HI,

You can use Field Symbols for working with internal tables. It is a good practice to use field symbols.

These are the links about general theory behind field symbols, data references and for using field symbols for internal table operations::

Hope this will solve your problem.

Hi,

Field symbols are nothing but dynamic memory allocations. so we need to assign field symbols. If we are using field symbols which are not assigned then program will go to dump. we should be very careful while using field symbols. Please go through the following code which will help you in understanding about field symbols

if <fs> is assigned.

unassign <fs>.

endif.

loop at it_marc assigning <fs>.

check <fs> is assigned.

move <fs> to wa_marc.

append wa_marc to it_marc.

clear wa_marc.

endloop.

Hi,

Field symbols are something like pointers which point to the contents of the field/internal table.

Syntax to declare:

FIELD-SYMBOLS <FS> type STRUCTURE .

Assigning field symbol to some field:

ASSIGN var1 TO <fs>.

Changes to field symbol will affect the contents of the field/internal table directly.

For further info:

You can find the examples on field symbols in TCODE: ABAPDOCU.

under the ABAP Programming Lanuage->Basic Statements.
