Hello
I´ve had this table u_parts
class|model|W20-13|w20-14|w20-15|
xrt |Model1|x |null | null
xrt |Model2|null | x | null
xrt |Model3|null |null | x
xrt |Model4|x |null | null
and convert it to this
class|model|type
xrt |Model1|w20-13
xrt |Model2|w20-14
xrt |Model3|w20-15
xrt |Model4|w20-13

You've been here long enough to know this...

As Phil noted, I can't actually test the code, since you didn't provide any directly usable data:
SELECT up.class, up.model, ca1.type
FROM dbo.u_parts up
CROSS APPLY ( VALUES([W20-13]),([W20-14]),([WorkLog]) ) AS ca1(type)
WHERE ca1.type IS NOT NULL
