是否可以在使用 TABLES 参数的 RFC 并行处理期间更改 ITAB？
Is it possible to change ITAB during aRFC parallel processing using TABLES parameter?
我目前正在为大规模 GI 作业设计并行处理（通过使用 aRFC）。
问题是 - 我怎样才能得到每个工作结果的 return？
我使用了在主报告 (gt_result) 中声明的 TABLES 参数，并且当 aRFC 完成时，每个 FM 在函数内部执行 MODIFY itab。
问题是 - 在每个作业中，我检查了数据是否已更改（在 gt_result 中），但是当作业完成并且 return 到主报告程序时，ITAB 没有更改!
是否可以使用RFC 并行处理更改ITAB 值？还是从每项工作中获得结果的其他方式？
如有任何帮助，我们将不胜感激。谢谢！

The RECEIVE RESULTS FROM FUNCTION instruction 要求您说明您希望接收哪些参数以及希望将结果存储在何处。不幸的是，所有参数都是可选的，那些你没有明确提及的参数只会被丢弃。所以用 no 参数调用它（就像你在这里做的那样）是没有意义的，但仍然合法。
您可能将传递给 aRFC 调用的 table 声明为全局变量（不要那样做！），然后在您的 FORM return_z_pp_para_test 中再次访问该全局变量 table 尚未更改。
为了接收函数调用的实际结果，请执行以下操作：
DATA: lt_results_target TYPE STANDARD TABLE OF gs_target,
