[Former Member]

hi,

I try to change hierachie for the released WBS with function CN2W_WBS_HIERARCHI_CHANGE_STRU, but I got an error like : "Hierarchy could not be included; root element does not exist" But this does not happen when we change the WBS hierachie in CJ20N, Could you please help me how to change hierachie for the released WBS using the function ? And Which function I can use ?

Thanks in advance

you are using correct function module. Just check the values in Up and down columns .
