Failure in creating a dynamic structure

Former Member — Mon, 09 May 2011 14:49:49 GMT

Hi Guys,

i get a strange failure while creating a structure from components.

lr_out_tab ?= cl_abap_tabledescr=>describe_by_data( it_outtab ).

lr_out_struc ?= lr_out_tab->get_table_line_type( ).

lt_out_comp = lr_out_struc->get_components( ).

lr_new_struc = cl_abap_structdescr=>create( lt_out_comp ). <-- cx_sy_struct_comp_name exception

I get this failure, when i have component-names like xxx-yyyy. Does somebody have an idea how to slove this.

Greetings

André

Hello Andre,

You're getting the error message because the param P_STRICT of the method CREATE( ) is set to TRUE(by default).

If you set the creation mode as "strict"(P_STRICT = CL_ABAP_STRUCTDESCR=>TRUE), no special characters are allowed in the column names! Since your component names contain a '-' you're getting the exception CX_SY_STRUCT_COMP_NAME.

If you set the creation mode as "non-strict"(P_STRICT = CL_ABAP_STRUCTDESCR=>FALSE), following spl. characters are allowed:

#$%&*-/;<=>?@^{ | }

So in your call you need to set the "non-strict" mode while creating the dynamic structure:

*   Get the Dynamic structure definition
    TRY.
        lo_structdescr =
          cl_abap_structdescr=>create(
              p_components = lt_struc_comp
              p_strict     = cl_abap_structdescr=>false ).
      CATCH cx_sy_struct_creation .                     "#EC NO_HANDLER
    ENDTRY.

Hope i'm clear.

BR,

Suhas
