Access using field symbols : Different data type

[Former Member]

Hi,

I am trying to access data from a cluster. The type of data being retrieved is different. Therefore i use a field symbol to create the type and then import the data. Now the data retrived has got different structures and sometimes they are even deep structures.

I want to access a particular value from all these different structures (Object_id). Sometimes it is just located at the firsty level

<Filed_symbol>->object_id.

Sometimes the data is available as <Field_symbol>->structure->Object_id.

How can i retrieve the data(Object_id) from such structures irrespective of the type of data being fetched from IMPORT.

Regards,

Rishav

Hi try this:

type-pools: abap.

data: r_struct type ref to cl_abap_structdescr.
data: it_components type abap_component_tab with header line.
data: component_addr type string.

field-symbols: <component> type any,   "component name i.e. OBJECT_ID
                     <component_adrr> type any.   "component absolute address i.e STRUCTURE-COMPONENT-OBJECT_ID

r_struct ?= cl_abap_typdescr=>DESCRIBE_BY_DATA( <field_symbol> ).  "get strcutre
it_components = r_struct->GET_COMPONENTS( ).       "get its components

loop at it_components.
   concatenate <field_symbol> it_components-name into component_addr   
                                                  separated by '-'.   "STRUCTURE-COMPONENT-OBJECT_ID
   assign component_addr to <component>. 
   <component> =  ...."give value here 
endloop.

The object type that you are importing is impotant to be known. Later you can import or export to the cluster
