Locked PO Release Lines

We are on Day 8 post Go Live on 6.1 and things are bumpy, but
getting much better. In regards to locking PO release lines, where
is that data stored? There is a field called LockRel on the PORel
table, but when I include this on the PO tracker subform, it is
blank. The data dictionary shows this as an 8 character text field,
but on the release screen, it looks like a logical field. When I
look at the table through ODBC, the LockRel field is empty for the
record in question, but MRP responded correctly and didn't make any
change suggestions.

Also interesting is the fact that the data dictionary mentions a "B"
for Buyer locked, "V" for Vendor and "BV" for both. This noted is
dated 2002. Does this work differently in the previous version? I
see no way of indicating this in 6.1.

Any ideas as to where the data is stored?
