Link reference greyed out

Oct 10, 2023 01:49 PM (801 views)

I set a column with Link ID on one table and tried to use that as a reference in another table, but the option is greyed out for me.

The column in the reference table has unique values. The only difference was that the datatype of the column in the main table was continuous, but I change it to nominal to match the reference table.

Any insight as to what I might be doing wrong?

 

Thank You

Sometimes the key is making sure that both tables are saved to disk. If they aren't, JMP doesn't know how to reference the tables properly.

I ran into a similar issue and the save mentioned by Jed works most of the time.  I found an exception when writing a JSL Script to link multiple tables together.  Extra complication is this action took place in a loop to implement action on multiple tables.   In this case when main table was saved, I would lose one or both of the tables.  My work around was to merge the link table information into the main table and then save.  Links are eliminated, information is available for analysis.
