Clarification on WLC "Best Practises"

Good morning guys,
I have been working on my organizations Wifi infrastructure and have had general success. However, there's always more than one way to skin a cat. The one right way and the half dozen half-assed ways! lol
My question is based on the following scenario:
I have my WLC and AP's all on a VLAN tied to my management interface.
I have clients associating with those AP's and the clients are being handed IP's in that same management VLAN.
I want to now create a guest WLAN that will send all the guest clients to the internet, bypassing the production network.
Based on this, is it better to have the WLC and Access Points which are on the management interface on a seperate vlan than what I have my clients connecting on?
Currently, everything's on vlan 130. The controller, the AP's and any clients. They're all on the same subnet/vlan 130.
So now, when I want to setup that new guest WLAN and have that on our "internet only" vlan, which is vlan 150 for example, how are they supposed to get an IP address issued when the AP's are connected to the POE switch and on access ports assigned to VLAN 130?
Everything's working great right now for the production WiFi.. but adding this new guest WLAN and having it use the same AP's is gonna be a challenge.
I don't think I'm going about this correctly. Can I get some direction please?
Thanks in advance.
Mike

Steve, you're easilly becoming my favorite member on this community!
Okay, so for medium sized org, I don't want the production WLAN linked to the management interface. That's an easy enough change. Thanks for the clarification.
As for the guest WLAN, I created an interface specially for the guest WLAN, assigned it to my "IE only" vlan and gave it an ip on that vlan. But the question remains, if the AP's are connected on switchports that are assigned to one vlan, can I expect that when a guest connects to a WLAN being advertised by that AP, that it will be able to reach the DHCP server for the "IE only" vlan?
Sorry if this sounds like a stupid question... sometimes the hamster falls off the little wheel.

Any best practise to archive PO's which does not have corresponding invoice

Hello,
As part of initial implementation and conversion, We have a lot of PO's / LTA created but their corresponding invoices were never converted into SAP from legacy system. SAP archiving program tags those as not business complete as the invoice qty does not match with po qty (there are no invoices to start with). Just flagging 'delivery complete and final confirmation' of PO does not help. Anybody ran into similar situation and how did they resolve it? I am reluctant to enhance standard SAP archiving program to bypass those checks and that is my only last option. Any SAP recommended Note / best practise etc would help.
Satyajit Deb

Where is the invoice posted?
was the invoice posted in the legacy system?
Clearance of GR/IR account with MR11 will usually close such POs.

When granting a user or a role access to a group of pages, it is best practise to grant that access to what type of file or component?

My question is same while granting user or role in the application, what is the best practise? How to decide the level of applying role to pagedef's, xml files, or some other file that i have missed out.

As for my concern I would go for page definition files.

Best practise in SAP BW master data management and transport

Hi sap bw gurus,
I like to know what is the best practise in sap bw master data transport. For example, if I updated my attributes in development, what are the 'required only' bw objects should I transport?
Appreciate advice.
Thank you,
Eric

Hi Vishnu,
Thanks for the reply but that answer may be suitable if I'm implementing a new BW system. What I'm looking for is more on daily operational maintenance and transport (a BW systems that has gone live awhile).

What is the best practise to provide a text file for a Java class in a OSGi bundle in CQ?

This is probably a very basic question so please bear with me.
What is the best way to provide a .txt file to be read by a Java class in a OSGi bundle in CQ 5.5?
I have been able to read a file called "test.txt" that I put in a structure like this /src/resources/<any-sub-folder>/test.txt from my java class at /src/main/java/com/test/mytest/Test.java using the bundle's getResource and getEntry calls but I was not able to use the context.getDataFile. How is this getDataFile method call to be used?
And what if I want to read the file located in another bundle, is it possible? or can I add the file to some repository and then access it - but I am not clear how to do this.
And I would also like to know what is the best practise if I need to provide a large data set in a flat file to be read by a Java class in CQ5.
Please provide detailed steps or point me to a how to guide or other helpful resources as I am a novice.
Thank you in advance for your time and help.
VS

As you can read in the OSGi Core specification (section 4.5.2), the getDataFile() method is to read/write a file in the bundle's private persistent area. It cannot be used to read files contained in the bundle. The issue Sham mentions refers to a version of Felix which is not used in CQ.
The methods you mentioned (getResource and getEntry) are appropriate for reading files contained in a bundle.
Reading a file from the repository is done using the JCR API. You can see a blueprint for how to do this by looking at the readFile method in http://svn.apache.org/repos/asf/jackrabbit/tags/2.4.0/jackrabbit-jcr-commons/src/main/java /org/apache/jackrabbit/commons/JcrUtils.java. Unfortunately, this method is not currently usable as it was declared incorrectly (should be a static method, but is an instance method).

Advice or best practise information about 1 or 2 clients in SAP R/3 DEV

I'm searching for advice or best practise information about clients in a SAP R/3 development system.
Reason for this is that we are up to refresh our SAP R/3 development system and up to now we have two clients on it:
- One customizing/development client without master data, transaction data et cetera
- One local test client with master data, transaction data and so on
One of our developers suggested to only have one client on development, where we could customize, program and test. So that client would be with master data, transaction data et cetera.
What would be your advice or what would be best practise for the development system: 1 client (with data) or 2 clients (one clean customizing and one with data). And what are the most important reasons to do it so.
Maybe there is already some good (SAP) information about this specific subject, but up to now I havenu2019t found it yet.

Maybe I've asked my question too broad. I'll try to narrow it down.
Up to now we always had two clients on our SAP R/3 development system:
- Client 200 - Customizing/development only. No other data in this client
- Client 400 - Local test client with master data and transaction data. New customizing is copied from client 200 to test
The reason for having those two clients are:
- It feels someway good to have a customizing-only client
- We've always done this before
A developer suggested to only have one client in our SAP R/3 development system for the following reason:
- You'll never need to copy the customizing (tr.SCC1) first to be able to test it
- You can work in one client and don't need to login in the other client to test it (for example: ABAP reports)
- For customizing of easy setting (for example producthiërarchie, as we don't test it everytime in client 400) it is possible to forget copying it into client 400 (test client). With one client, you can not forget it
The reasons of this developer seems very valid and up to now we haven't found a convincing/compelling reason to make a good choice for one or two clients.
Please, try to convince us with good reasons to choose for one or two clients.

Experiences on SAP Best Practise packages?

We are considering applying a specific SAP Best Practise package on top of ECC6. It will be a new ECC6 installation.
I have read the BP faq pages http://help.sap.com/bp_bw370/html/faq.htm and read note 1225909 - How to apply SAP Best Practices - and the specific note and the specific installation guide for required Best Practise package.
I understand that applying a BP package is something not that easy but should speed up the implementation process.
If you have been participating in a project that implemented SAP Best Practises on ERP, would you please share your experiences with me.
Here are some topics for discussion:
(BP=SAP Best Practise package)
BP implementation could make constraints to your future EHP or SP upgrades, while BP is tightly linked to certain EHP and SP-level?
SAP support?
Installation process including config steps according BP installation guide is longer than usual, while there can be multiple activation and configuration steps done by others than basis consultants?
BPs are country dependent. What if your application is used multinationally?
What if you later find BP unneccessary?
generate difficulties in the beginning but did considerably speed up reaching the final goal compared to ECC6 without BP.
traps to fall in?
typical issues that basis staff has to notify when preparing/installing a ERP system to be with BP?
positive/negative things
I am not saying above statements are true or false. Just wanted to charge you giving comments.

Hi,
Make sure your web service URL correct in Live Office connection and also in Xcelsius data manager.
Did you check all connection in refresh button proprties? you may try selecting "Refresh after component are Loaded" in Refresh button properties Behavior tab.
I think Xcelsius refresh are serial refresh so it may be possible that first component refresh is still in progress but you are expecting other component to refresh.
Click on "Enable Load Cursor" in data manager's Usage tab, it will give you visibility of refresh. If anything refreshing you will see hour glass.
Cheers

ECC 5.0 and BO without BW/BI Integration Best Practise

Hi,
I know that SAP can connect with BO system using RapidMart (replacing data warehouse BW/BI). Is this best practise?Because when i see the BI Platform RoadMap,I conclude that BI and BO will be integrate into one product, and i'm afraid to invest right now because in the future it seems we need to implement the BW system to make this BI system optimal.
My company want to use BO without implement BW system right now. SAP system that we use right now is ECC 5.0 and my company only upgrade it to next version when version 5.0 not supported again.Thank you.
Cheers,
Satria

Hi Satria,
the answer depends a little bit on what the requirement is.
RapidMarts are an option to implement a data mart solution on top of an ERP solution. On top of the Rapid Marts you can then use the BusinessObjects tools without hitting the OLTP system directly.

BEST PRACTISE on users deletions HR/SU01

Hi
we use CUA/SSO.
The records are fed from HR records and sent to Active Directory (AD)
AD brings backs the records and creates/changes users in SU01
A function module populates the CVR (timesheet) parameter dependent on whether you are an employee or a contractor
Occasionally, our HR department request records to be deleted from the SAP Support team - for example if the employee or contractor hasn't in fact joined the company.
Until some time ago, the deletion was causing problems because:
a) the record does not get deleted in AD and there is no way to send the deletion across after
b) when AD tries to reprocess that specific record, LDAP connector will not find it as HR record so what happens in SU01 for some reasons, the VALID from field gets wiped out and the CVR parameter for Timesheet also...
We have changed the process for the deletion however, I would like to ask if you know what is the best practise for this?? HR want to delete the record so it can be re-utilised
I cannot delete those records from UMR unless I am 100% sure they have never used the system (will have to check that)
I hope I have provided enough info on what the issue is..
Thank you
Nadia

Best practice is not to delete.
> HR want to delete the record so it can be re-utilised
So many people with the same name? Perhaps a suffix of 2 numbers when the ID naming convention produces a clash. Besides, do your AD admins not want unique names in the AD as well?
E.g. (just an imperfect example)
MUSTERMA = Alfred MUSTERMan
MUSTERMM = Manfred MUSTERMan
MUSTER01 = Mechtilde MUSTERMuller
> I cannot delete those records from UMR unless I am 100% sure they have never used the system (will have to check that)
Surest way is to determine that they have never logged on before. But that does not exclude that records might exist for them, which may eventually do a "user existence check" to be read. One such example is the Security Audit Log, e.g. there may have been failed login attempts.
Good luck,
Julius

Transport landscape best practise

I'm wondering if SAP has a best practise document on transport landscape planning.
SAP Help has pretty clear description about a standard 3 system landscape. But not document is found describing complext transport landscape considerations --- multiple ABAP development/test systems, conflict resolution between project landscape and maintenance landscape.
Any feedback is greatly appreciated.

Configure "best practise baseline" manually

Dear experts!
I'm studying SAP ERP as a student. I am interesting in SD. I have read the certification material TSCM and SCM.
Now I am waiting for your advice whether I need to configure "best practise baseline" manually.
We see, it will take a lot of time to configure "best practise baseline" manually.
However, I was thinking that it would be helpfull to my general view on ERP, as well as, I can use it to study "best practise industry" when I complete it.
How do you think?
Waiting for your advice!
Thank you!
Best regard!
Tang Dark

Hi,
Best Practises is a specific SAP solution and to get it you have to specifically buy it - it doesn't come standard with every ERP solution.
What is Best Practises? Best Practises is basically a set of pre configured stuff (BC sets) which you upload into SAP, hence reducing your configuration.
Baseline is basically the general configuration (per module) that a company requires to carry on with config. Things like org structure, etc.
On top of the baseline you can then start loading other more specific BC sets per module.
Best Practises is a methodology to address smaller companies because it reduces the blueprint and configuration phases. Projects can be finalised within 6 months compared to std ERP implementations that may take 1 to 2 years.
If you want to be a proper SD consultant do not study Best Practises only. Do your SAP academy. Best Practises you can learn after you know SAP.
As to Industries specific, these are add-ons to address specific industry requirements. For example, bills of services, is something used in project environments such as engineering & construction. So the funcitonality is not necessary, for example, the retail industry which sells only finished products.
Again, firs learn your SAP and then you can focus on learning others. If you learn SAP you can work on any Best Practices package or any Industry, If you study Best PRactises you can only work with BP, and the same goes for industry solutions.

Best practise for SAP users who leave the company

Hi
Could anyone reccommend a best practise document or give advice on how to deal with SAP user ID's when employee's/contractors/consultants leave? I am the basis admin just starting an SAP implementation and we have no dedicated authorisation team at the moment, so I have been asked to look into this :
Currently we set the validity date in SU01 to the termination date.
We chack there are no background jobs scheduled under that user id, if there are, we change the job owner to a valid user (we try to run all background jobs under an admin account).
We do not delete the user as from an audit point of view I believe it restricts information you can report on and there are implications on change documents etc, so best to lock it with validity dates.
Can anyone advise further?
We are running SAP ECC 5.0 on Windows 2003 64 Bit/MS SQL 2000.
Thanks for any help.

Hi,
Different people will tell you different versions of what they believe is best practice, but in my opinion you are already doing reasonably well.
What I prefer is
1. Lock ID & set validity date.
2. Assign user to user group LEAVER or EXPIRED or something similar (helps with reporting) out of SUIM/S_BCE* reports.
3. Delete role assignment (should you need it, the role assignment will be in the change history docs anyway).
4. Check background jobs & act accordingly.
For ease of getting info I prefer not to delete the ID though plenty of people do.

Business Content Best Practise

Hi Guys
Just a quick request -
I have activated BC a couple of times, but each time it takes longer than it should - missing certain areas, activate far too much etc.
Apart from 'help.sap.com.', does anyone have any Best Practise guides or docs on BC, to allow me to cut down on my activation.
Thanks.

Hi Scott,
I would really commont only to activate with only necassary objects (befor and after is very painfull). Just collect the data structures like DataSource, InfoSource, DataStore Object, InfoCube, ..., Queries (then all Infoobjects gets collected). Then collected the linkages (tranfer rules, transformations, etc.) - these can easily be found in the help menue. after the collection activate it in batch.
best regards clemens

BI 7.0 Best practise

hi all,
I need a the best practise of BI 7.0 ?(latest verison). could anybody help out.
currently i have SAP Best Practices for Business Intelligence V1.30(2009).
Thanks
Ashok

Hi CMS,
Thanks for replying.
Actually, this is the latest version.
http://help.sap.com/bp_biv270/index.htm ( BI 7.0 Best practices version 2)
The link you provided was BW 3.5 version Best Practices version 3.
That's a bit weird naming convention from SAP
There's also a way that you can get this on a DVD or download it rather than access each link on help.sap.com
And i couldn't download it because i don't have download rights for my S-userid.
Thanks

Best practise to feed an infoobject which depend on 0MATERIAL ?

Hi experts,
I'm a newbie on SDN and SAP BW. I have a question that could appear basic for you.
I have to add a new infoobject "Article Typology" in a BW query. I will call it ZTYPOLOGY.
This infoobject will contains 3 values which will depend on the description of 0MATERIAL (field /BI0/TMATERIAL-TXTMD) :
If /BI0/TMATERIAL-TXTMD contains 'MDD', ZTYPOLOGY have to return "MDD"
Elseif /BI0/TMATERIAL-TXTMD contains '#', ZTYPOLOGY have to return "Import"
else ZTYPOLOGY have to return "Other".
I thought to create ZTYPOLOGY as an attribute of the masterdata 0MATERIAL, and feed it by an ABAP routine in the Update Rule which come from 0MATERIAL_ATTR. Is it a good idea ?
If no, could you advise me about the best practise ?
Don't hesitate if you need more information to understand my request.
Thanks a lot.
Tempka

Hi,
First check the source of your query, and see how do you want to see the Typology data in the report, i.e. Always updated data with current master data or the data at the time of transaction.
For e.g. If you add your Infoobject as navigation attribute then you will always see only current master data. And if you add it in your Infocube or DSO etc. then the value will be static and it will show the value which was loaded historically.
Once you finalize your approach you can simply create field routine and load your data.

Durgesh.
