BAPI_ALM_CONF_CREATE not generating Actual Costs in PM Order

Hello experts.

I'm using BAPI_ALM_CONF_CREATE to do the confirmation of hours in a PM order. But when I check the order, the real costs are not calculated.

If I post confirmation using IW41, it works normally.

These are the parameters that I'm using:

CONF_NO 0000000000

ORDERID 001004630790

OPERATION 0010

FIN_CONF X

COMPLETE X

POSTG_DATE 20190725

PLANT DA02

WORK_CNTR ST051301

ACT_WORK 8.0

REM_WORK 0.0

ACTUAL_DUR 0.0

EXEC_START_DATE 20190725

EXEC_START_TIME 101000

EXEC_FIN_DATE 20190725

EXEC_FIN_TIME 141000

ACT_TYPE TECMON

ACT_WORK_2 0.00

REM_WORK_2 0.00
