检查报告是否使用分层ALV [英] Check if Report uses hierarchical ALV or not
问题描述
我找到了一种导出分层ALV的方法，如下所示： ABAP：通过GUI报告有18列，通过RFC 6（分层ALV）
I found a way to export a hierarchical ALV like this: ABAP: Report via GUI has 18 columns, via RFC 6 (hierarchical ALV)
不幸的是，我不知道高级
Unfortunately I don't know in advanced if the report uses hierarchical ALV or not.
如果我对报告 RFSKPL00 应用以上答案的代码，那么我在 cl_salv_bs_runtime_info => get_data（）处得到一个异常：
If I apply the code of above answer to the report RFSKPL00, then I get an exception in cl_salv_bs_runtime_info=>get_data() here:
if t_data_line is requested.
import t_data_line to t_data_line from memory id cl_salv_bs_runtime_info=>c_memid_data_line.
if sy-subrc ne 0.
raise exception type cx_salv_bs_sc_runtime_info <=========
exporting
textid = 'ERROR'.
endif.
endif.
如何（通过abap代码）检查报表是否使用分层ALV？
How can I check (via abap code) if a report uses hierarchical ALV or not?
推荐答案
我想要相同的信息，而Sandra的回答并没有帮助我/我没有用，因为参数根本不起作用填。但是 cl_salv_bs_runtime_info 还有另一个函数可以解决我的问题， get_metadata 。它有一个参数 is_hierseq 可以按预期填充。
I wanted the same information and the answer by Sandra didn't help me/didn't work, because the parameters just wouldn't fill. But cl_salv_bs_runtime_info has another function that solved my problem, get_metadata. It has a parameter is_hierseq that gets filled as expected.
DATA: runtime_metadata TYPE cl_salv_bs_runtime_info=>s_type_metadata,
lr_data_descr TYPE REF TO cl_abap_datadescr,
lr_data_line_descr TYPE REF TO cl_abap_datadescr,
lr_data TYPE REF TO data,
lr_data_line TYPE REF TO data.
FIELD-SYMBOLS: <lt_data> TYPE ANY TABLE,
<lt_data_line> TYPE ANY TABLE.

" initialising runtime analysis
cl_salv_bs_runtime_info=>set( EXPORTING display = abap_false
metadata = abap_true
data = abap_true ).
***** Calling reports in different ways:
*** calling using SUBMIT:
* ALV grid output:
*SUBMIT bcalv_grid_07 AND RETURN.
* hierarchical output:
*SUBMIT SALV_DEMO_HIERSEQ_SIMPLE AND RETURN.
*** calling using CALL TRANSACTION:
* ALV grid / hierarchical output:
CALL TRANSACTION 'MB51'.
* Testing output mode using metadata
runtime_metadata = cl_salv_bs_runtime_info=>get_metadata( ).
IF runtime_metadata-is_hierseq IS INITIAL.
* ALV Grid / SALV
cl_salv_bs_runtime_info=>get_data_ref( IMPORTING
r_data_descr = lr_data_descr ).
CREATE DATA lr_data TYPE HANDLE lr_data_descr.
ASSIGN lr_data->* TO <lt_data>.
cl_salv_bs_runtime_info=>get_data( IMPORTING
t_data = <lt_data> ).
ELSE.
* hierarchical
cl_salv_bs_runtime_info=>get_data_ref(IMPORTING
r_data_descr = lr_data_descr
r_data_line_descr = lr_data_line_descr).
CREATE DATA lr_data TYPE HANDLE lr_data_descr.
CREATE DATA lr_data_line TYPE HANDLE lr_data_line_descr.
ASSIGN lr_data->* TO <lt_data>.
ASSIGN lr_data_line->* TO <lt_data_line>.
cl_salv_bs_runtime_info=>get_data( IMPORTING
t_data = <lt_data>
t_data_line = <lt_data_line> ).
ENDIF.
对于ALV / SALV， < lt_data_line> 。
In the case of an ALV/SALV, <lt_data> will contain the output, in the case of a hierarchical list it will be <lt_data_line> instead.
