Dynamic Programming : Bind table
Hello to all,
I intend to bind a table dynamically for which i am following these steps:
1. Created the context node dynamically in WDINIT.
2. Filled the context node (made a select query and then using bind_table)
3. In WDDOModify, used the following code
CALL METHOD VIEW->GET_ROOT_ELEMENT
RECEIVING
ROOT_VIEW_ELEMENT = LR_ROOT_ELEMENT .
"DOWNCAST IT
LR_CONTAINER ?= LR_ROOT_ELEMENT.
4. Created an UI elemnt and bound the data source
CALL METHOD CL_WD_TABLE=>NEW_TABLE
EXPORTING
BIND_DATA_SOURCE = 'SFLIGHTS_CONTEXT'
ID = 'TABLE_SFLIGHT'
RECEIVING
CONTROL = LR_TABLE
5. CALL METHOD LR_CONTAINER->ADD_CHILD
EXPORTING
THE_CHILD = LR_TABLE
6 CALL METHOD CL_WD_FLOW_DATA=>NEW_FLOW_DATA
EXPORTING
ELEMENT = LR_TABLE
RECEIVING
CONTROL = LR_FLOW_DATA
With this all i am getting in the browser is an empty table. Well i have used the <b>bind_data_source</b> parameter = the context, and this context is very much filled in the WDDOINIT method but can't understand this behavior of getting an empty table.
Please help me with this
Hi Abhishek,
I am putting the Exaple code which will help you to solve the problem. Here the logic in my example are the User enters TABLENAME into the Input field and he want to display the information about that Table with data.
DATA: lr_root_info TYPE REF TO if_wd_context_node_info,
lr_node_info TYPE REF TO if_wd_context_node_info,
lr_context_node TYPE REF TO if_wd_context_node,
lr_context_elem TYPE REF TO if_wd_context_element,
lv_tabname TYPE string,
lr_db_tab TYPE REF TO data.
FIELD-SYMBOLS: <lfs_db_tab> TYPE ANY TABLE.
read db table name from context
lr_context_node = wd_context->get_child_node( name = 'TABLE_NAME' ).
lr_context_elem = lr_context_node->get_element( ).
lr_context_elem->get_attribute(
EXPORTING name = 'TABLENAME'
IMPORTING value = lv_tabname ).
TRANSLATE lv_tabname TO UPPER CASE.
get meta data info of root context node
lr_root_info = wd_context->get_node_info( ).
create context structure
CALL METHOD lr_root_info->add_new_child_node
EXPORTING
STATIC_ELEMENT_TYPE = lv_tabname
name = 'DB_TABLE'
receiving
child_node_info = lr_node_info.
create data object of correct type and assign field symbol
CREATE DATA lr_db_tab TYPE TABLE OF (lv_tabname).
ASSIGN lr_db_tab->* TO <lfs_db_tab>.
read DB content
SELECT * FROM (lv_tabname)
INTO CORRESPONDING FIELDS OF TABLE <lfs_db_tab>
UP TO 100 ROWS.
bind table to context
lr_context_node = wd_context->get_child_node( name = 'DB_TABLE' ).
CALL METHOD lr_context_node->bind_table
EXPORTING
new_items = <lfs_db_tab>.

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.
AndreaHi 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 needed regarding Dynamic Programming
Hi,
While doing dynamic programming , we bind the context variable with two types of
values .
1 . ddic
2 . extern
My doubt is in which case we should use ddic and where to use extern .
Can anybody help me out regarding this.
Thanks a lot.Hi Ki,
Predefined, Web Dynpro UI-specific, and user-defined Dictionary types all have the
prefix ddic:.
wdContext.getNodeInfo()
.addAttribute(
"Visibility",
"ddic:com.sap.ide.webdynpro.uielementdefinitions.Visbility")
Logical Dictionary types from Adaptive RFC models have the prefix extern:.

How to change the images dynamically in a table.
Hai,
How to change the images dynamically in a table based on the condition in webdynpro abap.
Edited by: Ravi.Seela on Oct 13, 2011 2:17 PMThis has been much discussed earlier. Do search posts.
For your scenario i would do the following.
inside your node which is binded to the table, i create a new node image with cardinality 1 ..1 and a attribute called path of type string.
create a supply function for the node image .
Supply method now has a Element (Parent element ) and node.
Based on your record in element, set the right image source to path attribute and bind the node.
This will make sure that the framework calls the image supply function for every row in a table. -
How to display the rows dynamically in the table display in web dynpro abap
Hi experts,
There is a visible row count tab where you can give the no of rows to be displayed in the output table, but i want it to be done dynamically as the row count of my table may change dynamically at runtime.
And i want to know how to reduce the width of a column as my table display is taking the length as per the binded table specifications.Can anyone please help me out in this issue.
Thanks in advance,
Anita.Hi Anita
You can bind the visiblerowcount property to the a context attribute. and at runtime you can set the context attribute to the no of rows you want in your table,

Dynamic context binding in web dynpro alv
I use dynamic context binding (see code below to show and edit the ALV table.
'DB_TABLE' is a tranparent table. It works fine.
But now this table should be expanded with additional fields which are only known at runtime and could be different from case to case.
How can I get these fields in the context dynamically?

Dynamic Programming - Attribute Mapping
Hi
Im working on Web Dynpro for ABAP Application where Im using dynamic programming.
I've created node and attributes dynamically (using ADD_NEW_CHILD_NODE & ADD_ATTRIBUTE methods resp.) & bound the dynamically created Textedit UI elements to those attributes. The application is running fine upto this.
Now I want to get the text entered in textedit field from the context. For this I'm using GET_ATTRIBUTE method. Here Im getting dump with error message 'Could not find attribute V_TEST.1.CN_INPUT.1.ATTR11 '. When I debug the GET_ATTRIBUTE method, I found out that the internal table DYNAMIC_ATTRIBUTES is initial. The internal table ATTRIBUTES->* is getting populated in the metod ADD_ATTRIBUTE.
Pls suggest the solution or any alternative method for this.Hi ,
this is happening because the attributes are added dynamically . to get the attribute value at runtime u have to follow the below procedure .

Dynamic Programming - RTTC - Appending lines

My latest attempt looks like this...

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.

Dynamic Programming - subsequence counting
I have two string arrays (X and Y) and I want to count the number of times that a sequence X appears as a subsequence of a sequence Y by using dynamic programing. Could you guys give me some ideas about how to create the DP table?
thanksblack_makeba wrote:
yes, this is a java programming. And the task is to figure out the algorithm. If I knew the algorithm, Coding would be trivial. So I am asking for any ideas about the algorithm.I have a weak spot for problems like this so here's a solution but I'm not sure it qualifies as "dynamic programming" in your assignment.
You start out with an X string like "abcd". We call this string X(0) because it's in its initial state. Now if the first letter "a" has been found the string is called X(1) which is "bcd" (the first letter has been found and is no longer of interest). When the X(0) string "abcd" has advanced to X(4) all letters have been found.
Example:
X(0): "abcd" - initial string
X(1): "bcd" - first letter found
X(2): "cd" - second
X(3): "d" - third
X(4): "" - whole string found
In the general case you have strings from X(0) to X(N) where N is the number of letters in the original X string.
Now you consider each letter in the Y sequence from left to right and for each letter you create an X(0) string. You may also have accumulated a number of X strings in other states like maybe five X(1) and four X(2) etcetera. You have a look at the current letter in the Y sequence and check if the X(0) string can be advanced to X(1). If not you discard it. Once a string is in X(1) it's never discarded. Then you also check all other X strings and see if you can advance them. You never advance a string beyond the X(N) state. This proceeds to the end of the Y sequence when the number of X(N) strings tells you how many hits there were.
Now here comes what I would call a "dynamic programming" strategy. In the above algoritm you keep all X strings of all states but you don't have to. You only need to know how many X strings you have in each state because they all advance too the next state in unison. So you get a table with one entry for each X state. The entry holds the number of X strings in that state.
What you need to figure out is how to update the X state table as you consider each letter in the Y sequence. The entry for X(N) is the number of hits. -
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. -
