Hi,

Thanks for all reply. All the setting was done refer to the blog https://www.sdn.sap.com/irj/sdn/wiki?path=/display/xi/flat%2bfile%2bto%2bflat%2bfile which i think detail enough. Anyone have an idea for this null pointer error??

Thanks

There could be several reasons of null pointer.

So you are using FCC in your CC as per this link. Tell me in which source directory you are putting your file. It should be in XI server directory whch you can see by transaction code AL11.

Can you confirm that the sourc file is on XI server directory and you can see it by AL11?

Hi,

Thanks for reply. The nullpointer problem was solve after i change the source directory to others. Now there is another problem Could not delete file 'C:\XI_FILES\SENDER\xi_output.txt' after processing. Any idea ??

Thanks

[Former Member]

The path in File Adapter should be like \XI_FILES\SENDER under Source Directory

and the file name should be xi_output.txt

make sure the file name is exactly same in the source dir in XI server.

Hello,

Change the test file permission to 777, XI was able to pick up and delete the file, or change the file user permission to all.

HI

Please check the mandatory fields for the file sender. This error mostly arrives due to incorrect configuration of fields.

Are you using wildcard in place of filename.. this can also be a potential reason

Hi,

Also make sure to fill in all mandatory fields present in the sender communication channel.

Do let us know the trace or audit log on the error.
