yeah.
You have BeneficaryHistory linked to the Beneficiary table.
Beneficiary has a ID field - but not a (unique) description field. And importantly no (single component) description field key.
So, the wizard has been a little too clever, and not clever enough. UpdateBeneficiaryHistory procedure, BENH:BeneficiaryID field, Lookup Settings - "use Description instead of value" is on - and it should be off. You can obviously change that in the app.
