function module

PERFORM select_frontend_file CHANGING p_file.

if u declare a function module like.. above , what is the meaning?

[Former Member]

This is not function module.

Your calling subrountine <b>select_frontend_file</b> passing P_file

[Former Member]

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

But this is not a function module.

hi

This is not FM.

It is calling Subroutine named <b>Select_frontend_file </b>

and passing the Parameter <b>p_file</b> thru Pass by Ref.

Hello,

Just to add to the above comments

<b>Perform select_frontend_file CHANGING p_file.</b>

will have a

<b>form select_frontend_file CHANGING X_file type XXXX.

endform..</b>

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
