How to use RFC in OO programming?

experts,
    As far as i know, we can call a function using RFC, such as:
     CALL FUNCTION 'HRRCF_MDL_CAND_OVIEW_RETRIEVE'
   DESTINATION lv_dest
   EXPORTING
     cand_hrobject         = stru_hrobject
     https                 = lv_https
   IMPORTING
     cand_overview         = ls_dataoverview
     messages              = lt_messages
   EXCEPTIONS
     system_failure        = 1 "MESSAGE lv_message
     communication_failure = 2. "MESSAGE lv_message.
Is there any way to call a OO（Object Oriented） method using RFC? I have studied the grammar of CALL METHOD, but i can't find some parameters to assign the destination.
Pls guide me. Thanks.
qiuguo

No, you have to use a function module as RFC. But you can create a custom RFC in the target system with the same input parameters as your method and call the method inside the RFC.
That should do it.

How to use upload condition record program RV14BTCI

Hi
how to use upload condition record program RV14BTCI.
kathir.

Hi,
To run this program we have to maintain Upload file in Application Directory,
We have to maintain 3 levels of records in that file.. my feel you upload through BDC or LSMW.
For your information,
The batch input program RV14BTCI reads the parameters is necessary
Giving sequential file and creates (depending on the data
In the file seq) one or more batch input sessions.
The data are seq file in the following structure expected:
- The session a session intent (Table KOBTCI, Record 0)
All other records until the next session, the intent
Last session assigned to read
- The head condition Sentence (Table KOBTCI, record 1)
All other records until the next condition,
Last read head appropriate rate
This includes the corresponding condition
Condition table
- The key sentence of a Main (Table KOBTCI, record 2)
It must be directly on the head set to follow
It contains the key condition of the table
+ Detail fields
- The season record has a subordinate clause (Table KOBTCI, record 3)
The teams relate to the key sentence in the main

How to use Enhancement spot in program

Hi gurus,
now i am working ecc 6.0, so how to use Enhancement spot in program, can anybody explain step by step.
Rewarded with points.
Thanks
Naveen

Hi Naveen ,
Enhancement Spot are available.
Examples:
-End of Executable Program, Include, Function group, Dialog module
-Begin/End of Form routine / Function module / Method
-End of a structure
-End of Private/Protected/Public Section of a local class
If you want to create Implementation , You have to right click on yellow color line and gve Zxxx and save it in any
transport request under any dev class. Then you can write your own code and save it and activate it .
Later If you want to Transport it you need to transport this request.

How to use ComponentWork CWSerial to program such thing like HyperTerminal does to communicate 2 PCs through its RS232?

Right now I use null modem cable, I can communicate 2 PCs use hyper-terminal. I wonder how to use ComponentWork CWSerial to program such kind of job? Thanks!

Hi Kevin,
Of course this will take a little work, but CWSerial should be able to handle this without too much hassle. Take a look at the example program usually included in C:\Program Files\National Instruments\MeasurementStudio\VB\Samples\Instr\Basic Serial
You should be able to use this example as a starting point.
Hope this helps out!!!

How to use RFC Function?

hey,experts
I found a RFC function in server A, I want to use this RFC function in server B.
how to use it in server B?
thanks,
kim-heum

Hi,
In system B ,
1)GOTO SM59 tcode.
Then select ABAP CONNECTIONS or R/3 Connections and click on New Connection.
2) Now give the RFC connection name and description. Then in target system give the IP address or hostname and system number and save.
3)Click on logon& security tab and give the language, client , username and password and save.
4) Now click on CONNECTIN TEST button
5) Now it will show the bytes transferred after establishing the connection.
6) go back and click on REMOTE LOGON button.
7) then it will take to other system sap easy access screen if credentials are satisfied.
8) Now go to se38 and create a program
while remote Function module you have to specify the RFC destination name.
eg
call function 'ZRFC_ADDITION'
destination 'ZRFC_CONNECTION'
here ZFRC_ADDITION is Remote Function Module and ZRFC_CONNECTION is RFC to system A.
then it works.

Thanks and regards.

How to use RFC in 7.10?

Hi,
I'm a little bit confused by the help on NW 7.10 SP7. I normally use RFC connections from web Dynpro but this time I have to use RFC from an EJB. As before I tried "SAP Enterprise Connector" which seems to be depricated.
I followed the example how to use Destination Service. It imports "cam.sap.mw.jco.JCO". After correcting one error in the given source (could never run that way), I get the JCO marked as deprecated as well. So this source code there seems to be a left over from NW 2004?
Is the destination service itself also depricated?
So I found out JCO is now depricated and I should use SAP Java Resource Adapter instead. Can I combine it with destination service or is there something similar as in web dynpro? For Ehp 1 I found this adaptive RFC package, but seems not to be available in 7.10?
What I clearly want to avoid is to give any user, password or system parameters in the source code as I'm used from Web Dynpro. Can I use the web dynpro mechanism maybe somehow?
Maybe someone can bring some light in all this
Thx,
Frank

Hi Frank
>After correcting one error in the given source (could never run that way), I get the JCO marked as deprecated as well. So this source code there seems to be a left over from NW 2004?
Not exactly. The deprecation means that the JCo API version is 2.X while JCo 3.0 is already available. However, this does not mean that you cannot use the "com.sap.mw.jco.JCO". I know lots of projects running even on 7.11 and 7.20 that still use the JCo 2.X.
>Is the destination service itself also depricated?
No, no, no.
>So I found out JCO is now depricated and I should use SAP Java Resource Adapter instead. Can I combine it with destination service or is there something similar as in web dynpro? For Ehp 1 I found this adaptive RFC package, but seems not to be available in 7.10?
Java Resource Adapter is just a new JEE container for JCo API. Still it's also has some problems. So I'd not recommend you to use it.
>What I clearly want to avoid is to give any user, password or system parameters in the source code as I'm used from Web Dynpro. Can I use the web dynpro mechanism maybe somehow?
Use JCo 2.X + Destination Service. Ignore the API deprecation.

                                       Ranges
A selection table is linked to the column of a database table, or to an internal field in the program. A selection table is an internal table object of the standard table type that has a standard key and a header line.
In addition to selection tables that we create using SELECT-OPTIONS, we can use the RANGES statement to create internal tables that have the structure of selection tables. You can use these tables with certain restrictions the same way you use actual selection tables.
A ranges table type is a special case of a table type. A ranges table type describes the structure of an internal table for administrating complex areas, i.e. the type of an internal table ranges table in the ABAP program.
The row type of a ranges table type has a fixed structure. The row type consists of 4 components SIGN (sign), OPTION (comparison operator), LOW (lower limit) and HIGH (upper limit) in this order.
1.     SIGN The database type of SIGN is C with length 1. The contents of SIGN determine for each row whether the result of the row condition is to be included in or excluded from the resulting set of all rows. Possible values are I (inclusion criterion operators are not inverted) and E (exclusion criterion operators are inverted).
2.      OPTION The database type OPTION is C with length 2. It contains the selection operator. The following operators are available:-
-     If HIGH is empty, we can use EQ, NE, GT, LE, LT, CP, and NP.
-     CP and NP are only allowed if wildcards (*' or '+) are used in the input fields.
-     If wildcards are entered on the selection screen, the system automatically uses the operator CP. The escape character is defined as #.
-      If HIGH is filled, you can use BT (Between) and NB (Not Between). We cannot use wildcard characters.
3.     LOW - The data type of LOW is the same as the column type of the              database table, to which the selection criterion is linked.
If HIGH is empty, the contents of LOW define a single field comparison. In combination with the operator in OPTION, it specifies a condition for the database selection.
     If HIGH is filled, the contents of LOW and HIGH specify the upper and lower limits for a range. In combination with the operator in OPTION, the range specifies a condition for the database selection.
4.     HIGH - The data type of HIGH is the same as the column type of the database table, to which the selection criterion is linked. The contents of HIGH specify the upper limit for a range selection.
If the selection table contains more than one row, the system applies the following rules when creating the complete selection criterion:
1.     Form the union of sets defined on the rows that have SIGN field equal to I (inclusion).
2.     Subtract the union of sets defined on the rows that have SIGN field equal to E (exclusion).
3.     If the selection table consists only of rows in which the SIGN field equals E, the system selects all data outside the set specified in the rows.
RANGES tables
We can use the following variants of the TYPES and DATA statements to create internal tables of the same type as selection tables.
TYPES|DATA .
An elementary associated type defines the type of components LOW and HIGH. It can be defined by specifying a data element or by directly defining the data type, number of places and if necessary the number of decimal places.
A ranges table type always has Standard table access mode and a standard key that is non-unique.
I think this will help u .

How to use RSAN_PROCESS_EXECUTE in abap program

Hi all,
Does someone know how to use RSAN_PROCESS_EXECUTE in a abap program to execute an analytical process created in the transaction RSANWB?
I create a variant 'ZPC_ALIM_DL' for RSAN_PROCESS_EXECUTE. I would like to execute this program with this variant in a background job, but it seems that the job executed but it does nothing.
See below a part of the code.
SUBMIT RSAN_PROCESS_EXECUTE
             WITH VARIANT = 'ZPC_ALIM_DL'
             USER SY-UNAME VIA JOB L_JOBNM1 NUMBER L_JOBCOUNT1
             AND RETURN.
Thanks in advance,
L.

Hi Ludovic,
          I am using RSAN_PROCESS_EXECUTE with a variant in process chain. simply include 'abap program' type in process chain mention RSAN_PROCESS_EXECUTE as the program name and mention the variant you created for your apd process and run. I have tested it in dev and it has worked for me. let me know if this helps!
Thanks

How to use field symbols in program

how to use field symbols can any one explain with example please..
Regards,
venki...

Hi
Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

Syntax Diagram
FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Extras:
1. ... TYPE type
2. ... TYPE REF TO cif
3. ... TYPE REF TO DATA
4. ... TYPE LINE OF type
5. ... LIKE s
6. ... LIKE LINE OF s
7. ... TYPE tabkind
8. ... STRUCTURE s DEFAULT wa
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Untyped Field Symbols ad Cannot Use Field Symbols as Components of Classes.
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN. All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT> TYPE ANY.
DATA SFLIGHT_WA TYPE SFLIGHT.
ASSIGN SFLIGHT_WA-PLANETYPE TO <PT>.
WRITE <PT>.
Addition 1
... TYPE type
Addition 2
... TYPE REF TO cif
Addition 3
... TYPE REF TO DATA
Addition 4
... TYPE LINE OF type
Addition 5
... LIKE s
Addition 6
... LIKE LINE OF s
Addition 7
... TYPE tabkind
Effect
You can define the type of the field symbol using additions 2 to 7 (just as you can for FORM parameters (compare Defining the Type of Subroutine Parameters). When you use the ASSIGN statement, the system carries out the same type checks as for USING parameters of FORMs.
This addition is not allowed in an ABAP Objects context. See Cannot Use Obsolete Casting for FIELD SYMBOLS.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See Defining Types Using STRUCTURE.
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP Dictionary (s). All fields of the structure can be addressed by name: <fs>-fieldname. The structured field symbol points initially to the work area wa specified after DEFAULT.
The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.

How to use one forms fields, program units in another form.

The whole proceessing and update is happening in one main form.
Main form has all the fields and a reprocess button which re-creates records if they have error. Record name is the primary key.
I have another small form, which just shows the list of record names in the system. I want a reprocess button next to each record name so that user will be able to just select any record name and press reprocess button to recreate any record data.
There are a lot of fields in main form and program units , which are used by the reprocess button.
Any suggestions like how to go for it?

You can either pass all the relevant data from the Small Form to the Larger form and make it reprocess the data or you can move the Program Units to a PL/SQL Library (.pll) and attach the library to your smaller form where you can call the program units. Either option requires changes to the Larger form to enable it to process a record passed to the form as a parameter or to externalize the Forms Program Units to a library.
Personaly, I would recommend you move the Program Units to a Library. This would enable you to use the processes in any form (that has the library attached).
Hope this helps,

The program is start and accept call from other program. But from time to time, I need to issue some command by pressing the keyboard, let say, ESC is closed the program, F1 is showing the stated. F2.... (This is all need to run in the command prompt windows)
My problem is this program does not have any gui interface, so how can it be added?
i do it this way
public void key(){
addKeyListener(this);
But it have compile error.
mainServerImpl.java:87: cannot resolve symbol
symbol : method addKeyListener (mainServerImpl)
location: class mainServerImpl
addKeyListener(this);
I did implement KeyListener. But just don't know how to solve this error.
can anyone tell me how to solve it or point me a source that can help.
Thank in advance!

Write your own Thread, to do this:
public class KeyThread extends Thread {
   public void run {
      while(true) {
         int i = System.in.read();
         if(i == 123) {
            break; // to stop the thread
// in your main:
Thread keyThread = new KeyThread();
keyThread.start(); // calls run() of the thread
