Recieve data from another program

hi, i'm trying to recieve some kind of data from another program i know where is the output of the program the problem is that i don't know how to get these datas. for example my program is writing the output in a temporary file but i'd like to recieve these datas without a temp file. the question is: Is possible to make a class that be listening to the meddle and when any program send any data to its it recieves??? if yes how can i do it?
i'm working with girds and is easy to descover where my output will arrive the only problem is how to recieve.
Thanks

Or a pipe. In unix you can create a named pipe with mkfifo, which can hadilly do this kind of transfer.

Using Java to Log Data from another program

I have a program that I want to log data from while the program is running. The program has a textarea that gets updated with data from the internet. I want to be able to read this textarea and store the data so it can be analyzed later.
I don't know what the program was written in, only that it is running on Windows.
Can Java "watch and read" another program?

i think that easyest way would be to listen for network traffic and then parse relevant information from there...
you could make a java app to act as proxy for that programm (maybe) and then log everything that goes through socket, or if you don't want to do that, then you could also use some other software that can listen network and look from there information that intrests you...
of other softwares id recommend somekind of Iris soft that i used 3-4 years ago... realy easy to use nd runs on windows as well... even better would be ngrep, but i don't know if it has any windows versions...

Using Field symbol to fetch data from another program

I have a requirement where i need to fetch value of a field from one of the function pool so i have written a sample progam to check the logic but its doest seems to work its giving dump.
Basically i want to know how to use <programname><fieldname> with fieldsymbol.
REPORT ztest1.
DATA test(25) VALUE 'ggg'.
submit ztest.
report ztest.
constants: lv_memory(25) type c value '(ZTEST1)TEST'.
field-symbols: <fs2> type char25 .
assign (lv_memory) to <fs2>.
write : <fs2>.
I am getting same field symbol assignment dump

Hi Rahul,
You can use this concept in between the FUNCTION MODULES where both are
under same FUNCTION GROUP ( as both the FM's have same global memory area ).
And also if you are calling an FM or method from your program ,you can have the data of the calling program in that called FM or METHOD.
Hope this may help you.

How to call an alv report from another program and return back

     Hello ,
I am calling one abap program (Prgm B) from another program (Prgrm A).
Here, Prgm B is an ALV report. I have fetch some data from Prgem B that gets stored in an internal table.
Now, I am using below code in Prgrm A,
SUBMIT Prgrm B VIA SELECTION-SCREEN
                      WITH SELECTION-TABLE rspar
                      EXPORTING LIST TO MEMORY
                      AND RETURN.
When Prgrm A executed, it lead me to selection screen of Prgrm B and when I click F8, it shows me the report output, In short, it doesnt return back to Prgrm A. It ends up showing me the alv report if Prgrm B even afetr using RETURN statement.
I want to get back to Prgrm A by fetching some data from Prgrm B.
Please let me know, if i am missing something.

How to edit a program dynamically called from another program

Hi all,
Can anyone help me in coding for a program which call's another
report dynamically from selection screen(for instance z_dynam_called)
and retreive the whole content of the dynamically called program(z_dynam_called)
into an internal table and replace the contents of the internal table with some new code and put it back in z_dynam_called and save it.
Thanks in advance.
Needful will be rewarded with points

Hi,
Follow this:
1) U can pass data from one program to another in a single login using SAP memory......
2) u can create a DBtable update dat table using ur first pgm and fetch from second program.....
3) U can pass the report output using EXPORT TO MEMORY addition and get it back using IMPORT FROM MEMORY..........
Eg:
Export the selected rows to the next program
EXPORT final TO MEMORY ID 'ABC'.
CALL TRANSACTION 'XXX'.
XXX is the tcode for the other program where u want to import the values.
In the second program
INITIALIZATION.
IMPORT the internal table from the first program
IMPORT final FROM MEMORY ID 'ABC'.

Best way to recieve Datas from MII in SAP

Hi everybody,
We are discussing which way is the best to get data to SAP when SAP is the initiator.
We tesed RFC but it looks like that if I call a transaction in MII as a rfc I can only send data and it is not possible to recieve data in this way. Can somebody confirm that?
To send data to MII we usually use IDOCs when SAP is the initiator.
To send data to SAP we usually use rfc when MII is the initiator.
To send data to MIIwe usually use rfc when MII is the initiator
But what can we use if we want to send data to SAP and SAP is the initiator?
Thanks for your help.
Regards,
Matthias

Hi,
thanks for your quick answer.
Is it possible to use an rfc in ABAP-Code and recieve data?
I think this is not possible.
Our Business-case:
A user starts an SAP-Programm (e.g. custom transaction) where he has some informations to a machine.
In this program we also want to see data from MII.
it should be something like this in ABAP-code:
CALL FUNCTION mii_transaction DESTINATION mii_dest
parameter_list.
But I read in a help-file that it is only possible to send information not to recieve. Is this correct?
Or is it also possible to recieve data from mii like this (in parameter_list)?

Matthias

Reading data from another database

Hi Folks!
I need to read some data from another non-sap system database to validate something in R/3. Does this is possible. If it is possible how could this be achieved?
Thanks in advance for your help.
Regards,
Gilberto Li

There are a couple of ways to do this. One, you can create an executable on the other non-sap system that you can call from SAP as a system command. So let us say you write a unix script that takes a value as input and returns a flag as output. Within the script you will check that value against this non-sap database. In SAP, you will create a system command in SM69 and then execute it in your program via function module SXPG_COMMAND_EXECUTE.
Alternatively, you can use the RFC route but you need to setup RFC connection between the two systems.
You can also bring this validation table into SAP as a one time or periodically updated table and then do the validations within SAP.

Checking whether field-symbol from another program is assigned?

Hi all
I'm attempting to access a FS from another program.
As the FS can be assigned, or unassigned within that program, how do I checked for that in my calling program?
e.g. calling program;
FIELD-SYMBOLS: <fs> TYPE STANDARD TABLE.
DATA: lv_var(40) type c.
lv_var = '(ZTGT_PROG)<read_fs>'.
ASSIGN (lv_var) TO <fs>. " statement might dump...

Hi
Go through this doc and use accordingly
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.

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

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>.

... 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.

Receive POST data from another URL and process using Struts

Hi there
We have a website and as of now we are receiving some data from another URL which is received as an appended part of the URL. My application uses Struts and we process the received data and send back a response.
Now my question is, I have been asked to change this behavior because there are more parameters now which cannot be passed through the URL. I am supposed to get the data from the other URL as POST data (as a form) and I have to create a new Struts action to receive this data, process it and send the response back to the requesting URL.
Please explain me how to do this using some example code snippets.
Thanks a lot

Lookup in XI is used to call the target data storage system and get data from there to your mapping programme.
In XI you can do Lookup in Message Mapping, Java Mapping and in XSLT Mapping. Previously Lookup in XI was system dependent. But now what ever the system are i.e. SAP system or non-sap system(Oracle,MS SQL etc) lookup API are same.
Overview of Lookup
- Lookups are used to identify/request the data from mapping program.
- It interrupt the process and looking for data which was stored in target system.
- It get that data and comeback to process and continue with that data.
Types of Lookups in XI
- JDBC Lookup: JDBC lookup is used for accessing data from database (non SAP).
- RFC Lookup: RFC lookup is used for accessing the SAP Data.
- SOAP Lookup: SOAP lookup is used for accessing data from Webservice
Steps to perform Lookup in Mapping
Import package com.sap.aii.mapping.lookup.*;
Create connection to the target Database system.
// Determine communication channel created in ID
Channel channel = null;
channel = LookupService.getChannel("DB-SYSTEM-NAME","DB-CHANNEL-NAME");
// Get system accessor for the channel.
DataBaseAccessor accessor = null;
accessor = LookupService.getDataBaseAccessor(channel);
Build the Query String.
Getting Result
// Execute Query and get the values.
DataBaseResult resultSet = null;
resultSet = accessor.execute(Query);

How to create a variant to a report from another program at run time

Hi experts,
when i am using FM : /OSP/REPORT_CREATE_VARIANT to create a report variant from a program then i am getting an error 'For object /OSP/ERPNR , number range interval 01 does not exist ', how should i avoid it or can any one help me out to create a report variant from another program at run time with the results of the program.so that i can execute the report from here with this variant

If i understand you,
- You can use a FM like [RS_CREATE_VARIANT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=rs_create_variant+&adv=false&sortby=cm_rnd_rankvalue] to create a variant and then use it in the [SUBMIT|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096d67543b11d1898e0000e8322d00/frameset.htm] statement USING SELECTION-SET.
- But you may also use SUBMIT with WITH parameters which doesnt require variant creation and with much less programming efforts.
- You can mix the two solutions also.
So what is you actual requirement, also look at some documentation like [ Scheduling a Job: Full-Control Method|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096ce5543b11d1898e0000e8322d00/frameset.htm]
