Variable substitution in short: This allows you to name your target file dynamically with some value in the msg payload.

P.S: Try Adapter Specific Msg attributes instead of Variable sub. It allows you better control.

Jai is right... it is basically a good way of naming your file or directory dynamically at runtime.

You should note though that as standard you can only take values from the target/inbound payload.

You cannot take values from the source

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

Hi! Nice info there!

But i'm wondering where i can find something about variables substitution using payload's attributes instead of elements.

Thanks in advance

Hi,

Could anyone tell me whether it is possible to specify some condition while using the values in the message payload for variable substitution?

Eg: var1 = Payload:<MT_name>,1,<field_name>,1

If Node 1 exists; then pick the value of <field1> from Node1; else pick <field1> from Node2

I just want to pick a file from a filesystem and write it to a filesystem. While writing I need the Filename to be of specific format. There is no message mapping in between; so I dont want to use a MM just for this condition.

Experts, Please help.....

Thank you
