Hello
You need to define Value Categories and Assign this Value Categories to Cost Elements.
Please see below SPRO Path
- Plant Maintenance and Customer Service-->Maintenance and Service Processing-->Settings for Display of Costs-->Maintain Value Categories
- Plant Maintenance and Customer Service-->Maintenance and Service Processing-->Settings for Display of Costs -->Assign Cost Elements to Value Categories
additionally you need assign this value categories to Cost Key figures as per below settings
Plant Maintenance and Customer Service-->Information Systems for Plant Maintenance and Customer Service-->Assign Value Categories to Maintenance Cost Key Figures
The Old cost will not be displayed in MCI8 report which is posted before above configuration.
It will get posted from your latest when you done the configuration.So create the new work orders after above configuration.
