Re: Extension .txt.pgp to target file in receiver file communication channel

I don't think SAP's adapter necessarily have the same features as Advantco's!

Refer the documentation for SAP's adapter - it only allows variable substitution for elements in payload (payload:xxx) or attributes in message header (message:xxx)

Defining Variable Substitution for Target Directory/File Name - Advanced Adapter Engine - SAP Library

Sumeet, best bet is to go for Praveen's suggestions since you are using SAP's standard adapter.
