I need to allocate low-level code to a material while creating in mm01..

hi experts,
In the material master record, each material is allocated one low-level code (field L.Lvl Code) which is determined by the bill of material (BOM) management program.I couldnt find this field in any of the tabs while creating the master record.So can u plz help me out to find this.
Thanks in advance..

Ramesh,
You cannot create an LL code entry in MM01. The purpose of MM01 is to create Material masters. LL code is managed by the system, automatically, during BOM maintenance. SAP does not give the users the ability to edit LL codes.
It is unwise to attempt to change LL codes. Improper entries in this field could lead to MRP results that will not meet your business requirements. You should generally let SAP automatically manage this data for you.
In the case where you believe you have an incorrect LL code, SAP does have some OSS notes that apply. Start with [544489|https://service.sap.com/sap/support/notes/544489].

Error Msg while BOM creation - Maximum low-level code 999 reached

Dear Expert,
After uploading the BOM (T-code: CS01) of material XXXXXXX in XXXX plant, error message through express message is coming regarding maximum low-level code 999 and the BOM is automatically getting deleted.
Error Info... Maximum low-level code 999 reached
Thanks & Rgds,

Is by any chance this BOM recursive?
If so, you need to allow recursiveness specifically.

Issue in determining Low level codes

Hi Gurus,
We are having an issue running heuristics when running along with Temporary low level codes. We are in SCM 7.0 environment.
The SNP Heuristics jobs are failing with this message "Low-level code
not available for product XXXXXXX at location XXXX
Job cancelled after system exception ERROR_MESSAGE"
Also, the message in the job log for the product in was flagged for deletion and I am not too sure why is this being picked up for processing and then failing?
I tried using SDP relevance as '1' for the product flagged for deletion for testing purposes and then the program is not considering this SKU, but stopping at another SKU and also that SKU is flagged for deletion. But the flip side of using SDP relevance is that that setting is at global level andmay have issues where the SKU is active.
I have couple questions:
1) Is there a way for the program to skip the code which has an error and move forward instead of failing the job? and provide a spool with error codes.Also, to provide the LLC number for all the correct SKU's instead of failing at that point and not generating the LLC's?
2) Why is the program also considering the codes which are flagged for deletion which should not be the case?
Also, I tried another way of maintaining the codes in thevariant which are not flagged for deletion and tried running heuristics in the background but failed at a point and it gave a message stating Low-level code not available for product XXXXXXX at location XXXX, Job cancelled after system exception ERROR_MESSAGE
But the product which was displayed in the job log is an active SKU. I am not too sure why the job failed with this error?
I tried running that individual SKU in the background including the temporary determination of LLC, it was successful. I am not too sure why it failed when it was a part of selection?
Any suggestions, would really help us a lot.
Thanks and regards,
Murali

Hi Datta - Thanks for the replies. I was able to have a workaround by using selection profiles excluding the Procurement type 'P' and it worked.
At our client, whenever a product is made 'non-X0' in ECC, procurement type is set to 'P' and by excluding that piece in the variant I was able to continue with my processing.
But still, don't you think the products which are flagged for deletion shouldn't be picked up heuristics?
Thanks and regards,
Murali

Low level code

hi
while configuring SNP planning run -SAPAPO/SNP01 screen under object selection >manual selection i could see planning version, product, location and low-level code....
1. what is the significance of this parameter low level code ?
2. how it reacts to the planning run ?
my guess is that it takes into account all the tail end level of the BOM that belongs to the product ..but am not sure ..since it is 000/production server i dont want to experiment
Please help me understand the science behind low level code,can you please suggest an easy to understand link or material
thanks

Hi Rahul,
The low level code the position of a particular location product in a supply chain. SNP heuristics use it to determine the correct planning sequence. This is particular important if you are running "Location Heuristics" and putting the location products in the selection and want system to plan for only those location products.
The system will use the low level code to determine which location product to plan first and then move to the next one and so on.
You can refer the following links for further explanation.
The Level of BOM Planning in the SNP Heuristic and Low Level Codes - SAP Planning

Low level codes

How are low level codes define in bom,we know that systems plans 000 first then 001 & so on.
for example fert will have 000 , halb 001 , & roh 002 it is like this or vice versa.
but what i think system plans first for roh , than halb then fert , what u say ?
or how can u define low level code how it works ?
are you posting these things or not
plz explain in detail ....experts
Regards
SF

Hi Safraz,
Your intially statement is right
i think system plans first for roh , than halb then fert , what u say ?
Here the system doesn plan from below,because the requirement comes for the top level not for the dependendent levels
For ex -sale order or PIR (any reqmnt for tht matter) is created at the finished level product
There by system xplodes the BOM & plns for the dependent requirement
Regaring the low level code calculation check the below link for better understanding

Low-level code MRP

Dear gurus,
i find in the material master (MM02 and in the table MARA) the parameter "Low-level code" = 000 , how use this parameter ?
When this value is write? At saving of Bom? Is a setup of customizing for value possible?
Thanks a lot

Hi
Pl go thru the following may be useful
The lowest level that a material appears in any product structure of the
company. The low-level code controls the sequence in which the material
is planned in an MRP run: First the materials with low-level code 0 are
planned, then the materials with low-level code 1, and so on. The lower
the low-level code, the higher the number that is assigned to the
material.
The level that is set in the material master record represents the level
at which the material will be planned. This means that the material will
only be planned once all assemblies in which it occurs have been planned
and exploded.
The low-level code is set internally in the material master record when
the BOM is maintained.
When you create a bom item for a assemblyparts ,the item's low-level code will equal (assemblyparts's low-level code + 1),but if (assemblyparts's low-level code + 1) < bom item then the bom item's low-level code not changed

SNP - Issue with PDS as source of supply in low-level code run

Hi All:
I have a bunch of PDS that is giving me the following message when the SNP Low-level code is run:
''Invalid source 00000010382991380SLT1 S is not considered for low-level code calculation. The source of suppy 00000010382991380SLT1 S is available actively in the Supply Chain Model. The location product for which the source of supply is intended, does not exist, however, or is no longer assigned to the model. The source of supply is therefore invalid. ''
I tried all of the following but still did not get to work
1. Made sure that FG and all the active component of one FG and the location and the PDS were in an active model.
2. Made sure that there was one production version and hence one PDS
3. Intialiazed the Planning area with the version
But still would not generate the low level code for the product location. Can some one throw share some insight and help pl?
Thanks
Ryan

Could you please check whether in the Product Master, Procurement tab, the Procurement Type is set as "P - external procurement planning"? If yes, then that's the reason as the Low-Level Code is only calculated for Products that are to be planned in APO. In this case, change procurement type to X or E and it should work.

Tiago

Unable to View low level items for Phantom Assembly - Order created in APO

Hi All,
I am unable to view the sub items when I create planned orders in APO and production orders in ECC. But when the order for the same material is created in ECC, I can see all the sub items. I see that this issue is only for Phantom Assemblies.
And I cannot say that all the items in the Phantom do not appear, actually some of them do appear in BOM explosion.
For example:
Pld Ord is created for A in APO
Prd Ord for A is created in ECC
A has B, C and F as requirements
and B is phantom
B has D and F as requirements
Then my BOM explosion shows
..1 B
..2 D
..1 C
..2 D
..2 E
..1 F (This only gives the quantity required to make A)
But it should also list how much of F (..2 F) is required to make B.
Where as it comes up in ECC.
Do I need to change the material settings for Phantom or is it just the UOM that is creating an issue?

Saving of different Material code in the system while Creating material

Hi,
Anyone can help me in following .
While creating material number, there should be some User exit which is going to change the logic for saving of material number in the system.
Example:
Division and material Group should be added into the predefined number range. Number range defined for raw material is 100000 to 199999. If division is 1A, and Material group is M01. The first number generated by system is 100000 , where as during saving into the table NUMBER SHOULD BE saved as 1AM01100000 & we must be able to work on the new number.
If any query pl .revert.
MG.

Hi manish,
This is possible using enhancement.
Use the User Exit MGA00001
and code the below like :
cmara-matnr = cmara-matnr+7(11).
CONCATENATE cmara-matkl cmara-spart cmara-matnr into cmara-matnr.
set PARAMETER ID 'MAT' field cmara-matnr.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
EXPORTING
input = cmara-matnr
IMPORTING
OUTPUT = cmara-matnr
Hope it will solve your problem.

Need to change forecast data thru planning book + doubt while creating POS

hi friends,
my application creates forecast data for following.
product , location start date , end date.
i need to put this data into APO(DP).
i know i can do it using BAPI CHANGEKEYFIGUREVALUE2 of Planning Book APs
my doubt is while create a Plng Object store, what fileds do i take as charachteristics which match these, please reply if have some clue

Hi Rohit,
I believe i misunderstood your first post. I had given the BAPI parameters that you need to fill up for the given business requirements you have mentioned. I realized you were asking about the POS.
Answer to Q1: You can not place time characteristics in the POS. You will define the "time characteristics" in your Planning Area by specifying a relevant storage bucket profile.
Answer to Q2: You dont need to add time characteristics in the POS.
Answer to Q3: 9AVERSION is not included in the POS. However, when you use BAPIs BAPI_PBSRVAPS_GETDETAIL and BAPI_PBSRVAPS_CHANGEKEYFIGVAL to read/write data from/to the planning area you need to supply a selection for the planning version (9AVERSION).
Hope this helps.

Low level codes (LLC codes) cannot be determined

we are facing an error of LLC codes cannot be determined , due to cycles in model for a certain transportation lane
problem is we faced same issue for the same LOcation transportation lane earlier for the same product, for which we blocked the product specific transporation lane between the concerned locations.
Can any one point out what could be the reasons for this error repetition.( FOR SAME LOCATIONS and PRODUCT )

Hi,
Check whether there is any cyclic transportation lanes.
For the LLC determination there cannot be any cycles in the transportation lanes.
That is why system is unable to determine the LLC.
Ex A-B and B-A

T410s - Need advice on Low Level format of Lenovo SSD and reinstall on Win7

I'm new to SSD formatting, and wanted to know if anyone has done a clean install on a Lenovo SSD. I have used DBAN in the past on my HHD based systems, but I've read that SSD's need to be formatted differently. I have a T410s 2901CTO that I want to reconfigure.
I would like to nuke the entire factory 128G SSD, repartition, format and install a clean Win7 OS.
Any help, links, etc, are greatly appreciated

BigBlack,
Actually ThinkPad BIOS prevents issuing the ATA Secure Erase command from software, after POST exits. This is for security reasons. That's why SSD erase can only be done from within BIOS itself. So your link would not work on ThinkPad, to do a Secure Erase on SSD.
T400/T410 generation use this method: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-68369
T420 and later user this method: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS019026
Traditional disk-wiping methods like DBAN aren't optimal for SSDs due to the way that SSD firmware maps writes to NAND in unpredictable ways. So even after a DBAN wipe, your data may still remain on the SSD, and all you've done is generate wear on the drive.

TDMS Low level file functions and Saving Front Panel image

Am using TDMS low level file functions to save while also plotting data in my data acquisition programme. However, I also want to programmatically be saving the front panel image on every run of my data acquisition. I have coded all other aspects, except the behavior of functionality of saving the front panel image on every successive runs of the application. Unfortunately, I just have no idea on how to code this aspect on LabVIEW, and all effort to search for example codes on so far have not been successful.
I would appreciate any useful hints or steps from anyone for me to follow, in order to accomplish this behavior, and that is being able to programmatically save my front panel images while using TDMS low level file functions in my File IO system of my application.
Thanks in advance.

Tax code not displaying in me2j - Need Report for PO tax codes

Dear Guru's,
For Trading materials, while creating PO, we are inserting Tax codes in "Invoicing Tab". But the same(TAX CODE) is not displaying in ME2J report.
But For service materials, we are entering tax codes in the "Services Tab" and it is displaying in the report ME2J.
Kindly tell me a report where we can see the taxcodes for PO.
Regards,

Sir,
I did that already, but no code is displaying in that "Tax code Column" for Trading materials.
But tax code has been entered while creating PO in "Invoicing Tab" as "V0" for example.. V0 is not displaying in ME2J Report.

Need help in copying Invoice date to lower level item in Sales order report

Hello Experts,
I am debugging into one Sales order report.I need little bit help.The report is displaying Invoice Date for
Sales order Billing documents for Higher item in Bill of Material Structures.But as per user requirement,
I am supposed to show the Invoice date for lower level items also.The field for Higher level item is 'UEPOS'.
I want to copy the Invoice date for Higher level item to lower level item. Can you please guide me in the logic?
Thanking you in anticipation.
Best Regards,
Harish

Hi BreakPoint,
Thanks for the information.
I have applied the same way but it is showing only lower line items now.
Invoice dates for Higher level items are not there.
I am pasting the code here which I have applied.
Then you can give me more guidence.
This is to be done only for 'ZREP' sales orders.
if w_vbak-auart EQ 'ZREP' and w_vbak-uepos is not INITIAL.
                      read table t_final into w_final_ZREP with key vbeln = w_vbak-vbeln
                                                                    posnr = w_vbak-uepos.
                         w_final-erdat_i = w_final_ZREP-erdat_i.
                         else.
                if w_vbak-auart EQ 'ZREP' and w_vbak-uepos is INITIAL.
                  w_final-erdat_i = w_invdate.
                endif.
                endif.
Can you please sugest me changes here?
Best Regards,
Harish
