The property "RowGoverning4CostlyFunctions" is a hidden limit that was introduced in Strategy to prevent memory issues or crashes when many complex metrics are used at the same time. This property limits the maximum amount of rows to 80,000.
If you surpass this row limit, your metric values appear as null and the following error message appears in the DSSErrors.log:
"DE89740: The calculation of the R function is costly on the xxxxx rows. Skip the calculation given the row governing is set as 80,000”
The following workarounds apply to Strategy 2019 and newer, as well as versions prior to Strategy 2019.
