Routing link to BOM alternative

Hi all,
In our current SAP solution (SAP R/2) each routing alternative stores a link to an associated Bill of Material alternative. We have noticed that in mySAP ERP the routing alternatives can store BOM alternatives in the Component Allocation tab, but if you look at the header table for routing PLKO there is a field for associated BOM alternative (STLAL). If we select a BOM alternative this field is still not populated.
Does anyone know where this link is stored? Does the new system assume that production versions are created to store this combination of Routing and BOM? We would appreciate the insight. Thanks!
Sincerely,
Justin

Hi Justin,
Suppose you have two BOMs ,alternative 1 & 2. T.code cs01
To change T.code cs02.
A routing is created for the header material. T.code ca01.
To change T.code ca02.
In the routing, if you click the component allocation tab, you can see both the alt BOMs. From here you can select the BOM you want & then save. All the material will be allocated to the first operation by default.
Reg. Prod version:
You can create eg version 1 Routing + Alt BOM1
version 2 Routing + Alt Bom2.
In the material master, mrp view 4 check the options Bom selection , here if you give as selection only by prod version, during prodn order creation, the system will inform that there are two prodn versions & which one to select. This selection of pron version can be made manual or automatic. Given in T.code opl8

BOM explosion where first BOM alternative has deletion flag

Hi,
I got the following very basic scenario:
One FERT material has two BOM alternatives (alternative 1 and 2). Both of them are valid in terms of date, status and lot size. When a production order is created by CO01 the system will pick automatically alternative 1 (which is ok for me). BUT if this BOM alternative 1 gets a deletion flag (on BOM alternative header) I would expect that the system would automatically pick alternative 2 (it is the "next" suitable alternative). But the systems says there is no valid BOM available.
Only if I really delete alternative 1 (so I cannot see it anymore in CS02), the system would pick alternative 2 (because it is now the really first one available - no version in front with only deletion flag). But in terms of documentation I cannot delete the alternatives.
Maybe somebody could explain that to me or had a similar problem...
BR and thanks in advance.
Christian

Hi Guys,
many thanks for your suggestions. Setting the status to inactive did the trick. Obviously the deletion flag is not enough at this point.
Just to clarify - production version of course would be an option but that did not work with the following:
I have 6 different routings for this FERT and the user has to choose when the production order is created. That works basically fine when the order is created with CO01 (popup for selection of production version based on MRP4 setting). BUT when a planned order is converted directly from MD04 into a production order the system would automatically pick production version 1 (no matter what setting in MRP4 view). If there are no production version the user would get at least a popup for choosing a routing. But this would maybe an additional thread in the forum
Thanks

Subcontracting & BOM alternative

Hi:
I need be able to select a BOM alternative into the Purchase Order for Subcontracting.
I mean, I've more than one option to make a material in subcontracting (different items for the same material) , then I'd like be able to make this decision.
Anybody can help me?
Regards
Omar Perea

hi
i think u need multiple BOm section i.e. alternate BOM,u can achive this using production versions
for this u have to do following
1. Define all the materials in your plant (subcontracting and packaging etc).
2. In the material master MRP 4 view there is one field in which you can mention that this material is not relevant to MRP planning, use this field for subcontracting material so that it will not be planned in MRP runs ( generally use this field for re-order point planning).
3. In the BOM for the subcontracting material put the special procurement key as Subcontracting and do not keep relevance for costing.
4. If you're using packaging material of your company and want to capture the cost of these materials in the subcontracting production order then put relevance for cost.
5. Define alternate BOMs for each customer.
6. Generally the routing will be the same but materials will change, define different prodcution versions for each alternate BOM and assign to the routing.
7. Define the activite types for packing and mixing in the work center and assign them to the cost center, use these for your routing.
8. Whenever you recive a sub-contracting order, use the relevant production version depending on the customer.

Error for open process order when BOM alternative is not found

Dear colleagues,
When I open process order. BOM alternative is selected according to the production version. But when BOM alternative is not found system gives only information message and I can open process order, I want to prevent open process order when there is no BOM alternative according to the production version. Because the Bom can be deleted after creation production version.
Thanks for your helping,

Hi,
U need to use an enhancement at the creation of order to check the active status of the bom and restricting the order creation when BOM status is inactive.
see whether following enhancement is useful for your scenario:
PPCO0006 Enhancement & EXIT_SAPLCOZF_003
Please confirm.

PO line item link with BOM

Hi guys ,
Actually I am looking for some info on this scenario. while creating PO for specific document type(ZPOG) and item category (L) , I need to modify the child material qty of the line item .
This is subcontract PO .
For example if I am creating PO for X material (which has y as a child ) , I need to modifiy the qty of Y .
actually there is one badi called ME_PROCESS_PO_CUST to handle the PO creation ,
But I am not able to find the link between that line item material and BOM material .
points rewarded if the question was answered .
Regards
Siva

Hi Ganesh ,
Thanks for your information . But my concern is it ( Child material qty ) should be rounded off while creating PO . not to be done manually .
For that purpoes only I am using that Badi , but I couldn't find the link between BOM material and PO line item material .

BOM Alternative Check on CS01 screen

Dear All,
Right now i need to implement a user exit for the BOM alternative in CS01 screen. For a particular BOM Usage we should not allow the user to create alternative other than '1'. So before getting the automatic alternative i need to implement the user exit/Badi for the checking on the alternative.
thanks,
rajesh.

Hi,
There is a standard customzing for alternative BOM in CS01...
SAP Customizing Implementation Guide --> Production --> Basic Data --> Bill of Material --> Control Data for Bills of Material --> Define Modification Parameters. If you tick the " Multiple BOM inactive" then nobody should be able to create other alternatives then 1.

Bom alternative item group

Hello Experts,
I have one issue in BOM alternative item group I have made the settings as below.
Material 1     AltItemGroup         01
                     Priority                                  1
                     Strategy             2 100% check
                   Usage prob.         100
Material 2     AltItemGroup                      01
                      Priority                                  2
                      Strategy             2 100% check
                      Usage prob.         100
For Material 1 required bill of material quantity is 65 MT
For Material 2 required bill of material quantity is 65 MT
Now I am creating the process order for quantity 1000 MT. When the material availability check done it proposing as below in process order.
Material 1 = 65 MT    (Available Stock 807.109 MT)
Material 2 = 0 MT      (Available Stock 5.850 MT)
And again Material 2 = 32.5 MT
My question is as per above settings and stock situation of the material it should propose only Material 1 = 65 MT. But here system is also proposing Material 2 = 32.5 MT. Can any one tell what I am doing wrong?
Any settings are missing or what will be output for the above settings.
Please explain in detail.
Thanks in Advance
Regards,
Ganesh

Hi Ganesh,
Pl. make the following settings:
Material 1 AltItemGroup 01
Priority 1
Strategy 2 100% check
Usage prob. 100
Material 2 AltItemGroup 01
Priority 2
Strategy 2 100% check
Usage prob. 0
The strategy 2 will automatically handle the situation when Material 1 is not available and 2 is available.
Pl. test & revert. It will work as per your requirements

SD-PP integration: BOM alternative

hello, friends. i wish to ask you about transfer of requirements from SD to PP.
when processing the sales order, the user can manually select the BOM alternative via a dialog box. in standard, BOM with usage 3 (universal) and 5 (SD) are supported.
i notice that after we run MRP, in the planned order the BOM usage is 1 and alternative is defaulted to the first in the order sequence. this is true if the BOM selection method in the material master MRP 4 view is either for production version or blank.
if the selection method is by key date, then the BOM in the planned order will be the first in sequence for alternatives by key date.
in variant configuration, the specific requirements are transferred. but for a simple BOM, in neither situation is the alternative selected in the sales order transferred. why is this so? are there missing settings?
hoping for your valued inputs.
many thanks.

Hi
In case of Variant configuration(VC) , the BOM Selection will be based on Dependencies assigned to the Components. In VC there is no alternative BOM Concept. There will be one Simple BOM called Super BOM which contain all the components which is required to make all the variants of K-mat.
In the sales order , the user will configure the requirements and based on the requirements selected in SO , the system will pick respective Components from Super BOM during MRP

Modem router link down in a small network when I connect any mac with OSX

With OS9 I have no problems at all the other machines are PCs, I try whith 2 diferent laptops, and 2 macmini and the internet connection throught a modem router link down inmediatly... and the modem try to connect many times automaticly, and connect for few minutes... after that being link down again... any ideas what the problem is? I think a protocol interference may cause this, but I don't know what really... thanks

Start by changing the wireless names to SMB compatible names.. ie short, no spaces and pure alphanumeric. Make sure the HP is in range of the router.
You can use the WPS setup via the utility main menu. There is no WPS button as such but apple has had to provide some way to handle this directly.

CProjects - Object Link to BOM

Hi,
I have a requirement to create an object link in cProjects. I have maintained the CS03 in the SPRO settings. While creating an object link from cProject and click on search button the system throws an error "Proxy Class(, method EXISTENCE_CHECK) for object type Bill of Material contains errors". Can some help in providing the procedure to create an Object link to BOM.

Hi Sasi,
Create a custom class ZCL_DPR_OLR3_XXX implementing the interface IF_DPR_OBL_PROXY
create another custom class ZCL_R3_OLR3_XXX implementing the interface IF_OLR3_PROXY
Create Structure with namespace ZOLR3_TS_XXX_INT_ID where XXX is the table name for this structure.
This is the internal id that is going be used in the configuration. This Structure is suppose to hold the key fields of the
object table(not all key fields is mandatory).
Create Structure with namespace ZOLR3_TS_XXX_SHLP where XXX is the table name of the object.
This is the searh help structure that is to be used in the configuration. This searchhelp structure needs to have the fields
that are supposed to be diplayed at the time of seach.
Create structure with namespace ZOLR3_TS_XXX_DESC where XXX is the table name.
This structure is required for the BOM description. The field in this structure should be available in the table XXX.
Then in the SPRO create the object link and assign the class accordingly.

Santosh.

L2 and L3 Routed Link between 2 COREs

Hi
What is the difference between L2 (Dot1q) and L3 Routed Link between 2 COREs in term of Functionality
thanks

Hello Ibrahim ,
I will try to explain ,
VLANs put tag on frames to ensure packet do not leave layer 2 broadcast domain and yet will reach to all ports part of that vlan ( as per tag ) .
Layer 3 SVIs on other hand provides layer 3 reachability for vlans and hosts inside layer 2 vlan . To achieve this all layer2 vlan host provide with related layer 3 SVIs ip address as gateway .
I hope you got it by now .

The BOM alternative 1,2

Hi,
We have created one BOM (alternative 1) with date (valid from10.01.2008) and 2 Months later we kept the same BOM and created (alternative 2) with date (valid from 10.03.2008). We will always (re)create the same BOM with new alternative every 2 Months.
Now we want to display the BOM (from the last valid from date) only when we give a date and not a alternative number (because in one year we will not remenber the alternative number.)
How can I customize the System so that it shows the right BOM through the date (valid from or the last valid from date). for exp. if I give 10.03.2008>Display only BOM(alternativ 2) and 17.03.2008>Display only BOM(alternativ 2) because it is the last valid from date
Thanks

Dear Dede,
Kindly read this and revert back what more you need.
1.When you create a BOM for a material (First Alternative) as on today using an ECN,then in the header of the BOM,the valid from
date will be 28.03.2008 & valid To Date will be 31.12.9999.
2.For its BOM components the valid from date will be 28.03.2008 & valid To Date will be 31.12.9999.
3.If create a Change that's valid from tomorrow(29.03.2008),and using this if i'm changing the First Alternative BOM's components say
i'm deleting one component and saving the datas.
4.If i go in display mode of the BOM removing the valid from & To date in the input screen,then for the deleted item or component,the
valid from date will be 28.03.2008 & valid to date will be 29.03.2008.But in the header of the BOm,there wont be any change,the valid
from date will be 28.03.2008 & valid to date will be 31.12.9999.
5.Now if I decide to delete the entire BOM(alternative 01) on 05.04.2008,then i create an ECN that's valid from 05.04.2008,and using
this,I go in Change mode and then from the top menu,BOm Material --->Delete,and save.
6.Now go in display mode of the BOM and check in the header of the BOM,there now you can see the valid from date will be
28.03.2008 & valid to date will be 05.04.2008.
So this valid to date of the BOM header will be changed,only if the entire BOM is deleted.
I hope the above explanation will clear all your doubts.
Reward points if satisfied with the answer and close this thread.

Create BOM alternative via BAPI

How can we create a BOM alternative via BAPI?
I now use CSAP_MAT_BOM_MAINTAIN but then I get the following error:
BOM already exists for 1234 W041 9
I do not want to use batch input.
Kind regards,

Hi,
U can use the following BAPI'S
BAPI_MATERIAL_BOM_GROUP_CREAT
BAPI_MAT_BOM_EXISTENCE_CHECK
i hope they solve your purpose!!

Closet - core routed link. What to do with VLAN1.

I am connecting closets to core over routed links, what do I do with VLAN1? Right now it is enabled with no IP address. Do I do a shut? Leave it up and give it an addres with a 255.255.255.255 mask? Everything seems to be working except for NTP which may not be related.

For security reasons I would disable vlan1, this is Cisco's default vlan. I still would suggest setting up a vlan for management purposes (vlan10 or similar) and give it an IP address so you can remotley manage this device.

Hi experts,
In standard SAP we have a provision to write BOM alternative text like the same way I need another BOM Alternative text1 to be included is there any way to do this. and also it should be displayed when you go to item overview 9I.e. new field to be created and it should capture the data from BOM alternative Text1. Is there will be any exit for this.
Thanks in advance
