Hello!
I'm working with CR (2011) for just 2 days, so there are still problems with the codes and so on.
My problems/questions so far:
- is it possible to use common SQL or PL/SQL commands inside of a report?
- is it possible to get access to group - results or calculate them by myself?
- How to use a global variable so that it's not 0 in the report header?
Those are obstacles, if you want to evaluate cumulated (minute)-values, set back to 0 after each group of work-shifts.
Each shift has a defined begin- and endtime. Not all shifts got a record in at the end of the shift (but they schould), so if this record does'nt exist, the resttime to the shiftend should be added to the last record of a group(shift).
Status:
I inserted a group-result with the group-result-operation 'maximum' for each column.
Those values are correct for the individual shifts (except for the ones where there is no record at the end of a shift), and i used a diagram visualizing the values.
The problem is, that a total-diagram is wanted in the report header, but its values cant be calculated with the the group-result-options, because by using 'summarize' all already cumulated values would be summed up again. By using 'maximum' - only the highest value of each column from all shifts would be taken.
I tried to solve this problem with a global variable, which - per record at the end of a shift - is increased by this value.
But beside the problem that shifts where no record is at the end of the shift are ignored, i noticed that the global variable shown in the report header always has the value 0.
I've got the same problems in my subreport.
I hope the problem is still understandable,
ty for answers!
