Dynamic programming by defining one structure

Dear all,
I have a problem to define a dynamic programm. Its easyer to show you the coding:
PERFORM my_perform TABLES lt_vbak.
PERFORM my_perform TABLES lt_vbap.
PERFORM my_perform TABLES lt_bkpf.
FROM my_perform TABLES pt_any_table.
LOOP AT pt_any_table ASSIGNING <fs_any_structure>.
ENDLOOP.
ENDFORM.
My problem is to define <fs_any_structure>. I want to do only one loop for each tables who coming throw the PERFOM.
How can I define the <fs_any_structure> (<fs_any_structure> TYPE ANY???). And its possible to get the structure of the individuell table like this coding?
Thank u very much

Hi,
Try this way.
PERFORM my_perform TABLES it_vbak USING wa_vbak.
PERFORM my_perform TABLES it_vbap USING wa_vbap.
PERFORM my_perform TABLES it_bkpf USING wa_bkpf.
FORM my_perform TABLES pt_any_table USING pt_any_wa.
LOOP AT pt_any_table INTO pt_any_wa.
ENDLOOP.
ENDFORM.
Hope this may help you.

Smart Varghese

How to create dynamic context based on a structure defined in the program?

Hi Experts,
         I need to create a dynamic context based on a structure wa_struc which i have define programatically.
When I pass wa_struc to structure_name parameter of create_nodeinfo_from_struc, i get a runtime error:
"Parameter STRUCTURE_NAME contains an invalid value wa_struc."

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :
The following error text was processed in the system PET : Line types of an internal table and a work area not compatible.
The error occurred on the application server FMSAP995_PET_02 and in the work process 0 .

Here's how to use DYNAMIC tables for almost any structure (4.6C onwards)

Hi guys
I'm describing a feature here that has been around since 4.6C that is not really well known but can really simplfy programming where you need to get data into some sort of internal table and then display it either as a classical list or as al ALV grid.
This feature is RTTI which allows you to retrieve your structure, build a dynamic FCAT (Field catalog) and a Dynamic table.
Here's a really quick little program which reads 200 entries from VAPMA into a dynamic table. Any structure will work if you use the code sample shown.
To pass it to an ALV GRID is then really simple as you've already got the Field Catalog, Table and Data.
The method I'm showing below will work for almost ANY structure you care to name whether or not the fields are in the data dictionary.
I create a dynamic FCAT and dynamic table based on the FCAT and then populate it.
You can create field catalogs dynamically quite simply by using the new RTTI facility available from 4.6C onwards.
(From here it's only a small step to dynamic tables and EASY ALV grid displays)
Example to create dynamic FCAT and table and populate it with 200 entries from VAPMA
PROGRAM ZZ_BUILD_FLDCATALOG.
tables: vapma.
Define any structure
types: begin of s_elements,
vbeln type vapma-vbeln,
posnr type vapma-posnr,
matnr type vapma-matnr,
kunnr type vapma-kunnr,
werks type vapma-werks,
vkorg type vapma-vkorg,
vkbur type vapma-vkbur,
status type c,
end of s_elements.
end of your structure
data lr_rtti_struc type ref to cl_abap_structdescr .
data:
zog like line of lr_rtti_struc->components .
data:
zogt like table of zog,
wa_it_fldcat type lvc_s_fcat,
it_fldcat type lvc_t_fcat ,
dy_line type ref to data,
dy_table type ref to data.
data: dref type ref to data.
field-symbols: <fs> type any,
<dyn_table> type standard table,
<dyn_wa>.
*now I want to build a field catalog
*First get your data structure into a field symbol
create data dref type s_elements.
assign dref->* to <fs>.
lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( <fs> ).
zogt[] = lr_rtti_struc->components.
Now build the field catalog. zogt has the structure in it from RTTI.
loop at zogt into zog.
clear wa_it_fldcat.
wa_it_fldcat-fieldname = zog-name .
wa_it_fldcat-datatype = zog-type_kind.
wa_it_fldcat-inttype = zog-type_kind.
wa_it_fldcat-intlen = zog-length.
wa_it_fldcat-decimals = zog-decimals.
wa_it_fldcat-coltext = zog-name.
wa_it_fldcat-lowercase = 'X'.
append wa_it_fldcat to it_fldcat .
endloop.
Let's create a dynamic table and populate it
call method cl_alv_table_create=>create_dynamic_table
exporting
it_fieldcatalog = it_fldcat
importing
ep_table = dy_table.
assign dy_table->* to <dyn_table>.
create data dy_line like line of <dyn_table>.
assign dy_line->* to <dyn_wa>.
select vbeln posnr matnr kunnr werks vkorg vkbur
up to 200 rows
from vapma
into corresponding fields of table <dyn_table>.
from here you can pass your table to a GRID for display etc etc.
Cheers
Jimbo

Thanks for the info.
I went to their web site and also Googled.
I found a great review on their photographer's books on nikonians.org
They use an HP/Indigo Ultrastream 3000 digital offset press for all hardcover books, which is GREAT!
I did sign up and requested the 45 day trial "photographer" account.
I am curious if Shared Ink offers a size that matches the ONLY current book size from Aperture, the odd 8.5x11.
In the above review, I saw that Shared Ink offers a 12x12 book.. very nice! Except you will need to design that one in CS2
So then, all that Apple really needs to do is simply add the ability to select/create custom book sizes. Then we don't need a printing service from Apple, as there are plenty of options out there, and more arriving on the market each month!

Problem with Self defined info structure.

Hi All,

steps to create own infostructure by copying standard infostructure.
steps.... 1) First Create your own info structure using menu path SPRO> Logistics general > LIS > Logistics data warehouse > Data basis > information structure > maintain self defined ino structure Here create a New stucture called S901 (Follow Custom defined structure naming conventions) for application 07, by copying S115 .
Once inside this Choose the Charateristic button below and CHOOSE SELECTION LIST.
This will popup a list of fields that can be added to the structure for analysis per field catalogue.
Navigate to the notification Object field catalog to select the Order number.
Select other field as appropriate from other field catalog and copy them.Then select or de-select the "Key figures" thats relevant for your needs Check ,generate and activate the same structure and save.
2) Create Update rules for updating this info structure by copying the rules of S115.
SPRO> Logistics general > LIS > Logistics data warehouse > Data basis >Updating > Specific definition using update Rules > Maintain update rules.
Enter the newly created Structure name and choose teh Update group 26 (use drop down) and enter the S115 and 26 as teh group and rules to copy from.
Delete the rules thats not relevant for your needs and then check, and Choose "generate: and then activate the "UPDATING" and save.
3) Activate the Update type for the new structure. SPRO> Logistics general > LIS > Logistics data warehouse > Data basis >Updating > Update Control > Activate Update.
Choose PM and double click on the new structure that you had just created and chosoe Period and Type of updating (2: Similar to other standard info structures). and save.
This should start updating New orders that you are creating from Now on.
However if you would like to pre-populate existing data in this structure for analysis, then you would have to run through the generation program in background for this specific structure.
SPRO> Logistics general > LIS > Logistics data warehouse > Data basis >tools > setup of statistical data >Application specific setup of statistical data > perform setup - PM.
Here make sure to do the PMIS statistical setup (This might be redundant, if you havent changed any value category that updates PMCO table) and Set Up: Plant Maintenance IS(Make sure to choose your specific structure).
You should be able to check the table entries to confirm that the program has updated the table (Name of the info structure).
The defaulted version could be different from the standard version (000).You could copy the data from one verion to another version using the first step in this block.
Once the genration is complete you should be ready to use this structure using MCIS transaction (PMIS > Standard analysis > User defined analysis).
This will list out all the user defined structures and you can pick and execute the one that you had just created.

Dynamic Programming Using Java

hiiii...anyone knows how to use a dynamic programming to compare a mouse movement using java??? i hope some one can help me......

This was just an idea. I do not know of any program
implementing this. I will not help you store coordinates
into a database, but I can explain my suggestion in
more detail.
Since the characters might be more dependent on the page
then the user, you must make a sub character for each page.
Your table row must then contain following fields:
user, time, page, x-cord, and y-cord.
Now assume following
- we will use the characters 'average speed' and
'centre of gravity of movement'.
- we have two sessions of data, that is two sets of table
rows as described above. Every set belongs to different
users.
- the sessions are spread on a set of pages.
Now we will compute the distance between these users. There
are a lot of distance metrics but let us choose the most
common one. Let P be a set of points in R^n and p.n
be the n coordinate of the point p in P. Then for any p1
and p2 in P, define the distance metric to be
D(p1,p2) = summa_{over n} (p1.n-p2.n)^2
Define the average speed for a certain user and page to be
Speed(user, page) (in) R. Further more let
Gravity(user, page) (in) R^2 be the centre of gravity of
movement for a user and page.
Then the total distance is
D(user_1, user_2) = summa_{over all pages} k1*D(Gravity(user_1, page), Gravity(user_2, page)) + k2*D(Speed(user_1, page), Speed(user_2, page))
where k1 and k2 are constants determines the importance
you want to assign the two characters.

Dynamic programing

Hi All,
I need your help to write the code for the below.
We have 12 add-on tables.
We need to check one by one all 12 table for the transaction data matching. Each table structure is different.The transaction data structure will also be different during runtime.
If we found the matching in any one of this table then we need to select the specific or required field from that table and put into the internal table and come otherwise continue checking the 12 add-on tables for transaction data field matching.
This should be done using the dynamic programming.
So here table name and the field selection and also the where condition all are dynamic.
Please help me on this.
Regards
Gautham.

there are too many threads on this.

I would like to do a program that have one string control and one string indicator, any character that I type in the string control in the same time it will be appear in another string (indicator). How can help me?

I would like to do a program that have one string control and one string indicator, any character that I type in the string control in the same time it will be appear in another string (indicator). How can help me?

Why not use an event
Add a While Loop, inside the loop add the Event Sructure.
Now in the event structure selecd the String Controls.value change event to
react
and the new value inside the event that you get,( connect to the String
indicator box.

Download a special kind of internal table (dynamic programming)

Hi guys,
with dynamic programming, i've created a complex internal table of this type :
KNA1                          |
KNB1                          |
GS_CUSTOMERADDRESS            |
GS_CUSTOMERGENERALDETAIL      |
The declaration of the internal table is :
TYPES: BEGIN OF gty_record,
        table TYPE tabname,
        dataref TYPE REF TO data,
       END OF gty_record.
This means that each line, has a different line-type. In the first field of the table, i have the name of the structure. In the second, the data-part (in debug double click on leads to structure contents - field by field).
The structure KNA1 contains C and packed (P) fields also so when i pass the internal table to FM GUI_DOWNLOAD, i have this short-dump : UC_OBJECTS_NOT_CONVERTIBLE.
Is there a way to solve this problem quickly?
The goals is download all data of a customer into a local file. Data is distribuited on different structures, readed by standard bapi 'BAPI_CUSTOMER_GETDETAIL2'. This file will be read in another program, of another system.
Any hints/suggestion will be appreciated.
Thanks a lot.
Andrea

Hi Sandra,
thx for you suggestions.
About your answer :
" Or use a DO. ASSIGN COMPONENT sy-index OF STRUCTURE ... to loop at each field, and do whatever you want with them (using WRITE ... TO ... for example, to convert numbers into text)."
I cannot use this approach to the problem, because i should keep in mind the dimension of single fields and the blanks should be concatenated also, but RESPECTING BLANK switch of concatenate instruction doesen't exists in 4.7 abap.
Sure, i can use a workaround, but i'll have a lot of programming.
"you could use XML for instance. It's rather standard! By using CALL TRANSFORMATION ID SOURCE dataObject RESULT XML string."
This could be the solution. I've already read some posts about it before write mine. I should test it: i don't know if in 4.7 release works. So i could transform the internal table to xml and save to text file.
But then, how i can read xml string and mapping again in this special kind of table ?
Is CALL TRANSFORMATION ID SOURCE XML String RESULT Dataobject instruction sufficient to perform this task?
Thanks a lot

Help in defining organization structure with reference to new gl

Hi Experts,
I need some help in defining organization structure with reference to new GL. I have three legal entities spread across 17 locations. In each location there may be three legal company entities in operation. And in each company code there are 5 to 6 several product lines. I have defined 3 legal entities as 3 company codes, but my concern is how do i define these 17 locations as and how do i define these product lines. We do location wise reporting meaning if i take one location i draw P&L for all the 15 product lines of the combined 3 company codes. Like wise for we do individual location wise reporting. As ususal we do budgeting location wise for departments for each individual company code.
I thought of using business area as locations, but i heard SAP doesnt support anymore on business due to new gl concept and moreover business area doesnt populate in all transactions. Can we use new gl concept like segments and so, i am sorry i am very new to New gl. Can the location wise combined reporting be done in consolidation or it can achieved in new gl
Can somebody share their expertise on how to achieve this either my new gl or traditional gl.
Thanks in advance

Implement a program by using data structure

i've learn link-list,b-tree,red black tree,hash table. now it's time for me to implement a program using any one of these. i've no idea about how to start, and what kind of program should i write? what kind of program use data structure? i want some simple example program to make me understand. can anyone help me?
thank 4 u r time,
makio

what sort of program do use data structure? let's say
i want to use binary search on data , how can i?As nasch said: pretty much any program uses data structures.
Okay, let's say you want to try binary search. You could do that on an array, on a singly linked list, on a doubly linked list, probably on others that I can't think of right now.
If you just want practice using the data structures you've learned, then why not write a binary search over several different ones? That will give you a feel for how they differ in usage and performance.
Or, you can just pick any kind of program that interests you. Unless it's trivially small and simple, there will probably be a use for one or more of the data strux you've learned.
A chat program needs data structures to hold curently connected users, ongoing conversations, maybe a queue for messages waiting to be sent.
A card game needs to be able to search to see if a given card is in a given hand. Needs to hold all the cards in a deck that has to be shuffled. Dealing is like popping off a stack.
A database of students and their courses might want to keep something in an ordered tree--by last name for instance.
What applications interest you?

Create dynamic internal table with deep structure;cell coloring dynamic ALV

Hi,
My requirement is to do cell colouring for a dynamic ALV.
So I am creating a dynamic internal table using the following method.
CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = i_fieldcatalog[]
    IMPORTING
      ep_table        = i_output.
But how do I define field COLORS which should be again an internal table ?
Is there any other way for cell colouring?
Putting my problem in another way:
How do I create a dynamic internal table with one field as another internal table.
Quick replies are highly appreciated.
Thanks,
Nisha Vengal.

halo Nisha
Before building the display table . you can add the field in the feild catalog right . This display table gets generated from the field catalog right
1 Create a global structute say ZEXTEND_FIELDCAT
2 Have fields like STYLE type lvc_t_styl
                         COLOR type LVC_T_SCOL.
3 Now you have to extend ur fieldcatalog
l_fieldcat-fieldname = COLOR'.
l_fieldcat-ref_field = 'COLOR'.
l_fieldcat-ref_table = 'ZEXTEND_FIELDCAT'.
APPEND l_fieldcat TO lt_field_catalog.
CLEAR l_fieldcat.

Dynamic Programming - RTTC - Appending lines

I give up! Maybe someone else can help me with this Dynamic Programming problem.
I am using RTTC to create an itab. Now I want to append lines and for some reason can't seem to crack the syntax I need.
My latest attempt looks like this...
            FIELD-SYMBOLS: <table> TYPE ANY TABLE,
                           <row> TYPE ANY.
            lo_sdescr      = cl_abap_structdescr=>create( lt_components ).
            lo_tdescr      = cl_abap_tabledescr=>create( lo_sdescr ).
            CREATE DATA lr_alloc->alloc_table TYPE HANDLE lo_tdescr.
            CREATE DATA lr_struct TYPE HANDLE lo_rdescr.
            ASSIGN lr_alloc->alloc_table->* TO <table>.
            APPEND INITIAL LINE TO <table> ASSIGNING <row>.
The syntax check I get on the APPEND statement is "You cannot use explicit or implicit index operations on tables with type "ANY TABLE".
All the doco and examples I can find use a simple "SELECT * ... INTO CORRESPONDING FIELDS OF TABLE <table>" syntax which it not what I need to do.
Any help it appreciated.
Thanks
