Diagnosis
You tried to create statistics with sub-totals or to define a pagebreak for a sort field, but did not take one of the following threeconditions into consideration.
First, sub-totals and page breaks can only be created for fields usedfor sorting.
Secondly, sub-totals/page breaks can only be created for fields ifsorting was also defined for the previous fields in the statistics andif sorting is defined in increasing order.
Thirdly, no fields whose sort number is smaller than the sort number ofthis field may follow after a field for which you want a sub-total or apage break.
For example, if you want to create sub-totals or a page break for thethird field (sequence number 3), you must sort according to this fieldand the two previous fields. Since the sorting sequence still has to bein increasing order, the first field must have sort number 1, thesecond field sort number 2 and the third field sort number 3.
In the following example, you cannot create sub-totals or output pagebreaks. The first field of the statistics (sequence number 1) has sortnumber 2 and one of the following fields has sort number 1. Asub-total/page break cannot be output for any of the fields, not evenfor the first field.
