Various checks are carried out when reading a new routing or BOM in a single order.
If one of the following questions is answered with yes then a new routing cannot be read in:
Is the order partially or finally confirmed?
Is the order partially or completely delivered?
Do purchase orders for externally processed operations already exist?
Are there inspection lots for the order?
Are there future change records from the confirmation (parallelization)?
If one of the following questions is answered with yes then a new BOM cannot be read in:
Do purchase orders already exist for non-stock components or components with direct procurement?
Have components already been taken from stock?
Are there transport requirements?
Are there future change records from the confirmation (parallelization)?
Are there goods movements containing errors that have not been processed?
