I'm using VFP 7.0

When I try to build RI, I get this error:
"Cannot find object DD_CHIEXPR in the database"
Program: dbc_aftermodifytable
Line:(35)lc = DBGETPROP(cTableName+'.'+FIELD(ln),"FIELD","RULEEXPRESSION")

I don't have a clue what "DD_CHIEXPR" is.

I have dbc_AfterModifyTable() automatically updating my Validation class, and it works fine. I only get this error when I'm trying to build the RI.

Is there some way to tell dbc_AfterModifyClass that the RI builder is executing and not execute? ie: "If !"
Or determine what "DD_CHIEXPR" is?

TIA
