Collective Orders:- Child Component Lot Size

Hi Experts, please look at my scenario in collective orders
1. BOM: 1 header = 1 Component A
2. Component Lot Size: FX; Fixed qty = 10
Order Qty = 100
So, I expect 10 child orders to be created; But I get only one child order for 100.
Can anyone suggest how to resolve this?

Hi Jack
If you put 2 ( collective order ) in MRP 4 view of header materiel. The dependent requirements to that header will behave as per the setting of header material.
It will try to cumulate the quantities of the same order start date and try to put one plan order.
For Ex
You have four header material X, X1, X2, X3 in each of them if you put 2 ( collective order ) in MRP 4 view. The item material is Y. And this Y is item for all the 4 header material in BOM.
And if you pass 4 different demand of each quantity 100 on same date 15/04/08.
It will create 4 Plan order Each one for X, X1, X2, X3 for header and only one plan order for Y for 400 qty. That is the concept of collective order.
If you want to use FX remove 2 in header material.
Hope this will clear your doubt

Lot size

The parents material lot size is fixed lot size , child component lot size is 2 week lot size. ( ie. 2 week = 10 Days ).
question:
If the demand for parent material in month,after MRP run the dependent requirement for child component also getting generate only one planned order.
What are the possibilities if the parent demand in month, child requirement is needed in weekly basis .Any chance to get the child requirement in weekly by changing lot size or any other possibilities.

Hi,
Thanks for your answer. if we change the lot size for dependent material to weekly , biweekly or fixed etc....
The dependent req. will generate according to the lot size that is absolutely correct. but planned order or purchase req. will create according to the parent demand (ie .Adding of dependant req. what ever falling with in the lot size period and for that quantity planned order or purchase req. is getting created )
Actually my requirement is for the each dependent requirement one planned order should get generate .

Maximium lot size is 200 in MRP1 view.I have purchase order which 400 qty

Maximium lot size is 200 in MRP1 view.I have purchase order which 400 qty , but my system is allowing to pick 400 qty, can you please say wat may be the reason
regards
sakthi

Hello,
As others others experts are saying your maximum lot size will only work for MRP run not for manual created PR.
The system takes this value into account during the automatic lot size calculation for planned orders and production orders. The lot size of the individual orders cannot exceed this value

Maximum lot size - create order manually

Hi Experts,
we are in the implementation phase of the project (PPDS) and need your help.
For the products we have the data of Maximum Lot Size, that is a constrain for the process. But when we execute manual adjustments/creation of the planned orders, this maximum lot size is not respected, because for the manual orders is used the heuristic SAP_PP_001 Change Order Manually.
We need to consider the maximum lot size even for manual adjustments/creation.
Does anyone knows a way to consider the maximum lot size when create orders manually?
Thanks in advance
Thiago Cyrillo

Hi Hans,
If as per the requirement you want the system to take into account the period of 63 days reqirement , then as my experience the lot size field should be changed from the daily lot size .......or else the setting is quite redundant in nature........in accordance to your business requirement.
Check for the period lot sizing for detail information..........incase you have any query then let me know ......
Please reward points if it is helpful.........
Thanks

Lot size dependent / independent

Hi, please advise when the system uses this lot size times data in mrp4 view? Where we need to specify that whether lot size dependent or independent need to select? When the system uses this data and when the system uses the planned delivery days and in-house production days which is in mrp2? Pls advise.

Dear,
Planned Delivery Time use for external procurement Like raw materials.
In-house production time use for in house manufacture materials like HELB and FERT.
In-house production time is independent of the order quantity.
Lot size depnendent timing calculate from the routing. It is calculated byadding the lead times of all operations, the float before production, and the float after production.
You schedule the routing for a base qty The in the scheduling results screen click the button" scheduling results"
You will get the results screen in days.
In that screen at the botton there is abutton update material master.
After this go to CA96 There update the material master.
Please refer this link,

MRP lot size?

HI All,
Guys i configured M.R.P Type and M.R.P Controller, but I am unable to understand the M.R.P Lot size?
while i am creating a material in mm01 lot size is not allowing me to chose any other option except EX-Lot for Lot Order quantity.. could any one suggest why is it so..?
Thanks and Regards,
Chinta

Do you mean you can see all the lot sizes but system is not allowing to select or you can see only EX? Because only "EX" lot size doesnt require further data. But if you select any other lot sizes like "FX - fixed lot", you also need to enter the fixed lot size value in fixed value. if you are dealing with CBP, below are the important lot sized to use.
Lot-for-Lot Order Quantity
Fixed Lot Size

Minimum Lot Size Ignored

Hello All,
To replicate scenario, I have created new material with minimum lot size 10 pcs and created independent requirement (LSF) and then created scheduling agreement.
Independent requirements as 8 pc for every day.
Now when I run the MRP and check in MD04, for the last requirement, planned order was raised for just 9 pcs, ignoring minimum order qty/minimum lot size functionality.
Just for information, Lot size -EX, MRP type PD, Strategy group 10 (though these factor doesnot influence).
Any more settings/customizing required?
BR,
Krishna

Dear Krishna,
I guess you must have activated the check box for Last Lot Exact for the Lot size - EX in T.code OMI4.
If so means remove this and then check with new requirements and MRP run with planning mode - 3.

Min max lot size time based for use with SNP and PPDS

Hi all, Is there anyway to set up time based min and max lot sizes? ie we want to have a Max lot size which is small for use with the first 3 months of our plan which starts life in SNP and then converts to PPDS and into blocks for block planning, but months 4 to 36 we want to leave as large max lot sizes as there is no need to have the small max lot sizes for the different horizon.
As far as I can see there is only a material/plant lot size and Max lot size and no way to have a different setting in a different time period.
Thanks
j

Hi John,
As you know, in the product master, the lot size maintenance is time-independent, so that obviously can not be used for your scenario. As per my understanding, to meet this using standard functionality, you can maintain multiple product specific t-lanes (for STRs) and PDSs (planned orders) with required lot size ranges and validity dates (for short or long term horizon). But, again since the validity of t-lanes and PDSs will not be automatically rolling forward so the updating the validities will be a challenge.
The other option could be to enhance the heuristic functionality at lot size selection step while creating order.

Umesh

Lot for lot(EX) with minimum lot size

Hi Experts,
Is it possible to have Ex with minimum lot size. I have a situation where an FG cannot be produced over a certain qty but can be produced in any numbers beyond that. Please explain.
Regards,
Sachin

Hi,
You can use Lot size key EX- lot for Lot order and Minimum lot size as per the requirement. If the lot size is smaller than the Minimum lot size qty procurement proposals will be created for the minimum lot size quantity.
Hope it resolve your issue. Kindly revert for further clarification.
thanks and regards

How to perform Data Collection on single SFC with QTY = 1 with material lot size 1?

Dear experts,
We are working with SFC qty>1 on a relaxed routing. At a given operation we want to collect the data on single quantity; i.e. SFC qty on that operation, where the collection will happen, will be 1.The corresponding material lot size is for ex 10. The operator must be able to collect data on SFC with qty=1 multiple times until the quantities will be consumed. He must be also able to collect other values on the remaining quantities on the same operation with the same DC group or other DC groups. How many times the data must be collected is dependent on the shop order build quantity. The data may be collected several time but not more than the build qty. In other words some specific data will be collected on a qty of a product while others will be collected against remaining quantity. The data collection must be also done in a serialized manner.
Here's what we have set up so far:
1) 3 DC groups, each DC group has 3 data fields.
2) Each data field has the following restrictions: Required Data Entries = 0 and Optional Data Entries = 1
3) All DC groups are attached on the same combination of operation\material\routing
4) we are using relaxed routing
Process description:
The operator must be able to collect any data field on single product. For that he will enter the operation where the data collect are attached, he will enter the SFC with qty=1 then he will run the data collection after selecting the appropriate DC Group and entering the needed information. The operator will complete the SFC with qty=1.
The operator will pick the next product, select the same SFC and enter qty 1 and collect other value against this product.
Problem is:
Once the first collection is done on a given SFC with entered qty=1, the system is not allowing the operator to do further collects on the same SFC with qty=1 or any other quantity. He cannot select any DC group from the DC group list. We tried also with the table selection menu on the DC Group list but nothing can be selected.
So we tried to play around with the DC group definitions as follows:
A) we set Required Data Entries = 0 and Optional Data Entries = 10. Still the operator was not able to select any DC group after collecting data the first time. We tried to reopen the pod and list again. But we get the same blocking behavior.
B) we set Required Data Entries = 10 and Optional Data Entries = 1. The operator was able to select the DC group after collecting data the first time. BUT operator must enter the data fields 10 times on one SFC quantity, which is not what we want. Besides again he cannot collect other information on remaining quantities on the same operation.
C) There's an option to serialize the SFC before reaching the operation where the collection is happening, then merging ofter complete. Automation is needed here; hence customization. We are highly avoiding customization now, since we expect the data collect to work well on single quantities even when the main SFC has qty>1
Questions:
1) Are we missing any kind of further configuration\setup?
2) Or the current system design does not allow collecting data on single quantities of an SFC which main quantity is greater than 1?
3) Looking at this link Approaches to Collection of Data - SAP Manufacturing Execution (SAP ME) - SAP Library, there's nothing mentioned about same SFC number with multiple quantities!!!
We are using SAP ME 15.0.3.0.
Thanks in advance for your help
Ali

Ali
to collect data for the same SFC multiple times, your system rule "Allow Multiple Data Collection" needs to be set to true for the site.

Material set to lot size TB not summing up orders when covering

Hello all. I'd appreciate any input on this problem we're seeing.
We have a material that has lot size set to "TB" (Daily lot size). This leads us to expect that demands on this material will be covered by purchase orders summing up all the demands for this day.
For instance we currently have 10 orders for 11. sep in different quantities from 1 to 3. Since the material is set to lot size TB we would expect to see a purchase order for 19 pieces which is the total.
But instead we get a bunch of small purchase orders, the system doesn't appear to sum up as expected.
Has anyone any ideas about why this may be so?
Regards
Simon Pedersen

Thanks for the answers so far, It's not letting us make much progress though.
The material is a trading good (HAWA). It has no BOM. The Collective indicator on MRP4 is not maintained (as far as i know it should not be since there are no dependent requirements involved). The demand is triggered by Sales Orders.
The purchase requisitions get generated by the MRP run based on these sales orders. That is what we don't understand, since the material is set to TB the MRP should make a single bigger order instead of many small ones.

Lot size calculation for Purchase order

Hi all,
I want to purchase Labels which comes in lot qty such as in lot of 100,200 etc.
For that particular items i want to do mandatory qty lot size in PO when buyers places the purchase order.
Can anybody tell me How i can map that lot size for the particular item.
Regards,
Anant

Hi,
You can done it with change Material Master.
Enter MM02 t-code, enter your material code and select MRP1 view.
Here maintain Rounding value as 100 in material master.
After when your create purchase order system put quantity as 100, 200, 300 etc.

Fixed lot size key has no effect on planned orders generated for VC PIRu2019s

Hello gurus,
does anyone have an idea why the fixed lot size key is not having an effect on the planned orders that are generated for the Planned Independent Requirements (PIR) for MTO configurable materials. My client is using planning strategy 56.
I have copied & customized the Fixed lot size key FX to suit the MTO production (u201CLot size as in short-term periodu201D activated) that works nicely even with configurable materials when a planned order is generated for a sales order. But the planned orders in the preplanning segment, i.e. that were generated for PIR's, are still created equally to the PIR quantity.
Is this behavior an error or an SAP feature? Though, I have reviewed the OSS Note 437098 that might be related to this. Can anyone tell me if it is related to this issue?
Regards,
Mikko

Got the answer fro SAP:
Please consider the following note, which provides the explanation about this behavior of the lot-size, when VSE requirements are used:
125498 - MRP/Docu: Planning segment and lot-for-lot order quantity
The following section of the note describes your scenario in detail:
"The planned independent requirements for a material are in a separate
planning segment (planning strategy planning without final assembly,
requirements type VSE, VSEV).
You enter a rounding value or a rounding profile or an lot size that is
not exact in the material master.
Material Requirements Planning:
In Material Requirements Planning, planned orders are generated for the
planned independent requirements. The lot size settings (such as fixed
lot size or minimum lot size) are also not taken into account."

I am executing MRP on 7.04.11
As shown above the, can you please explain why the planned order is on Wed 12th and it covers 5 days requirement and similarly Tuesday 19th and covers 6 days.
I am not able to relate the relation between Planning calendar and Lot size procedure used. Also what would happen if I make planning calendar valid for two days in a week.
Thanks in advance
Rahul

Thanks dear
Yes you are right the Planning Calendar starts 18.4.11 and ends 24.4.11
Now as far as first planned order is concerned I thought it should be scheduled to start&end on Monday 11.04.11, rather it starts&ends on Tuesday 12.4.11. Also the actual coverage days goes up to 5 days even though its maintained for 3 days.
Similarly the second planned order also comes up on Tuesday 19.04.11 and covers 6 days (more than the setting and planning Calendar of only Monday)
On the whole this is confusing me on Lot size and Planning Calendar relation and how it impacts MRP. Can you please help me on this.
Also if you can throw some details on: how to restrict MRP to give planned order only on, say, Monday and Thursday, as only then it could be produced.
Thanks in advance
Rahul

Planned orders created with more than Maximum lot size??

Hi Gurus,
we have a lot size 'EX' with maximum lot size =480.
But, for the materail when we run MRP we found that aplanned order is created for 1000.
Please help me to find the root cause.
Thank you.
Naveen.

Hi
What is that material. If it fert and then yes system will create if you have mentioned max lot size.
Because the max lot size does not control prodcution, it only controls the procurement side
