Hello. I had the same problem that I could finally solve. Main table index was set to large number. I changed it to number and it worked. All relationships were okay, I made a query to check and got the data as it should be. I hope it can help.

But old system can not handle the large number so if you can't convert it to number you should change the format into short text in two tables ! This way problem will resolve!

2024-07-21T13:13:04.5066667+00:00 What are the data types of the Iqama columns in the two tables? From your screenshot, that in Employees is clearly a number, which I assume to be the identification number of the residence permit. Normally a long integer number (as set in the column's Field Size property in table design view) would be used in the case of a key like this. The data type must be the same in both tables.
Note that in a one-to-one relationship type like this one of the tables, almost certainly Employees in your case, must be the referenced table in the relationship.
What happens if you join the tables on the Iqama columns in a query?
