Hi experts,
i solved the problem by myself.
some hints of solution:
2 internal tables of same type. itab1, itab2
loop at source_itab.
at new date.
l_invno1 = source_itab-invno.
endat.
at end of date.
l_invno2 = source_itab-invno.
if l_invno1 ne l_invno2.
concatenate l_invno1 l_invno2.
else.
concatenate invno1.
endif.
endat.
in itab1 , collect the data by date, but dont update invno.
in itab2, append date and invno.
endloop.
sort itab1 by date.
sort itab2 by date invno.
delete itab2 where invno eq space.
loop at itab1.
read itab2 with key date = itab1-date.
itab1-invno = itab2-invno.
modify itab1 transporting invno.
endloop.
very very sorry by putting this type of question in sdn.
regards
