Sorry… it’s done, but I don’t think by the best way:
[list:f92141b2e7]1. Actually, I’ve created a schema with only one attribute field.
2. Then I’ve created a map between the incoming message and the previous schema.
3. Then I use a transform shape.
4. Finally, in a new send pipeline, I have linked the schema with a flat file assembler shape.[/list:u:f92141b2e7]
It may be possible to do this more easily… [size=9:f92141b2e7]but it doesn’t matter ’cause it works ![/size:f92141b2e7]
