'Not released' Function module in EWM

Hi EWM Experts,

I am working in the EWM RF development. In EWM, most of the commonly used function module are with the status 'Not released'. As per best practice, it is not suggested to use 'Not released' function module'. Can anyone help whether can we use such FM or any alternative approach avaiable?

Find below list of FM's,

1. /SCWM/STOCK_PER_BIN_MON
2. /SCWM/TO_READ_WHO
3. /SCWM/TO_READ_SINGLE
4. /SCWM/MATERIAL_READ_SINGLE
5. /SCWM/HU_READ

Regards,

Neel
