Error while estimating the production order


I’ve created the production order for a CW item and the formula contains a CW item line

While estimating the production order the system gives the below error:

Item number: ABCDEF-12

Automatic production creation

Illegal splitting

Update has been canceled.

Appreciate help on the matter.

It sounds like you have a customization in there, I would advise a developer debug it and tell you the cause.
