Have one issue on Activity type unit measure . early unit measure is "S" i was calculated activity type plan price calculation and run the standard cost estimate-Release also done. now i want to change the unit of measure S into "EA".
But system is throughing error message "Transaction data already exit".
I deleted directly in COST Table level deleted Activity type plant price object. i was try to change unit of measure but still i am getting same error message.
If i will change in master data table level CSLA, what r the implications please give me solution.
