I set the calculated field in the workflow, where the A field is the parameter {P0} needs to be calculated B=A*2.1
I use the formula {multiply({P0};2.1)} and {multiply(P0;2.1)}
The operating condition is selected as: when saving
The scope of operation is: all records
But in the end, after I entered the A field, there was no change in the B field and I asked for help.
The A field is an integer type and the B field is a floating point type.
