READ TABLE ...

Former Member — Mon, 03 Nov 2008 15:47:01 GMT

Hi there. How can I assign an itab to pointer to have possibility to make operations on pointer (not itab)?

[ I ]


DATA: itab LIKE dbtab OCCURS 0 .
field-symbols: <ritab> type any table .
field-symbols: <rline> type any .

ASSIGN itab TO <ritab> .

it's ok but now ... when I want to ...


READ TABLE <ritab> INTO <rline> INDEX G_arow .

... I receive You cannot use explicit or implicit index operations on tables with

types "HASHED TABLE" or "ANY TABLE". "<RITAB>" has the type "ANY TABLE".

[ II ]


DATA: itab LIKE dbtab OCCURS 0 .
field-symbols: <pointer> type standard table .
field-symbols: <rline> type any .

ASSIGN (itab) TO <pointer> .

the ASSIGN statement returns sy-subrc = 4

READ TABLE <ritab> ASSIGNING <rline> INDEX G_arow .

there's a mistake in my post but I can't edit it now...

Explanation: <ritab> = <pointer>

Also remove the brackets from the itab ...

ASSIGN (itab) TO <pointer> .

isntead to ASSIGN itab TO <pointer> .

Hi,

change your declaration of

field-symbols: <pointer> type any table .

field-symbols: <pointer> type standard table .

INDEX TABLE would be better.

Explanation. something defined with reference to ANY TABLE could be a HASHED table, and that doesn't support indexed operations. SORTED tables and STANDARD tables do. They are referred to generically as INDEX.

DATA: itab LIKE zlhist02 OCCURS 0 WITH HEADER LINE .

field-symbols: <pointer> type table .
" OR
field-symbols: <pointer> type standard table .
" OR
field-symbols: <pointer> type any table .

field-symbols: <line> type any .



ASSIGN itab TO <pointer> . " ERROR



READ TABLE <pointer> ASSIGNING <line> INDEX 1 .

"itab" is not type-compatible with field symbol "<POINTER>".

If you hadn't defined ITAB as a table with a header-line, you wouldn't have had the problem.

ASSIGN itab[] TO <pointer> .

Tables with header lines are inherently ambigous - as you've found. Is itab the table or the header-line? In this case, it was the header. Don't use them - they're not allowed in an Object Oriented context anyway. Instead define seperate work areas.

Defin your table with the types as you have defined your field symbols POINTER with types.


DATA: itab Type standarad table of zlhist02.

The problem is that original itab declaration is more complex ...


DATA: BEGIN OFitab OCCURS 0 ...
 ...  field1 ...
 ...  field2 ...
 ...  field3 ...
 ...  ...... ...
 ...  END OF itab .

and I can't change it

OK - in that case change the code as I suggested.
