Field access problem that is record specific
I have a field access problem that is record specific. This field is in a portal. For some records it works fine for data entry (drop down), or data display from the source, and propagation to other layouts. For other records, the field is not accessible at all, and data is not displayed from the source table. I have looked at the source data, and I see no difference between displaying and non-displaying data. Really need some help. Thanks.
