Found the problem. It had to do with TIB_Connection settings.

From what I can deduce, If I set DefaultNoTrimming=True, the key fields
that include blank data( ' ' ) work correctly in linking Master and Details
via parameters, but then all the CHAR fields are padded with blanks (which
is not good). If I then set DefaultNoTrailing = True, this has no affect,
char(s) are still padded with blanks. (DefaultNoTrimming appears to trump
DefaultNoTrailing). Since I want DefaultNoTrailing to work I set
DefaultNoTrimming = False and looked for another solution, which I found.

I set FieldEntryTypes = DomainName

And then setup ColumnAttributes, I added DSection=YESTRAILING

When creating the database I used Domains to set up most of the basic data
types that are used throughout the schema.

DSection is a domain.

I really had to dig to find all this stuff, and still don't know the full
power of things like ColumnAttributes.

As an example where are the valid settings for ColumnAttributes defined?

Perhaps you could do a diff between the SQL trace monitor results for each
and spot a difference?
