A routing operation has an invalid sequence or work center
Check sequence numbers within each routing and confirm that the selected group is a manufacturing work center.
Choose the message that matches your import.
A sequence repeats within one routing
Message may mention: sequence number.
What it means
Two steps share a sequence within one routing.
Import context: Manufacturing routings.
Check this first
Check both the sequence values and which routing owns each row.
Show the steps
Check how the detail rows are linked
- Confirm whether this is a single-file or multiple-file import.
- Identify the parent record key and the key used to connect each detail file.
- Verify that every required detail row points to an intended parent, with no spelling or whitespace changes in the linking value.
- Check the import's field mapping for the detail sublist. Defaults alone do not establish that detail rows were imported.
- Separate a record identifier from a line identifier. They serve different purposes.
For assemblies, link member rows to the assembly. For routings, check the operation sequence within each routing. For customer/contact combinations, keep each record's identity and fields separate. Check the actual mapping fields for the record being imported.
If that looks right
A sequence can be reused in a different routing. Check for repetition within the same routing, not across the whole file.

The group is not a manufacturing work center
Message may mention: manufacturingworkcenter.
What it means
The selected group may not be designated as a manufacturing work center.
Import context: Manufacturing routings.
Check this first
Check the group record, not just its name.
Show the steps
Check the record reference
- Find the field named in the error on the import's Field Mapping page.
- Open its edit control and check the selected reference type.
- Compare that setting with the actual CSV value. A number could be a name, an external ID, or an internal ID. Its appearance alone does not establish the type.
- Locate the intended record in the same account. Confirm its identity and whether it is available for this transaction.
- Correct the file or mapping so they agree. Use a default only when it applies to every affected row.
If you need to see internal IDs, enable them in your personal preferences or include them in a saved-search export. Supported reference types vary by field. Name matching is generally case-insensitive, so changing capitalization alone should not be the standard recommendation.
For a duplicate-record message, determine whether you intend to update the existing record or create a different one. Do not generate new external IDs simply to get past the error. For inactive records or subsidiary restrictions, verify the intended business setup before changing it. Those are account decisions, not text-cleanup operations.
