[英]Changing IDoc segment SDATA via field-symbols?
My scenario is that I am getting an IDOC segment's data into a field symbol and change some fields based on some validations.我的情况是,我将 IDOC 段的数据放入字段符号中,并根据某些验证更改某些字段。
My code:我的代码:
READ TABLE idoc_data ASSIGNING FIELD-SYMBOL(<idocdata>) with key = 'E1EDK01'
IF sy-subrc = 0.
lcl_struc ?= cl_abap_typedescr=>describe_by_name( 'E1EDK01' ).
CREATE DATA dref TYPE HANDLE lcl_struc.
ASSIGN dref->* TO FIELD-SYMBOL(<sdata>).
IF <sdata> IS ASSIGNED.
<sdata> = <idocdata>-sdata.
....
<idocdata>-sdata = <sdata>.
ENDIF.
ENDIF.
Though the above snippet works fine, the continuity of field symbols is broken and now I have to pass back the changed data.虽然上面的代码片段工作正常,但字段符号的连续性被破坏了,现在我必须传回更改后的数据。 How do I use
ASSIGN
and let the field symbols take care of the changes rather than an explicit statement?如何使用
ASSIGN
并让字段符号处理更改而不是显式声明?
Something similar to below snippet though this won't work since <IDOC_DATA>-SDATA
and <SDATA>
aren't compatible.类似于下面的代码片段,尽管这不起作用,因为
<IDOC_DATA>-SDATA
和<SDATA>
不兼容。
READ TABLE idoc_data ASSIGNING FIELD-SYMBOL(<idocdata>) with key = 'E1EDK01'
IF sy-subrc = 0.
FIELD-SYMBOLS: <sdata> TYPE E1EDK01.
ASSIGN <idocdata>-sdata TO <sdata>.
....
ENDIF.
My expectation is that when I change the data in <SDATA>-FIELD1
, I want the changes to flow into <IDOCDATA>-SDATA
without using <idocdata>-sdata = <sdata>
.我的期望是,当我更改
<SDATA>-FIELD1
的数据时,我希望更改流入<IDOCDATA>-SDATA
而不使用<idocdata>-sdata = <sdata>
。
As @Sandra mentioned above, the incompatibility of field-symbols can be resolved by using CASTING
while assigning them.正如@Sandra 上面提到的,字段符号的不兼容可以通过在分配它们时使用
CASTING
来解决。 This would make the second snippet work.这将使第二个片段起作用。
...
IF sy-subrc = 0.
FIELD-SYMBOLS: <sdata> TYPE E1EDK01.
ASSIGN <idocdata>-sdata TO <sdata> CASTING.
...
ENDIF.
