Field help (CUMSCOLPJM) 

Click this check box if the Financial overview calculation engine must total the value retrieved by this SQL query for subcolumn 1.

If you do not require the values in subcolum 1 to be totalled, leave this check box clear. The quantities will only be displayed in the detail screen for the selected object code (as launched from the Actions icon for an expense line in a financial overview).

 Subcolumn 1 is typically used for quantities. You should only select this check box if you are sure the SQL query retrieves quantities that can be converted and totalled in the subcolumn.

 The default only assumes an aggregation of time unit. Consolidating (totalling) product units is not advisable as units can vary from one document type to another.
