Wip accounting class code inactive

hi,

i have mulltiple WIP set for my asset, as i have multiple cost center which reflects different accounts. When i run corrective maintenance i have no issue automatically my correct wip is selected based on what i have defined in  my asset number screen.

my question to you is when i select maintenance work bench for forcasting my preventive maintenance, an error pops up(check attachment) wip accounting class code is inactive. how can i deal with this issue?

also i would like to add that the default wip accounting class is disabled, the reason for this is like i have mentioned above i have multiple (36 different types) WIP for my asset. the default wip is linked with incorrect account segments. So i can't use the default WIP in any case.
