What does it do? Calling or Registering
Subroutines .
Subroutines can be called statically and dynamically, internally and externally. Parameters can only be passed if they are called statically. Also, subroutines can be registered for execution at the end of an SAP LUW .
ABAP_PGL No implementations in function modules and subroutines
Latest notes: Subroutines are obsolete. Do not create new subroutines in new programs. Subroutines created in existing programs for internal modularization can continue to be called. Whenever possible, avoid calling subroutines of other programs externally.
