Creates a named list containing all dimensions required for an SDMX series key. Each value is initially NULL and can be filled by the user.
Details
TIME_PERIOD is excluded because time filtering is handled separately through startPeriod and endPeriod.
Examples
if (FALSE) { # \dontrun{
# Requires TUIK_SDMX_API_KEY in the environment.
library(tuiksdmx)
profile <- tuik_flow_profile("DF_TUFE_SDMX_TT01")
filters <- tuik_filter_template(profile)
filters$REF_AREA <- "TR"
filters$FREQ <- "M"
} # }
