Transportation Management with SAP LES

Packing
The requirements are identified by a three-digit numerical requirements key. Your own
requirements should be in the number range between 900 and 999 and not between
610 and 699, as stated in the SAP documentation. In Customizing, you can see that the
subsequent function and the copying control group indicator (not shown on the maintenance
screen) are already predefined (see Figure 8.2).
Figure 8.2 Creating Your Own Requirements for Packing
When you select
, an overview appears with all of the requirements
and routines created. Enter your requirements key in the next available line. The
system branches automatically to the ABAP/4 editor. Program your requirement. (I
will not, however, go into further details at this point on ABAP/4 programming.)
For control purposes, you can also click from the overview screen to display the
corresponding coding for the requirement.
Requirements are user exits and are programmed in ABAP/4. You can also set up
requirements of your own using Transaction VOFM or via the Customizing menu
by choosing Logistics Execution • Shipping • System Modifications • Routines
• Define Copying Requirements. When you access this function, the screen is
initially blank. Therefore, select Requirements • Subsequent functions • Packing
from the menu.
Listing 8.1 displays sample coding from requirement 112 predefined by the SAP
system.
