Problem in CRMC_R3_ORG_GENERATE

Hi Team,

i have to move sales office from ecc to crm and i went t-code CRMC_R3_ORG_GENERATE and clicked on generated then it moved to bottom and its showing error.

screenshot attached.

i forgot to add my org unit when i am moving from R/3 Structure and moved default, due to that ierror is popping.

if i cant move back it to R/3 Strucure then whta action i have to take.

Thanks
