When expense results in a linked OPEX model appear under the 'Uncategorized' location dimension value, it indicates that the source personnel sheet data does not carry location dimension information. In Workday Adaptive Planning, when a cube or modeled sheet references data from another sheet via a linked account formula, the dimension values present in the results are determined by the dimension values present in the source data. If the personnel sheet was not planned with the location dimension --- meaning location was not used as a planning axis when entering headcount data --- then the location dimension has no value assigned to those rows, and the system classifies them as 'Uncategorized' in the OPEX output. The solution is to configure the personnel sheet to include the location dimension as a planning axis, so that headcount entries are tagged with specific location values. Adding formula term modifiers for location in OPEX would not resolve the root cause, which is missing dimensional data at the source.
