Subreport calls for filling the value of a linking field
In my attached report there are several subreports. All of the subreports are linked with the main through field PraId and work fine but one subreport, namely Stanowisko, calls for filling the value of field PraId when executing the report. In all subreport and the main report the field PraId comes from the same source - function dbo.SwiadPracyZest. The field PraId is everywhere of value type.
Any idea how to get rid of the problem?
