Purpose
Demo ZCL_XTT_DEMO_120 passes an object directly to MERGE( ). Use this approach when a class already exposes the fields and tables required by the report and a duplicate root structure would add no value.
Merge an object
Pass the object reference to MERGE( ); public attributes are resolved like structure components.
Example: personnel actions
The pattern is especially useful for an existing domain object, for example a class that already contains IT 0000 and IT 0001 data for a personnel action.
The template can:
- read scalar and nested attributes such as
{R-MV_MASSN}and{R-MS_P0000-STAT2}; - repeat an internal table such as
{R-MT_P0000}; - read an entry with an expression such as
{R;cond=value-MT_P0001[ 1 ]-ENAME}; - derive conditional text through
;cond=.
No additional root structure is required.
Attribute visibility
Public attributes are always available.
To expose protected or private attributes, declare ZCL_XTT_REPLACE_BLOCK as a friend of the report object. Do this deliberately: it gives the rendering layer access to the object’s internal state.
