Bring previous day value as starting point for next day in a measure within Power BI

I have been trying for a few days to do this with no avail and its probably something simple.

enter image description here

I am trying to calculate the PRED_BL column which is based on PRED_WORKLOAD + PRED_REC - WORKDONE

As you can see I can do the first day because I have the PRED_WORKLOAD volume for the 04/10/2021, but PRED_WORKLOAD future dates are blank - what I need to do is bring the 314419 from the 4ths PRED_BL column as the PRED_WORKLOAD value for the 5th October, to start the calculation but also make sure the calculated PRED_BL's are used as the starting points for each of the future dates.

This is probably something simple but for a Power BI newbie like me not so.

Hope someone can help me, thanks in advance

As in this similar post, you can't recursively define columns based on previous ones but you can compute cumulative totals instead to a similar effect.

It would look something like this:

PRED_BL =
SUMX (
    FILTER ( Table1[DATE], Table1[DATE] <= MAX ( Table1[DATE] ) ),
    Table1[PRED_WORKLOAD] + Table1[PRED_REC] - Table1[WORKDONE]
)
