 field-symbols: <lfs_ET_DATA> like line of ET_DATA.
 refresh ET_DATA.

 SELECT *
  FROM EPREI
  into CORRESPONDING FIELDS OF TABLE ET_DATA.

 loop at ET_DATA assigning <lfs_ET_DATA>.
   select *
 from EPREIH 
   into CORRESPONDING FIELDS OF TABLE ET_DATA-prices
   where PREIS = <lfs_ET_DATA>-PREIS
   and PREISTYP <= <lfs_ET_DATA>-PREISTYP.
 endloop.

it shows error:

"ET_DATA" is table without hedaer line and therefore have not component call prices.

How can i make this select correctly? Sorry for my english but i am so tired…

Answer 1

As the previous answer said, ET_DATA is a reference to a table type and does not have a work area.

So if you really want to add a list of EPREIH into ET_DATA-PRICE you have to point to the work area which is assigned to your field symbol.

Something like this:

 field-symbols: <lfs_ET_DATA> like line of ET_DATA.
 refresh ET_DATA.

 SELECT *
  FROM EPREI
  into CORRESPONDING FIELDS OF TABLE ET_DATA.

 loop at ET_DATA assigning <lfs_ET_DATA>.
   select *
 from EPREIH 
   into CORRESPONDING FIELDS OF TABLE <lfs_ET_DATA>-prices
   where PREIS = <lfs_ET_DATA>-PREIS
   and PREISTYP <= <lfs_ET_DATA>-PREISTYP.
 endloop.

extra tip: try using pretty printer with “keywords uppercase” and avoid “select *” if you are not using all fields from those tables.
