Question: If I calculate a value in allocation methods within People Planning and I use that value in the plan table, is there an expression that can be used to grant that value?

When the plan is calculated it calculates the entire plan in cache and then writes it to the table.
To grant that value you would need to refer to the cached memory.
There are XFBR PLP parameter helper functions that have been provided to assist with this.
