CJ20N : Issue in deriving Network Number

Hi,

For T-Code CJ20N while creation of Network Number I am able to create custom Network Numbers using BADI WORKORDER_UPDATE Method IF_EX_WORKORDER_UPDATE~NUMBER_SWITCH.

When I am trying to settle the Networks its giving dump

" No Status object is available for <NTW number> "  (BS-001) - I think OBJNR is not getting updated in JEST, JSTo and ONR00 tables

Kindly check and let me know if there is any other way to create Network Numbers successfully. (Exit CNEX0012 is not getting triggered)
