hola buen día.

el problema es que al querer hacer la reorganización en las tablas de la base de datos. te dice que el atributo esta establecido para que no acepte nulos. y es necesario que establezcas un valor inicial.

Caso 1:
Si es un atributo (llave foranea) hay 2 cosas.

1- hay una columna en la transaccion " NULLABLE" , solo cambiala a YES. para que acepte nulos.

2-Si no quieres que acepte nulos. en la propiedades del atributo de la llave foranea , busca la propiedad "Initial value" y coloca un numero, con cual se inicialice los campos.

Nota: Este VALOR tiene que existir en la base de datos como llave primaria.

Saludos
