Sorting of Dyanmic internal table

Hi Gurus,
I am having a dynamic internal table (it_mat) having fields matnr uname field1,field2,field3 and field4.
the field is upto fieldN.
I want my table to sorted by this manner
Sort it_mat by field4 field3 field2 field1.
Sort it_mat by fieldN field(N-1)...field1.
Please help me in to get this in dynamic manner.

You can try something like this:
types : begin of ty_comps.
 include type abap_compdescr.
types: srl type i.
types : end of ty_comps .
data: lt_comps type standard table of ty_comps,
 la_comps type ty_comps.
data: l_sort type standard table of char30 with header line.
loop at lt_tot_comp into la_comp. " LT_TOT_COMP contains all my components
 move-corresponding la_comp to la_comps.
 la_comps-srl = sy-tabix.
 append la_comps to lt_comps.
 clear la_comps.
endloop.
sort lt_comps by srl descending.
loop at lt_comps into la_comps.
 l_sort = la_comps-name.
 append l_sort.
endloop.
sort <f_tab> by (l_sort).
You can find the entire code which I have used to create a dynamic table at: [Dynamic Internal Table Creation|http://help-abap.blogspot.com/2008/09/dynamic-internal-table-creation.html]

there is no restriction to sort by any TYPE. u ve the freedom to sort on any TYPE of fields.
sort itab by ascending / descending F1 F2 F2.

What are dyanmic internal tables and what s the exact use of forall entries

what are dyanmic internal tables and what s the exact use of forall entries?

hi,
dynamic internal table.
http://searchsap.techtarget.com/tip/1,289483,sid21_gci912390,00.html
http://www.sap-img.com/ab030.htm

FOR ALL ENTRIES is an effective way of doing away with using JOIN on two tables.
You can check the below code -
SELECT BUKRS BELNR GJAHR AUGDT
FROM BSEG
INTO TABLE I_BSEG
WHERE BUKRS = ....
SELECT BUKRS BELNR BLART BLDAT
FROM BKPF
INTO TABLE I_BKPF
FOR ALL ENTRIES IN I_BSEG
WHERE BUKRS = I_BSEG-BUKRS
AND BELNR = I_BSEG-BELNR
AND BLDAT IN SO_BLDAT.
*******************************8
look another example
what is the use of FOR ALL ENTRIES
1. INNER JOIN
DBTAB1 <----
> DBTAB2
It is used to JOIN two DATABASE tables
having some COMMON fields.
2. Whereas
For All Entries,
DBTAB1 <----
> ITAB1
is not at all related to two DATABASE tables.
It is related to INTERNAL table.
3. If we want to fetch data
from some DBTABLE1
but we want to fetch
for only some records
which are contained in some internal table,
then we use for alll entries.
1. simple example of for all entries.
2. NOTE THAT
In for all entries,
it is NOT necessary to use TWO DBTABLES.
(as against JOIN)
3. use this program (just copy paste)
it will fetch data
from T001
FOR ONLY TWO COMPANIES (as mentioned in itab)
4
REPORT abc.
DATA : BEGIN OF itab OCCURS 0,
bukrs LIKE t001-bukrs,
END OF itab.
DATA : t001 LIKE TABLE OF t001 WITH HEADER LINE.
itab-bukrs = '1000'.
APPEND itab.
itab-bukrs = '1100'.
APPEND itab.
SELECT * FROM t001
INTO TABLE t001
FOR ALL ENTRIES IN itab
WHERE bukrs = itab-bukrs.
LOOP AT t001.
WRITE :/ t001-bukrs.
ENDLOOP.
Hope this helps!

TOP OF PAGE printing according to SORT - ALV main internal table

Hi guys
I manage to solve my previous issues but 1 minor problem here
Lets say I have an itab which has 3 records
Sales Order | Purchase No, | Distributor
1 | 123 | abc
1 | 123 | abc
2 | 456 | TGIF
I'm using FM REUSE_ALV_BLOCK_LIST_APPEND to display the ALV
its working for the main INTERNAL TABLE but when it comes to top of page, it doesn't follow the sort
I want it to print
Sales Order: 1
Purchase No: 123
Distributor: abc
TABLE 1
Sales Order: 2
Purchase No: 456
Distributor: TGIF
TABLE 2
But now its printing
Sales Order: 1
Purchase No: 123
Distributor: abc
TABLE 1
Sales Order: 1
Purchase No: 123
Distributor: abc
TABLE 2
Sales Order: 2
Purchase No: 456
Distributor: TGIF
TABLE <empty table>
My codes was working previously but its not longer the same.
READ TABLE it_report INTO l_report INDEX SY-tabix

Can anyone help me out here? How do I make it print just like the SORT for ALV?

Refresh the work areas then it work fine

Regarding the sorting of the internal table

hi,
this is my requirement
iam having an internal table itab and it consists of the date field s_date.
i have to sort the internal table in the descending order of the s_date.
please provide me the code for this.
thanks in advance

Hi Surya,
U can use this code
SORT ITAB BY S_DATE DESCENDING.
itab----internal table
S_date--Field name
By default the sorting is done ascending you dont have to specify.
Thanks

Differences between Standard , sorted and hashed internal tables

Can any body please tell me what are the main Differences between
1) Standard internal table
2) Hashed internal table
3) Sorted internal table
Please give me a clear idea about these Three.
Thanks
Prabhudutta

Hi,
Standard Internal Tables
Standard tables have a linear index. You can access them using either the index or the key. If you use the key, the response time is in linear relationship to the number of table entries. The key of a standard table is always non-unique, and you may not include any specification for the uniqueness in the table definition.
This table type is particularly appropriate if you want to address individual table entries using the index. This is the quickest way to access table entries. To fill a standard table, append lines using the (APPEND) statement. You should read, modify and delete lines by referring to the index (INDEX option with the relevant ABAP command). The response time for accessing a standard table is in linear relation to the number of table entries. If you need to use key access, standard tables are appropriate if you can fill and process the table in separate steps. For example, you can fill a standard table by appending records and then sort it. If you then use key access with the binary search option (BINARY), the response time is in logarithmic relation to
the number of table entries.
Sorted Internal Tables
Sorted tables are always saved correctly sorted by key. They also have a linear key, and, like standard tables, you can access them using either the table index or the key. When you use the key, the response time is in logarithmic relationship to the number of table entries, since the system uses a binary search. The key of a sorted table can be either unique, or non-unique, and you must specify either UNIQUE or NON-UNIQUE in the table definition. Standard tables and sorted tables both belong to the generic group index tables.
This table type is particularly suitable if you want the table to be sorted while you are still adding entries to it. You fill the table using the (INSERT) statement, according to the sort sequence defined in the table key. Table entries that do not fit are recognised before they are inserted. The response time for access using the key is in logarithmic relation to the number of
table entries, since the system automatically uses a binary search. Sorted tables are appropriate for partially sequential processing in a LOOP, as long as the WHERE condition contains the beginning of the table key.
Hashed Internal Tables
Hashes tables have no internal linear index. You can only access hashed tables by specifying the key. The response time is constant, regardless of the number of table entries, since the search uses a hash algorithm. The key of a hashed table must be unique, and you must specify UNIQUE in the table definition.
This table type is particularly suitable if you want mainly to use key access for table entries. You cannot access hashed tables using the index. When you use key access, the response time remains constant, regardless of the number of table entries. As with database tables, the key of a hashed table is always unique. Hashed tables are therefore a useful way of constructing and
using internal tables that are similar to database tables.

Sort Internal table based on another internal table

Hello All,
My Requirement is :
I have two internal tables itab1 and itab2. itab1 has partner_number along with some more fields/columns. Based on the partner_numbers of the itab1 i write a query to get the values for partner_last_name and central_block_flag from the table but000 and i fill these values into a new itab2.
Sort itab2 by partner_last_name and central_block.
Now how do I sort itab1 based on the sorted itab2-partner_number. I need to have itab1 sorted similar to the order in the itab2.
How do i do this?
Please let me know if you need more details.Looking forward for your support.
Regards,
Harish P M

Hello Micky,
Thank you for your early reply.
I have this scenario wherein i need to sort a existing internal table itab1 of type 'bapibus1006_relations' based on the 'Partner last name ' and 'Inactive/Active Flag'. These two fields are not available in this itab1 and so i need to create itab2 after a query on table but000.
Sorting itab2 is , first sort itab2 based on the 'Active flag' and then sort this itab2 again by 'Partner last name'(ascending order).
Finally when i get my sorted itab2 i would have to ensure that my objective of sorting itab1 is obtained.
I guess i sound better now.
Would be helpful if you could reply.

Sorting Order for SAP Tables in DB2 database

Dear Experts -
ISSUE: When an ABAP program selects data from the DB into an internal
table, it is changing the way the data is sorted. In other words, the
internal table data is in a different sort order than what is in the
DB. It is not working this way in all other non-production systems
(DEV, QAS, SAX, etc).
Temporary solution for the programs that have been identified as
impacted: Use the ABAP Command 'sort' on the internal table.
Permanent solution needed : Since it is impossible to identify all
of the programs that will be impacted, we need PRD to work like DEV,
QAS, SAX, etc. when selecting data into internal tables. The data
should be in the same order as it is in the DB (sorted by the key).
ADDITIONAL INFO: DB2 storage disks crashed a day before. H/W team recovered everything. We are facing this only after the recovery.
Thanks,
Dinesh

can you please check in your code if the sql that is being sent has an order by clause .
Please let us know the SQL statements that is basically used to fill up the internal table.
When data is fetched from the database, it is not sorted always. Probably you had a clustered index on the tables and the clustering is not there now.

Division of internal table records

Dear all
How can I observe that how many record my internal table got record and how can I divide into by lines
for ex.
 SELECT SINGLE pvprs FROM ckmlcr INTO sum_pvprs-pvprs
 WHERE poper EQ s_poper AND
 kalnr = itab2-kalnr AND
 bdatj = itab2-bdatj AND
 curtp = itab2-curtp.
 IF sy-subrc = 0.
 APPEND sum_pvprs.
I want to get arithmetic range of this sum_pvprs-pvprs
Actually I want to get number of lines and their summations
pvprs1= 10 pvprs=20 pvprs=30 and then
after I got this results 102030 = 60 /3 =20 I need this operation.
All the best
Message was edited by: yusuf tunay çilesiz

I am not sure what do you mean by arithmetic range...if you mean min and max numbers you can use the below logic.
SELECT SINGLE pvprs FROM ckmlcr INTO sum_pvprs-pvprs
WHERE poper EQ s_poper AND
kalnr = itab2-kalnr AND
bdatj = itab2-bdatj AND
curtp = itab2-curtp.
IF sy-subrc = 0.
APPEND sum_pvprs.
1. you can simply sort the sum_pvprs internal table...on pvprs first ascending and than descending to get the min and max numbers by reading the first record of the internal table.
REad table sum_pvprs index 1.
2. you can have two variables lmin and lmax and initialise the same before you append statement.
if sum_pvprs-pvprs > lmax.
lmax = sum_pvprs-pvprs.
endif.
if sum_pvprs-pvprs < lmin.
lmin = sum_pvprs-pvprs.
endif.
Sum and Average.
SELECT SINGLE pvprs FROM ckmlcr INTO sum_pvprs-pvprs
WHERE poper EQ s_poper AND
kalnr = itab2-kalnr AND
bdatj = itab2-bdatj AND
curtp = itab2-curtp.
IF sy-subrc = 0.
l_sum = sum_pvprs-pvprs + l_sum.
APPEND sum_pvprs.
ENDSELECT.
DESCRIBE TABLE sum_pvprs LINES lrec.
lavg = l_sum / lrec.

Create dynmic deep internal table

Dear all,
is it possible to create a dynamic internal table which has a deep structure. The catch here is that component tables of the main internal table will determined dynamically.
thanks a lot!!!
Navjot

Hi Navjot,
Dyanmic internal table with deep structure is specially useful when we have to create an ALV with Colors or Style etc. Since we have CL_ABAP_TABLEDESCR class from RTTS, it is also possible to create a dynamic internal table with the deep structure. To create an internal table with deep structure, we need to first get the object definition of the table type. Than we have to add that as a component of our table definition and that's it.
Try this :
*& Report ZNP_DYNAMIC_DEEP_TABLE.
*& Shows how to create dynamic internal table with deep strcuture
*& which can be used in the ALV to have Sytle table, Color table
* 2.1 Creating the Deep strcuture field
DATA: lo_tab TYPE REF TO cl_abap_tabledescr.
lo_tab ?= cl_abap_typedescr=>describe_by_name( 'LVC_T_SCOL' ).
la_comp-name = 'COLOR_TAB'.
la_comp-type = lo_tab.
APPEND la_comp TO lt_tot_comp.
CLEAR: la_comp.

How to find min and max of a field from sorted internal table

Hi,
I have sorted Internal Table by field f1.
How do I find max and min value of f1.
For min value of f1 I am using,
READ TABLE IT1 INDEX 1.
IT1-F1 = MIN.
Is this correct? And how do I find the max value of f1 from this table.
Thanks,
CD

Yes, that is right, and you can get the max like this.
data: lv_lines type i.
* get min
READ TABLE IT1 INDEX 1.
MIN = IT1-F1.
* get max
lv_lines = lines( it1 ).
read table it1 index lv_lines.
MAX = IT1-F1.

Sort the internal table based on the vendor field

hello experts,
I am stuck with a small problem...
I am uploading the data for partner association for vendors through lsmw BI program.
I am collecting all the records in the end of trasaction and downloading all those records on to the apps server.
I declared one internal table as
TYPES: BEGIN OF type_erecord,
 mesg(1000) TYPE c,
 END OF type_erecord.
DATA: t_precord type standard table of type_erecord initial size 0,
 w_precord type type_erecord.
I am concatenating all the fields and moving to the internal table..
concatenate zvendor_master-source zvendor_master-lifnr blf00-lifnr
 zvendor_master-lname zvendor_master-parvw
 zvendor_master-psource zvendor_master-pname
 zvendor_master-lifn2 bwyt3-lifn2
 zvendor_master-ekorg zvendor_master-werks
 w_PLANT-muplant zvendor_master-defpa
 v_message
 into w_precord-mesg separated by c_pipe.
 append w_precord to t_precord.
now at the end I have to sort this internal table t_precord based on blf00-lifnr
can any one guide me how to do it
Thanks for your anticipation
Nitesha

OK...
Than you can create one more table and do the process of sorting and than put data into the final table.

SORT INTERNAL TABLE USING NON KEY OF THE INTERNAL TABLE

HI,
i have one query for the cdpos table of abap.
What i am looking is i want the latest CHANENR of the cdpos for that
objectid and tabname and fname in my internal table.
what i thought of doing was to sort my internal table with objectid changnr tabname fname in descending order
and than use delete adjacent duplicates command
BUt that is not sorting based on all field , its sorting on changnr only
please let me know what can i do

no, that is not what i am looking at,

this is my debug output after sorting on objectid changenr tabname fname in descending
i wanted line 2nd to be at last so when i use delete adjacent command i can get 2 line item i.e 1st and 2nd line ...

Date sorting in internal table

Dear Friends
 I wish to know how i perform the date operations in internal table... I am looking for the most recent record from the internal table for that i am supposed to look at chdate and chtime fields gives me the information on most corrently changed record... if in the case of the record which is there but not changed to determin the its most currentness i must look at the crdate and crtime..so i have the code for that which works perfectly nice without the crdate and crtime... if i insert the crdate and crtime it gives me the only those records which are most currently chnaged according to chdate and chtime...would you like to help me in this regards, I am giving you the code here.. any suggestion or changes will be great help of mine... thanking you,,,,
