Assign Costs, depending on the predecessor Hello,I am quite new to PQL and I tried to assign costs to spesific activities depending on the predecessor.When B is followed by C, only C should be assigned with certain costs. When A is followed by C, again C should be assigned with costs, but with a different value. The result should look like this:CaseID Time Activity Costs 150488 07:34 A 150488 08:30 B 150488 09:23 C 0,84 150488 09:45 D 150488 10:34 A 150488 11:45 C 1,56 150488 v E I tried this with the following code: CASE WHEN "ActivityTable"."Activity" = 'C' AND MATCH_PROCESS_REGEX ( "ActivityTable"."Activity", 'A' >> 'C' ) = 1 THEN 1.56 WHEN "ActivityTable"."Activity" = 'C' AND MATCH_PROCESS_REGEX ( "ActivityTable"."Activity", 'B' >> 'C' ) = 1 THEN 0.84 ELSE 0END Unfortunately the table looks like that, so it assigns the wrong costs: CaseID Time Activity Costs 150488 07:34 A 150488 08:30 B 150488
