Please see Screenshot for error message.
I understand this error usually. But in this case I'm not sure. I'm basically trying to delete a record from table LKUP_UserAccounts where the PrimaryKey value is 9. The error says it conflicts with the "approvedBy_ID" column in the LKUP_UnitBaseConversions table. That tells me that at least one row in that table contains the value of 9 in the "approvedBy_ID" column. However, when I check the LKUP_UnitBaseConversions table....there are not rows where that value resides in that column. There are actually 3 different columns that could contains that value but in this case, 9 doesn't exist in any of the 3 columns.
What else could it be?
