Create empty file with same name to send to receiver for each file from sender

[Tyler_Tondevold]

Using BTP CI, I want to generate an empty file for each file picked up from the SFTP sender and sent to the receiver. These files will need to be sent to the receiver as well. These files will have the same name as the original file with a prefix of "CHK_". How can this be accomplished?

You can take inspiration from the below design. 

Steps
1 - Standard SAP Message Header - "CamelFileName" is set by sender SFTP adapter which contains the source filename.
2 - Use a Sequential Multicast.
2a - 1st Branch - Write the target actual file to receiver with mapping if required. 
2b - 2nd Branch - Use this to write the Flag(Empty) file. Use a content modifier and set the body blank and overwrite message Header "CamelFileName" with an expression value - CHK_${header.CamelFileName} as below

3 - Target SFTP Receiver Adapter must not have anything update in Filename section as target filename would be dynamically derived from header - "CamelFileName".
