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?
