Dynamic file name in case of .txt output files

Hi all,
I have a query related to dynamic file name scenario.
In case of IDOC-XI-FILE sceanrio,
<b>Is it possible to generate .txt file name based on Plant number like</b>
<b>%<Plantname>%_%<BusinessDay>_filename.txt</b>
<b>Note:I have implemneted this for .xml output files but I am not able to implement it for .txt output files .</b>
PLEASE HELP ME .
Regards
Prabhat

Hi Prabhat,
I think, the normal Dynamic File Name generation should work fine in your case also. Even if you perform Content Conversion, you can use Variable Name Substiution to create your Destination file name as, the name of the file is determined first and only then is the content converison perfromed.
for info on content conversion, I would suggest that you go through this thread and check my reply,

Setting up the File Name of email Attachment from Received File Name

Hello All,
I have to send the Received File in attachment to an Email if there is any exception. Here I can attach the file, but I cannot set the file name of attachment as the Received File Name. Is there anyway of doing this without using custom pipeline component.
Here I am using the Orchestration and SMTP Adapter.Any help is greatly appreciated.
Thanks

It might work if you use a custom pipeline component on your send port and in the Execute method populate the MIME.FileName property of the body part.
Something like:
public IBaseMessage Execute(IPipelineContext pc, IBaseMessage inmsg)
string filename = inmsg.Context.Read("ReceivedFileName", "http://schemas.microsoft.com/BizTalk/2003/file-properties");
inmsg.BodyPart.PartProperties.Write( "FileName", "http://schemas.microsoft.com/BizTalk/2003/mime-properties", "filename);
return inmsg;
You can take reference from similar post here
SMTP - Setting attachment filename
Anther good article with MIME is here
Setting attachment filename with the SMTP Adapter
For MIME case your SMTP message construct statement would be like below
multipartMessage.MessagePart_1= InMSG;
multipartMessage.MessagePart_2="This is message part2 as a string";
multipartMessage(SMTP.Subject) ="Email From Dynamic Port";
multipartMessage(SMTP.From) ="[email protected]";
multipartMessage(SMTP.SMTPHost) ="yoursmypserver.com";
multipartMessage.MessagePart_2(MIME.FileName) = "Attachment_Name";
multipartMessage(SMTP.SMTPAuthenticate) =0;

I have a question about extracting pages. When I do the function, adobe saves the individual files as "<file name><space><page number>", so the files look like this "filename 1.pdf", "filename 2.pdf", "filename 3.pdf". Without too many gory details, I am using excel to concatenate some data to dynamically build a hyperlink to these extraced files. It casues me problems, however, for the space to be the the file name. Is there any way to change the default behavoir of this function to perhaps use a dash or underscore instead of a space?

No, you can't change the default naming scheme. You can do it yourself if you extract the pages using a script instead of using the built-in command.

File importer detected an inconsistency in the file stucture of (file name). Reading and writing this file's metadata (XMP) has been disabled.

I have duplicated a project to work on another computer. The project opens fine but when I import new footage/audio files I get this message. "File importer detected an inconsistency in the file stucture of (file name). Reading and writing this file's metadata (XMP) has been disabled." Then I can't play my timeline and Premier Pro crashes. I have to force quit and restart my computer to continue working. What does this error really mean? How do you rectify?
Our workflow requires that we duplicate projects to make updates because we are frequently revising but need to keep original project unchanged and intact.

I have a similar issue and message , but occurs when I import AVI clips from OnLocation CS4 to Premier Pro CS4.

I just found an error in the file name for my Camera Raw Cache file. How do I correct it?

I just found an error in the file name for my camera raw cache file. The error is in my username. I don't know how to correct the error or if I should just leave it. I'm not sure where my cache file is stored on my computer. Any help would be appreciated.
Thank you

Since you are on a Mac if when you first set up your account you left out the i in Wilson nothing you do will change that. The REAL account name will always be alicewlson. Once an account is created you can't actually change the name of it. You can change the name that is displayed but not the REAL account name.
Simplest thing to do is stop worrying about it. Everything is as it should be, that is except Wilson being spelled without the i.

Script to insert file name into keywords field of same file

Hello,
search a solution, a Script or another, which writes the file name into keywords field of same file (Metadata: Description/Keywords) in "photoshop", "bridge" or better in "Lightroom" .
I found this topic from Mike Hale http://www.ps-scripts.com/bb/viewtopic.php?t=1330
It's possible this script to change this in such a way that it does this:

I have difficulty pasting text into the file name field(prefix only) while saving files.

OS: WinXP sp3
FF: 3.6.3
I have difficulty pasting text into the file name field (prefix only) while saving files. example: File name is Pic123.jpg and I want to rename it ABC123.jpg and I have ABC loaded into the WinXPsp3 clipboard. When I highlight\right-click\delete "Pic" then attempt to paste the ABC, I get either no reaction, or upon multiple paste attempts, the ABC is appended to the end of the file, after the extension, as "Pic123.jpgABC". If I delete this unwanted suffix, or repeat the process several times, eventually I can delete the unwanted portion of the prefix and paste the desired text. Sometimes it works fine first try, but mostly it takes several tries. I'm using Firefox 3.6.3 but the problem existed in whatever previous version I had too. This issue only occurs when using the delete/paste; I can always manually change the name by typing. Thank you for your help.

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

File name generated when saving a process file

When I choose to save a file (save as for instance) I get an odd
looking default file name with a ~ in it such as; ne6e29~1.l4p. Why?

Leo,
I agree, that is an odd file name. I am not sure where the "~" is coming from. I am using Lookout 5.1 on a Windows XP machine. If I open a new process and use the default process name "Process1", the same name is appears in the "File name:" field of the "Save Process File As..." window when I navigate to File >> Save As. Even if I choose another name for my process, that name is then used as the default file name when I go to "File >> Save As."
If you save your process with another name, such as "myprocess.l4p", does the same default name appear when you go to "File >> Save As"?
I have seen the "~" character used in other applications when a file name exceeds the maximum length but I do not recall having that problem on newer OSes like Windows 2000
or XP. I tried to save a process with a really long random file name on my machine and I was still unable to reproduce the behavior you are seeing.
What version of Lookout are you using and what OS are you running. If your process is running on an older OS or you are using an older version of Lookout, it may be that the file name is limited to fewer characters.

Target file name-'YYYYMMDD-HHMMSSMMM- test .txt

Hi Experts,
We have a requirement where we need target filename as 'YYYYMMDD-HHMMSSMMM-test.txt'. Kindly suggest can we get this filename without using Variable Substitution and Dynamic Configuration.
Regards,
Sudha

Hi Sudha,
If your requirement is to avoid using Variable Substitution and Dynamic Configuration, you can always use an Operating System Command After Processing that you will define in the Receiver Communication Channel. You can use it to change the file name of the file that just got created, and add the timestamp at the beginning.
Hope this helps,
Greg

Dynamic sender file name Pattern and collecting into one file

Hi Experts,
Could you please let me know how to achieve below scenario.
1)     File Directory: TEMP: files: test1,test2,ign1,ign2..etc.
2)     Get the files of pattern test*
3)     Received files test1, test2.
4)     Club contents of file Hemanth1, Hemanth2.
Ex: test1 contains------REC1
      test2 contains------REC2
OUTPUT FILE contains REC1,REC2.
5)     Pass OUTPUTFILE and filenames (test1,test2) to R/3.
PS: Please dont give references of blogs..I went through most of them could n't finad anything helpful.
My concern is how to collect files into one file and sending filename pattern..
Thanks in advance..

Vaildating File name with the data in the file using sender file adapter

Hi,
Below is the scenario
1)       Pick up files from a FTP server, the file name is dynamic, how do I put dynamic name in sender file adapter?
2)       Determine if the user correctly named the file based on data in the file.
a.       File naming structure that we will be concerned with is <company_code><accounting_time_period>.<extension>
b.      The company code and the time period in the file name have to match the data in the file.
i.      For example. If the file name is 1001_200712.csv and the data in the file is for company code 1005, time period 200712, the file is incorrectly named. Both values must be correct.
How do we do this?

Hi Sachin,
                As Rightly said by Krishna, You can not put Dynamic name in sender File Adapter .You have to provide the name of the file like "*.txt" in Sender Adapter and at runtime you can access this file name by using following UDF:
DynamicConfiguration conf = (DynamicConfiguration) container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String valueOld = conf.get(key);
return (valueOld);
As now you have picked up the file name at runtime.
Now concatenate source file fields Company_code and Accounting_timeperiod using "_" as delimiter in properties.Also concat the extension .Now you have required file name.
So using EQUALS standard function ,compare it with File Name fetched at runtime using above given UDF, and pass result as you desire to process further or not or to raise Alert to resend the file.
Thanks & Regards,
Anurag Garg
You can validate this file name in Mapping itself.

Sorry about the long lines.
As you can see, all input files saved in array called files, however when OpenFile1() function is called, it take input (fileName_in) as a single file not an array. I'm assuming this causes the exception.
When there's muptiple inputs, program should take each file from getFileName() to outputToFile() sequentially.
Does anybody have an idea to solve this?
Thanks a lot!!

you naming convention is confussing. you should follows Java naming convention..you have a getXXX but decalred the return type as "void"...get usully means to return something...
your code is doing too much..and hard to follows..
1. get the selected files
for each selected file
process the file and return the result
write out the result.
/** close the precious resource */
public void closeResource(Reader in){
    if (in != null){
        try{ in.close(); }
        catch (Exception e){}

public int getLineCount(File file) throws IOException{
    BufferedReader in = null;
    int lineCount = 0;
    try{
        in = new BufferedReader(new FileReader(file));
        while ((in.readLine() != null)
            lineCount++;
        return lineCount;
    finally{ closeResource (in); }
/** read the file */
public void processFile(File inFile, File outFile) throws IOException{
    BufferedReader in = null;
    StringBuffer result = new StringBuffer();
    try{
        in = new BufferedReader(new FileReader(inFile));
        String line = null;
        while ((in.readLine() != null){
            .. do something with the line
            result.append(....);
        writeToFile(outFile, result.toString());
    finally{ closeResource (in); }
public void writeToFile(File outFile, String result) throws IOException{
    PrintWriter out = null;
    try{
        out = new PrintWriter(new FileWriter(outFile, true)); // true for appending to the end of the file
        out.println(result);
    finally{ if (out != null){ try{ out.close(); } catch (Exception e){} } }
}
