Manufacturing costing report (MFGCOST) not showing actual and expected values in operations

SUGGESTED

Hi all,

Our client uses the Calculate Expected cost function (Manufacturing)

That prints the Expected cost type report without the actual and expected costs for these workcenters. I've attached reports how it is blank in the first image. However a few months back that section had values (second image)

 (not appearing)

 (appeared few months back)

Can anyone clarify why this data isn't appearing in the excpected cost type of MFGCOST report when it previously did. Maybe it's a change made in the system?

TIA
