使用field-symbols提高访问内表的效率

tables : pernr .nodes : peras.infotypes : 0000,            0001,            0002.field-symbols : <fs_p0001> type p0001.get peras.  loop at p0001 ASSIGNING <fs_p0001>.    write : / <fs_p0001>-pernr.  endloop.

注：该程序的属性中要设置逻辑数据库为PNPCE

 

Field symbols can be used as placeholders for variables . They are useful in dynamic programming and for speeding up the processing of internal tables.

Field symbols可以被用作变量的占位符（替代品）。它们在动态编程和提高对内表的处理速度方面很有作用。
