ABAP and variable data definition

Former Member — Wed, 11 Jul 2007 10:34:22 GMT

May not make sense ... but I'm trying to write code like this

if X

field-symbols: <ls_screenline> type Z

endif

if Y

field-symbols: <ls_screenline> type Y

endif

So basically I can create a field-symbol <ls_screenline> that has a different structure depending on a condition.

Background: I'm in a BSP application that passes in a table structure of ANY type. This table has lines that are either structure Z or Y. Structure Z and Y mostly have the same structure and field names. In the code I'm writing I'm only accessing the fields that are common to Z and Y. So it seems silly to write my code twice, once for Z and once for Y.

Declare your field symbols as TYPE ANY and assign the value to it as per the condition.

FIELD-SYMBOLS: <fs_any> TYPE ANY.

if X 
assign z to <fs_any>. 
endif 
if Y 
assign y to <fs_any>.
endif

Hi,

Why dont you use the class CL_ABAP_TYPEDESCR and method DESCRIBE_BY_DATA to get the TYPE of the data that you receive.

Also if the fields that you want are anyway same you can use

ASSIGN COMPONENT comp_name OF STRUCTURE <> and deal with the fields you want to deal with.

With out knowing the datatype.

DATA: lr_rtti_struc TYPE REF TO cl_abap_structdescr.

lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data(<fs_data>).

Regards,

Sesh

assign component 'EXTERNAL_ID' of structure <ls_screenline_any> to <lv_cgpl_extid>.

Full code

CRMT_BSP_MKTPL_ TREE / BASIC DATA / BASIC_DATA_TPM

Data: lv_text1 type cgpl_text1.

field-symbols: <ls_screenLine_any> type any ,

<lv_cgpl_extid> type CGPL_EXTID,

<lv_cgpl_text1> type cgpl_text1.

if iv_screen_structure_name = 'CRMT_BSP_MKTPL_TREE' or

iv_screen_structure_name = 'CRMT_BSP_MKTPL_BASIC_DATA' OR

iv_screen_structure_name = 'CRMT_BSP_MKTPL_BASIC_DATA_TPM'.

assign et_screen_structure to <et_screen_structure>.

loop at <et_screen_structure> assigning <ls_screenline_any>.

assign component 'EXTERNAL_ID'

of structure <ls_screenline_any> to <lv_cgpl_extid>.

CALL FUNCTION 'Z_CRM_MKTPL_STOREREAD_MECHANIC'

EXPORTING

EXTID = <lv_cgpl_extid>

IMPORTING

TEXT1 = lv_text1.

if lv_text1 is not initial.

assign component 'TEXT1'

of structure <ls_screenline_any> to <lv_cgpl_text1>.

<lv_cgpl_text1> = lv_text1.

CLEAR: LV_TEXT1.

endif.

endloop.

endif.
