Problem

Sometimes an FTPS SIT Push to a Mainframe might fail with the following error message:

501 Invalid data set name "xxxx.xxxx.xxxxx.test.1234.DC1212.XXXX". Use MVS Dsname conventions

Resolution

A possible solution is to rename the file on the file system on the ST's side, adding single quotes around it.

Example:

Original file name: xxxx.xxxx.xxxxx.test.1234.DC1212.XXXX

Modified file name: 'xxxx.xxxx.xxxxx.test.1234.DC1212.XXXX'

File transfer should be successful with that file name representation.
