Now I have a problem,
I need to add a new period in Contract(ME33K),
I already have a period item in contract like 01/01/2011~12/31/9999, 100,100.
I need to use LSMW,
1.change the period to 01/01/2011~01/01/2012,100,100
2.add a new period :01/02/2012~12/31/9999,100,105
I can do the first step beacuse there has value in table A016/KONP,but I can't do the second step,the field KNUMH is autocreated by system? I use BUS2014/PURCONTRACT_CHANGE
