Documentation for SAP MILL

Dear Seniors,
I am a SAP Consultant with experience in PP. I have now a request for a customer that uses SAP MILL.
I was trying to find on the internet some resources about SAP MILL and I did not find much.
Do you know where I can find documentation about SAP MILL or some SAP standard courses about this ?
Many thanks in advance for your great support,

Dear Alex,
can yuo help me and explain briefly what you mean with "SAP Mill"?
Has the customer activated the DIMP (Discrete Industries Mill Products)-Industry Externsion in ECC - and you would thus like to learn more about IS-MP-PP?
Are you interested only in PP functionality, or also functionality related to SAP APO?
As a starting point you always use help.sap.com and follow the path:
SAP Business Suite - SAP ERP - you release - and application help.
Further on to "Industries in SAP ERP" - SAP Discrete Industries and Mill Products" - SAP Mill Products.
Or you can directly click here: SAP Mil Products and select the application area you are interested in.
Are you looking for a solution to a specific problem?
Regards,
Stefan

Official documentation from SAP about field exits as obsolete

Hi all,
I want to know if there is any official SAP documentation about the support of field exits. Because, I herad some time ago that they are obsolete and its use is not recomended from 4.6C onwards.

Check OSS note 29377.

Beware UNC path syntax for shared dirs used in a windows cluster!

This seems to be an undocumented but vital piece of information:
If you are setting up a Windows based cluster and you are using UNC paths
to identify the shared file locations for IntradocDir (Instance Dir), Vault dir
and Weblayout dir, please start your paths with 4 backslashes!
For instance, if you are putting your share on \\MYNAS\share\cs
The paths as configured in the intradoc.cfg should follow this pattern:
IntradocDir=\\\\MYNAS/share/cs
VaultDir=\\\\MYNAS/share/cs/vault
WeblayoutDir=\\\\MYNAS/share/cs/weblayout
Now, the documentation, if read carefully, will lead you to believe starting
with two forward slashes will work.
In other words, like this:
IntradocDir=//MYNAS/share/cs
And on an initial system start, it may even seem good to go, BUT BEWARE!
When using only the forward slashes, at least two problems may arise:
1. Any custom component which use java and therefore require a classpath may
fail to load their classes. This will result in ClassNotFound exceptions
when class loading is attempted.
2. OracleTextSearch may not be able to index files and you will see "oit" errors
in the log.
This may be jvm and windows version specific but I noticed this on Windows server 2008 R2
using the JRockit 64 bit jvm.

As mentioned above I spotted Shadow Copy configuration problems in clustered environment on Windows 2012 R2 with latest updates.
Enabling Shadow Copy via Cluster Manager on disk will enable schedule and snapshots but schedule is not-cluster aware (is created locally on node) and "Previous Versions" are visible only locally but not via shared folders (UNC path accesible by
clients)
When I spotted this behavior I tried different way going via Computer Management and cluster resource name but console always hangs for me when using "Configure Shadow Copies". After many minutes configuration window is opened (Hurray!) but any
action there will hang whole console again. Enabling Shadow Copies will fail with "0x80004005: Unspecified
error" for creating scheduled task but "Next Run Time" column still shows "Disabled". Checking disk resource via Cluster Manager shows it is enabled and ?local? scheduled task is created.
Computer management console still shows DISABLED and any action freezes whole console (only when cluster resource name is used).
This fix I found, unfortunately, is not applicable to 2012 R2 OS: https://support.microsoft.com/en-us/kb/2894464
To sum up there is a major bug in MS implementation in Shadow Copies for Shared Folders when clustering is used or it is still not supported in 2012 R2? Doing it outside cluster works as it should (without freezes and Previous Versions are available via
UNC)
There is no documentation about FileServer Clustering on 2012(R2) unfortunately.
Could someone from MS clarify it?
Many thanks
Filip
EDIT:
Ok, one correction:
Scheduled task is not created in "Failover Clustering" hive of Scheduled tasks as user may expect but failover of fileshare to other node will unregister/reregister it on active node only.

Can we install a new mssql cluster on the same windows cluster which already containes a mssql cluster with named instance

We have a MSSQL 2008R2 Enterprise edition with a two node active passive fail-over cluster running on 2008R2 windows cluster with out any issues,
Now my question is can we add one more MSSSQL cluster instance for the same setup with out disturbing the existing one ?
Also give thoughts on load sharing as the second node is mostly ideal now except fail-over scenarios,
Why we go for this situation is because of the collation setting which can be set only one per instance(Database collation setting change not working), we need a different default collation for the new setup

hi,
>>Now my question is can we add one more MSSSQL cluster instance for the same setup with out disturbing the existing one ?
Yes it is possible .You need to add new drives as cluster aware and install SQL server and put data and log files on thse drives.YOu would need to create named instance of SQL server and need to create different resource group.Both old installation and new
onw would work separately.
>>Also give thoughts on load sharing as the second node is mostly ideal now except fail-over scenarios,
Good point indeed.You are about to create Multi instance cluster and should plan for scenario where one node is down and other node is handling load for both instances.Memory and CPU should be enough to handle the load.
>>Why we go for this situation is because of the collation setting which can be set only one per instance(Database collation setting change not working), we need a different default collation for the new setup .
Just for collation if you are installing new instance seems little wierd to me.You can manage collation at column ,database and at server level.

Where can I find a documentation about RRX_GRID_CMD_PROCESS and RRX1 fm?

In fm RRX_GRID_CMD_PROCESS there several parameters: where can I find a documentation (tutorial, examples, references, manuals, books or others) about it?
And, in general, about the RRX1 funtion modules?

Hello. Not sure this will help you much, but figured I would give you my thoughts. I have never seen official documentation on SAP FMs. For me, it's been a matter of figuring what is there and how they work, as needed.
Mainly, I would just look at the source code to get an idea of what the FM is doing. Then also find where the FM is being called from other programs/FMs. That would give you an idea of how other processes are utilizing the FM as well as what they are passing and how they are handling the returned data.
Maybe others know if actual documentation, but I have never seen it and usually just figure them out as mentioned above.
Thanks

Installation of SAPCCM4X-Agent on Windows Cluster

Hi!
I woulld like to install SAPCCM4X-Agent on Windows Cluster.
Does anyone know the procedure here (e.g. install the agent twice on both nodes, etc.)...
Thank you very much!
regards
Thom

Hello Thom,
Here is a note that will help you out.
SAP Note 536954 - OS data in a cluster environment for OS07
As per the note
The CCMS agent must be located on a shared disk, so that the cluster administrator software can start the service later.

Is there any Documentation about MDM4J (Java API) ?

Hello to all,
I was wondering... Is there any possibility to get documentation about the classes in the MDM4J.jar ?
We can not use the other Java Api, and we need to understand this one.
Thanks in advance,

Exactly, but, I don't have the javadoc that are included with MDM4J. Are the javadocs always shipped with the MDM4J.jar?

Documentation about flashinstall.log

Hello,
does exist a documentation about the contents of the FlashPlayer installation log file "flashinstall.log"?
It could be interesting to understand the entries. Additionally the documentation of the error codes could help to find and fix installation/update problems...
'til now, I haven't found any documentation about on Adobe pages. I found, how I can activate/deactivate logging, but nothing about the structure, the meanings, error codes, etc....
Best Regards
Axel

Thank you Pat for the hints...
It's interesting, if you receive a warning in the log without a hint about the problem... :-)
I found this in a log, without any information behind the numbers or is it caused by the last entry?

Types of Exits 
There are several different types of user exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.
Menu Exits
Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Screen Exits
Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screens flow logic.
Function Module Exits 
Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits.
When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated.
Function module exits also control the data flow between standard programs and screen exit fields. SAP application developers create function module exits by writing calls to customer functions into the source code of standard R/3 programs.
These calls have the following syntax:
CALL CUSTOMER-FUNCTION 001.
Field Exits
Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field. Example: The data element BBBNR identifies a companys international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100.
The field exit concept lets you create a special function module that contains this logic.
You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.
In 4.6c, you can use "RSMODPRF" program to create field exits.
An example of a user exits :-
MODULE user_exit_0001 INPUT
 CASE okcode.
 WHEN 'BACK OR EXIT'.
 CASE sy-dynnr.
 WHEN '100'.
 SET SCREEN 0.
 LEAVE SCREEN.
 WHEN '200'.
**** Note that you can write any code that satisfy your needs. ****
**** But in this case, this was wrote as a sample code for reference sake. ****
**** And you can test it. ****
 SET SCREEN 100.
 LEAVE SCREEN.
 ENDCASE.
 ENDCASE.

Documentation about variable types & their processing in i_step = 1, 2 etc.

Hello experts,
is there any documentation about variable types and their processing in i_step = 1, 2 etc.? I know there is note 492504 "Dependent customer exit-type variables", but I don't understand, whether a variable which is NOT "Ready for input" will be processed in i_step = 1 or not (quote of SAP library: "i_step = 1: Call takes place directly before variable entry."). I experienced coincidentally, that some variables not "Ready for input" will be processed there and some not.
Furthermore it is an error, isn't it? Why has a variable without input possibility to be processed before input? Is this really the case?
Confused, any hints are welcomed!
Regards M.L.

for I_STEP = 1
Call before the variable screen .
for I_STEP = 2
Call after variable entry. This step is only started up when the same variable is not input ready and could not be filled at I_STEP=1.
for I_STEP = 3
In this call, you can check the values of the variables. Triggering an exception (RAISE) causes the variable screen to appear once more. Afterwards, I_STEP=2 is also called again.
for I_STEP = 0
The enhancement is not called from the variable screen. The call can come from the authorization check or from the Monitor.
There is a good HOW to Guide which explains the importance of I_STEP :
