Read .csv file to XI and convert to IDOC

Hi XI Gurus,
We have a requirement at work where we need to import .csv files to XI ehich then XI converts it to xml and posts an IDOC to SAP. I have tried creating this in XI with File Adapter with File Content Conversion.
I gave all the things required for File Content Conversion but still my .csv file is not being picked up and read by XI. Iam not sure why this is happening but can anayone please help me with this.
Also please do let me know if anyone has a tutorial related to this scenario.
Thanks,
Mayuresh.

Hi All,
I tried checking the error via Run Time Workbench (RWB) and going to Communication Channel Monitoring. It shows that there are some errors in the Communication Channel but when i go inside it does not open an error window for me containing the error details.
Just wanted to explain my file structure and the settings i have done in the 'File Content Conversion' of the 'File Adapter' so that you guys can tell me where i am wrong:
Message Type: VENDOR_MT
VENDOR_MT
    VendorNumber
    LastName
    SearchTerm
    Currency
Address
      Street
      City
      Zip
      Country
I am using IDOC receiver at the other end (CREMAS.CREMAS03).
CSV File Structure: (Sample)
34567, Reed, Jon, AUD, Smith Street, Melbourne, 3066, AU
The settings that i have used in the File Adapter (Content Conversion tab) are:
RecordSet Structure: VendorNumber, LastName, SearchTerm, Currency, Street, City, Zip, Country
RecordSet Sequence: Ascending
ignoreRecordSetName: true
Vendor_MT.fieldNames: VendorNumber, LastName, SearchTerm, Currency
Vendor_MT.keyFieldValue: 01
Vendor_MT.fieldSeperator: ','
Vendor_MT.endSeperator: nl
Address.fieldNames: Street, City, Zip, Country
Address.keyFieldValue: 02
Address.fieldSeperator: ','
Address.endSeperator: nl
Please do let me know if the communicatioon channel settings i have made are correct. Also let me know if i am missing some major setting.
Thanks,
Mayuresh.

Reading Flat File in Inbound and Converting it to a Idoc

Hi
We are stuck with a situation where in we get a ASN file from Mainframe to XI . XI just reroutes it to SAP and puts the file on Application server. Now R/3 has to read that ASN File and has to split it according to the Invoices and create Idocs for PO's as per the invoice Numbers. (We have a program which splits the incoming file into different Files depending on the Invoices)
Now My doubt here is how can i get a Idoc triggered after the File has been read and split in the R/3.
I checked Transaction WE16 , Prog. RSEINB00 but couldnt get a understanding .
Please suggest.
regards
Vikas Chaudhary

Hi Shiva,
Thanks for a response .
But as per my Functional Consultant ; PI's Role should be limited only to reroute the file and store it on Application Server .
R/3 Picks up that file and then splits it based on the Invoice Number; and again stores it in the application server.
Then R/3 Should Pick it up again one by one and convert to Idocs .
ASN to be splitted into Diff. Invoices . Once Splitted. Each Invoice Creates a PO . Once a PO is created Goods Reciept should be done. And after the Goods Reciept is done Service Entry Sheet needs to be created too.
A Query Again : I donn think this can be done via One Message Type. I am also lookin out for using one msg. type for creating a PO and other activities can be done by extending a existing msg. type.

Using Lightroom 4 w/ Windows 7. Recently started shooting w/ Sony camera .arw files. Lightroom cannot read the files. Loaded Adobe converter program onto the computer and this program cannot read the files either. Any suggestions?

Question about reading csv file into internal table

Some one (thanks those nice guys!) in this forum have suggested me to use FM KCD_CSV_FILE_TO_INTERN_CONVERT to read csv file into internal table. However, it can be used to read a local file only.
I would like to ask how can I read a CSV file into internal table from files in application server?
I can't simply use SPLIT as there may be comma in the content. e.g.
"abc","aaa,ab",10,"bbc"
My expected output:
abc
aaa,ab
10
bbb
Thanks again for your help.

Read from file, compare string and return a part

Hello, is there a reasonable good way to read text file containing information, and if string comparison is successfull, return a nother part of the string.
What i have done so far:
set file_name to (path to desktop as text) & "filename.txt"
set F to open for access tiedosto with write permission
set file_information to (read F)
close access F
(i will be moving this to Application Support/Appname/ when i figure it out).
The data in the file is in following format
12234567890Name1
98765432123Name2
92347928347Name3
What im stuck now is:
I need to compare each line the 10 numbers with search string, if match is found, the name part should be returned.
Any idea's?

You already read in the text file, so you need to put the data thru a repeat loop:
repeat with name_part in paragraphs of file_information
-- ((character 1 thru 10 of name_part) as string) is the first 10 digits of name part
if ((character 1 thru 10 of name_part) as string) is search_string then return name_part
end

File Adapter - Reading 2 files from sender and one file to receiver

All - I am looking for a best solution for reading two files from sender and generating one file to the receiver.
Here is the scenario
Sender file s - A is a master file. B is a detail file; B will have a one to many records for each record of File A.. that is the relation ship between 2 files.. I am looking for a better solution to
Example
Input:
File A will have a record like "summary1 ABC 1234"
File B will have a record like "Detailfor Summary1 CDF 8679"
Output:
File C shall have a record "consolidatedofSummary&Detail ABC 1234 8679"
1) read records of master row and detail row from these 2 files
2) do the mapping to the receiver output format which it is creating for records with some harcoded values and based on the values from master and detail rows of sender file
if I can accomblish reading sender files and do the mapping to the receiver , assume that mapping to the receiver format would not be cumbersome.
please help me...
Thanks

Hi Gopal,
Ur approach to the interface is perfect.... Go ahead.
For selecting multiple files in source use Advanced Selection for files.. and specify the directory paths and also the file name shema...
This will fetch the 2 files into the integration engine... then u map the 2 source files to one target file(2:1 mapping).
Specify accordingly the receiver side FCC and test it end to end...
If u face any prblm post here... some1 will help u out..

SQL server 2014 and VS 2013 - Dataflow task, read CSV file and insert data to SQL table

Hello everyone,
I was assigned a work item wherein, I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current
file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.
On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file. Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?
I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns
in it. These files needs to be migrated to SQL tables using the optimum way.
Does anybody know which is the best way to setup the Dataflow task for this requirement?
Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
Any help would be much appreciated. It's very urgent.
Thanks, <b>Ankit Shah</b> <hr> Inkey Solutions, India. <hr> Microsoft Certified Business Management Solutions Professionals <hr> http://ankit.inkeysolutions.com

The standard Data Flow Task supports only static metadata defined during design time. I would recommend you check the commercial COZYROC
Data Flow Task Plus. It is an extension of the standard Data Flow Task and it supports dynamic metadata at runtime. You can process all your input CSV files using a single Data Flow Task
Plus. No programming skills are required.

Read CSV File and parse it

Hi.
I have a .csv file on my filesystem.
Could you post few code to read it from filesystem and parse every rows in it?
Thanks a lot.

External tables are far easier to use... e.g.
I have a file on my server in a folder c:\mydata called test.txt which is a comma seperated file...

3,"Jim",50As sys user:
CREATE OR REPLACE DIRECTORY TEST_DIR AS "c:\mydata";
GRANT READ, WRITE ON DIRECTORY TEST_DIR TO myuser;Note: creates a directory object, pointing to a directory on the server and must exist on the server (it doesn't create the physical directory).
As myuser:

Read .csv File and Update DB

I have a .csv file with about 11 columns and multiple rows.
I need to read this file and from each row extract the first
4 columns and update my local database.
If the value if 1st column (unique#) is already in DB do an
Update else do an Insert.
How do I read this .csv file and accomplish this goal?

You read the file with <cffile>
It then becomes nested lists. For the outer list, your
delimiter is chr(10). Each list item is a row from your file. For
your inner list, the delimiter is a comma.
That should get you started. Details list functions and
<cffile> are in the cfml reference manual. If you don't have
one, the internet does.

Powershell read CSV file line by line and only first header

I have a CSV file, which reads like this:
read, book
read1, book1
read2, book2
I want to read only the first value, before comma one line at time,
meaning first time it will be
read
read1
read2
no headers and i want to pass that value to a variable for a if condition.
I have script it read line by line but it reads both values before coma and after line by line, so instead of having three values i'm ending with 6 values.
$file = Import-CSV c:\script\server.csv
$file | ForEach-Object {
foreach ($property in $_.PSObject.Properties)
$property.Name
$property.Value
#replace = $property.Value

If you can work with headers then do so as it will make your life easier.
with a csv file called server.csv like this:
headername1, headername2
read, book
read1, book1,
read2, book2
and this bit of code
$file = Import-CSV c:\script\server.csv
#output to host, file or directly pipe the command above.
foreach($cell in $file.headername1){ if($cell -eq $something){ }}
will evaluate the content of each cell to $something.
This is because Powershell will grab the first row and claim that as a header name.
So whatever you put in cell A1 in excell will end up as name of the first collumn and its corresponding property (e.g. $file.A1 oor $file.headername1 if you will).
