Total Mass in on-screen BOM

Hello,

I am trying to get Pro/E WF2 to show me a summary of the total mass of all the parts in an assembly, and it is misbehaving.

I have set up a custom bom format file:

=======================================================

.breakdown

%$type %$name contains the following:

.titles Qty; Name; Material; Mass

---------------------------------------------------

.row %$quantity[-4d];%$name[-15.12s];%material[-10.7s];;%pro_mp_mass[-5.2f]

---------------------------------------------------

.summary

Listing of parts for assembly %$name:

.titles Qty; Name; Mass

---------------------------------------------------

.row %$quantity[-6d];%$name[-15.12s];%pro_mp_mass[-5.2f]

TOTAL MASS: $%[$total(pro_mp_mass)][-5.2f]

I have also set up a nested repeat region on a GA drawing, with a summation of the column containing the mass of everything in the outer (top level) region.

I have also set up my model tree to show a mass column.

Following regeneration:

The Model Tree reports the total mass as 3124kg

The Repeat Region reports the mass as 2719kg

The Custom BOM reports the mass as 3106kg

All three are working on the Master Rep

How is this possible?

The trouble is, I now do not know which to trust, if any.

My money tends to be on the model tree, but who knows?

I would welcome any constructive suggestions on how to make the three figures converge.

Regards,

John
