How to handle /n in CSV

Hi,
I have 5th field in my data file which contains new line character and client want to preserve this character.
My data file is CSV which means that record will be terminated by /n. But since new line character is coming in one of the field, it is considering it as a record termination.
How can I handle this situation.?

I have new line character in long description column

Need help on how to handle zip & text/csv as a resposne payload from Concur RestWebservice

Hi All,
We are getting zip(if there are multiple files) and test/csv(single file) as a response payload from the concur rest API and need your help on how to handle in NWBPM and SAP PO.
Zip response coming in response looks like below -
PKÀ˜F7extract_attendee_detail_p0600908soav_20150424022159.txts� rt©1204Õ50Ñ52©1¨áåPKzà@ÆPKÀ˜F2extract_CES_SAE_v3_p0600908soav_20150424022148.txts� rt©1204Õ50Ñ52©1¨©1ãåPKåëŠŸPKÀ˜Fzà
Text/csv response looks like below -
Extract|2015-24-40|20|0
Need you help on how to handle the zip content response.
Also need help on how to handle when text/csv response comes and when zip response comes.
As per the scenario, there are 4 calls to be made and we are using NWBPM and in the last call the actual respons (text/csv or zip) will come.
Please provide your inputs.
Thanks

Hi Aaron,
Thanks for your reply.
I tried with Payload zip bean and the java mapping as mentioned in the response mapping of OM.
Payload zip bean - Zip zip.mode unzip
I am getting the error below in the receiver rest channel -
"Transmitting the message using connection JPR failed, due to: com.sap.aii.af.lib.mp.module.ModuleException: Zip: error occured during processing: java.util.zip.ZipException: invalid stored block lengths"
Java Mapping - used the java mapping in the response of Operation mapping
Here also i am seeing the same error in the channel log as it is synchronous step and the message got cancelled.
"Transmitting the message using connection JPR failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error encountered while executing mapping: com.sap.aii.af.service.mapping.MappingException: Mapping failed in runtimeApplication mapping program com/equalize/xpi/esr/mapping/java/UnzipAndAttach throws a stream transformation exception: Exception: invalid stored block lengths"
The below is the response i am seeing and is it proper zip response payload(any encryption) , kindly advise.

How to handle a comma in a field in CSV file during FCC ?

Hi,
I am having a requirement where we have to convert a CSV file into XML using File Content Conversion . The issue is one of the field in the file is having a comma inside. So the XML parser is taking it as a field separator and throwing an error.
The contents of the file are as follows:
"02975859","New Key","9","Failed, rejected by RTI server"
How to handle a comma inside field "Failed, rejected by RTI server".
Any help would be appreciated.

How to generate a second csv file with different report columns selected?

Hi. Everybody:
How to generate a second csv file with different report columns selected?
The first csv file is easy (report attributes -> report export -> enable CSV output Yes). However, our users demand 2 csv files with different report columns selected to meet their different needs.
(The users don't want to have one csv file with all report columns included. They just want to get whatever they need directly, no extra columns)
Thank you for any help!
MZ

Hello,
I'm doing it usually. Typically example would be in the report only the column "FIRST_NAME" and "LAST_NAME" displayed whereas
in the csv exported with the UTL_FILE the complete address (street, housenumber, additions, zip, town, state ... ) is written, these things are needed e.g. the form letters.
You do not need another page, just an additional button named e.g. "export_to_csv" on your report page.
The csv export itself is handled from a plsql procedure "stored procedure" ( I like to have business logic outside of apex) which is invoked by pressing the button "export_to_csv". Of course the stored procedure can handle also parameters
An example code would be something like
PROCEDURE srn_brief_mitglieder (
     p_start_mg_nr IN NUMBER,
     p_ende_mg_nr IN NUMBER
AS
export_file          UTL_FILE.FILE_TYPE;

Hi Uday,
Its occurs because you're trying to access a objects with null reference. Or you forgot to create an instance or an error occurs during the instance creation. So You should put all your "Procedures and business logic" inside a Try/catch block. as follow.

How to handle null values in RTF templates

Hi - I have two groups in a report for different SQL and two formulas for each group, CF_ELE_CNT and CF_ELE_CNT1. In the template I use the below code to print or not print a section.
<?if:number(CF_ELE_CNT +CF_ELE_CNT1) >0?>
The problem is when there is no data in the second group its not creating the XML tag for CF_ELE_CNT1, though CF_ELE_CNT has 13, it still does not print that partucular section. If I remove CF_ELE_CNT1 from the condition it works fine. I was wondering how to handle this.
Any help would be appreciated!!
Thanks,
Rav

Hey Rav,
You can add a check to identify it the element/tag is present or not
<?if:(CF_ELE_CNT1)?> will give true, if the element is present otherwise falsesince you are adding the two elements, you have to add a or condition.
<?if:(CF_ELE_CNT and number(CF_ELE_CNT) >0 ) or ( CF_ELE_CNT1 and CF_ELE_CNT1 >0)?>

Thoughts on how LabVIEW handles checkout of file from SCC when file already open

When you already have a file/project open in LabVIEW and it is set to read only because you haven't checked it out, you can go into SCC and do a checkout then save the file immediately. The issue with this is, if your local copy doesn't match the copy in SCC, you will probably be overwriting changes. Sometimes this is convenient because if you have ever edited a MS Word file and then gone to save and it won't let you because it was opened as read-only...then that sucks because you either lose your work, or have to do a copy of the entire word file->close the program->re-open as writable, then paste. This can be avoided with the "LabVIEW way", but the "MS Word" way seems much safer because it forces you to conscioiusly make the file writable (by either checking it out or manually write clicking and changing to writable) BEFORE opening it. I just wanted people's opinions on how LabVIEW handles this, and if there would be a better way.

How to handle password changes if we implement singlesignon between BO& BI7

Hi,
As we know ,we can implement single signon between BO and SAP BI 7, by importing roles and users through CMC and by selecting the option "Use Single signon during report refresh time".
My doubt here is, When we import roles from SAP and Auto import the users, is it only the SAP usernames that are stored in BO repository or both username and password. If second case holds true then how to handle/manage password change for a user who is already imported in BO sometime back?
Would the password changes be reflected automatically in BO?
Please guide me if you think that I'm thinking in a wrong direction.

Hi Naresh,
password changes are reflected automatically in BO. BO just forwards the data to the SAP side and it does the real authentification.
Regards,
Stratos
PS: Keep in mind that you cannot change the SAP password on the BO login screen if your SAP password has expired. You have to do this with the SAP client (SAP GUI)
