Read from a internal table whose name is decided in runtime

[Former Member]

Dear ABAPers

I've an internal table's name in a variable, the name is populated in runtime (user_command->ls_selfield-tabname). Now that using the name (in the variable) i need to read a row from that particular internal table (which is populated into the variable). How can i do that.

Hi,

Use below:

DATA: tabname(40) TYPE c.

WRITE ls_selfield-tabname TO tabname.


FIELD-SYMBOLS: <fs> TYPE table, 
               <fs_wa>.

ASSIGN (tabname) TO <fs>.
READ TABLE <fs> ASSIGNING <fs_wa> INDEX 1.

Use field symbols.

FIELD-SYMBOLS: <FS> TYPE ANY table.

loop at (tab-name) assigning <FS>
