■Specification
The “Write Fixed-Length File” process is a process when it writes a multi-byte string that exceeds a length specified in the structure definition, it writes only a string that can fit the "length" and fills the rest with padding characters.
From the specification limits of the Help "Write Fixed-Length File” process
-----
When it writes, if the data does not fit exactly into a specified length field due to a result of the string operation (left / right alignment, padding, etc.), the space that did not fit correctly is filled with "padding characters".
-----
■About Cause
When filling with "padding characters", the following error will occur if the part that did not fit in the "length" is 1 and a full-width character is specified for "padding characters".
