of the operation in Prodn Order is confirmed it still give status error while resetting. Canceling all the confirmation all the way back also does not solve the problem.
Any suggestions ?
Regards
Joe

Hi
Although your suggestion is valid, it is not practical from user point of view.
Moving this thread to QM forum.

Reset the SMC > http://support.apple.com/kb/HT3964
It's clear that the battery has got enough capacity to work correctly, so something happens with the MagSafe port or its charger. If you have another charger, try it, and if not, take the MacBook and the charger to an Apple Store or reseller. It's better to do this as we don't know if the problem is in the charger or in the MacBook Pro

Finding the size of db and size of used space

Greetings all good people.
Can you please help me find out about 2 database information?
One, I want to find out the size of a database =size of physical files.
and the size of data which is the size occupied in physical files.
We are about to start a new project and there is a table on the database but it is empty.
We want to be exporting data into this table but we want to make sure that there is enough space on the db before we start populating the table with data.
I believe the code below just gives me the size of the database.
select (bytes/1024/1024) as total_gigs from dba_segments where owner='BELL' and segment_name='$TABLE_NAME
But I want to know the total size of the database and how much size has been used already, much the same as you would want to know the size capacity of a hard drive and how much of the size has been used.
Sorry if my request is confusing.
Thanks a lot in advance

db size can be found out
select sum(bytes)/1024/1024/1024 from dba_data_files ;
and size of data is -- in the datafiles
select sum(bytes)/1024/1024/1024 from dba_segemnts ;
You can find out by below query .. the tablespace sizes -- would be DBSIZE
used space -- would be the actual occupied space.
select t.tablespace, t.totalspace as " Totalspace(MB)",
round((t.totalspace-nvl(fs.freespace,0)),2) as "Used Space(MB)",
nvl(fs.freespace,0) as "Freespace(MB)"
from
(select round(sum(d.bytes)/(1024*1024)) as totalspace,d.tablespace_name tablespace
from dba_data_files d
group by d.tablespace_name) t, (select round(sum(f.bytes)/(1024*1024)) as freespace,f.tablespace_name tablespace
from dba_free_space f
group by f.tablespace_name) fs
