CR_PRO_TIME

Hi there

In the datasource 0MDG_ANLY_CR_DATASOURCE I find the field CR_PRO_TIME. The field is a decimal number but i am wondering if this is a decimal number showing days? ie. if 36 hours have passed it will show 2,5?

Furthermore is CR_PRO_TIME only updated when a request is approved/rejected etc or is updated at other intervals?

thanks in advance
