Generic type in perform

Former Member — Thu, 30 Nov 2006 18:24:42 GMT

I have 3 different types of ranges in a program, and i want to create a perform for append 1 in all of them, when i make the declarations i don´t put the type of the range, so i can pass it, but i can´t use the fields of the table.

is there any way of doing it?

Thanks in advance

Example simple:

ranges day for sy-datum.

ranges money for bseg-waers.

ranges price for bseg-kbetr.

perform ap1 tables day.

form ap1 tables tab1.

tab1-low = 1.

append tab1.

endform.

ranges price for bseg-kbetr.

perform ap1 tables day.

perform ap1 tables money.

perform ap1 tables price.

form ap1 tables tab1.

loop at tab1.

tab2-low = tab1-value.

append tab2.

endloop.

endform.

It gives me a sintax error, because it says that the tab1 has no estructure, so i can´t call value

Hi try this:

form xxx tables tab.

field-symbols: <fs_line>,

<fs_field>.

data: v_line type ref to data.

create data v_line like line of tab.

assign v_line->* to <fs_line>.

assign component 'LOW' of structure <fs_line> to <fs_field>.

if sy-subrc eq 0.

<fs_field> = '1'.

append v_line->* to tab.

endif.

endform.

The reason is <b> STRUCTURE < STRUCTURE ></b> is missing.

perform ap1 tables day.

form ap1 tables tab1 <b>STRUCTURE < STRUCTURE >.</b>

tab1-low = 1.

append tab1.

endform.

whenever the internal table is passed the structure must be specified in the FORM section.

I think that it is a good idea to use field-symbols, but it gives me a syntax error, in

"append v_line->* to tab."

but i think that probably i will be able to use it for append and for read.

Thanks in advance

It has to be: append <fs_line> to tab.

Anyway you can use only the field-symbols:

ranges day for sy-datum.
ranges money for bseg-waers.
ranges price for bseg-kbetr.

perform fill_range using: 'DAY',
                                   'MONEY',
                                   PRICE'.

FORM FILL_RANGE USING RANGE.
   DATA: RANGE_TAB(15) VALUE '&[]'.
   FIELD-SYMBOLS: <TRANGE> TYPE TABLE,
                               <W_RANGE> TYPE ANY, 
                               <VALUE>       TYPE ANY.


   REPLACE '&' WITH RANGE INTO RANGE_TAB.

   ASSIGN (RANGE_TAB) TO <TRANGE>.
   ASSIGN (RANGE)         TO <W_RANGE>.

   <W_RANGE>(3) = 'IEQ'.

   ASSIGN COMPONENT 'LOW' OF STRUCTURE <W_RANGE> TO <VALUE>.
  <VALUE> = '1'.
  APPEND <VALUE> TO <TRANGE>.

ENDFORM.
