There are a few possible causes for this message:
1. One possible reason is that there may be multiple configuration items in the CMDB that have the same name. It's necessary to include other attributes in the load file to provide a unique value for the configuration item. For example, the load may be formatted as:
Including "dependent_serial_number" helps to provide a difference between two configuration items that both have the name name.
2. When embedded relationships are used in the spreadsheet, user should make sure that the CI has only "name" as the identifying attribute, if there are any other identifying attributes, the embedded relationships cannot be used.
This will fail:
But this will work:
An "embedded relationship" differs from a non-embedded one in the formatting. In the samples above you will notice the embedded relationship actually specifies the relationship type in the header, "serves". In the example in point 1 you'll notice that the header is "type" and then the relationship type is specified below.
When using an embedded relationship you must only specify the name and class/family of the provider configuration item. Including other attributes will cause the error.
