how do I modify date ranges

[jjay]

Hi Experts,

I have this scenario. We have a set of date ranges in the internal table like below here:

Date From Date To

a) 1.11.2002 31.10.2003

b) 1.11.2003 31.10.2004

c) 1.11.2004 31.10.2099

I want to modify record "(c)" by replacing the Date From with 1.11.2005. After doing this, the code should also update the previous record "(b)", Date To: 31.10.2005. How do I code this logic?Please advise

Move the from date to an variable and increase the date and also move the to date to another variable and increase

[ravi_teja10]

on change of date from.

w_index = sy-tabix - 1.

read table itab into wa2 index w_index.

wa2-date to = date from - 1.

modify itab from wa2.

endon.

hope this should work

You can try like this:

data: begin of itab occurs 0,
        from(8) type c,
        to(8) type c,
      end of itab.

data: a(4) type c.
data: b(4) type c.

itab-from = '01112002'.
itab-to = '31102003'.
append itab. clear itab.

loop at itab.
  a = itab-from+4(4).
  a = a + 1.
  concatenate itab-from+0(2) itab-from+2(2) a into itab-from.

  b = itab-to+4(4).
  b = b + 1.
  concatenate itab-to+0(2) itab-to+2(2) b into itab-to.

  write:/ itab-from, / itab-to.
endloop.
