For all entries Where condition character length partilally has to be used

Question

Hi,
I need to fetch all the data reocrds of one internal table into the other with the condition that in one of the field of first internal table only partial length of the character has to be used as a where condition.
Example:
Select xxxx
          yyyyy
          zzzzz
into it_tab2
for all entries in itab1
where field2 = itab1-field1(4).
where field1 of itab1 has length of 8 and field2 belongs to itab2.
As it throws the error msg :
it will ignore the length restriction mentioned in where condition of the for all entries

Answer 1

Hi.
If you are trying to fetch from any database table based on your modified table use this logic.
Dfine another internal table same as itab1, with field one lenght as 4 char.
ex:
data: begin of it_tab2.
        field1(4),
end of it_tab2.
loop at it_tab1.
it_tab2 = itab1+0(4).
append it_tab2.
clear it_tab2.
endloop.
now you can fetch from database table....using it_tab2.
Select xxxx
yyyyy
zzzzz
into it_tab3
for all entries in itab2
where field2 = itab2-field1(4).
If you only want to move the entries form one internal table to another internal table and truncate the field1 of itab1.
then no need to use any for all entries...
apply this logic
data: begin of it_tab2.
        field1(4),
end of it_tab2.
loop at it_tab1.
it_tab2 = itab1+0(4).
append it_tab2.
clear it_tab2.
endloop.
