In this menu option, you can define your own requirements for packing delivery items. Requirements are represented as form routines which constitute shorter subprograms and check different criteria during packing. If you define new requirements for packing handling units, you must activate the new requirements before using them, otherwise they will not be taken into account.
A requirement for packing handling units can, for example, stipulate that packing is not possible if a credit block exists.
For further information on creating requirements, refer to the Implementation Guide in the section "Routines".
