You have two ways of addressing OTR alias texts directly in ABAP and using then in your development:
using method GET_OTR_TEXT of class CL_BSP_RUNTIME
For more information see the documentation on the interface for this class IF_BSP_RUNTIME.
using class CL_BSP_GET_TEXT_BY_ALIAS
Note that we are concerned with OTR alias texts here and not OTR long texts.
