This is another way of setting a dynamic file name at receiver. You can write a simple UDF to create the file name in the message mapping. File name created in the message mapping can be set at the receiver using adapter specific message attributes (ASMA).
In this example (iDoc to File scenario) I am setting the iDoc Message type and Material number to the file name in the below format.
File name: <Message Type>_<Material Number>_TimeStamp.XML
Create the UDF: Set_FileName
Configure the parameters of the UDF. In this example message type and material number
Write the UDF logic to set the file name
Configure the Message Mapping program
Configure the receiver file communication channel
You can set any text as the file name as it would be replaced by the ASMA.
Set the ASMA
Set the time stamp
