CL_SALV_BS_RUNTIME_INFO 通过 RFC 返回空引用 [英] CL_SALV_BS_RUNTIME_INFO returns empty reference via RFC

问题描述

这段代码几个月来一直运行良好:

This code has been working nicely for several months now:

SUBMIT (IV_REPORT_NAME)
   WITH SELECTION-TABLE selection_table
   USING SELECTION-SET IV_SELECTION_SET_VARIANT
AND RETURN.

DATA          lr_data_descr         TYPE REF TO cl_abap_datadescr.
DATA          lr_data_line_descr    TYPE REF TO cl_abap_datadescr.

cl_salv_bs_runtime_info=>get_data_ref( r_data_descr      = lr_data_descr
                                       r_data_line_descr = lr_data_line_descr ).

IF lr_data_descr IS NOT BOUND.
  ev_result_json = '[]'.
  EXIT.
ENDIF.

但在其中一种情况下，它通过 RFC 调用并抛出

But in one of the cases it is called through RFC and throws

lr_data_descr 未绑定

lr_data_descr is NOT BOUND

它通过 SE37 工作正常，但如果通过 RFC 执行会抛出错误，尽管我对 RFC 和 SE37 使用了相同的用户(类型服务")，相同的输入和相同的代码.

It works fine via SE37, but if executed via RFC throws the error despite I use the very same user (type "service") for RFC and SE37, same input and same code.

为什么会有不同?有没有办法得到一些错误信息?

Why is there a difference? Is there a way to get some error message?

如果我能找到它不受约束的原因，这真的很有帮助.我调试到 get_data_ref() 并发现此行的行为不同:

This would really help, if I could get the reason why it is not bound. I debugged into get_data_ref() and found out this line behaves different:

import t_component to lt_component from memory id
cl_salv_bs_runtime_info=>c_memid_data_def.
if sy-subrc eq 0.

如果我在se37中测试功能模块则sy-subrc为0，如果我用同一个用户进行外部调试则sy-subrc为4.

If I test the function module in se37 then sy-subrc is 0, and if I do external debugging with the same user then sy-subrc is 4.

这是一个临时报告，它的名字是AQZZZMM==========ZME80FN========

It is an adhoc report, its name is AQZZZMM=========ZME80FN=======

推荐答案

cl_salv_bs_runtime_info=>get_data_ref() 的 r_data_line_descr 未绑定的唯一情况是:

The only case where r_data_line_descr of cl_salv_bs_runtime_info=>get_data_ref() is not bound is:

• 未调用 ALV

对于SAPquery查询，它发生在没有提取数据时(在查询程序中，变量%runmode-show_on在没有数据时为空，ALV不显示，参见下面的截图).

With SAPquery queries, it happens when no data is extracted (in the query program, the variable %runmode-show_on is empty when there's no data, the ALV is not shown, cf screenshot below).

因此，您的问题可能是由于您的 pyRFC 程序传递的选择值与空无对应.当您从 SAP 调用查询时，这些值不同并返回一些数据(通过调试检查以验证哪些值不同).

So, your issue is probably due to selection values passed by your pyRFC program which correspond to nothing. When you call the query from SAP, these values are different and return some data (check it by debug to verify which values are different).
