How to merge work areas of same internal table

Hi Experts,
I have a requirement to merge two work areas into 3rd work area where all 3 belonging to same internal table like example below.
        person | activity | location |
wa1: 001     |    A       |              |
        person | activity | location |
wa2: 001     |              | xyz       |
after merging the value in wa3 should be as follows:
         person | activity | location |
wa3: 001      |    A       | xyz       |
I am looking for a ABAP command or FM to perform this task. Please help me on the same.
Many Thanks,
Vijay

Hello,
Try this:
Field-symbols: <lfs_wa1> type line of lit1,
 <lfs_wa2> type line of lit2.
sort lit2 by field1 ascending.
loop at lit1 assigning <lfs_wa1>.
 read table lit2 with key field1 = <lfs_wa1>-field1 assigning <lfs_wa2> binary search.
 clear wa3.
 wa3-field1 = <lfs_wa2>-field1.
 wa3-field2 = <lfs_wa2>-field2.
 wa3-field3 = <lfs_wa2>-field3.
 append wa3 to lit3.
endloop.
Use sorted internal tables, field symbols and binary search for better performance. In case when different fields in both work areas may be populated for each row, you need to implement some check and move logic inside loop instead of simple value assignment. I assume that the key value is always there for both tables you want to merge.
best regards,
Marcin

Value not moved to work are of the internal table

HI
I have one internal table declared with occurs 2500.
i am selecting the values from a z table into this internal table.
now i want to move the values in the table to another internal table for download.here except one field all the other fields are moving to the new internal table.When i debugged i could see the value in the internal table but its not getting moved to work area of that internal table (or the header line).
I could not see the value when i use itab[]-field in debugger mode instead when i use itab[1]-field i could see that field value.
please do suggest.

There is no need to move your data from one internal table to another with fixed structure. All you need to do is take each row's components skipping the column you don't want to download and concatenate this to some string. Then append to string table and download it. Sample:
"let's say your column is on 3rd place in the table
data l_row_string type string.
data lt_string_tab type table of string.
Loop at itab assigning <wa>.
do.
 check sy-index ne 3. "skip this column
 assign component sy-index of structure <wa> to <comp>.
 if sy-subrc = 0.
 CONCATENATE l_row_string <comp> INTO l_row_string SEPARATED BY cl_abap_char_utilities=>horizontal_tab.
 else.
 "no more component in row
 append l_row_string to lt_string_tab.
 clear l_row_string.
 exit.
 endif.
enddo.
endloop.
Now all you need is to downlaod your lt_string_tab as your text file (extension TXT).

Hi Ronny,
the alv output will display the sum at the last row.
for this functionality u have do this logic.
data: lw_fcat type slis_fieldcat_alv.
data: lt_fcat type slis_t_fieldcat_alv/
wa_fcat-fieldname = 'AMT1'.

How to do parallel processing with dynamic internal table

Hi All,
I need to implement parallel processing that involves dynamically created internal tables. I tried doing so using RFC function modules (using starting new task and other such methods) but didn't get success this requires RFC enabled function modules and at the same time RFC enabled function modules do not allow generic data type (STANDARD TABLE) which is needed for passing dynamic internal tables. My exact requirement is as follows:
1. I've large chunk of data in two internal tables, one of them is formed dynamically and hence it's structure is not known at the time of coding.
2. This data has to be processed together to generate another internal table, whose structure is pre-defined. But this data processing is taking very long time as the number of records are close to a million.
3. I need to divide the dynamic internal table into (say) 1000 records each and pass to a function module and submit it to run in another task. Many such tasks will be executed in parallel.
4. The function module running in parallel can insert the processed data into a database table and the main program can access it from there.
Unfortunately, due to the limitation of not allowing generic data types in RFC, I'm unable to do this. Does anyone has any idea how to implement parallel processing using dynamic internal tables in these type of conditions.
Any help will be highly appreciated.
Thanks and regards,
Ashin

How to make use of a global internal table in SAP BW during transfer rules

HI friends,
I am ABAP consultant working on some APO info cubes. I have an issue during the upload of planning area data into APO info cube.
Please help.
I am using a transfer routine to find the TECHWEEK from a data base table ZGC_CALWEEK based on the on the calender month and calender week.
Code I am writing is like below.
* FORM COMPUTE_/BIC/ZCALWEEK
* Compute value of InfoObject ZCALWEEK
* in communication structure /BIC/CSZT6DPPA
* Technical properties:
* field name = /BIC/ZCALWEEK

 ENDIF.
*$*$ end of routine - insert your code only before this line *-*
ENDFORM.
There are more than 50-80 million records that wil be transferred from planning area to info cube. The select statment is giving pathetic performance as this has to run 50-80 million times.
After adding the select statment to find the TECHWEEK it is taking 4 times the time that used to take before writing the select statment.
Is there a way that I can first fetch the data from ZGC_CALWEEK to one internal table and that internal table can be used using read statment during the transfer routine instead of writing select statement here.
Please help in this case?

Hi Ashutosh,
Thanks for the reply,
The structure of the ZGC_CALWEEK is as below. I have already created a secondary index on the table for this table for the fields APO WEEK and APO MONTH. This didn't help much on the performance.
I am also planning to keep the ZGC_CALWEEK database table to be fully buffered and this may definitely improve the performance but I need to reduce the data base hits as less as possible.
MANDT MANDT CLNT 3 0 Client
TECHWEEK ZTECHWEEK NUMC 6 0 Technical Week
FROMDATE_TECH DATUM DATS 8 0 Date
TODATE_TECH DATUM DATS 8 0 Date
APOWEEK /BI0/OICALWEEK NUMC 6 0 Calendar year / week
FROMDATE_APO DATUM DATS 8 0 Date
TODATE_APO DATUM DATS 8 0 Date
APOMONTH /BI0/OICALMONTH NUMC 6 0 Calendar year/month
The table ZGC_CALWEEK is in APO system, where the transfer rules are being executed.
As you mentioned START ROUTINE, In the start routine Can I create an internal table let's say GT_CALWEEK with structure ZGC_CALWEEK and pull all the records (I have a max of 2000 records in this table) from ZGC_CALWEEK to GT_CALWEEK and Can I used the same internal table GT_CALWEEK in the transfer routine to read the TECHWEEK from internal table.
Thank you very much again for you reply. Any help regarding this would be greatly appreciated.
Best regards,
Siva

2 different tables in the main window with same internal table data

Hi All,
can we have 2 diffterent tables with same internal table data into its work area in the main window.Is it possible or we will get any run time error.?
is it like having 2 nested loop with same internal table ?
ex : loop at itab1 into wa_itab.
loop at itab1 into wa_itab.
endloop.
endloop.
can we use like this?

Hi,
there will not be any error ...but what is the use of it...
do you need to have a controlled way of display ...of the data...
If so then you create another workarea in the global definitions of the same type and then use it...

How many SECONDARY INDEXES are created for CLUSTER TABLES?

how many SECONDARY INDEXES are created for CLUSTER TABLES?
please explain.

There seems to be some kind of misunderstanding here. You cannot create a secondary index on a cluster table. A cluster table does not exist as a separate physical table in the database; it is part of a "physical cluster". In the case of BSEG for instance, the physical cluster is RFBLG. The only fields of the cluster table that also exist as fields of the physical cluster are the leading fields of the primary key. Taking again BSEG as the example, the primary key includes the fields MANDT, BUKRS, BELNR, GJAHR, BUZEI. If you look at the structure of the RFBLG table, you will see that it has primary key fields MANDT, BUKRS, BELNR, GJAHR, PAGENO. The first four fields are those that all cluster tables inside BSEG have in common. The fifth field, PAGENO, is a "technical" field giving the sequence number of the current record in the series of cluster records sharing the same primary key.
All the "functional" fields of the cluster table (for BSEG this is field BUZEI and everything beyond that) exist only inside a raw binary object. The database does not know about these fields, it only sees the raw object (the field VARDATA of the physical cluster). Since the field does not exist in the database, it is impossible to create a secondary index on it. If you try to create a secondary index on a cluster table in transaction SE11, you will therefore rightly get the error "Index maintenance only possible for transparent tables".
Theoretically you could get around this by converting the cluster table to a transparent table. You can do this in the SAP dictionary. However, in practice this is almost never a good solution. The table becomes much larger (clusters are compressed) and you lose the advantage that related records are stored close to each other (the main reason for having cluster tables in the first place). Apart from the performance and disk space hit, converting a big cluster table like BSEG to transparent would take extremely long.
In cases where "indexing" of fields of a cluster table is worthwhile, SAP has constructed "indexing tables" around the cluster. For example, around BSEG there are transparent tables like BSIS, BSAS, etc. Other clusters normally do not have this, but that simply means there is no reason for having it. I have worked with the SAP dictionary for over 12 years and I have never met a single case where it was necessary to convert a cluster to transparent.
If you try to select on specific values of a non-transparent field in a cluster without also specifying selections for the primary key, then the database will have to do a serial read of the whole physical cluster (and the ABAP DB interface will have to decompress every single record to extract the fields). The performance of that is monstrous -- maybe that was the reason of your question. However, the solution then is (in the case of BSEG) to query via one of the index tables (where you are free to create secondary indexes since those tables are transparent).

Copy a certain row of data into the next row in a same internal table ??

HI, guys.
May i know how to copy a certain row of data into the next row in a same internal table ?? Bcz I plan to update a certain colum of data in the row just now into another value..
For example:-
*at first...
ebeln1   ebelp1   xblnr1
ebeln2   ebelp2   xblnr2
ebeln3   ebelp3   xblnr3
*after that, become...
ebeln1   ebelp1   xblnr1
ebeln2   ebelp2   xblnr2
ebeln2   ebelp2   xblnr4
ebeln2   ebelp2   xblnr5
ebeln3   ebelp3   xblnr3
Thanks in advance.

hi,
If you have this kind of requirement then you must be having 2 internal tables ,one existing data and 2nd from which you have to insert the records into 1st table.
so in this case,
loop at itab1.
v_index = sy-tabix.
loop at itab2 into wa where pri_key = itab1-pri_key.
v_index = v_index + 1.
insert wa into itab index v_index.
endloop.
endloop.
Using this code ,your data records similar to your 1st tables primary key records will get inserted into table.

How can i pass calculated value to internal table

and now i want to pass
one field ED1 which i has calculated separatly and i want to pass this value into iznew1
but error is coming that iznew1 is a table with out header line has no component like ED1.
so how can i pass calculated value to internal table iznew1,

When you declare your internal table , make an addtion occurs 0
eg . data : begin of iznew occurs 0 ,
                fields ...
   add the field here ed1.
           end of iznew.
now when you are calculating the value of ed1,
you can pass the corresponding value of ed1 and modify table iznew.
eg
loop at iznew.
iznew-ed1 = ed1.
modify iznew.
endloop.

Hi,
for example we have 3 internal tables
1> it_header 2>it_items 3>it_final (which contains all the header and item fields)
once it_header it_items are filled
loop at it_items.
read table it_header with key xyz = it_item-xyz.
if sy-subrc = 0.
here move all the header fields to it_final like below.
it_final -xfield = it_header-xfield.
endif.
here move all the item fields to it_final like below.
it_final -yfield = it_item-yfield.
append it_final.
clear it_final.
endloop.
now header and item fileds will be fillled in it_item

How to collect similar record from the internal table

I need to collect exact matched records from 1 internal table to another internal table by searching 5 fields. I need to have records which are exactly matched for 5 fields. i have written a code wich is mention below it gave me only similar records but not 100% matched record.. would you like to help me. any correction, suggetion,. Will be great help to me.

To get exact match of 5 records, do as follows.
Check whether internal table gives only one record or not after READ statement.If internal table gives more than one entry for READ then the results will be improper.
I think there is no need of READ statement on same internal table within LOOP. I commented the same in code.
sort i_bp_p by title initials name_last idnumber idtype f50code rbcode. "acc_num.
loop at i_bp_p into wa_i_bp_p.
*lv_tabix = sy-tabix.
*read table i_bp_p index lv_tabix into wa_i_bp_p.read table i_but0id into wa_but0id with key idnumber = wa_i_bp_p-idnumber
idtype = wa_i_bp_p-idtype binary search.
if sy-subrc = 0.
read table i_but000 into wa_but000 with key title = wa_i_bp_p-title
initials = wa_i_bp_p-initials
name_last = wa_i_bp_p-name_last binary search.
if sy-subrc = 0.
read table i_but0is into wa_but0is with key f50code = wa_i_bp_p-f50code
rbcode = wa_i_bp_p-rbcode binary search.
if sy-subrc = 0.
move-corresponding wa_i_bp_p to i_bp_p100.
append i_bp_p100.
endif.
endif.
endif.
endloop.
sort i_bp_p100 by partner.
loop at i_bp_p100.
write : /10 i_bp_p100-partner,
