In support for S/4 Hana project conversion, business asked us to update level 2 WBS for account assignment to be unchecked. But there level 3 WBS assigned to level 2, where postings exist. Tried CNMASS t-code but it is error out as the change can only made through batch input or substitution.
Any help, if we even can update the level 2 WBS when postings are there on level3?
Thank you
