Practical Differences between types of routines....

Hi ,
Which are the practical differences between :
1) a function so as to return a value/data set....
2) a procedure which defines an OUT parameter so as to return a value/data set....Thanks ,
Simon

Performance is another aspect that at times can play a role.
A function passes a value from one stack to another stack - reference by value. This means the result of the function is copied from the function's stack to the caller's stack when the function terminates and its stack is popped.
A procedure can use reference by name (pointers). In this case the output of the procedure's parameter is written directly into the variable of the caller. No copying.
When the parameter is large (think CLOBs for example), a function returning a CLOB can be significantly slower that a procedure with a IN OUT NOCOPY CLOB parameter.

Practical differences between static IP and loopback installation

Hi,
I'm planning the installation of 10gR2 on my windows laptop at home. I can set my laptop up to use either a static or dynamic IP address before installing the db. I'm not sure which way would be best though. I'm aware that, if I use a dynamic IP/DHCP setup, then I will need to install the loopback adapter for Oracle to work properly.
Are there any practical differences between a static IP db installation versus a dynamic one? I.e. if I choose the dynamic IP/loopback adapter approach, will I still be able to connect to my laptop's database via other pc's on my home network?
My home setup looks like this.
ISP -> DSL Modem -> Router -> various PC's
I'd also like the flexibility to connect my laptop to my work's WAN and access my laptop db from my work PC. I suspect this will harder to do if I use the static IP approach.
My laptop runs Windows XP and I'm planning to install either the Enterprise Edition or Personal Edition of 10gr2. I suspect that the Personal Edition, being restircted to a single user, may refuse connections from machines other than the one it is installed on, but I'm not sure about this. Can anyone confirm?
Thanks in advance for your help.

I personally prefer static IP too, what I can do with static and not dynamic is:
use the IP address in various codes and scripts specially host and batch.
you can reach the same result by using the hostname too BUT in case of windows that might be let's say not quite accurate all the time ;) specially when nslookup and DNS/WINS are drunk :))

Difference between type lvc_t_fcat and slis_t_fieldcat_alv

Can you tell me the difference between type lvc_t_fcat and slis_t_fieldcat_alv?
Both are used for field catalogue so which one is better to use?

Hi,
the field catalog using lvc_t_fcat has some better and enhanced features over the old slis_t_fieldcat_alv.
Ideally when displayed a normal ALV using these fieldcatalogs does not have any difference...
You can more enhanced features of ALV using lvc_t_fcat but these cannot be done using slis_t_fieldcat_alv
For using lvc_t_fcat, you require a screen and a container area...
Based on the requirement, use the fieldcatalogs.
Also slis_t_fieldcat_alv does not have any classes or methods but the other has so..(objecct oriented)

Difference between types of plan data

Hi Friends,
BPS
1. Cost Center Planning: Costs and Allocations
2. Cost Center Planning: Activity Type Prices
3. Cost Center Planning: Cost Center/Activity Type Prices
4. Cost Center Planning: Cost Driver
For the above types of data, I like to understand what is the difference them.
For type 1, I understand it is for primary costs.
For type 2 and 3 they are related / same type of data. So what is the difference between them?
For type 3, seems like combo of types 1 and 2.
For type 4, I am not sure what it is about.
Questions I have:
1. Why is it only primary costs. Where is secondary costs?
2. Type 1 costs is identified by cost elements of costs centers. But type 2 is by activity, quantity and rates ( i think). And costs calculated. So, is this type of cost outside the cost calculation of type 1 such that to get wholistic cost picture, need to add types 1 and 2 at least? Thus, are they mutually exclusive.
3. Now, how does the same apply to type 4?
4. What is the purpose of type 3?
Hope you could advise me friends
Regards
Michael

Hello Michael,
Different types of CO planning relate to how an organization is using SAP Controlling functionalities. Activity represent typically internal labor/machine provided by one department (cost center) to a production order, project network etc. depending on the type of organization (production activities or project-driven operation etc.). Activity price would set per cost center for time of periods (months), representing standard price for valuation of actitivities.
More CO documentation attached:

Hi
Standard analyse
You can analyse various customer related information in this
Flexible reporting
Assume you want to analyse sales flow of the customer in all the years and compare it with the current year. Some complex scenario...
Early warning report
Assume that you want a report which indicates the list of customer whose sales transactions has been reduced by 10% in the current year compared to the last year
This kind of reports gives you early indication of possible future trends which could be traced to a reason and possible action could be followed up on the customers

Difference between type of IViews

Hello All,
    Could anyone please tell me what are the major differences between ITS Iviews and Transaction Iviews?
    I am working on ESS using ITS 6.2What is the advantage of using ITS Iviews when the transaction Iviews are also available?
Thanks,
Deepti.

Hi Deepthi,
   Transaction iviews are Master iviews. These are not displayed in a page of MySAP.com Enterprise Portal. These are Java coded elements that enable the following applications and objects to run in the MySAP.com Enterprise Portal as Java iViews or External Services.
R/3 transactions
R/3 reports
   ITS iviews are External Services iviews. These are pieces of content that are displayed in a page of the
MySAP.com Enterprise Portal.
External Services are similar to Java iViews. They also inherit properties from the Master iView upon which they are based. External Services are normally displayed in the Portal as full-page iViews, unlike most Java iViews.
Unlike .NET iViews and Java iViews, External Services cannot be assigned or directly linked to a Portal page. They are assigned to Portal users through role,
directory, or workset assignments. In addition, External Services do not run on the iViewServer or Java iView Runtime servlet engine.
   Java iViews are pieces of content that are displayed in a page of the MySAP.com Enterprise Portal.
Java iViews are typically written in JSP or Java and run on the Java iView Runtime servlet engine. A Java iView inherits its properties from the Master iView upon which it is based.

Pooja.

Difference between "type"'s of laptop model's - X201

I've got two X201 laptops, that seem identical, except for the processor (one is an i5 2.4. and the other is an i5 2.53). Also, the computer "type" is different on them. One is a 3249 and the other is a 3680. The only reason I care is that I was moving a hard drive from one of the laptops to the other laptop and figured the hardware is identical (besides the processor type) and that it wouldn't have any issues. When Windows tries to boot with the first hard drive in the second system, I constantly get the blue screen. Windows can't seem to repair the windows install, and if I put the hard drive back in the original system, it boots just fine. I can't believe that just a higher speed processor would cause this to blue screen. I've swapped hard drives between "like" dell systems in the past with no problems (even when there were different processors, but the same model laptop). Why do they have so many "type's" of this system and does anyone know where I can find the differences. You would think the types and differences would be posted somewhere but I can't find it.

Difference between type of Secondary Cost Element Category?

Hi,
I checked the system, and during the secondary cost element (CE) creation, I can select some of the CE category as follows:
21 Internal settlement
31 Order/project results analysis
41 Overheads
42 Assessment
43 Internal activity allocation
50 Project-related incoming orders: Sales
51 Project-related incoming orders: Other
52 Project-related incoming orders: Costs
61 Earned value
My question, what kind of report that I can read entries with these kind of CE?
Reason: I want to check what has been posted to these secondary CE.
Or
Could anyone explain the use of above-mentioned CE category in brief?
Thanks.

Cost element that is used to allocate costs for internal activities.
Most often used categories are
21 Internal settlement
(When ever an order is settled e.g internal order settling to cost center through this type of cost elements)
31 Order/project results analysis
(WIP in production orders are calculated and posted using this category)
41 Overheads
(Used in costing sheet to do an overhead allocation)
42 Assessment
(whenever cost is allocated between cost centers through allocation method - Assessment)
43 Internal activity allocation
(found in production orders when a routing activity is confimed the charge goes to the production order through this cost element)

What is the difference between TYPE and LIKE exaclty.

Hi,
Type refers to data type like C or I or N etc...
example :
matnr type mara-matnr.
Like refers to data object.
can also use in programs like:
matnr like mara-matnr.
I am not getting the exact difference in both.

Difference between TYPE and LIKE?

data: a type "a data element",
b like a.
I know the basic difference of these two statement. But what is the insight?

Have a look at below links:
http://help.sap.com/saphelp_nw2004s/helpdata/en/fc/eb367a358411d1829f0000e829fbfe/content.htm
http://help.sap.com/saphelp_nw2004s/helpdata/en/fc/eb2ff3358411d1829f0000e829fbfe/frameset.htm
If you use the addition TYPE, you can either reference to an inbuilt ABAP type, a predefined elementary type in the local program, or to a data element defined in the ABAP Dictionary. If you use a LIKE reference, dobj can be an existing data object with an elementary data type. If you do not use the TYPE or LIKE addition, the system uses the default predefined type c.
In other words, LIKE means the datatype of the variable is similar to the referenced variable.
TYPE means it is a predefined data type.
Eg:
DATA int TYPE i.
Here int is of integer data type.
DATA var LIKE int.
var IS a variable having same data type of int. which in turn is integer.
You can find these helpful when you reference database table variables... You need not know what is the datatype defined.
Also it adds to FLEXIBILITY.
Whenever you make changes to your database tables and fields, that change is REFLECTED back to your program that is, You need not change all your program code when you change your table fields...
I hope it helps.

Vibha

RV042 - What's a practical difference between gateway and router mode

That´s my scenario, I have a RV042 as gateway on subnet 192.168.254.0,subnet 192.168.0.0 on the same LAN and 3 vpn tunnels connected GATEWAY TO GATEWAY on subnet 192.168.1.0,192.168.2.0 and 192.168.4.0. I setup 192.168.0.0 as Multiple Subnet on RV042 so now i can ping 192.168.0.0 from RV042 but i can´t do this from clients. What i want to know is What will happen if i change RV042 mode from gateway to router and What do i do to make clients (workstations) on subnet 192.168.254.0 reach clients in subnet 192.168.0.0 .
Thx
Everyone

Gateway mode = RV042 does NAPT (network address & port translation);
Router mode = RV042 does not do NAPT
