Checking value in a structure

Former Member — Thu, 17 Jul 2008 06:13:42 GMT

I have a structure with 16 fields.

Only one of them contains a value while others are blank.

How do I check which field contains the value?

no shortcut . you have to chek all the fields. i faced the same issue. Only thin which you can do after geeting value in one field skip testing of rest of the fields.

Hi,

You can do it in 2 ways,

1. print them in report with WRITE statement and get it.

2. use condition STATEMENT with

IF (strname)-(Fieldname1) IS NOT INITIAL.

write: (strname)-(Fieldname1).

ELSEIF (strname)-(Fieldname2) IS NOT INITIAL.

write: (strname)-(Fieldname2). .

ENDIF.

Hi,

maybe this is helpful:


DATA gs_structure TYPE z_structure.

DATA gx_struc TYPE REF TO cl_abap_structdescr.
FIELD-SYMBOLS <gs_components> TYPE abap_compdescr.
FIELD-SYMBOLS <gv_field> TYPE ANY.

gx_struc ?= cl_abap_typedescr=>describe_by_data( gs_structure ).

LOOP AT gx_struc->components ASSIGNING <gs_components>.
  ASSIGN COMPONENT <gs_components>-name OF STRUCTURE gs_structure TO <gv_field>.
  CHECK NOT <gv_field> IS INITIAL.
* do something
  EXIT.
ENDLOOP.

How do I skip the testing the rest of the fields after the value is found in one field?

If I use EXIT satement, it comes out of the method while I need it to come out of the If condition only.
