Hi,

The proper procedure is whatever inside your fm you need to raise the exceptions using RAISE <exception name>.

This <exception name> must be declared in exceptions tab of SE37.

Let us suppose you have declared 3 exceptions READ_ERROR, WRITE_ERROR, UNKNOWN_ERROR and raised them in your fm code.

Then the code that calls this fm will have:

Call function Z_ABC

Exporting:

Importing:

Exceptions:

Read_error = 1

write_error = 2

unknown_error = 3.

if you check the sy-subrc here if there is an exception inside the fm, then the value would be either 1, 2 or 3.

The number assignment will be done automatically in the cronological order in which the exceptions are defined.

The above is the recommended procedure.

Hope this helps..

Harikrishna.
