在使用ABAP program調用function時trace mode指定為lean trace：

運行過程中的細節能夠被trace下來:

并且能夠在BRF+ workbench的trace view里瀏覽:

完整的report source code如下:

REPORT zcall_function. DATA: lo_function TYPE REF TO if_fdt_function,lo_context TYPE REF TO if_fdt_context,lo_result TYPE REF TO if_fdt_result,lx_fdt TYPE REF TO cx_fdt,lo_trace TYPE REF TO if_fdt_trace,lo_lean_trace TYPE REF TO if_fdt_lean_trace,lt_trace TYPE if_fdt_lean_trace=>ts_record,lv_string TYPE string.

總結

以上是生活随笔為你收集整理的在lean trace mode下运行function的全部內容，希望文章能夠幫你解決所遇到的問題。
