REF TO DATA to Structure

Hi Folks!
I got a little problem with moving data.
I'm using ref to data for a general data definition. Unfortunately after I create the data using a certain type, let's say 'A', I cant move the data of the created data to a structure of type 'A'. (It can also be type 'B'; that depends on the user input; thats why I am using ref to data).
Is there a way to move the data from the cre3ated structure to the static type structure?
I'm looking forward to reading from you
Best Regards!

Hey Kamil,
You can use a field symbol to move the data like this:
data: dyn_struc type ref to data.
stat_struc type A.
field-symbols <fs> type data.
create data dyn_struc type A.
assign dyn_struc->* to <fs>.
stat_struc = <fs>.
Of course, this will only work if dyn_struc was actually created with type A. Otherwise, the last line will cause a runtime error.
Best regards,
Erik

How to define a TYPE REF TO data into my local variable/structure?

Hello,
I am trying to implementing a BADI, in its signature part,
c_accit TYPE REF TO data.
My pseudo code goes like,
DATA: l_itm_details TYPE REF TO data.
l_itm_details = c_accit.
l_itm_details-koart = 'D' =====> here am getting error!
* Do processing
ENDIF.
Here am getting error that, l_itm_details is not a structure! Pls. let me know how to fix it?
Thank you

Hello,
c_accit TYPE REF TO data.
C_ACCIT is a "data reference" parameter. In order to access its components you have to "de-reference" it!
FIELD-SYMBOLS: <l_itm_details> TYPE ANY,
<l_value> TYPE ANY.
ASSIGN c_accit->* TO <l_itm_details>."De-reference the data reference
ASSIGN COMPONENT 'KOART' OF STRUCTURE <l_itm_details> TO <l_value>.
If you know the structure of the data reference variable you can define your field-symbol <l_itm_details> of that type directly, else you can define a generic type as mentioned in the code snippet.

Hi Uwe,
Thanks for the reply.
I wrote the following code:
data: ldo_data    TYPE REF TO data,
                  LV_PARTNER TYPE STRING.
FIELD-SYMBOLS:
<ls_struct>      TYPE any,
<ld_fld>           TYPE any.
    lv_value_node->if_bol_bo_property_access~set_properties( ls_ch ).
   LV_TABNAME = LV_VALUE_NODE->GET_PROPERTY_AS_STRING( IV_ATTR_NAME = 'TABNAME' ).
   IF LV_TABNAME = 'CRMA_PARTNER'.
     Ldo_data = lv_value_node->get_property( IV_ATTR_NAME = 'TABNAME' ).
     ASSIGN ldo_data->* to <ls_struct>.
     ASSIGN COMPONENT 'PARTNER_NO' OF STRUCTURE <LS_STRUCT> TO <LD_FLD>.
     IF SY-SUBRC EQ 0.
       LV_PARTNER = <LD_FLD>.
     ENDIF.
Now when i debug:
The LDO_DATA only consists of string CRMA_PARTNER.
It does not give me the data:(
what is the possible reason?
Thanks and Regards

Processing a data mining structure throws an error

Processing a data mining structure throws an exception stating the following:
"Errors in the OLAP storage engine: An error occurred while the 'IDK' attribute of the 'Test IDK' dimension from the 'Project1' database was being processed."
"Errors in the OLAP storage engine: The attribute key was converted to an unknown member because the attribute key was not found. Attribute IDK of Dimension: Test IDK from Database: project1, Record:17072643"
I am using a DB view as a DSV. It does not have a unique primary key. Since DB view is getting multiple results per IDK, the IDK repeats for multiple rows. The same IDK is defined as Key column for the mining model. Not sure if that is the
issue. Please help!
Thanks
Shallu

Hi Shallu,
According to your description, you use a database view in the data source view that do not have a primary key, so you get the error
Errors in the OLAP storage engine: The attribute key was converted to an unknown member because the attribute key was not found. Attribute IDK of Dimension: Test IDK from Database: project1, Record:1707264
when processing the project, right?
In this case, please refer to the links below which describe the similar issue.

How to determine type and access of REF TO DATA

Hello experts,
I have a structure with two fields, one string as name/ID and the second one REF TO DATA as placeholder for any value, so DATA can take for example another string or a numeric value or whatever. Ok, now I want to handle this DATA based on it's type, which is unknown at that point. So I first DESCRIBE the field (its type). If for example this type results in a string, I want to move this string data from REF TO DATA into a local string value. Then I want to reformat the string value and save it again to the REF TO DATA field.
So, in short, I have these tasks:
1. determine type of REF TO DATA
2a. if it's a string, then move the val. of the string into a local string variable
2b. or alternatively do something else, if it's not a string value
3. do something with the local string, then save it back to the REF TO DATA field
Any ideas?
Thank in advance for your help!
Kind regards, Matthias

Hi Matthias
I think you missed a little and very important detail here:
ASSIGN ls_rec-value TO <fs>.
That's not what we want, instead you need to use:
ASSIGN ls_rec-value->* TO <fs>.
That's why you are obtaining this type 'l' which is refering to a TYPE REF TO DATA itself. Doing it the right way your final type would be 'C' which corresponds with a character data type.
Best Regards

Add line to type ref to data field - type table

HI All,
I have field that is defined as type ref to data ,and the type of it is table with data inside of it lr_data.
I have the also the table type of lr_data and I want to add additional line to the type ref to data field.
How can i do that ?
For example
TYPES: BEGIN OF bank_list,
         country_key type string,
         bank_key    type string ,
         bank_name   type string,
         bank_city type string    ,
       END OF bank_list.
data lt_bank type table of bank_list.
data lr_data data ref to data.
Now lr_datae is type lt_bank " in _Runtine
and contain 4 entries .
I get the lr_data with 4 entries and I want to add new entry to the table.
How can I do that?
Thanks,
Joy

Data: stru_tab type ref to data? what data refers to?

Dear friends,
                     Relatively iam new to WDA. can u please explain me below statement.
data: stru_tab type ref to data.

Actually there are not really any Web Dynpro sepecific data types. The ones mentioned are simply data dictionary data types that are defined for use with WD, but can be used in any ABAP applications. You should start your research with just ABAP data types. Look in the ABAPDOCU transaction or search the keyword documentation for DATA. There is lots of documentation on the ABAP native data types.
Here is a little bit of it:
Predefined ABAP Types
The table below shows the predefined ABAP types. Additional attributes can be found under value ranges and initial values.
Type Length Standard length Description
b 1 Byte   1 byte integer (internal)
c 1 to 65,535 characters 1 character Text field
cursor as i as i Database cursor
d 8 characters   Date field
f 8 bytes   Floating point number
i 4 bytes   4 byte integer
n 1 to 65,535 characters 1 character Numeric text
p 1 to 16 bytes 8 bytes Packed number
string variable   Text string
s 2 bytes   2 byte integer (internal)
t 6 characters   Time field
x 1 to 65,535 bytes 1 byte Byte field
xstring variable   Byte string
These types are predefined in every ABAP program.
All predefined ABAP types in this table are elementary.
Apart from the types b and s, the predefined ABAP types can also be used to define your own data types and data objects and for typing. The types b and s cannot be specified directly in ABAP statements. Self-defined data types and data objects in ABAP programs are of the data type b and s if they are defined with reference to data elements to the ABAP Dictionary which are of the external data types INT1 or INT2.
The predefined data types string and xstring describe data objects of variable length (dynamic data objects). While the length of data objects in all other elementary data types is determined for its whole lifetime, the length of text and byte strings varies according to their content (the maximum size of a string is determined by profile parameter ztta/max_memreq_MB, see Maximum size of dynamic data objects).
The program-globally predefined data type cursor is currently synonymous with the predefined ABAP type i. This is required for the declaration of a cursor variable for database cursor handling.
All predefined ABAP types for which a length interval is specified in second column in the table are generic, which means that the length is not part of the type description. For the type p, the fractional portion is indefinite as well as the length.
The entries in the standard length column specify the length that is used for the corresponding generic data type when declaring data objects, if no explicit length is specified in the relevant statement.
In Unicode systems, the length must either be specified in characters and bytes. In non-Unicode systems, the length of a character is one byte, but in Unicode systems the length of a character depends on which Unicode character representation is used.
Generic ABAP Types
The following table shows the predefined generic ABAP types. A generic data type is an incomplete type specification that includes several complete type specifications. The generic types can be used for the typing of field symbols and formal parameters. The only generic type that can be used for typing of data references is the predefined type data. The predefined generic type for object references is object. When a data object is assigned to generically typed field symbols using the statement ASSIGN, or to a formal parameter in procedure calls, the system checks whether its concrete data type is a of the generic type, or is compatible with it.
Type Description
any Any data type (suitable for any type)
any table Internal table of any table type
c Text field of generic length
clike Character-type (c, d, n, t, string and character-type flat structures); in non- Unicode programs also x, xstring and any flat structures
csequence Text-type (c, string)
data Any data type
hashed table Hashed table
index table Index table
n numeric text of generic length
numeric Numeric (b, i, p, f, s)
object Any object type (root class of the inheritance hierarchy)
p Packed number of generic length and generic number of decimal places
simple Elementary data type including structured types with exclusively character-type flat components
sorted table Sorted table
Standard table Standard table
table Standard table
x Byte field of generic length
xsequence byte-type (x, xstring)
The genric types clike, csequence, numeric,simple, and xsequence are available as of release 6.10.
Notes
The generic type any currently has the same effect in typing as the generic type data. When declaring references, any cannot yest be specified after REF TO. Generic data references (REF TO data) or generic object references (REF TO object) are possible. The generic type object can currently only be specified after REF TO.
Except for the built-in generic types illustrated in the table above, there are at the moment no self-defined generic types in ABAP with only one exception: A table type defined with TYPES - TABLE OF or defined in the ABAP Dictionary without completely specifying the table key, is also generic.
Predefined Types in the ABAP Dictionary
The following table lists the predefined types in the ABAP Dictionary. These types cannot be used directly in ABAP programs, and are therefore known as external data types. Instead, they are used in the ABAP Dictionary for the definition of data types to which ABAP programs can refer. The predefined data types of the ABAP Dictionary must also be taken into account in Open SQL statements and when working with screens: Open SQL statements work with database tables defined in the ABAP Dictionary whose colums have external data types. Screen fields are also declared in the Screen Painter with reference to external data types.
Type Permitted Places m Meaning ABAP Type
ACCP 6 Accounting period n(6)
CHAR 1-255 Character string c(m)
CLNT 3 Client c(3)
CUKY 5 Currency key c(5)
CURR 1-31 Currency field p((m+1)/2)
DATS 8 Date d
DEC 1-31 Calculation/amount field p((m+1)/2)
FLTP 16 Floating point number f(8)
INT1 3 1 byte integer b
INT2 5 2 byte integer s
INT4 10 4 byte integer i
LANG 1 Language c(1)
LCHR 256-... Long character string c(m)
LRAW 256-... Long byte string x(m)
NUMC 1-255 numerischer Text n(m)
PREC 2 Accuracy of a quantity field s
QUAN 1-31 Quantity field p((m+1)/2)
RAW 1-255 Byte sequence x(m)
RAWSTRING 256-... Byte sequence xstring
SSTRING 1-255 Character string string
STRING 256-... Character string string
TIMS 6 Time t
UNIT 2-3 Unit key c(m)
For types LCHR and LRAW, the maximum number of places in a transparent database table is the value of the preceding INT2 field.
The types RAWSTRING and STRING have a variable length. A maximum length for these types can be specified, but has no upper limit.
The type SSTRING is available as of release 6.10 and it has a variable length. Its maximum length must be specified and is limited to 255. The advantage of this type compared with CHAR, is that it is assigned to the ABAP type string.
The table below shows the data types of the ABAP Dictionary that are based on the predefined types in the above table, and that can be addressed in an ABAP program. The elementary components of these data types are converted to predefined ABAP data types according to the final column in the above table, whereby the number of places m of each type is converted to lengths.
Data types in the ABAP Dictionary Data types in ABAP
Data element Elementary data type, Reference type
Structure, Database table, View Structured data type
Table type Table type
Note
As of release 6.20, a component of structures or database tables that has the type LANG can be identified as a text language. The text language is used for the conversion of character-type components of the structure when importing data from data clusters and for RFC between MDMP systems and Unicode systems.

How to retreive data from structure MDEZ in T.code CO09

As per our requirement 2 new columns are needed in a customize report .i.e
- u201Cinc. lot dateu201D
- u201Cavailable inc. lotu201D
u201Cinc. lot dateu201D:to get the values for inc.lot.date
From second screen of CO09(program: SAPLATP4 and screen number: 400) pick first date where MRP element is u201CPOitemu201D, u201CShpgNtu201D or u201CPrdOrdu201D.
u201Cavailable inc. lotu201D: to get the values for available inc.lot
Pick u201CCum. ATP QTyu201D from the same row.
These data are stored in structure MDEZ. Actually I want dat00 and MNG04 based on field DELB0. If DELB0 filed is POitem or Prdord or ShpgNt then only I should retrieve the dat00 and MNG04. IF there are more than one POitem in MRP element then we should pick the first POitems' mrp date and *** ATP qty .Can you please help me out how to get these data from the structure MDEZ.
input parameters to get the values are material number and plant.

Hi,
First of all data is never stored in structure so there is no way you can retrive data from structure.
you are looking into the screen field and it is not mandatory that it will always point to a table.
Now the qestion remains how to get the data ? you need to find database table for that field there are many ways like SE84 or SE11 where used etc.
Try to find the table if you still have the problem feel free to get back.

DATA from structure

hi firends,
i need to retreive data from table and structure is it possible
eg-- AAA is table having atr no
      BBB is strucrure in run time its having some data related to AAA table atrno
i want a select query for this plz some one provide me with example code
but i know structure will not store value.my requirement is for IDOC so structure carries data so ineed to track that
pointe will be rewarded
thanks in advance
raj

Hi Raj ,
basically addition or deletion of segments the data holds in the data record structure.
all the data pertaining to the idoc is stored and processed
in the structures
EDIDC--> Control Records.
EDIDD --> Data srecords.
goto se37 and enter the FM name
f7
u 'll see
TABLES
*"      IDOC_CONTRL STRUCTURE EDIDC
*"      IDOC_DATA     STRUCTURE EDIDD
now if i want to know the data this is is structure EDIDD now in itab
IDOC_DATA.
BREAK-POINT.
LOOP AT IDOC_DATA.
ITAB-F1 = ID0C_DATA-F1.
ITAB-F2 = ID0C_DATA-F2.
ITAB-F3 = ID0C_DATA-F3.
APPEND ITAB.
CLEAR ITAB.
ENDLOOP.
this way u can fetch the data .

VIjay

LBBIL_INVOICE. Billing Data: Transfer Structure to Smart Forms

Hi...
Can u please help me out in my query regading how the data passes to
LBBIL_INVOICE. Billing Data: Transfer Structure to Smart Forms.
I have an smartform which runs through VF01/VF02/ VF03 while pressing the print preview button.
But if i try to run it directly from driver program, no data wil be displayed. Now i have the requirement to detach from VF03.. and make it to run directly from my driver program.
what shall i have to do to achieve this. Should i have to take all the internal tables saparately or else can i use LBBIL_invoice structure itself.
If i can use that structure itself, how to make the data flow into it. Pls help me.
In my codeing these includes were there. is there anything related , is the data passes because of these includes
INCLUDE rlb_invoice_data_declare.
definition of forms
INCLUDE rlb_invoice_form01.
INCLUDE rlb_print_forms.
Pls clarify my dobut...
Thanks in advance,
Hema

1. These are normal structure
2. you can use anywhere but they designed for forms currently.
3. Yes ,it works like it will look at NAST Table -> nast table will connect the TNAPR Table -> tnapr will have smart form print program.
so smart form program calls smartform and it will show output
4. you can create your own structure and use them into anywhere like report program or forms..
5. you can see example simple form name SF_EXAMPLE_01 ,program name is SF_EXAMPLE_01 ,you can design your own form and print program.
Thanks

What is difference between data base structure and stucure in program

what is difference between data base structure and stucure declared in program level . can explain cleary if knows

Hi,
Data base structure is global decalaration you can reffer this structure in any of your developments, when ever you cahange this structure the changes automatically will get updated in all the programs.
coming to structures in program it is local to your program only, if you want to change the structure again you have to open the program and do the necessary changes.
Reward if useful.

How to find all the Master data extract structures and Extractors

I intend to create Master data dimensions closely similar to SAP BI in a 3rd party system. I would like to use SAP's standard extractors for populating the master data structures in SAP BI and then use a proprietary technology to create similar structures in a 3rd party database.
Question: How to get a complete list of all Master data extract structures and corresponding extractors?
Example: In ECC if I do SE80 and give 'Package' and 'MDX' and then press the 'display' spectacles, I get a list of structures and views under "dictionary objects" covering Material, Customer, Vendor, Plant Texts and attributes.
How do I get the remainder of the Master data extract structures viz. Purchase Info Records, Address, Org Unit etc?
Regards
Sasanka

Hi,
try the table ROOSOURCE and search the data source with string in astrick attr for master data and for text with text
This will give you the list of all the master data source in the system and it contains a column which tells about the extract structure and function module used by each.
Thanks

Using XFA javascript to refer to Data Connection data

Is it possible to use XFA Javascript to refer to Data Connection data, without referring first to a field which is bound to a Data Connection.
The aim of this is to track changes of certain fields by comparing a fields "newText" to the Data Connection's field.
Also, is it possible to have Acrobat save data back to the data connection (ie. change the data connection data to reflect changes in the current form)

Additionally, does anyone know of any documentation (preferably free) detailing the use of XFA Javascript in LiveCycle.

How to get data from structures ??

HI
I have to do a report.I had given structures instead of display tables.we cant get data from the structures. are there any FM to diaplay data from structures or shd i need to sreach the fileds in display table
Regards
Rasheed

Hi,
There are several ways to find the tables:
