IF_HRTNM_TN_ASSIGN_ALV SAP Interface - Interface for ALV TN assignment







IF_HRTNM_TN_ASSIGN_ALV is a standard SAP interface, see below for any documentation including details of methods, attributes, events etc. Interfaces are defined much the same as a class using the same transactions but act a bit like a template (in none OO terms).

This provides a mechanism for unrelated objects to use a set of common behaviours and functionality.
