How to subtract the running total from a target quantity? Dimension error. Hi, I wanted to implement the open target quantity in celonis. Therefore I used the RUNNING_TOTAL function to add up the quantities as shown in the screenshot. After, I wanted to subtract the RUNNING_TOTAL from the target quantity, the code for this looks like that: "CONTRACT_INFO"."KTMNG" - RUNNING_TOTAL("EKPO"."MENGE") That constantly gives me the following error: The running aggregation function RUNNING_TOTAL cannot be used together with a dimension function input. Please check that there are no moving aggregations and dimensions used together as function inputs. Even if I try to use e.g. AVG(), SUM(), LAST() in front of "CONTRACT_INFO"."KTMNG" , it's not working. Only if I use RUNNING_TOTAL() in front of "CONTRACT_INFO"."KTMNG" it's working, but obviously this is giving me wrong results. Thank
