somenath,

Variable substitution is used when u have to access the payload for some need like, if you have the filename or dirname in the message itself.

to use,

enable the variable substitution, create a variable and specify the XPATH for the particular field then use it in filename/dir as said by others.

Hi,

Variable substitution allows you to name your target file dynamically with some value in the message payload.

You can also use Adapter Specific Message attributes instead of Variable sub. It allows you better control.

Hi Somenath

Variable substitution is used to get some parameters availables in comm channel comming from desing.

For example, you can use different directory or filenames using this variables.

In a target directory :/%variable%

Or File name scheme : file_%variable%.txt

Kind regards,

Hi,

Variable substitution

When you specify the target directory and file name schema, you now have the option of setting variables and defining them in a table. The variables are replaced by elements from the XML structure at runtime.

Contrary to the description in the documentation, you cannot yet replace with attributes from the XI message header. Do not use the prefix during variable substitution
