PLD total function for System Variables which represent sub totals
I want to add a Total to Cost Accounting Summary Report but I am having a problem as follows:
This is a PLD report (I do not use Crystal at the moment) and it shows a Sub Total per Cost Center (shown on a single line when the report is collapsed) but I need the total of ALL COST CENTERS. In the PLD report designer, the Cost Center Total is a System Variable and I cannot find a function that will create a SUM of these. I have Tried the ColSum("F_198") function but this is returning an error - F_198 is the relevant column for the Cost Center Total.
What I am trying to resolve is the fact that this report has no Grand Total adding all cost centers but also the fact that I do not know how to create a SUM of System variables in PLD.
