Index

Hi,
I had this mssg and i followed the steps as posted by the experts here.
 Be aware of Note number 597909 when setting line item DataSources
Message no. GQPI 063
Diagnosis
You have successfully generated an extraction structure for the FI-SL line item table ZGLT1A.
Before implementing a DataSource that accesses the line items for table ZGLT1A, you need to create an additional, secondary index for this table in the data dictionary. This index can significantly speed up data access.
Procedure
Create a (non-unique) index for table ZGLT1A in the DDIC that includes the following fields:
RCLNT
RLDNR
CPUDT
CPUTM
You can find additional details about this in SAP Note number 597909.
this was done on R/3 and i did replicate this datasource and am trying to use the info source in an ODS i am wondering if i gotta to do anything while creating ODS too under the Indexes tab of the ODS?
is there any link for these two indexes???
Thankyou

No, no...
ODS index can be built only if you need to speed up specific situation in which you have to do reporting or select statement to retrieve info in some internal coding...
R/3 table index is instead very useful (and suggested at once by SAP itself) when you will perform the extraction process...
So, go on with only what you already do !
Bye,
Roberto

Which to use - Sy-index or sy-tabix ??

This is what i found out about SY-INDEX and SY-TABIX but which one to use when i want to delete a line of data from an internal table ? I tried both sy-index and sy-tabix and both works fine and returning the expected output for me but which one is better of to use ?
SY-TABIX :- For Internal Table, Current Line Index
SY-INDEX :- For Loops, Current Loop Pass
The below code is where i uses the Delete ..
LOOP AT dmg.
        CONCATENATE
               dmg-dmg00
               dmg-dmg01
               dmg-dmg02
               dmg-dmg03
               dmg-dmg04
               dmg-dmg07
               dmg-dmg08
               dmg-dmg09 INTO tli_down1 SEPARATED BY '*'.
        APPEND tli_down1. CLEAR tli_down1.
        DELETE dmg INDEX sy-index.
        EXIT.
      ENDLOOP.

Right. Just like what they said upstairs, sy-babix is the best choice.
One more thing is, if you want to concatenate fields of table dmg and append to tli_down1 on by one. You should not use EXIT after delete dmg.
In that case ,only one line can be appended into tli_down1 table.

Index's on cubes or Aggregates on infoobjects

Hello,
Please tell me if it is possible to put index's on cubes; are they automatically added or is this something I put on them?
I do not understand index's are they like aggregates?
Need to find info that explains this.
Thanks for the hlep.
Newbie

Indexes are quite different from aggregates.
An Aggregate is a slice of a cube which helps the data retrival on a faster note when a query is executed on a cube. Basically it is kind of a snapshot of KPI's and Business Indicators (Chars) which will be displayed as the initial query run result.
Index is a process which is inturn will reduce the query response time. While an object gets activated, the system automatically create primary indexes. Optionaly, you can create additional index called secondary indexes.Before loading data, it is advisable to delete the indexes and insert them back after the loading.
Indexes act like pointers for quickly geting the Data.When u delete it will delete indexes and when u create it will create the indexes.
When loading we delete Bcs during loading it has to look for existing Indexes and try to update so it will effect the Data load performence so we delete and create it will take less time when compared to updating the existing ones.
There is one more issue we have to take care if u r having more than 50 million records this is not a good practice insteah we can delete and create during week end when they r no users.

LIKE, LIKEC and Index usage

I've table that contains about 20 million rows, and I've created index for varchar2(100) column. It works well if I do
SELECT * FROM MY_TABLE WHERE MY_COL LIKE 'FOO%';
But if I change query to use LIKEC (to make unicode escaped strings work):
SELECT * FROM MY_TABLE WHERE MY_COL LIKEC 'FOO%';
I always get full table scan in explain plan.
I tried to use NVARCHAR, or index created by TO_NCHAR but I always end up hitting full table scan.
Should I create index some special way or do something else before I get index working?

Just a gut feeling : is the database using character semantics or byte semantics?
My gut feeling, after looking up the documentation, is it should be character semantics.
BTW: Not posting version info decreases the chance you get an adequate reply.

Index with "or" clause (BUG still exists?)

The change log for 2.3.10 mentions "Fixed a bug that caused incorrect query plans to be generated for predicates that used the "or" operator in conjunction with indexes [#15328]."
But looks like the Bug still exists.
I am listing the steps to-repro. Let me know if i have missed something (or if the bug needs to be fixed)
DATA

Index: node-element-equality-string for node {}:value
2 indexes found.
QUERY

query 'let $temp := fn:compare("test", "test") = 0
let $results := for $i in collection("test.dbxml")
where ($temp or $i/node[value = ("a")])
return $i
return <out>{$temp}{$results}</out>'
When $temp is true i expected the result set to contain both the records, but that was not the case with the index. It works well when there is no index!
Result WITH INDEX
dbxml> print
<out>true<node><value>a</value></node></out>
Result WITHOUT INDEX

INDEX vs TABIX

Hi,
Can some body explain the CLEAR difference between Sy-index and Sy-tabix. And one or two small examples. I am little bit confused.
Thanx.

Hi,
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
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.

ANY SY-INDEX REFLECT CHANGES WHEN CONTROL BREAK STATEMENT PROCESS

Dear Guru's,
                 I have a requirement where i have to move the values to variable when control break (AT END OF) process. So i want to move the values according to the end of Vendor so for that i want to know is there any sy-index available which reflects changes when Control break (AT end of) process.
LIKE Sy-subrc = 0 when select statement fetches record or sy-tabix is like counter for loop.
Hope to get reply soon.
Regards,
Himanshu Rangappa

Hi,
There is no system Fields for it.
But your requirement can be done with 'AT NEW' and 'AT END' statement.
Refer this sample example,
loop at otab.
    at new module.
      move otab-module to otab2-module.
    ENDAT.
      at END OF effort.
      sum.               "Do your calculations here
      move otab-count to otab2-count.
      append otab2.
    endat.
endloop.

ABAP-- diff between sy-sy-tabix and sy-index

Hi Guru's,
Pleae can anybody expalins me what is the difference between sy-tabix and sy-index(Loop Index) ?
Because in one case i am Modifyimg the internal table inside the do loop by giving sy-index ((Index of Internal Tables)(MODIFY scarr_tab INDEX sy-index FROM scarr_wa TRANSPORTING currcode. ) in the syntax and in other case inside loop statement i am modifyng same record by giving sy-tabix MODIFY scarr_tab INDEX sy-tabix FROM scarr_wa TRANSPORTING currcode.) in the syntax.
in both cases its working fine but i am not getting which one i have to use where to modify the internal table?
regards
SATYA

Hi Henry,
SY-INDEX is the value of the current iteration. It is applicable for the following programming constructs in ABAP -
DO...ENDDO.
WHILE...ENDWHILE.
SY-TABIX (TABle IndeX) is applicable to internal tables. If you scroll down in the link which Eddie has given, you will find a more detailed explanation for sy-tabix and which statements affect its value.

Anand Mandalika.

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.

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,

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 b/w sy-index and sy-tabix

hai all,
Could u explain the difference b/w sy-index and sy-tabix?
regards,
Selva

Hi,
sy-index - For Loops, Current Loop Pass.
sy-tabix - For Internal Table, Current Line Index in internal table.
sy-tabix is used at internal table operations (READ TABLE ... LOOP AT ...), sy-index is used at cycles (DO...n TIMES).
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.
it can be set by using the following:
1.append
2.collect
3.loop at
4. read
5.search
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:
SY-INDEX is used to describe the number of iteration with in the DO..ENDDO, WHILE ...ENDWHILE....
for example,
DO.
WRITE SY-INDEX.
IF SY-INDEX = 3.
EXIT.
ENDIF.
ENDDO.
it gives output as:
1 2 3

Raj.
