File deliverable concern in FTP

Question

Hi All,
We have a scenario where we sending the files to FTP with comma delimeted.
Now requirement saying that : There is a another file (called .cksum) should write no.of records , filesize, filename in 2nd file based onfirst file(File1.txt) records.
Ex :
The Checksum file contains number of records, file size and the file name .
The checksum file for file2.cksum contains the following information
1425702217      387293337       File1.txt
Please share your ideas on this , how do we achieve this 2nd file with that information.
Thanks,
Shankar

For multimapping steps use this blog... /people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible
Now, since you already have the data type for your csv structure, so now just create the data type for checksumfile.
The data type for checkusm should be made with just one field (as per your example given for checksum values) and then use Dynamic Configuration to get the FileNmae & Filesize. For counting the records just simply use count function and count all records (use RemoveContext).
Here is the Dynamic Configuration code for FileName & size..
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","SourceFileSize");
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String fileSize = conf.get(key);
String fileName = conf.get(key1);
String output = fileSize + "" + fileName;
return output;
After counting the records just concatenate it with the output of the above udf and pass it to the target of your second mapping structure..
Rest of the steps you can see in above blog..
