Simple Addition and Subtraction
Hi There, I am having trouble in returning correct values with a simple addition and
subtraction beast mode. It appears that any column with a blank value will not return a end value. And any row with values in all columns calculates properly. Any suggestions on how to calculate to consider blank values as zero value? Thanks
Beast mode calculation formula:
End Future Stock Balance:
`Total Stock`+`Total QTY to be delivered``Total fcst QTY``Total Reqmt QTY`

@Emma the IFNULL function is also useful for this and does the same thing. COALESCE is useful when you need to evaluate multiple fields before replacing with a single value. Here is what yours would look like with the IFNULL function:
IFNULL(`Total Stock`,0)+IFNULL(`Total QTY to be delivered`,0)IFNULL(`Total fcst QTY`,0)IFNULL(`Total Reqmt QTY`,0)

Hi @Emma
You can use the COALESCE function to default a null value to a specific value. It does this by selecting the first nonnull value in the list of parameters given
COALESCE(`Total Stock`,0)+COALESCE(`Total QTY to be delivered`,0)COALESCE(`Total fcst QTY`,0)COALESCE(`Total Reqmt QTY`,0)
If you use simple arithmetic operators (+, , *, /) with a null the end result is null because it doesn't know how to handle nulls.
