You are manually running an import and wish to only import ASP values. You select that you wish to Import ASPs only at the Data Import options step and have mapped or used a field mapping to import these. When you look at the report after the import, however, the ASPs are now showing on the Units line and not the ASP line.
When creating/using a Field Mapping, the Data Type variable was not set and the data was imported into the Units Data Type by default.
When importing ASPs only, check that the Data Type variable is using the Complex Expression "Price" at the Field Mapping stage. You should then find that the ASPs have been added correctly to the ASP line in your report.
