Background on JD Edwards Report Engine (by Vincenzo Caserta)
According to Vincenzo Caserta, JD Edwards OneWorld (Tools release B7333) relied on the classic PeopleSoft-style RDA engine. In this legacy environment, the Report Design Aid (RDA) was limited in horizontal size. Oracle documentation shows RDA layouts extended only to column 227, recommending a physical page limit of 45 inches. In practice, this created a 22" wide report limit—going beyond it caused rendering issues.
