Difference between dropdown index

Hi,
Pls tell me the dif between dropdown by index and dropdown by key?

Hi,
DRP BY INDEX is used to have the custom dropdowns. Based on some condition, if you want to fill the dropdown
dynamically then this is used.
DRPBY KEY this is usaually used when we have values at DOMAIN level as fixedvalues, VALUE table.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

Difference between sy-index & sy-tabix

Dear friends,
Please tell me the difference between sy-index & sy-tabix
Actually my problem is i don't know how to compare for example between first record'field n and second record'field n when u r in loop so i can take particular action based on result
on current recor
if possible send me sample code.
Regards;
Parag Gavkar.

SY-TABIX:
Current line in an internal table. With the following statements SY-TABIX is set for index tables. With hashed tables, SY-TABIX is not filled or it is set to 0.
- APPEND sets SY-TABIX to the index of the last table row, that is the total number of entries in the target table.
- COLLECT sets SY-TABIX to the index of the existing or appended table row. With hashed tables, SY-TABIX is set to 0.
- LOOP AT sets SY-TABIX to the index of the current table row at the beginning of every loop pass. After leaving a loop, SY-TABIX is set to the value it had before entering the loop. With hashed tables, SY-TABIX is set to 0.
- READ TABLE sets SY-TABIX to the index of the table row read. If no row is found with binary search while reading, SY-TABIX contains the index of the next-highest row or the total number of rows +1. If no row is found with linear search while reading, SY-TABIX is undefined.
- SEARCH itab FOR sets SY-TABIX to the index of the table row, in which the search string was found.
SY-INDEX:
SY-INDEX contains the number of loop passes in DO and WHILE loops, including the current loop pass.

What is the difference between creating index on cube and infopkg in PC

Hi All
I have process chain in which after executing infopkg(load data infopkg),creating index on cube i.e Object type is Cube ,for which execution time is 1 hour,then after (subsequent step ) again create index at this time object type is "infopkg"
execute infopkg for which time is 2 minnutes,what is the diffrence between these two,if i reome create index from cube i can save 1 hour time,I have to reveiew this
chain for performance,plese post me your thoughts,it's argent,your help will be heighly appreciatable.Thanks in advance.
regards
EA

By default once u use create index process type Object type has Infopackage - change it to Cube tech name.
If its Cube - Indexes will be deleted or created for all the date in the cube.

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.

Difference between Unique key and Unique index

Hi All,
I've got confused in the difference between unique index & unique key in a table.
While we create a unique index on a table, its created as a unique index.
On the other hand, if we create a unique key/constraint on the table, Oracle also creates an index entry for that. So I can find the same name object in all_constraints as well as in all_indexes.
My question here is that if during creation of unique key/constraint, an index is automatically created than why is the need to create unique key and then two objects , while we can create only one object i.e. unique index.
Thanks
Deepak

This is only my understanding and is not according to any documentation, that is as follows.
The unique key (constraint) needs an unique index for achieving constraint of itself.
Developers and users can make any constraint (unique-key, primary-key, foreign-key, not-null ...) to enable,disable and be deferable. Unique key is able to be enabled, disabled, deferable.
On the other hand, the index is used for performance-up originally, unique index itself doesn't have the concept like constraints. The index (including non-unique, unique) can be rebuilded,enabled,disabled etc. But I think that index cannot be set "deferable-builded" automatic.

Difference between indexes

Hi ,
What is difference between normal index and domain index?
Please help.
Thanks.

>
What is difference between normal index and domain index?
>
Domain indexes are custom indexes that you provide the code to manage: create, update, delete values.
Normal indexes are the indexes that Oracle makes available out-of-the-box as standard functionality.
If you need to index non-relational data or have unique indexing requirements (e.g. to index binary data) Oracle provides Data Cartridge functionality that allows you to extend Oracle to include your own indexing code.
The link to the Data Cartridge doc that marcusrangle provided gives the domain index definition at the top.
See Overview of Indextypes and Domain Indexes
>
Overview of Indextypes and Domain Indexes
A domain index is an index designed for a specialized domain, such as spatial or image processing. Users can build a domain index of a given type after the designer creates the indextype. The behavior of domain indexes is specific to an industry, a business function, or some other special purpose; you must specify it during cartridge development.

Difference b/w index and unique

Hi,
Difference b/w index and unique?

hi,
The optional additions UNIQUE or NON-UNIQUE determine whether the key is to be unique or non-unique, that is, whether the table can accept duplicate entries. If you do not specify UNIQUE or NON-UNIQUE for the key, the table type is generic in this respect. As such, it can only be used for specifying types. When you specify the table type simultaneously, you must note the following restrictions:
You cannot use the UNIQUE addition for standard tables. The system always generates the NON-UNIQUE addition automatically.
You must always specify the UNIQUE option when you create a hashed table.
INDEX:
An index can be considered a copy of a database table that has been reduced to certain fields. This copy is always in sorted form. Sorting provides faster access to the data records of the table, for example using a binary search. The index also contains a pointer to the corresponding record of the actual table so that the fields not contained in the index can also be read.
The primary index is distinguished from the secondary indexes of a table. The primary index contains the key fields of the table and a pointer to the non-key fields of the table. The primary index is created automatically when the table is created in the database
You can also create further indexes on a table in the ABAP Dictionary. These are called secondary indexes. This is necessary if the table is frequently accessed in a way that does not take advantage of the sorting of the primary index for the access.
Indexes speed up data selection from the database. They consist of selected fields of a table, of which a copy is then made in sorted order. If you specify the index fields correctly in a condition in the WHERE or HAVING clause, the system only searches part of the index (index range scan).
The system automatically creates the primary index. It consists of the primary key fields of the database table. This means that for each combination of fields in the index, there is a maximum of one line in the table. This kind of index is also known as UNIQUE.
If you cannot use the primary index to determine the result set because, for example, none of the primary index fields occur in the WHERE or HAVINGclauses, the system searches through the entire table (full table scan). For this case, you can create secondary indexes, which can restrict the number of table entries searched to form the result set.
You create secondary indexes using the ABAP Dictionary. There you can create its columns and define it as UNIQUE. However, you should not create secondary indexes to cover all possible combinations of fields.
Only create one if you select data by fields that are not contained in another index, and the performance is very poor. Furthermore, you should only create secondary indexes for database tables from which you mainly read, since indexes have to be updated each time the database table is changed. As a rule, secondary indexes should not contain more than four fields, and you should not have more than five indexes for a single database table.
If a table has more than five indexes, you run the risk of the optimizer choosing the wrong one for a particular operation. For this reason, you should avoid indexes with overlapping contents.
Secondary indexes should contain columns that you use frequently in a selection, and that are as highly selective as possible. The fewer table entries that can be selected by a certain column, the higher that columns selectivity. Place the most selective fields at the beginning of the index. Your secondary index should be so selective that each index entry corresponds to, at most, five percent of the table entries. If this is not the case, it is not worth creating the index. You should also avoid creating indexes for fields that are not always filled, where their value is initial for most entries in the table.
If all of the columns in the SELECT clause are contained in the index, the system does not have to search the actual table data after reading from the index. If you have a SELECT clause with very few columns, you can improve performance dramatically by including these columns in a secondary index.
What is the difference between primary index and secondary index?
http://help.sap.com/saphelp_47x200/helpdata/en/cf/21eb2d446011d189700000e8322d00/frameset.htm
A difference is made between Primary & Secondary indexes to a table. the primary index consists of the key fields of the table and a pointer to the non-keys-fields of the table. The Primary index is generated automatically when a table is created and is created in the datebase as the same times as the table. It is also possible to define further indexes to a table in the ABAP/4 dictionary, which are then referred to as Secondary indexes.

Difference bet cube indexes and dso indexes

hi,
1.can any tell me the difference between cube indexes and dso indexes?
if we have aggregates on the cube it improves the performce of the query created on it
2.so why to create indexes on the cube?
for creating indexes on the dso i right click on dso and click create indexes
it is asking two options
1.unique key 2.non unique
4.what is the functionality of these two?
i will assign points if ur answers clear my questions

The BW automatically defines multiple indexes on your cubes, based on the dimensions you have defined. You do not need to create any additional indexes on your Fact tables. It can somtimes be helpful to create a secondary index on dimension tables or master data tables depending on their size and the queries. There is not BW wkbench tool to do this, it usually requires a DBA in most shops.
Secondary indexes on DSO/ODS can help some queries substantially, again, depending on the data and the queries. You can define secondary indexes on DSO/ODS from the BW workbench.
Aggregates are another tool for query performance, by summarizing the data, it can reduce the number of rows that must be read by a query. Again, it dpends on the query and the data as to how much an aggregate helps.

What is the difference between Topic Keywords and Index File Keywords?

What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
RH9.0.2.271
I'm using Webhelp

Hi there
When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
<meta name="MS-HKWD" content="BOFFO" />
When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
Hopefully this helps... Rick

Difference between open loop and closed loop mode when finding the index on a stepper motor axis.

I have a test system which uses a PXI-7352 motion controller with a MID-7602 stepper motor drive to position a 200 step/revolution stepper motor with an attached 1000 line encoder. The MID-7602 is configured for 64 microsteps per step, giving 12,800 microsteps and 4000 encoder counts per revolution. The system is controlled using LabView 7.1 and NI-Motion 6.13. To home the motor, I've defined a sequence in MAX which first finds the reverse limit switch and then moves forward to the encoder index pulse.
When finding its reference in open loop mode, the system its reference at the same microstep each time. When findings its reference in closed loop mode, the system finds its reference somewhere within about a 20 microstep wide range.
I hope somebody out there with more experience with this controller can describe the difference between finding the encoder index in open loop mode and finding the encoder index in closed loop mode.
Thanks,
Mark Moss

Hello Mark,
I suspect that the behavior you are experiencing has today
with the resolution difference between your encoder and your
microstepping. Let me illustrate with an
example:
Example Setup
Stepper
Motor
NI
Motion Controller
10
steps per encoder pulse (Every 10 steps the controller gets an encoder
pulse, therefore positions 0-9 all appear to be 0 to the controller)
The
system has a maximum of 3 pull in moves set
Open Loop Scenario
The
system is commanded to go to position 9.
The
controller sends out 9 pulses.
The
motor moves to position 9.
Closed Loop Scenario
The
system is commanded to go to position 9.
The
controller sends out 9 pulses.
The
motor moves to position 9.
The
controller checks its position and sees that it is still at position 0
because it has not received an encoder pulse.
Because
the controller thinks it is still at position 0, it sends another 9 pulses
as its first pull in move.
The
motor moves to position 18.
The
controller checks its position and sees that it is at position 10 because
it has only received one encoder pulse.
Because
the controller thinks it is still at position 10, it sends1 reverse pulse
as its second pull in move.
The
motor moves to position 17.
The
controller checks its position and sees that it is at position 10 because
it has only received one encoder pulse.
Because
the controller thinks it is still at position 10, it sends and additional
single reverse pulse as its third pull in move.
The
motor moves to its final position of 16.
I believe something similar is happening with your
application as it looks for the index pulse.
Because the controller does not compensate for what it perceives as
position error in open loop mode, the motor always goes to the same commanded
position. In closed loop mode, the motor
is bouncing around inside the single index encoder pulse trying to find a
certain position.
There are several recommendations I can make towards
correcting this behavior. These
recommendations are in order of effectiveness:
Setup
your system so that there are more encoder counts per revolution than
steps per revolution.
Turn
off pull-in moves by setting them to 0 in MAX.
Use an
open loop configuration.
Play
around with the pull in window in MAX.
Regards,
Luke H
