¿Qué causa este problema?

You have tried to create a handling unit with the JIT customer's call
(components group). In at least one of the components groups selected,
there is already a reference to a HU.
The call has the following properties:
external call number : &V1&
JIT customer : &V2&
components group type : &V3&
&systemresponse&

El sistema emite un mensaje de error y no le permitirá continuar con esta transacción hasta que se resuelva el error.

&what_to_do&
It is not possible nor necessary to assign two HUs to a components
groups. Existing HUs (which are assigned to a components group) are
unpacked and deleted with action 'DEHU'
Note: the report 'RJITDELHU' deletes the HU references to a specified
internal components group number, without considering any other facts.
