Hi Gurus,

Please assistance me.
When I make a WBS colony regularisation utilizing BAPI K_SRULE_SAVE_UTASK it is created correctly successful COBRA and COBRB tables. however, erstwhile I verify the colony regularisation successful transaction CJ20N successful update mode it is duplicated successful each disposable lines. When I participate cj20n successful presumption mode I spot it correctly.
