I would put the abandoned and normal Calls in 1 facts table (Calls) with the Concatenate(Table) statement. You can add a type "Normal" and "Abandoned" in order to use it later in a set analysis statement when needed.
The Skill number should be present in both tables in a correct manner...handle it in a proper way so they be exactly the same with commands like trim, num etc...
like define a variable: set vKey= num(trim($1) ) or maybe with Keepchar ($1,'0123456789').
Later use it in the load statement like: $(vKey(Skill_no)) as #Skill_Key
