You can write a function module inside this using the paramter p_file.

But this is not a function module.

This is not FM.

It is calling Subroutine named Select_frontend_file

and passing the Parameter p_file thru Pass by Ref.

Hello,

Just to add to the above comments

Perform select_frontend_file CHANGING p_file.

will have a

form select_frontend_file CHANGING X_file type XXXX.

endform..

the purpose of this perform is to do some operation on data in P_file

so in the form select_frontend_file we will be performing some validations or operations on the data passed through p_file to x_file and changing it's contents

in the form "select_frontend_file" the x_file should be recieved as the same type shown as XXXX of p_file

Reward if helpful

regards
