I have activated FM integration with Cost Center, Than I make maintenance order type PM01, I assign equipment with cost center 4100, I also make settl rule to cost center 4100.

When I want to make confirmation or settlement, there is meesage error as below:

<i>Error accessing function module: FM_FIPOS_GET_FROM_FIPEX parameter: I_FIPEX T_FMFXPO
