UOM error in Cost Rollup

I get the following error in cost rollup.

Unit of measure conversion not found for Class:Count UOM:FT

I have looked for a mismatch from partmtl to part table and can’t find one. where else would the mismatch be? I also checked part table for one and couldn’t find it. Any Ideas are helpful.

Do you have UOM of FT in the Count UOM Class?

No

Try this thread. It helped me with a similar issue.

I already did that code below

    select * from PartMtl a
left join part b
on a.Company = b.Company
and a.PartNum  = b.PartNum
where a.UOMCode = 'ft' and ClassID ='count'
