How to select all corresponding counter values for a usage line (contract item, non trackable)
A rather technical question :
For a given Usage_line, I want to select all corresponding counter_values.
Question:
How can I join in a select statement a counter Value (csi_counter_readings) to the Usage line (okc_k_lines_b)?
Through the counter group (cs_csi_counter_groups) the counter is only related to the Service Line.
Perhaps it is possible to join the Usage line to the related Service Line?
