line length limit for receiver vda file

Hello,

We have idoc to vda integration. The length of a vda file must be divisible by 128.

Also the each line must be 128 length or fewer in vda file.

We use idoc sender adapter and file receiver adapter.

In file receiver adapter we use module configuration

localejbs/VdaConverterModule (for xml to vda convert)

How can we configure module parameters for configuration of each line length?

Regards,

Nurhan
