How to create an output file name dinamically

Hello Experts,
I have created a report which is pulling information from our databases then running it on demand in order to get a plained-text file (shedule function). My question is how to handle the file name? can i use a kind of variable to reach the required name?. For your information i was using the placeholders but i sitll need to put something else in the name which is dinamic.
I.E : Prod 2011-04-01-08-01-13.txt
2011-04-01-08-01-13 = which is the DateTime stamp
Prod = I want to change this part with a parameter which will bring the required name
I'm using Crystal Reports XI
Thanks in advance,
Agustin Munoz

Need more info, are you using Enterprise?
Nothing in Cr that can do this. If you are writing and app then typically one would use a GUID ID or some sort of time stamp, be careful though with time stamps, you could end up with a few outputs if they are generated in the same minute of second...
Thnak you

How to get the Output File Name as One of the Field Value From Payload

Hi All,
I want to get the Output file name as one of the Field value from payload.
Example:
Source XML
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_TEST xmlns:ns0="http://sample.com">
- <Header>
<NAME>Bopanna</NAME>
</Header>
</ns0:MT_TEST>
I want to get the Output file name as " Bopanna.xml"
Please suggest me on this.
Regards
Bopanna

Hi,
There are couple of links already available for this. Just for info see the below details,
The Output file name could be used from the field value of payload. For this you need to use the UDF DynamicFile name with below code,
// Description: Function to create dynamic Filename
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File" , "FileName");
conf.put(key,a);
return "";
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File" , "FileName");
conf.put(key,a);
return "";
With this udf map it with the MessageType as
(File Name field from Payload) > DynamicFileConfiguration>MTReceiver
Thanks

How to create multiple output files using TrAX?

I am new in this field. I'm trying to create multiple xml output files using TrAX. I have to parse a xml source file and output it to multiple xml files. My problem is that it only creates one output file and puts all the parsed data there. When i use saxon and run xsl and xml files, it works fine and creates multiple files...it has something to do with my java code...Any help is greatly appreciated.

Saxon has specific extensions. In this case it is <xsl:document>. That looks like a standard XSLT element, but it actually isn't. The history behind it is this: There was a proposal to create a new version of XSLT, called XSLT 1.1. One of the new features of this version was to be this xsl:document element. The author of the Saxon product, Michael Kay, is one of the people on the W3C committee directing the evolution of XSLT, so he upgraded his product to implement XSLT 1.1. But then the committee decided to drop XSLT 1.1 as a recommendation. So that left Saxon in the strange position of implementing a non-existent extension to XSLT.
The other outcome of this process was that XSLT (1.0) does not have a way of producing more than one output file from an input file. And so the short answer to your question is "Trax can't do that." However, XSLT 2.0 will be able to do that, although it is not yet a formal W3C recommendation, and when it does become one it will take a while before there are good implementations of it. (I predict that Saxon will be the first good implementation.)
One of the problems with XML and XSLT is that what you knew a year ago is probably obsolete now, because of all the evolution going on. So being new in the field is not a disadvantage, unless you get stung by reading obsolete tutorials or magazine articles.

How to create a unique file name within a main()?

I am creating a file using a button inside the main() .
Each time the button is clicked, new file should be created.
The file names should be distinct and differ in a number that follows the name for ex. MyFile1.txt, MyFile2.txt, MyFile3.txt and so on.
Any ideas?
thanks

I think you want that last line to readwhile (f.exists()) // note the absent "!"since your loop as coded will end up with a filename that does exist rather than one that does not exist. You might also tryint counter=0;
File f=null;
do
f=new File("myfile" + counter++);
while (!f.createNewFile()) // This will only create a file if it doesn't already exist.
Caution! You can't use the counter after you create the file because the counter will already be the next number. You can use f.getName(), or if you have a psychological need to use the counter, prefix the "++" and start with -1 (or just skip 0)

How to create the logical file name

Hi All,
    I have requirement where i need to post the Inventory Management data. for this i need to execute std. program RM07MMBL which is having logical file name in the selection screen. but i have placed my input file in application server.
   Can any one tell how to create the Logical filename which refers the physical path. I also tried <b>t-code SF01 & Table - FILENAMEC</b>I and found that we need to add an entry in this table but i really dont know how we have to do since this table cannot be maintained in SM30 also..
Help Me.
Thanks in Advance!...
Regards,
Ramkumar

Hi Ram,
Try using FILE transaction code...
Follow these steps to create:::
Double click on Logical file Path Definition
Click on New Entries,
Give Logical file Path name as Z_LOGICAL PATH and save it
now choose this path and double click on Assignemt of Physical path to Logical path
double click on the OS name
Give some description and give some Physical path name from AL11 transaction and save it
Now Double click on Logical File Name Definition,
Click on New Entries,
Give some logical file name: Z_LOGICAL_FILENAME
Physical file: test
Data Format: BIN
Logical Path: Z_LOGICAL PATH
Hope this helps
Regards,
Phani

How to create a unique file name each time the form is saved?

I've got a form with several data items. When the user saves the form, it saves it as an .xml file. So far so good. But then I want the user to be able to start over and put in a new data set. I used the reset form button and this clears out the old data. But when the user goes to save the form for the second set of data, the default name of the .xml file is the same as the last record set. How do I get LCD to create a unique data name each time the form is saved? I know that the user can enter a new name, but I do not want them to have to think that much.
Alternatively, is there a way that a user can enter several forms of data and save all of the data in one XML file that my PDF can scroll through or that I can import into excel and keep all of the data sets separate?

Thanks Paul for the post. It sounds like this program is simply not designed for one user to keypunch a batch of forms. It would appear to limit the program's use to users who only need to key in one record/form. While a good solution for multiple users who need to enter just one set of data, the limitation would explain why this program is not widely used.

FU FILE_GET_NAME
Text
Assign the Physical File Name Using a Logical File Name
Functionality
R/3 applications run on various platforms with various file systems. This function module enables you to use platform-independent logical file names in your application programs.
Based on definitions maintained in customizing tables for platform-independent file names, the function module converts a logical file name to the corresponding physical file name and path for the hardware platform concerned.
For this conversion to work for different platforms, the definition of a logical file name must include a logical file path, which in turn is converted to different physical file paths, depending on the particular platform. The platform-specific file name returned by the function module is composed of the physical file path for the current platform and the physical file name associated with the logical file name. Placeholders in physical file and path names are substituted at runtime by the corresponding current values.
Example
logical file name: MONTHLY_SALES_FILE
physical file name: VALUES<PARAM_1>
logical path: SALES_DATA_PATH
physical path (UNIX): /usr/<SYSID>/<FILENAME>
physical path (Windows): C:\SALES\<FILENAME>
Example 1
Get file name for UNIX platform
(current system: K11)
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
LOGICAL_FILENAME = 'MONTHLY_SALES_FILE'
IMPORTING
FILE_NAME = FILE
FILE_FORMAT = FORMAT.
Result:
FILE = /usr/K11/VALUES
FORMAT = WK1
Example 2
Get file name for UNIX platform, passing a parameter
(current system: K11)
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
LOGICAL_FILENAME = 'MONTHLY_SALES_FILE'
PARAMETER_1 = '_TST'
IMPORTING
FILE_NAME = FILE
FILE_FORMAT = FORMAT.
Result:
FILE = /usr/K11/VALUES_TST
FORMAT = WK1
Example 3
Get file name for WINDOWS platform, with file name extension
CALL FUNCTION 'FILE_GET_NAME'
EXPORTING
LOGICAL_FILENAME = 'MONTHLY_SALES_FILE'
WITH_FILE_EXTENSION = 'X'
IMPORTING
FILE_NAME = FILE
FILE_FORMAT = FORMAT.
Result:
FILE = C:\SALES\VALUES.WK1
FORMAT = WK1
Notes
All definitions needed for the platform-independent assignment of file names are maintained client-independently with transaction FILE. Logical file names (but not logical file paths) can also be defined specifically for the current client with transaction SF01. Transaction SF07 generates a list of current definitions.
The following concepts are used in the platform-independent assignment of file names:
Logical file name
A descriptive name for a file which is associated with these values:
physical file name
file format
logical file path.
If no logical file path is specified, the function module returns the physical file name only; placeholders are substituted by current values.
Physical file name
The physical file name may contain placeholders.
Logical file path
A descriptive name for a path which is associated with these values:
syntax groups (groups of operating systems)
physical file paths.
Physical file path
The physical file path is defined for a particular syntax group. It must contain the reserved word <FILENAME> as a placeholder for the file name. It may also contain other placeholders.
Operating system
Presentation server and application server can run under different operating systems. The current value for the application server can be obtained from the system field SY-OPSYS, the value for the presentation server by calling function module WS_QUERY.
Both operating systems must be defined and assigned to a syntax group.
Syntax group
Group of operating systems with a common syntax for file and path names (e.g. HP-UX and SINIX).
Placeholder
Reserved words, set in angle brackets, which can be included in physical file and path names (e.g. <DATE>, <FILENAME>). You can find information on possible reserved words in the online help (F1 help) for the fields physical file name and physical file path when maintaining platform-independent file names with transaction FILE.
If the logical path associated with a logical file name does not specify a physical path for the current operating system (syntax group), the path stored in the profile parameter DIR_GLOBAL of the current system is used for generating a complete platform-specific file name.
Parameters
CLIENT
LOGICAL_FILENAME
OPERATING_SYSTEM
PARAMETER_1
PARAMETER_2
PARAMETER_3
USE_PRESENTATION_SERVER
WITH_FILE_EXTENSION
USE_BUFFER
ELEMINATE_BLANKS
EMERGENCY_FLAG
FILE_FORMAT
FILE_NAME
Exceptions
FILE_NOT_FOUND
Function Group
SFIL

How to automate multiple output file names from a single input image?

I have about 100 eps cmyk 4000 pixel wide images to process daily. The website needs several jpeg editions of the same image: 1000 pixel wide, 850 pixel wide, and 80 pixel wide.
Question:
Can I load the single source and save three differently named outputs through a single droplet?
I was hoping for an Automation -> Batch answer, but I am a programmer. I haven't touched ExtendScript nor scripted anything in CS, but I can certainly read about it. Any examples I can download or references to methods that would do a "Save As" very similar to the Jpeg Save For Web? Any links would be helpful.

You will find many examples at ps-scripts.com

Hi,
This is the UDF u have to write in Mapping,
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key =
DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
Using this u will get the File name into target side,In this UDF add the Time stamp.
Check this link for more details.

How to programmatically disable prompts for output file names in Acrobat X

My code to programmatically disable output file names (below) is not working on a Windows 7 64-bit machine using Acrobat Distiller X. It works perfectly on a Windows XP machine with Acrobat Distiller 8.
The latest API Reference I was able to find is dated June 2008. My logic follows this convention.
I have confirmed that the registry key is updated as specified below. I have also confirmed that I am able to write to the directory indicated.
Please provide any suggestions to resolve.
Thank You!

I remember seeing that the problem is thunking. A little more specifically, because it's a 32-bit driver but a 64-bit executable, there's a 32-bit system spooler process which will always show up as the EXE name.

How can I assign image file name from Main() class

I am trying to create library class which will be accessed and used by different applications (with different image files to be assigned). So, what image file to call should be determined by and in the Main class.
Here is the Main class
import org.me.lib.MyJNIWindowClass;
public class Main {
public Main() {
public static void main(String[] args) {
MyJNIWindowClass mw = new MyJNIWindowClass();
mw.s = "clock.gif";
And here is the library class
package org.me.lib;
public class MyJNIWindowClass {
public String s;
ImageIcon image = new ImageIcon("C:/Documents and Settings/Administrator/Desktop/" + s);
public MyJNIWindowClass() {
JLabel jl = new JLabel(image);
JFrame jf = new JFrame();
jf.add(jl);
jf.setVisible(true);
jf.pack();
I do understand that when I am making reference from main() method to MyJNIWindowClass() s first initialized to null and that is why clock could not be seen but how can I assign image file name from Main() class for library class without creating reference to Main() from MyJNIWindowClass()? As I said, I want this library class being accessed from different applications (means different Main() classes).
Thank you.

Your problem is one of timing. Consider this simple example.
public class Example {
    public String s;
    private String message = "Hello, " + s;
    public String toString() {
        return message;
    public static void main(String[] args) {
        Example ex = new Example();
        ex.s = "world";
        System.out.println(ex.toString());
}When this code is executed, the following happens in order:
1. new Example() is executed, causing an object to constructed. In particular:
2. field s is given value null (since no value is explicitly assigned.
3. field message is given value "Hello, null"
4. Back in method main, field s is now given value "world", but that
doesn't change message.
5. Finally, "Hello, null" is output.
The following fixes the above example:
public class Example {
    private String message;
    public Example(String name) {
        message = "Hello, " + name;
    public String toString() {
        return message;
    public static void main(String[] args) {
        Example ex = new Example("world");
        System.out.println(ex.toString());
}

Creating dynamical flat file name in mapping?

Hi.
I know about the variations on how to use an input parameter and/or sysdate to create a dynamic output file name in a mapping.
My challenge is nearly the same, but I cannot make OWB generate the correct code.
Problem:
- got a one column table that holds an identifier in a string field
- got a function that reads and returns said identifier
- imported function into OWB
- trying to use the function call in the Flat File Operator's Target Data File Name, e.g. fixedfilename||fn_get_id()||sysdate||'.ext
OWB creates the code:
UTL_FILE.FOPEN(
'my_location',
'fixedfilename'||fn_get_id()||'_'||SYSDATE||'.ext',
'w',
32767
However, when compiling the package code, it returns the warning:
ORA-06550: PACKAGE BODY, line 2214, column 29: PLS-00201: identifier 'FN_GET_ID' must be declared
which results in an error when trying to execute the mapping.
I've tried substituting the function call in the FOPEN call:
myId := fn_get_id();
UTL_FILE.FOPEN(
'my_location',
'fixedfilename'||myId||'_'||SYSDATE||'.ext',
'w',
32767
and this works fine, the mapping creates a file with the desired filename. But obviously not a good solution rewriting the generated code all the time....
Anyone solved something similar?
Could I use an input parameter and the autogenerated function GET_<PARAMETER>?
But can I set the value of an input parameter inside the very same mapping?
Regards,
-Haakon-

(It always helps writing out one's problems...)
I managed to get it working :-)
Added an input parameter to the mapping, and gave the outgroup variable a default value by calling my imported function.
Then concatenated the implicitly generated function (GET_PARAMETER) in the Target Data flat file name.
I now have a target file name that changes according to a departement id stored in a parameter table.

iam not able to create the text file with more than 16 fields.i have tried to create an out put file with 24 fields but i can only see 16 fields in it.so could any body help me in finding out how i can create an Output file with more than 16 fields in the file.
your help will be appreciated.
regards.
Varma

check your output definition....are you doing something like below? SAP will transfer 1024 bytes per line with GUI_DOWNLOAD.    After you download, how do you view the data? Be sure you're looking at the data with something that will show all 1024 bytes, and not jsut 256 or 512.
types: begin of outline,
           txt(1024),
         end of outline.
data: outtab type table of outline,
         ls_out type outline.
