MRP calculation

Do SAP B1 MRP calculation able to calculate production lead time until min?

what i mean is that
whether in SAP B1 the MRP calculation will be able to calculate the production lead time until the level of minutes? since now in item master, the lead time column only can key in by days.
Thank you

MRP Calculation of days

Hi,
How in the system the calculation of days is done
My query is I have material 'A' as a raw which required 30 days of time for procurement.
After proucrement of 'A' it is consumed in 'X' material as in house production.
So while setting the the days in mateirlal master how the days are put to get final material 'X' done in 37 days.
Here how the MRP calculate the days as from starting day if am doing mrp run today.

Hi,
You are asking about how the scheduling is carrying out in SAP system.
1. There are two types of scheduling.
a)Basic dates scheduling :
This is independent of required qty. This will take time from material master mrp2 view.
b) Lead time scheduling:
This is dependent of requirement qty. This will take time from routing. This is very accurate.
2.To calculate total days(37 days):
For inhouse production, system will consider Inhouse production time( mrp 2 view),GR processing time, Opening period.
For External procurement system will consider Processing time for purchasing (OPPQ), Planned delivery time(MRP2),GR processing time(mrp2).
3.Here how the MRP calculate the days as from starting day if am doing mrp run today
Say your requirement is 100 nos on 15.03.08. Suppose if you run MRP today, system schedules the dates by scheduling types ex. Backward Scheduling, Forward scheduling, Today Scheduling (settings in tcode OPU5)from your requirement date.First it will schedule for material X then for material A.
Hope you have got some idea about scheduling.

Isseu regarding MRP calculation.

Hi Gurus,
We have MTS scenario with strategy 10 ,requirement type LSF , in MD61 PIR are present from 01 /01/2011 till today , but when i check in MD04 only requirments from 01/04/2011 are taken into consideration ( for LSF requirment after 01/04 system is showing -ve qty and plan order are generated for these independent requirement ) , i want to know why PIR from 01/04/2011 are taken into account and why older PIR are not considered.
Current stock is 0 and planning time fence in 30 days and planning horizon is 100 days,, please help me understand why older demands are not taken for calculations.
Thank you,

Hi.
I assume you have run the MRP with the processing key NETPL (Net Change in Planning Horizon). And as you have define planning horizon 100 Days that's why system is taking the requirement for only 100 days. If you want to have total requirement have to consider use MRP processing key NETCH (Net Change in Total Horizon).

Different Lead times for supplier in MRP calculation

Dear All,
We have different suppliers for a material. Different suppliers have different lead times and Min.lot size. Our requirement is when we run MRP system should suggest Pld.Order quantity for the supplier and also take lead time accordingly. I have done splits for suppliers by using Quata arrangement but system is only taking planned delivery time from material master record.
I also defined info records for the vendor and define lead time but still system is taking Pld delivery time from materials master.
Please help

Hi,
Go to OPPQ, enter your plant then click on External Procurement, there tick the check box Scheduling: Info Rec / Agreement.
This will ensure that the PDT is read from info-record if it exists.
Hope it clarifies.

I need to give packing plan for FG material. WBEXT587I1 SL AEE6 EXT BASE– 4 X 4 L
For example if requirement is 25000 liters
25000/4=6250(tin)
6250/4=1562.5(case packing) -This value i will update in PIR(MD61).
NCIFU501C1
INDUS. P.S. BLACK –
6 X 500 ML
if requirement is 25000 liters
25000/0.5=50000(tin)
50000/6=8333(Case packing)-This value i will update in PIR(MD61)
I.e
NCIFU501sfg 1=25000 liter
NCIFU501C sfg 2=50000 EA
NCIFU501C1 FG=8333EA
Like above it has to come plan wise in order report
But after running MRP then i checked in order report value its not coming correctly.
Kindly please clarify.

MRP calculations

Hi guys.
I have problem with MRP planning.
Example:
1. The quantity of the material X on the stock is zero.
2. I created one reservation for 5 pieces of the material X for 10.10.2007
3. I run planning. Purchace requirement for 02.10.2007 is created for 5 pcs.
For this moment I have planned 5 pcs of material X. The stock is still 0.
4. I create reservation for 4 pcs. for tomorrow.
5. MRP do not plan anything and I do not know why!?
Pls help me./ Points will be rewarded
Regards
Piotrek

Planning date is correct.
I have one pr.requirement planned for 5 pcs. for 02.10.2007 for the reservation I created with date 10.10.2007.
Than I deleted this reservation just to test MRP.
I created another reservation but this time with the actual date for 3 pcs.
I run planning with actual date and no pr.requirement are planned.
I think that SAP sum pr.requirement created for 02.10.2007 with reservation with actual date but I do not know why?

How to exclude some valuation type in the MRP calculation ?

Dear Experts ,
We have C1,C2,C3 as valuation types each valuation type has quantities , The problem is the reorder point will put the quantities of C3 and C2 in consideration of the reorder point
HOW TO DISABLE THIS ?????
Please Advice

Just like DB said, you must create a storage location where the MRP indicator is set as not relevant.
To do this, you can make a permanent setting in OMIR.
But for materials already extended to that location, you will have to do it manually for each material master. Do this setting in MRP 4 View against the storage that you would like to exclude from MRP.
Hope this helps..

MRP : Calculating lot size without purchase orders

Hello,
    We have some materials with weekly replenisment.
    We want to calculate the quantity by following the formula : Maximun stock - actual stock.
    The lot size procedure HB do something similar but takes into account the existing fixed receipt elements,
    How can I avoid to take that stock into account? any other characteristic? any user exit ? Any badi?
Thank you

I followed the same procedure of reverse calculation from MRP pricing calcu

hi,
sap gurus,
i followed the same procedure of mrp calculation but
MRP Pricing Procedure:
Go through the following:
I will brief your requirement in short
MRP = 1012.5/-
VAT = (1012.5/1.125) = 900/-
so price before discount will be = 900/-
discount given at the rate of 10% = 100/-
Initial Price = 1000/-.
1. Create condition types as below:
ZR00 for price
Condition class = B
Calculation type = C
Plus/minus = A
ZSET for settlement (to knock off the effect of ZR00)
Condition class = A
Calculation type = C
Plus/minus = X
ZWST for tax
Condition class = A
Calculation type = H
Condition category = D
Plus/minus = X
Z007 for discount
Condition class = A
Calculation type = H
Plus/minus = A
ZDUM for net price
Condition class = A
Calculation type = A
Plus/minus = A
YWST for tax (to knock of the previous effect - to be used for posting to G/L)
Condition class = A
Calculation type = A
Plus/minus = X
YOO7 for discount (to knock of the previous effect - to be used for posting to G/L)
Condition class = A
Calculation type = A
Plus/minus = X
2. The following will be the pricing procedure configuration:
Step......No........Cond Type........... From.........to..........Man.........Req........Sta................Acc Key
10........0..............ZR00..................--..........--..........-...........-........---.................ZDU
20........0..............ZWST..................10............19...........----.............X............X...................
30........0.............text.......................10...........29...........---...........----.........X
40........0.............Z007.....................30...........39...........-----.............X............X
50........0..............text.....................30............49...........---...........-----.........X
60........0............ZSET.....................10...........19...........----............X............--.................ZDU
70........0............ZDUM....................50...........59...........----............X............---...............ERL
80........0............Y007.....................40...........49...........----.............X...........---...............ERS
90.......0..............YWST..................20...........29...........-----............X...........---................ZWS
ZDU - dummy account key for posting extra not required items.
ERL - account key for price
ERS - account key for discount
ZWS - account key for tax.
3. Condition records in VK11
Condition type----
Condition record.......
ZR00........................................1012.5.....................INR will be positive (1012.50 +)
ZSET.......................................100%...............................will be negative (100 -)
ZWST.......................................10%................................will be negative (10% -)
Z007.........................................12.5%.............................will be positive (12.50 +)
ZDUM.......................................100%..............................will be positive (100% +)
Y007.........................................100%.............................will be negative (100% -)
YWST.......................................100%.............................will be negative (100% -)
Condition records for Z007 & ZWST will be decided as per the conversion required. You will first have to manually calculate the amount for the condition type.
4. I create a sales order for single quantity for an item & the pricing will be as under:
ZR00 = 1012.5 (dummy account) - positive
ZSET = 1012.5- (dummy account) - negative will knock off effect of ZR00
ZWST = 112.5- (negative & no posting)
Z007 = 100 (positive & no posting)
ZDUM = 1012.5 (positive & posting)
Y007 = 100-(negative & posting)
YWST = 112.5 (positive & posting)
but its not throwing any condition records for ZWST and YWST
can any body help me
plz

HI,
Plz try Routin for Vat formula.
i am worked on MRP pricing but in our case formula is different.
eg.: If i want to calculate VAT for B=1000 Rs. it is like
A=1000 * ((100/100 + (12.5- VAT 5)))
= 889
VAT (Value) = B - A = 1000-889 = 111 which is passed to GL account.
For that we developed one Routine with the help of ABAP and assign to Pricing Procedure.

SAP Add Pricing Tier Logic to the MRP Purchase Req Calculation

Hi experts,
ISSUE: SAP Add Pricing Tier Logic to the MRP Purchase Req Calculation .
> MRP currently generates purchase requisitions based strictly on a calculation of inventory, open orders, forecast, and purchase orders. The purchase req quantities do not take advantage of the pricing tiers and their associated quantity discounts. MRP may recommend a PO for 913 units. At no time would a planner ever order such a specific quantity. In addition, the planner would increase the order to 1020 to get the price discount for 1000 units (rounded to 1020 for carton quantity). SAP should include a preset order table which would evaluate the MRP calculation and recommend an appropriate quantity based on the contract pricing tiers.
pls let me know it is posible or need any enhancement and how ?
thanks
humera

Hi,
Rounding profile works for u r query, there u can maintain quantity rounding for purchase process, also the rounding off method will set the limit of rounding for given unit of measure. The rounding off method can be maintained in SPRO > Material Managment>purchasing >order optimizing> Quantity optimizing and allowed logistic unit of measure-->Unit of measure rounding rules.
Hope this will help u.

MRP Run For Credit Blocked Sales Orders

Hi
Does any one know how to prevent the generation of planned orders for Sales orders which
have been credit blocked. At the moment the reservation is still visible on MD04 and is therefore
planned during the MRP run. As a result manufacturing continues for these sales orders.

As far as credit block is concern; what it means is that delivery will not be done for this customer via VL01N.
This means if you have blocked this customer in FD32; no delivery to be done
It may not be linked with MRP calculation b'cos it comes into picture while doing delivery & not during planning

Firm scheduling agreement with MRP

Hi gurus,
We are maintaining scheduling agrements in ME38 manually. system shows firm schedule lines in md04 screen. When we run MRP system does not consider or minus stocks and create planned order equals to the requirements. we need this scenario in this way that when we run MRP so system should minus stock if it finds schedule agreements, PO etc.
Please suggest.
Regards
Majid Ali Khan.

Hi Majid,
As per stanrd sap mrp process , system has to consider the current stock level/ available procureemnt prosposals in mrp calculation.
Are you using gross planning (PS 11)? what is the mrp type for the material.

Requirement in MRP even after Sales order completely delivered/cleared

I see a sales order in md04 even after that order is already cleared completely delivered
I have checked the pGI quantity in order and document flow. everything matches and status is completed/cleared.
I also ran SDRQCR21 in se38 with data transfer checked. Still I am unable to delete that fake order from md04.
any help is appreciated.

Hello ,
Have you checked & followed all instructions in SAP note 207942.
"Generally you can solve these problems with report SDRQCR21from Note 25444. If not, these kinds of problems must be processed further in SD-BF-AC.
However, often the problem is also caused by the fact that
no requirements are generated at first or the generated requirements are only displayed but are not included in MRP calculation
or vice versa
due to the Customizing settings requirements are stored although this is not wanted from the business view. "
This is a release independent SAP note. so it applies to ECC6.0 as well.
Hope this helps you resolve your issue.
Thanks,
Ram

Best practices for approval of MRP generated PRs

Hi, all. I'd very much like to route our MRP generated purchase requisitions directly to the Purchasing department without the need for additional approvals, regardless of $ amount.
PRs not generated by MRP (manual) will still need to pass through a release strategy.
What is the standard industry practice for processing MRP generated PRs?
What have you seen?
Thanks in advance.
Sarah

Hi,
Well i haven't come across a situation which requires an approval of MRP generated PR's.
If the process of loading demands is controlled, then the output from MRP is by default controlled, unless there is some specific enhancements put in MRP calculation which does a change.
So if there is no such enahancements, then i do not see a need for the same.
So from a good practise perspective, i would look at controlling the demand & the manner in which it is entered into the system.

Vivek

Order proposal in MRP

Hello experts,
when I run MRP, I want ONLY ONE PLANNED ORDER for the material for a fixed quantity. Even though the shortfall is more, I want only one planned order for a fixed quantity.
I have tried FX. But I get multiple order proposals with a constant quantity.
Kindly help.
Regards
Tom

Hi,
I don't think your requirement can be solved in standard SAP. As I checked lot sizing procedures I saw that SAP concept is to avoid material shortage - your requirement is against this.
http://help.sap.com/erp2005_ehp_04/helpdata/EN/fe/819b9f643b11d3b4e40004ac160649/frameset.htm
If you want to get one planned orders, you should use period lot sizing procedure - in this case you would get only one for the specified period. But at the same time to get fixed quantity makes no sense since requirement may vary from time to time...
Fixed lot size can't help as described by you because you get several PldOrd with fixed lot size if the requirements are higher than the fixed lot size defined by you.
You can only terminate the planning run if more than one procurement propsal should generated by the system (MRP > Planning > MRP Calculation > Define Error Processing in the Planning Run).
You can specify a threshold value for the maximum number of order proposals for the fixed lot size in Customizing for MRP in the IMG activity Define error processing in the planning run. If this value is exceeded, that is, if too many procurement proposals are created for a date and for a material, the material is provided with a termination message.
Rounding down would be the best if it was possible to round down the quantity.
Well, I have doubts whether you can solve this in standard system.
(Maybe if you describe the business process experts can suggest you a workaround or something.)
Regards,
Csaba
