Header information in text files

I have a VI which logs information every ten minutes into a text file. I want to add a header to the beginning of the file only once, not every ten minutes as with the rest of the information. How can I accomplish this.

At the beginning of your test create the file outside a loop and write the header information to it. Then inside the loop, keep the file open then every 10 minutes append your data to it, then close the file when finished.

How can I add a header to a text file without mapping? [Using only ID]

Hi Experts,
I am doing a scenario in which I want to add a dynamic header to a text file, due to the complications related to the structure, I dont want to create a message type, data type etc so I cant use mapping.
I want to do all the manipuations in Integration Directory itself.
Can you all please help me out in this?
Thanks in advance

Hi Experts,
I am new to XI, so only elaborate answers would help me
This is the specific requirement i want;
There is a 'source text file' which is a collection of 1000+ records, I want to make a 'target file' which is a combination of 2 fields, one field will be the dynamically generated name [for the target file] and the other field will be the whole 'source file' content.
From the last response for my question, I understand the dynamic file generation part can be done using java mapping.
Is there anyway by which I can get in the whole content of the source file into a field in the target file?
Thanks in Advance

Adding Header to a TEXT File

Hi All,
I am downloading some data into a text file using GUI_DOWNLOAD FM.
Is there any way that i can add a header line on top of the file? In excel file, it is possible, but how do i do it for a *.txt file?

Is it possible to export all information (metadata, list of pictures within each album or project) about ALL pictures in Aperture to text files, in a single operation?

I have downloaded a trial version of Aperture because I would like to switch from using Picasa and gimp to using Aperture. I already know that I want to use Aperture, and that I cannot learn how in 30 days. I want to use the 30 days to see if I can solve a different problem: bulk export of all information except edits and versions from Aperture.
I want to avoid locking information (other than than the edits and version information that Aperture maintains) about my photos into any one piece of software.
Picasa stores a copy of almost all its information in text filies (mostly XML or .ini format) that are scattered through its picture library. These files can be scanned and found by use of Mac OS X tools that are availabe in Terminal (at the bash command line). All of the information about albums, faces, etc can be exported by a single command (after wtiting the progams that the command will initiate. I have not yest found any similar files in Aperture.
Aperture supports the export of EXIF and IPTC metadata, but only for selected photos, and does not appear to support the export of other information at all.
What I would like to do with a single operation, from either Aperture or Terminal, is to export the entire arrangement of phost ins albums and projects, lists of albums, projects and phots with all metadata (including added keywords) attached to each, and for referenced photos, the external file name. I do not care if would be in one file or many different text files, because Mac OS X provides all the tools I would need to extract the information I would want from any number of text files.
This would allow me to reconstruct all of the information about my photos (except for edits and versions) outside Aperture, and to use that info in a database outside Aperture. I would then be able to use Aperture while still being able to do everything that I could do with Picasa.
The most helpful form of an answer to this question might be a list of places to look in the Apple support and Apple developer documentation. It is difficult to teach me anything complicated, but I am fairly good at figuring out things from documentation.

The following script recursively lists the content of an Aperture library. The output is simple, for demonstration puposes, but could be modified to XML. If the XML were that of a PLIST, the Apple Property List viewer oculd be used to diaplsy the output.
A simlar script produces all of the keywords and tags for all of the images in Aperture.
The scripts run much faster in the shell than in the AppleScript Editor bcause the shwll produces no debugging or monitoring information.

Header and Item Texts for Sales Order

Hi,
Can any one help me on Header Text and Item Text...........
STXH & STXL
TDOBJECT :__________
TDID:_____________
TDNAME :_______________
Regards,
Raghunath.S

Hi
Double click on the related text
it will open Text editor
from Menu GOTO-> header
for SO HEADER Texts
then you see the 4 paramters like OBJECT (VBBK),ID,OBJECTNAME (sales Order No) and LANG
FOR SO ITEM texts
OBJECT (VBBP table), ID, OBJECTNAME(SO no plus ITEM No) and LANG
You have to pass these 4 parameters to READ_TEXT fun module to fetch the corresponding texts
see the doc on READ_TEXT
READ_TEXT
READ_TEXT provides a text for the application program in the specified work areas.
The function module reads the desired text from the text file, the text memory, or the archive. You must fully specify the text using OBJECT, NAME, ID, and LANGUAGE. An internal work area can hold only one text; therefore, generic specifications are not allowed with these options.
After successful reading, the system places header information and text lines into the work areas specified with HEADER and LINES.
If a reference text is used, SAPscript automatically processes the reference chain and provides the text lines found in the text at the end of the chain. If an error occurs, the system leaves the function module and triggers the exception REFERENCE_CHECK.
Function call:
CALL FUNCTION 'READ_TEXT'
EXPORTING CLIENT = SY-MANDT
OBJECT = ?...
NAME = ?...
ID = ?...
LANGUAGE = ?...
ARCHIVE_HANDLE = 0
IMPORTING HEADER =
TABLES LINES = ?...
EXCEPTIONS ID =
LANGUAGE =
NAME =
NOT_FOUND =
OBJECT =
REFERENCE_CHECK =
WRONG_ACCESS_TO_ARCHIVE =
Export parameters:
CLIENT
Specify the client under which the text is stored. If you omit this parameter, the system uses the current client as default.
Reference field: SY-MANDT
Default value: SY-MANDT
OBJECT
Enter the name of the text object to which the text is allocated. Table TTXOB contains the valid objects.
Reference field: THEAD-TDOBJECT
NAME
Enter the name of the text module. The name may be up to 70 characters long. Its internal structure depends on the text object used.
Reference field: THEAD-TDNAME
ID
Enter the text ID of the text module. Table TTXID contains the valid text IDs, depending on the text object.
Reference field: THEAD-TDID
LANGUAGE
Enter the language key of the text module. The system accepts only languages that are defined in table T002.
Reference field: THEAD-TDSPRAS
ARCHIVE_HANDLE
If you want to read the text from the archive, you must enter a handle here. The system uses it to access the archive. You can create the handle using the function module ACHIVE_OPEN_FOR_READ.
The value '0' indicates that you do not want to read the text from the archive.
Reference field: SY-TABIX
Default value: 0
Import parameters:
HEADER
If the system finds the desired text, it returns the text header in this parameter.
Structure: THEAD
Table parameters:
LINES
The table contains all text lines that belong to the text read.
Structure: TLINE
Exceptions:
ID
The text ID specified in the parameter ID does not exist in table TTXID. It must be defined there together with the object of the text module.
LANGUAGE
The parameter LANGUAGE contains a language key that does not exist in table T002.
NAME
The parameter NAME contains the name of a text module that does not correspond to the SAPscript conventions.
Possible errors:
The field contains only blanks.
The field contains the invalid characters * or ,.
OBJECT
The parameter OBJECT contains the name of a text object that does not exist in table TTXOB.
NOT_FOUND
The system did not find the specified text module.
REFERENCE_CHECK
The text module to be read has no text lines of its own but refers to the lines of another text module. This reference chain can include several levels. For the current text, the chain is interrupted, that is, one of the text modules referred to in the chain no longer exists.
WRONG_ACCESS_ TO_ARCHIVE
The exception WRONG_ACCESS_TO_ARCHIVE is triggered if an archive is accessed using an incorrect or non-existing archive handle or an incorrect mode (that is, read if the archive is open for writing or vice versa).

Fill a text file from java code

Hello,
I've written a java code to insert some informations in a database and
I also want to save the same informations in text files (.txt).
Thanks you for your suggestions or your advice of a tutorial that can help me to perform successfully this task.
J.S.

Writing to a file is pretty easy in Java. A simple way is to use the PrintStream class.import java.io.*;
public class MyClass {
public static void main(String[] arg) throws IOException {
    PrintStream ps=new PrintStream(new FileOutputStream(new File("someTextFile.txt")));
    //now use println(String) to write lines of text to the file
    ps.println("This is a line in the file");
    //always close the PrintStream when finished
    ps.close();
}Alternatively, for a good tutorial, click the 'Tutorials' link in the left column on this page.

Import data from text file

We are trying to import data from a text file into fields in a form using the importTextData method for the Doc object. The script we are using looks like this:
var doc = event.target;
var returnCode = doc.importTextData("datafile.txt",0);
The text file "datafile.txt" contains tab separated values in a header row (which corresonds to field names in the form) followed by tab separated datarows - all according to instructions in the API.
The returnCode will result in an integer value, which in our case represent "Error: Invalid Row". It would help us a lot if anyone could give us a hint on what may be wrong or even better post a working solution.
We have also tried using the importTextData method without any parameters (the user is then prompted to select the text file and then the specific row) but the result remains the same. The fields in the form are not populated with data and the message "Error: Invalid Row" is returned.
Annika Lindqvist

The problem you're experiencing is that importTextData is an Acrobat API call. As such, it executes on the AcroForm field equivalents to the XFA fields you've placed on the form. What's not indicated in the API for importTextData is that the names in the fields in the header of the text file must be the
full AcroForm SOM expression.
I've created a working sample to explain this.
First, I created a form with a table with one row in it containing 3 columns named FirstName, LastName and Country.
Then I created a data.txt file like this:
FirstName LastName Country
Fred Jones USA
Kyle Francis Canada
Sam Roberts UK
I then placed a button on the form which calls "event.target.importTextData();" and ran the form in Preview.
Of course, when I selected a row for import, nothing happened.
I then used the "Avanced | Forms | Export Data from Form..." menu option in Acrobat after filling-in the fields in the table with some text and looked at the generated text file (note that you have to specify text as the output format). In there, I was able to figure-out what the full AcroFrom SOM expression was for each field I wanted to import data into.
I changed my data file to look like this:
form1[0].#subform[0].Table1[0].Row1[0].FirstName[0] form1[0].#subform[0].Table1[0].Row1[0].LastName[0] form1[0].#subform[0].Table1[0].Row1[0].Country[0]
Fred Jones USA
Kyle Francis Canada
Sam Roberts UK
Afther that, importTextData worked as expected without any errors.

 dateofconfig = rs.getString("dateofConfig");
 System.out.println(request + " " + domain_name + " " + dateofconfig);
 data.add(request + " " + domain_name + " " + dateofconfig);
 System.out.println("before calling method");
 writeToFile(data, "c:/Employee.txt");
 System.out.println("file created successfull");

Can anyone help me to create header and fooder in text file.Well you plainly have the code to write the file contents; and furthermore your report seems to be contained in a List called 'data'. Why not just add the header and footer lines to it? I'd also suggest making 'data' a LinkedList. That way you can add the header afterwards with no performance hit, just in case the information it contains isn't available at the start of your report loop.

Recovering a deleted bookmark file with 'Rescue my files' need header information of the .json file

I've reformatted c drive and forgot to keep bookmark backup file. So I'm trying to recover, but the bookmark is a .json type file and I need to add this to the list of files Rescue My Files recognises. To do this I need to input the file header information. Does anybody know how to get the file header information for a .json file

A JSON backup is a text file that contains data in JavaScript Object Notation format and doesn't have a specific header like an HTML backup has. 
The file should start with: <nowiki>{"title":"","id":1,"dateAdded":</nowiki> 
All following data likes dates is specific to each backup.

How can I include the Header Information....for a File to IDOC Scenario

Hi,
I made a File to IDOC Scenario with DEBMDM06 for MDM>XI>SAP R/3. The Header Information in the XML File which is at the XI end is Missing. For that reason In Tcode SXMB_MONI we are getting an Error that "HEADER Information Missing: Message should Start with EDI_DC40" i.e the Header Information.
My Question is that whether we can do some changes in the Message mapping Step in the Integration Repository. I HardCoded the Few mandatory Fields that were there but it Again gave me the Same Error as above.
Can you please Suggest some Solution for this. Since the data is Coming in from MDM part the Header information is not there but It actually Important as it has got all the Port Information.
Kindly Inform me some Solutions.
Thanks & Regards
Somnath

Hi Suraj,
Thanks for ur Reply, but Since we are Doing a File to IDOC Scenario the IDOC DEBMDM is on the Right Side in Message Mapping and as U know it is Mandatory to Map an IDOC on the Right Part. EDI_DC40 is coming as it is there in the IDOC but our XML File Does not have that. If we Don't Map then it Becomes RED, which is an Error.
Furthermore in the Receiver Agreement we have put the Necessary Details such as Sender Service and Receiver Service along with the IDOC Communication Channels.
Can U give as a Better Insight on this Note how to check the Header Part as it is mandatory to MAP.We also tried to HARDCODE it by putting those Values and Mapping them to a Constant but it is Giving the Same Error.
Thanks and Regards
Somnath

No, I am not asking how to know the column name.
I am questioning why go through all the hassles to determine the column names, while they are already known.
When the user prepares the query to pass on to dump_csv():
SELECT Start_Date,
Num_Logs,
to_char(Round(Num_Logs * (Vl.Bytes / (1024 * 1024)),2),''999999999'') AS Mbytes,
Vl.Bytes / (1024*1024) AS RSize
FROM ...
he obviously specifies/knows the column names. (It's not like he was doing select * ...)But what if he was doing select *? And why hard code column names for this query and then have to change them if the query changes when you can write it to be completely dynamic?

Is it possible to import a Fixed Text file that does not have a header?

I'm trying to import a Fixed Text file through Import Manager, but the text file I am receiving does not have a header on it (the first row is valid data). When I try importing this, Import Manager uses the first row of data as the headings. Is there any way to turn this off and tell Import Manager there is no header data in the file?
Thanks!

Hi Ryan ,ur requirement can be met only when u import the file as ODBC .for this follow the below steps.
1)Go to control panel,in ur settings,select administrative tools
2) In that select DATA SOURCE(ODBC ).
3)Go to SYSTEM DSN tab select tab .
4)Select ur file type MICROSOFT TEST DRIVER (.txt,.csv)
5)Double click on "Import DSN" and in the blank give the name of DATA SOURCE NAME any name u want to give.
6)Uncheck the use current directory box and select the directory ur file is it will automatically show ur source file select it and click ok.
7) Now when u import ur file as ODBC give the name of ur DATA source name which u have given and it will show ur file in the source preview itself .
In this way u can import ur file as ODBC.
Hope this may help u.

Add header line to the text file in receiver file adapter

Hello Experts,
I have to add a new line to the text file generated at the receiver end.
My structure is
Record
 Item......0-unbounded
 field1
 field2
 field3
I have defined below parameters in receiver FCC.
RecordSet Structure : Record,Item
Item.fieldSeparator : ;
Record.fieldSeparator : nl
Record.endSeparator : '0x0D''0x0A' ( this is to get a carriage return at the end of the file)
Item.addHeaderLine : 1
With the above configuration, i am getting the desired output with NO header line.
Please help.
Thanks,
Swetha.

Hi, it looks like that the headerline "specification is only permitted if exactly one structure is defined." Please check [SAP help under Define Parameters for Recordset Structures|http://help.sap.com/saphelp_nw73/helpdata/en/44/686e687f2a6d12e10000000a1553f6/frameset.htm].
One solution would be to generate the header fields in the message payload. Generate an additional first line containing the header names, e.g.
<Item>
<field1>Header1
<field2>Header2
<field3>Header3

Header in text file.

Hi expert,
wn i m downloading a text file into presentation server , hw can i add header there for heading of the particular fieds which is showing in file.plz suggest.
thanx and regards...
sunil.

hello,
you can try doing as mentioned above
however, in some cases, the datatype of the internal table may not allow you to entire the text header string that you need
in such cases you can use this method
what i have done here, is to make a simple internal table with text values to insert the text
i used that table with the FM first
then i called the function module again and passed the data
in the second call, i set the append parameter to 'X'.
types: begin of header_type,
field1(20),
field2(20),
field3(20),
end of header_type.
data: it_header type header_type occurs 0 with header line.
it_header-field1 = 'field_1'.
it_header-field2 = 'field_2'.
it_header-field3 = 'field_3'.
append it_header.

Oracle Alerts - Suppressing Mime-Header information in plain text emails

Hi there
Is there a way to suppress Mime-header information at the top of an alert email? I mean this stuff:
>
Mime-Version: 1.0
Content-Type: multipart/mixed;
boundary="----=_Part_17_6226724.1264085542237"
Content-Language: en
X-oracle-workflow-nid: ALR[1/0000@DEVE]
------=_Part_17_6226724.1264085542237
Content-Type: text/plain; charset=ISO-8859-15
Content-Transfer-Encoding: 7bit
Content-Language: en
For some reason, it is appearing in some emails, but not others, and detracts from the readability of the alert text.
Any help appreciated.
Regards
CK
