Standard versus sorted tables

Hi,
in SE30 (abap runtime analysis) i have tried to possible solutions for a DB access, and according to the performance tuning rules you should use sorted(or hashed) tables in stead of standard table, but in my case the runtime is almost equal. How is that possible ? Any explanations ?
Situation : table RSSELDONE, more than 80000 records
Code 1 with standard table - runtime 6.710.000 ms
data: i_tab type table of rsseldone,
      lwa like line of i_tab.
select * from rsseldone into table i_tab.
read table i_tab into lwa
with key rnr = 'REQU_3N57ZUZODOJ53FHTMO97BKDTH'.
Code 2 with sorted table - runtime 7.051.939 ms
data: i_stab type sorted table of rsseldone
          with non-unique key
               rnr
          initial size 0,
      lwa like line of i_stab.
select * from rsseldone into table i_stab.
read table i_stab into lwa
with table key rnr = 'REQU_3N57ZUZODOJ53FHTMO97BKDTH'.
Strange !

hi,
Standard Table - the most commonly used type of table. You can sort and resort this table anytime. You can have duplicate records in them. Recommend that when accessing these tables, you sort them by a key and then READ via a BINARY SEARCH - better performance. When you write to this table the record is "appended" to the end of the table. In order to maintain the sort sequence (if any) you must use the SORT command again.
Sorted table - this table has a defined sort sequence. You cannot resort. You can have duplicates. When you READ these tables, SAP automatically tries to use a BINARY SEARCH. Because you use a Binary Search, the retrieval time isexpodential to the number of records. When you write a record to this table the table is resorted.
Hashed Table - this table has a defined key. When you write to the table it uses a hashing algorithm to identify where the record is stored (think if this as writing the location of a page in an index of a book). When you READ this table the system looks up this "index" and retrieves the record. Because of this the retrieval time is constant. Writing to this type of table takes the most time as it needs to calculate the hashing algorithm.

mainly performance reason ,if you use sorted internal table then it will have good performance than standard intentable
The internal tables could be catogrised into two.
indexed : standard and sorted tables.
nonindexed: hash tables.
standard table: it is the one we use generally.In this the data is not sorted and the only thing we can do is just process the data with out any restriction on it.
sorted tables: it works in two different manner.
 Frist one: is similar to standard table but the only difference is the data will be filled in a particular manner either ascending or descending.
 Second one: u can also fill the table keeping any field as primary key.now the data will be filled based on that particular key.
Hash tables: u can use this when u want to fill your internal table avoiding the duplication of data.it never permits the duplicate record to be stored in a internal table
Thanks

COLLECT: Which table is better to use - STANDARD or SORTED?

Hello Performance gurus,
I read this curious fact about COLLECT statement:
In standard tables that are filled using COLLECT only, the entry is determined by a temporary hash administrator. The workload is independent of the number of entries in the table. The hash administrator is temporary and is generally invalidated when the table is accessed to be changed. If COLLECT statements are specified after an invalidation, a linear search of all table rows is performed. The workload for this search increases in a linear fashion in relation to the number of entries.
In sorted tables, the entry is determined using a binary search. The workload has a logarithmic relationship to the number of entries in the table.
In hashed tables, the entry is determined using the hash administrator of the table and is always independent of the number of table entries.
So does this mean if we're populating a table using COLLECT we should prefer STANDARD over SORTED(due to the HASH administration)? Is there any performance overload while setting up the temporary hash administrator for STANDARD tables?
Please enlighten me.
BR,
Suhas

Actually I have just noticed I already had created a test program for this somewhere in the past.
Here are the results:
STANDARD            1.091.295
SORTED              3.159.771
HASHED                994.101
If for the STANDARD table you somehow destroy the hash administration (in this case it was done in the beginning by APPENDing one record):
STANDARD            2.255.905
SORTED                 14.013
HASHED                  8.022
(this 2nd execution was with less rows that the 1st execution, otherwise for the standard table it would take too long).
So this does prove that standard tables can be faster than sorted tables in that special case, but again I would not rely on that.

Memory and performance when copying a sorted table to a standard table

Hello,
As you all probably know, it's not possible to use a sorted table as a tables parameter of a function module, but sometimes you want to use a sorted table in your function module for performance reasons, and at the end of the function module, you just copy it to a standard table to return to the calling program.
The problem with this is that at that moment, the contents of the table is in memory twice, which could result in the well known STORAGE_PARAMETERS_WRONG_SET runtime exception.
I've been looking for ways to do this without using an excessive amount of memory and still being performant. I tried four methods, all have their advantages and disadvantages, so I was hoping someone here could help me come up with the best way to do this. Both memory and performance are an issue.
Requirements :
- Memory usage must be as low as possible
- Performance must be as high as possible
- Method must work on all SAP versions from 4.6c and up
So far I have tried 3 methods.
I included a test report to this message, the output of this on my dev system is :
Test report for memory usage of copying tables
table1[] = table2[]
Memory :    192,751 Kb
Runtime:    436,842

I've had another idea:
Create a RFC function like this (replace SOLI_TAB with your table types):
FUNCTION Z_COPY_TABLE .
*"*"Lokale Schnittstelle:
*" IMPORTING
*"     VALUE(IT_IN) TYPE SOLI_TAB
*" EXPORTING
*"     VALUE(ET_OUT) TYPE SOLI_TAB
et_out[] = it_in[].
ENDFUNCTION.
and then try something like this in your program:
DATA: gd_copy_done TYPE c LENGTH 1.
DATA: gt_one TYPE soli_tab.
DATA: gt_two TYPE soli_tab.
PERFORM move_tables.
FORM move_tables.
CLEAR gd_copy_done.
CALL FUNCTION 'Z_COPY_TABLE'
    STARTING NEW TASK 'ztest'
    PERFORMING copy_done ON END OF TASK
    EXPORTING
      it_in = gt_one[].
CLEAR gt_one[].
WAIT UNTIL gd_copy_done IS NOT INITIAL.
ENDFORM.
FORM copy_done USING ld_task TYPE clike.
RECEIVE RESULTS FROM FUNCTION 'Z_COPY_TABLE'
   IMPORTING
     et_out        = gt_two[].
gd_copy_done = 'X'.
ENDFORM.
Maybe this is a little bit faster than the Memory-Export?

Standard and sorted itab

what is the diff between standard and sorted itab

Hi Abhay,
check the following explanation.
Standard tables
This is the most appropriate type if you are going to address the individual table entries using the index. Index access is the quickest possible access. You should fill a standard table by appending lines (ABAP APPENDstatement), and read, modify and delete entries by specifying the index (INDEX option with the relevant ABAP command). The access time for a standard table increases in a linear relationship with the number of table entries. If you need key access, standard tables are particularly useful if you can fill and process the table in separate steps. For example, you could fill the table by appending entries, and then sort it. If you use the binary search option (BINARY) with key access, the response time is logarithmically proportional to the number of table entries.
Sorted tables
This is the most appropriate type if you need a table which is sorted as you fill it. You fill sorted tables using the INSERTstatement. Entries are inserted according to the sort sequence defined through the table key. Any illegal entries are recognized as soon as you try to add them to the table. The response time for key access is logarithmically proportional to the number of table entries, since the system always uses a binary search. Sorted tables are particularly useful for partially sequential processing in a LOOP if you specify the beginning of the table key in the WHEREcondition.
Hope this helps.

Sorted Table - tabix issue

All,
I have the following code While executing system is pointing to sy-tabix, but the data I am getting in the READ statement is from last record in the internal table
report z_9699_30.
tables : eket.
types : begin of ty_eket.
        include structure eket.
types: end of ty_eket.
data: wa_eket                 type ty_eket.
data: it_eket                 like sorted table of wa_eket
                              with unique key primary_key
                              components ebeln ebelp etenr
                              with non-unique sorted key secondary_key
                              components ebeln ebelp.
parameters: p_ebeln like eket-ebeln.
parameters: p_ebelp like eket-ebelp.
select * from eket into table it_eket
      where ebeln eq p_ebeln.
      read table it_eket into wa_eket with table key secondary_key
               components ebeln = p_ebeln
                          ebelp = p_ebelp.
Please copy and execute this by giving EBELN and EBELP from EKET
Please make sure while selecting from EKET please select data of multiple records available for same EBELP ie llike
Here below PO # 4500000003 and for Item # 00030 is have multiple records
Here in selection screen by giving PO # as 4500000003 (EBELN) Item # as 00030 (EBELP) , then in the above READ statement system giving SY-TABIX as 3 but if you see the WA_EKET-ETENR is showing 2 instead of 1. This is where is the issue is
EBELN
EBELP
ETENR
Header 4
4500000003
00010
1
4500000003
00020
1
4500000003
00030
1
4500000003
00030
2

Now execute some
MOVE sy_tabix TO lv_index.
READ TABLE it_eket INTO wa_eket
      INDEX lv_index USING KEY secondary_key.
BREAK-POINT.
READ TABLE it_eket INTO wa_eket
      INDEX lv_index USING KEY primary_key.
BREAK-POINT.
and conclude yourself on the meaning of life index with two different keys defined...
Regards,
Raymond
PS: Reference in online help for sy-tabix now
Note that the sy-tabix system field is populated by the assigned secondary index, if sorted secondary keys are used. If this value is used for the subsequent index access to the internal table, the same table index must be explicitly used here. If used implicitly, the value would be interpreted as a primary index.

Hello Durga,
from the error what I understood is lt_key_values is a sorted table and you are trying append a new line to it. Incase of sorted table you need to use the INSERT statement and not the APPEND statement.
INSERT lw_key_value INTO table lt_key_values.

How to get standard view or table for the standard inforsource

Hi all:
According to business reqirement, we are going to use standard inforsource 0CO_OM_CCA_10,
we need to know the standard view or table in order to corresponding DataSource?
could you please tell me how to get the standard view or table or DataSource?
Couldn't thank you more!

Hi Sony,
Goto RSA1>BI content installation>goto objects>double click on the Infosource>then a pop-up comes search for that infosource-->select it and click on transfer
Before that in the right side of the tab select the grouping as "Before and afterwards of the dataflow" and collection as automatic.
then you get all the datasource/cubes and all the object related to the infosource.
OR another option is-->
Goto RSA6 in the R/3 and search for the datasource with the name "0CO_OM_CCA_10" (don't forget to expand all the tree structure in RSA6)
then goto that datasource and double click on the datasource then you will get the Extract structure of that datasource.
double click on the extract structure then you may get the View name also.
hope this helps...

You are passing by reference with CHANGING.

Info. / Doc. on Changes to Standard SAP Program, Tables, Fields in SAP 6.0

We are in the process of upgrading our SAP from 4.6c to 6.0 and I am looking for a document or white paper that summarizes changes to Standard SAP Programs, Tables/Fields, Function Modules etc.. from what used to be in SAP 4.6c to what it is in SAP 6.0. I am not sure if such a comprehensive document exists or is posted in the forum.
Any help or information in this regard will be highly appreciated.
Thanks

Hi Ram,
<< We are in the process of doing our technical upgrade from SAP 4.6c to 6.0. I am looking for a white paper or documentation listing the changes made to the standard SAP Programs, Tables, Fields, Function Modules etc. from Rel. 4.6c to 6.0. >>
Do you want to know what custom changes were done to SAP standard objects in your system or do you want to know what changes SAP did from 4.6c to ECC6.0.
There is no white paper or documentation to find out custom changes made to SAP standard objects. but there were many tools in the market to find out and tell what changes were done to sap standard objects in your system.
Your question seems ambiguous please clear it.
Thanks,
Kiran.
