Difference/Dependency of RZ21 and DSWP

Please let me know whats the diffrence in configuring CCMS alerts in RZ21 (CEN- SOL) and configuring CCMS in(CEN- SOL) Solution Manager -> DSWP -> Solution Monitoring ?? is Solman-> Solution Monitoring a shortcu way or a WIZARD way to RZ21 (creating CCMSUSR, CCMSREG .. etc what ever we do in RZ21) or we need to configure RZ21 as prerequisite to configure solution monitorind in DSWP

Hi Paul,
Thanks for your reply, i am bit confused or making you people confused by posing an unclear question..
I Belive there are two ways to configure CCMS on (CEN-SOL)
1. Configure RZ21 on (CEN - SOLMAN), ie Add satillite systems by creating RFC Connections and adding them viwed in Agents for Remote systems (Satillite systems) by creating CCMSREG and CCMSUSR and registring them in on Sat systems etc.. and here in this scenario i think we dont configure any CCMS alerts on (Local)satillite systems insted we configure CCMS alerts in RZ20 on (CEN) to each Sat system centrally, and then we can also collectivly send a mail to recivers.
summary is that everything is done on CEN, except Registering the satillite systems which is done on Sat systems
no conf is done in RZ20 on Sat systems.. No Local Config
2.By Using Solution Manager, DSWP which relies on CCMS Architecture of Tech Alerts and additionally also provides Buss Funct Alerts .
Here it also checks for RFC Connections to resp sat systems, and here even in this scenario also we configure all req alerts for sat systems in Solman and even define methods for how to react to the alerts but not in Sat systems
Even here we dont do any thing on sat systems, No local config on sat systems, except creating RFC connections to them, we do all alert conf in CEN DSWP-> Solution Monitoring, for all sat systems
The advantage here is we can view alerts in Graphical/session view compared to RZ20 which just diplays alert status and secondly i belive we cant log on to the satt sys from RZ20
My doubts for confg CCMS are
a.i need to configure RZ21 and DSWP both like
Do i need to create CCMSREG and CCMSUSR in RZ21 on SOL and register them in Sat systems prior to conf in DSWP
or
b.i can configure DSWP without RZ21 except RFC Connections for Sat systems
ie will Solution monitoring conf in DSWP will do it by itself reg sat systems automatically
and lastly
the link i posed speaks about configuring Auto reaction method for sending emails, in both the cases that should not be the issue unless if i cant specify an Auto reaction method to an alert of sat sytem
from central Sys (CEN)
Please correct me if i am wrong
Thanks
Karthik

Hello,
system monitoring in Solution Manager could be described as a layer on top of RZ21, which provides some advantages as centralization, possibilities of reporting and better overview, etc.
Technically you have to configure RZ21 before you can connect the Solution Manager system monitoring to it. In SPRO you can refer to:
SAP Solution Manager
Basic Settings
Cross-Scenario Settings
Central CCMS Setup
I think this is the closest to a 'Wizard' for CEN configuration in the Solution Manager IMG that there is.
I hope this information helps.

When I import videos taken with my iPhone 4S to my Windows PC some of the landscape videos are upside down and all of the portrait videos are rotated 90 degrees. It makes a difference depending how I hold the iPhone when taking videos. Help!!!

When I import videos taken with my iPhone 4S to my Windows PC, some of the landscape videos are upside down and all of the portrait videos are rotated 90 degrees. It makes a difference depending on what position I hold the Iphone when taking videos. Help!!!!

Sometimes syncing will have problems with very large video files like this. I'm not sure you will be able to overcome this, but if the videos are important enough you may consider purchasing 3rd party software such as Touch Copy to transfer them.

What is difference between report programming and dialog programming?

hi,
what is difference between report programming and dialog programming? plz provide some example code
bye

ABAP programming
Basically reports are used to read database and represent the results in lists.
Reports are collections of processing blocks that the system calls depending on events.
We can use reports to evaluate data from database tables.
Reports are stand alone programs and controlled by events.
A report itself never creates events
steps in report:
Processing the selection screen
Reading the database
Evaluating the data and creating lists
Outputting a list.
1st u write simple logics, after that u can enhance the code as step by step.

Dialog Programming
Structure of a Dialog Program
A dialog program consists of the following basic components:
Screens (dynpros)
Each dialog in an SAP system is controlled by dynpros. A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).
The screen layout fixed in the Screen Painter determines the positions of input/output fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.
ABAP/4 module pool
Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.
All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.

What is difference between Shared ,Exclusive and Exclusive but not commulat

what is difference between Shared ,Exclusive and Exclusive but not commulative lock modes plese tell me

Lock objects are used to synchronize access to the same data by more than one program.
The lock mode controls whether several users can access data records at the same time. The lock mode can be assigned separately for each table in the lock object. When the lock is set, the corresponding lock entry is stored in the lock table of the system for each table.
There are three types of lock modes
1.Exclusive
2.Shared
3.Exclusive not cummulative
Exclusive lock: The locked data can only be displayed or edited by a single user. A request for another exclusive lock or for a shared lock is rejected.
Shared lock: More than one user can access the locked data at the same time in display mode. A request for another shared lock is accepted, even if it comes from another user. An exclusive lock is rejected.
Exclusive but not cumulative: Exclusive locks can be requested several times from the same transaction and are processed successively. In contrast, exclusive but not cumulative locks can be called only once from the same transaction. All other lock requests are rejected.
please go through these links:

http://help.sap.com/saphelp_nw04/helpdata/en/cf/21eed9446011d189700000e8322d00/frameset.htm
briefly :
You can lock the table or record by using following types of locking:
1) Exclusive (E) the locked data can only be displayed or modified by single user i.e the owner of the object. Access to other users is denied.
2) Shared (S) several users can access the same record simultaneously, but only in display mode and except the first one, who has asked for the data in update mode.
3) Exclusive not cumulating (X) it is similar to exclusive lock. It allows only a single user access. E can be called several times from the same transaction. In contrast, a lock type X can be called only once during the transaction. Any other call for this lock is rejected.
Activation of Lock Object
1) When you activate the lock object, the functions are automatically generated. And these are ENQUEUE-EZN and DEQUEUE-EZN. EZN is name of the lock object.
2) While ENQUEUE is used in program to set the code over the selected data depending upon the lock object arguments. DEQUEUE is used to release the lock.

Difference between Temp table and Variable table and which one is better performance wise?

Hello,
Anyone could you explain What is difference between Temp Table (#, ##) and Variable table (DECLARE @V TABLE (EMP_ID INT)) ?
Which one is recommended to use for better performance?
also Is it possible to create CLUSTER and NONCLUSTER Index on Variable table?
In my case: 1-2 days transactional data are more than 3-4 Millions. I tried using both # and table variable and found table variable is faster.
Is that Table variable using Memory or Disk space?
Thanks Shiven:) If Answer is Helpful, Please Vote

Check following link to see differences b/w TempTable & TableVariable: http://sqlwithmanoj.com/2010/05/15/temporary-tables-vs-table-variables/
TempTables & TableVariables both use memory & tempDB in similar manner, check this blog post: http://sqlwithmanoj.com/2010/07/20/table-variables-are-not-stored-in-memory-but-in-tempdb/
Performance wise if you are dealing with millions of records then TempTable is ideal, as you can create explicit indexes on top of them. But if there are less records then TableVariables are good suited.
On Tables Variable explicit index are not allowed, if you define a PK column, then a Clustered Index will be created automatically.
But it also depends upon specific scenarios you are dealing with , can you share it?

Difference between unique constraint and unique index

1. What is the difference between unique constraint and unique index when unique constraint is always indexed ? Which one is better in this case for better performance ?
2. Is Composite index of 3 columns x,y,z better
or having independent/ seperate indexes on 3 columns x,y,z is better for better performance ?
3. It has been very confusing for me to decide which columns to index, I have indexed most foreignkey columns, is it a good idea ? We do lot of selects and DMLS on most of our tables. Is there any query that I can run and find out if indexes are really being used and if they are improving any performance. I have analyzed and computed my indexes using ANALYZE index index_name validate structure and COMPUTE STATISTICS;
null

1. Unique index is part of unique constraint. Of course you can create standalone unique index. But is is no point to skip the logical view of business if you spend same effort to achive.
You create unique const. Oracle create the unique index for you. You may specify index characteristic in unique constraint.
2. Depends. You can't utilize the composite index if the searching condition is not whole or front part of the indexing key. You can't utilize your index if you query the table for y=2. That is.
3. As old words in database arena, Index may be good or bad for a table depending on the size of table, number of columns in the table... etc. It is very environmental dependent. In fact, It is part of database nomalization. Statistic is a way oracle use to determine the execution plan.

What is the difference between scheduling agreement and delivery schedule

Hi
1. Can anyone explain me the difference between scheduling agreement output
    and scheduling agreement delivey schedule
    Will the both look same in T.code SP02 when seeing the output for a document.
    Can anyone send me T.codes for above ones in purchasing.
2. when seeing the Detailed statement for rebate agreement,there is item number.
    In which table can we see the item number for rebate agreement

Hi,
If you have to deal with more complex situations, you can define a delivery cycle in the material master record in addition to the planning cycle. In so doing, you determine the days on whichthe vendor delivers his goods. The delivery cycle is entered in the material master record as a planning calendar in the Planning calendar field.
You enter a delivery cycle if the delivery date (or the goods receipt date) depends on the day on which you order the goods. For example, you carry out the planning run and place your orders on Mondays and Tuesdays. If you place the order on Monday, the delivery is made on Wednesday, if you wait until Tuesday to place the order, the delivery is not made until Friday
Where as Planning calander is Three character number (numeric or using letters) that specifically identifies a PPS-planning calendar. The difference between Planning calender and delivery cycle is If you have selected the MRP type "MRP" and have set a period lot-sizing procedure according to planning calendar, you enter here which planning calendar is to be used.
If you selected the "time-phased planning" MRP type, the planning calendar that you specify here defines the delivery cycle. This specifies the days on which the vendor delivers the material. You can enter the planning cycle in addition to the delivery cycle

Difference between customizing request and workbench request?

Hi ,
What is the difference between customizing request and workbench request?
please reply.........

HI,
<b>Workbench Requests</b>
When you change a Repository object of the ABAP Workbench, a query window appears in which you need to specify a Workbench request. You can only save the changes if you have assigned the object to a change request.
Workbench requests and the tasks assigned to them are normally used to record changes to Repository objects and Customizing for all clients. However, you can also include client-specific Customizing.
Whether the changes to Repository objects are transported depends on whether a transport route is defined from the current SAP System for the package of these objects. From the system settings, the system automatically determines whether the change requests are transportable and to which target system they should be transported.
<b>Customizing requests</b>
Customizing requests record client-specific Customizing settings made in a single client (the source client of the request).
Automatic recording of configuration activities in the Customizing work for a client can be activated or deactivated for each client with Client Control. If automatic recording is active, a query window appears when you change Customizing settings, asking you to specify a Customizing request.
Whether Customizing requests are transported or not, does not depend on the objects entered, as is the case with Workbench change requests. The Customizing requests in an SAP System (or in a client if you use Extended Transport Control) are either all transportable or all local, depending on the system setting. The system uses the standard transport layer to determine automatically whether the change requests are transportable and to which target system they should be transported. However, you can change this manually.

Quantity & price difference between purchase order and goods receipt

goods receipt against purchase order
inventory a/c    dr
   gr/ir clearing a/c    cr
if there is any quantity & price difference in between PO and GR ex- PO order -1000 bags @ rs 10 but good receipt 900 @ Rs 10
then how the price difference and quantity diference treated in sap
what will be the entries, how we adjust it.
regards
siba

kindly note that depending on the Moving average or standard price (price control flag in mm01) the difference will either get adjusted with the material or to the price difference account accordingly.
in the example for standard price
         gr for po :10 bags @ 11
dr stock 100
cr gr/ir 110
dr price diff 10
the above is in case of material maitained at 'Standard price' in the mm03.

Difference between task request and change request

What is the difference between task request and change request during sap implementation. In general how many tasks will generate during a normal company inmplementation by any functional consultant?

Hi,
Change request and task request are same.But generally change request is generated during newly created objects or reports that are transported and task request is used when u regenerate the change request by modifying that object again and transporting it in new change request.
A particular change request may contain multiple number of task request but that number depends upon number of objects u transfer during generation and transportation.
Pls do reward points if ans is useful.

Difference between Drilldown report and Interactive report

There is no difference between drill down and interactive report, they are the same.
With drilldown reporting, SAP provides you with an interactive information system to let you evaluate the data collected in your application. This information system is capable of analyzing all the data according to any of the characteristics that describe the data. You can also use any key figures you wish to categorize your data. You can display a number of objects for a given key figure, or a number of key figures for a given object. In addition, the system lets you carry out any number of variance analyses (such as plan/actual comparisons, fiscal year comparisons, comparisons of different objects, and so on).
You can produce both simple, data-directed lists (basic reports) and complex, formatted lists in drilldown reporting (form reports).
Drilldown report provides you with comfortable functions for navigating through your data. For example, you can jump to the next level of detail or the next report object on the same level, hide individual levels and switch between the detail and drilldown lists. It also provides a number of additional functions which let you process lists interactively (sorting, conditions, ranking lists, and so on). SAP Graphics, SAPmail and the Excel List Viewer are also integrated into drilldown reporting.
The drilldown functions are divided into three groups which differ in the number of functions available. That way each user can choose the functional level most suited for his requirements.
In addition to the online functions for displaying reports, drilldown reporting also provides functions which let you print reports. A number of formatting functions are available to let you determine the look of your printed reports (page breaks, headers and footers, underscores, and so on).
The menus and the functions available directly on the drilldown report make it easy to use the information system.
What is an Interactive Report?
An interactive report generally works in the following fashion:
1. Basic list is displayed.
2. User double clicks on any valid line
    or
    User selects a line and presses as button on the tool bar.
3. The corresponding event is triggered
4. Then in the code, the line on which action was done, is read.
5. Depending on the values in that selected line, a secondary list is displayed.
6. Steps from 2-5 are repeated till the end.
From the above explanation, I believe, its clear that, the 20th list, will essentially depend on the "selected line" of 19th list. According to your question, you want to move to 20th list directly, without "a prior list". May I know the exact requirement so that, an appropriate solution can be suggested?
Again, your question was, how to move to 20th list directly on pressing of execute button. Its not possible to move to 20th list. You must cross over a basic list, before you can go to a different list level, using the code given by Pavan.
What are Drilldown reports?
The lines of basic list of a drilldown report when clicked, will take the user to the corresponding (standard) object's display.
For eg: Suppose your report's primary component is purchase requisition, (assume you are printing PR details), and the basic list displays details of many PRs.
Eg: when clicked on a particular line of the PR basic list, it takes you to std t-code me53 (display of purchase requisition). This is the 'Drill-down' functionality.
For this, in the at-line selection of your program, as per the above ex: you'll set the parameter ID of PR number BAN (that you can get from Data element) in memory (using set parameter id) and then calling the corresponding transaction (usually skipping initial screen of the std t-code).
Likewise, if it's Material Number (Matnr), you'll be displaying MM03 transaction w.r.t. the line's matnr.

Difference between Business Partner and Customer in ISU?

Is there any difference between business partner and customer in ISU?
if yes then wht?

Hi,
Yes Business Partner is a broad term used in ISU for various roles. A business Partner can be a Customer for company, an employee or even a vendor.
It depends on what role business partner has been given. Initially by default all Business Partners are assigned a default role "Business Partner (Gen.)". Later it can be changed to any role like Employee, Vendor, etc.
Business Partner with role "Contract Partner" is normally the end Customer which I believe you are referring to.

Question about main difference between Java bean and Java class in JSP

Hi All,
I am new to Java Bean and wonder what is the main difference to use a Bean or an Object in the jsp. I have search on the forum and find some post also asking the question but still answer my doubt. Indeed, what is the real advantage of using bean in jsp.
Let me give an example to illustrate my question:
<code>
<%@ page errorPage="errorpage.jsp" %>
<%@ page import="ShoppingCart" %>

<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
<html>
<head><title>Shopping Cart</title></head>
<body bgcolor="#FFFFFF">
Your cart's ID is: <%=cart.getId()%>.
</body>
<html>
</code>
In the above code, I can also create a object of ShoppingCart by new operator then get the id at the following way.
<code>
<%
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
%>
</code>
Now my question is what is the difference between the two method? As in my mind, a normal class can also have it setter and getter methods for its properties. But someone may say that, there is a scope="session", which can be declared in an normal object. It may be a point but it can be easily solved but putting the object in session by "session.setAttribute("cart", cart)".
I have been searching on this issue on the internet for a long time and most of them just say someting like "persistance of state", "bean follow some conventions of naming", "bean must implement ser" and so on. All of above can be solved by other means, for example, a normal class can also follow the convention. I am really get confused with it, and really want to know what is the main point(s) of using the java bean.
Any help will be highly apprecaited. Thanks!!!
Best Regards,
Alex

Hi All,
I am new to Java Bean and wonder what is the main
difference to use a Bean or an Object in the jsp. The first thing to realize is that JavaBeans are just Plain Old Java Objects (POJOs) that follow a specific set of semantics (get/set methods, etc...). So what is the difference between a Bean and an Object? Nothing.
<jsp:useBean id="cart" scope="session" class="ShoppingCart" />
In the above code, I can also create a object of
ShoppingCart by new operator then get the id at the
following way.
ShoppingCart cart = new ShoppingCart();
out.println(cart.getId());
...Sure you could. And if the Cart was in a package (it has to be) you also need to put an import statement in. Oh, and to make sure the object is accessable in the same scope, you have to put it into the PageContext scope. And to totally equal, you first check to see if that object already exists in scope. So to get the equivalant of this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart"/>Then your scriptlet looks like this:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = pageContext.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    pageContext.setAttribute("cart", cart);
%>So it is a lot more work.
As in my mind, a normal class can also
have it setter and getter methods for its properties.True ... See below.
But someone may say that, there is a scope="session",
which can be declared in an normal object.As long as the object is serializeable, yes.
It may be
a point but it can be easily solved but putting the
object in session by "session.setAttribute("cart",
cart)".Possible, but if the object isn't serializable it can be unsafe. As the point I mentioned above, the useBean tag allows you to check if the bean exists already, and use that, or make a new one if it does not yet exist in one line. A lot easier than the code you need to use otherwise.
I have been searching on this issue on the internet
for a long time and most of them just say someting
like "persistance of state", "bean follow some
conventions of naming", "bean must implement ser" and
so on. Right, that would go along the lines of the definition of what a JavaBean is.
All of above can be solved by other means, for
example, a normal class can also follow the
convention. And if it does - then it is a JavaBean! A JavaBean is any Object whose class definition would include all of the following:
1) A public, no-argument constructor
2) Implements Serializeable
3) Properties are revealed through public mutator methods (void return type, start with 'set' have a single Object parameter list) and public accessor methods (Object return type, void parameter list, begin with 'get').
4) Contain any necessary event handling methods. Depending on the purpose of the bean, you may include event handlers for when the properties change.
I am really get confused with it, and
really want to know what is the main point(s) of
using the java bean.JavaBeans are normal objects that follow these conventions. Because they do, then you can access them through simplified means. For example, One way of having an object in session that contains data I want to print our might be:
<%@ page import="my.pack.ShoppingCart %>
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    session.setAttribute("cart", cart);
%>Then later where I want to print a total:
<% out.print(cart.getTotal() %>Or, if the cart is a JavaBean I could do this:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session"/>
Then later on:
<jsp:getProperty name="cart" property="total"/>
Or perhaps I want to set some properties on the object that I get off of the URL's parameter group. I could do this:
<%
ShoppingCart cart = session.getAttribute("cart");
if (cart == null) {
    cart = new ShoppingCart();
    cart.setCreditCard(request.getParameter("creditCard"));
    cart.setFirstName(request.getParameter("firstName"));
    cart.setLastName(request.getParameter("lastName"));
    cart.setBillingAddress1(request.getParameter("billingAddress1"));
    cart.setBillingAddress2(request.getParameter("billingAddress2"));
    cart.setZipCode(request.getParameter("zipCode"));
    cart.setRegion(request.getParameter("region"));
    cart.setCountry(request.getParameter("country"));
    pageContext.setAttribute("cart", cart);
    session.setAttribute("cart", cart);
}Or you could use:
<jsp:useBean id="cart" class="my.pack.ShoppingCart" scope="session">
<jsp:setProperty name="cart" property="*"/>
</jsp:useBean>The second seems easier to me.
It also allows you to use your objects in more varied cases - for example, JSTL (the standard tag libraries) and EL (expression language) only work with JavaBeans (objects that follow the JavaBeans conventions) because they expect objects to have the no-arg constuctor, and properties accessed/changed via getXXX and setXXX methods.

NUMBER Datatype
The NUMBER datatype stores zero as well as positive and negative fixed numbers with absolute values from 1.0 x 10-130 to (but not including) 1.0 x 10126. If you specify an arithmetic expression whose value has an absolute value greater than or equal to 1.0 x 10126, then Oracle returns an error. Each NUMBER value requires from 1 to 22 bytes.
Specify a fixed-point number using the following form:
NUMBER(p,s)
where:
p is the precision, or the total number of significant decimal digits, where the most significant digit is the left-most nonzero digit, and the least significant digit is the right-most known digit. Oracle guarantees the portability of numbers with precision of up to 20 base-100 digits, which is equivalent to 39 or 40 decimal digits depending on the position of the decimal point.
s is the scale, or the number of digits from the decimal point to the least significant digit. The scale can range from -84 to 127.
Positive scale is the number of significant digits to the right of the decimal point to and including the least significant digit.
Negative scale is the number of significant digits to the left of the decimal point, to but not including the least significant digit. For negative scale the least significant digit is on the left side of the decimal point, because the actual data is rounded to the specified number of places to the left of the decimal point. For example, a specification of (10,-2) means to round to hundreds.
Scale can be greater than precision, most commonly when e notation is used. When scale is greater than precision, the precision specifies the maximum number of significant digits to the right of the decimal point. For example, a column defined as NUMBER(4,5) requires a zero for the first digit after the decimal point and rounds all values past the fifth digit after the decimal point.
It is good practice to specify the scale and precision of a fixed-point number column for extra integrity checking on input. Specifying scale and precision does not force all values to a fixed length. If a value exceeds the precision, then Oracle returns an error. If a value exceeds the scale, then Oracle rounds it.
Specify an integer using the following form:
NUMBER(p)
This represents a fixed-point number with precision p and scale 0 and is equivalent to NUMBER(p,0).
Specify a floating-point number using the following form:
NUMBER
The absence of precision and scale designators specifies the maximum range and precision for an Oracle number.
And
2
NUMBER[(precision [, scale]])
Number having precision p and scale s. The precision p can range from 1 to 38. The scale s can range from -84 to 127
