RE: Getting more fields on PO using report writer
Hi Nancy,
When a temp table is created for default reports in Report Writer it is usually so the code behind the report can avoid 'one-to-many' table relationships, which may have been the case with the original design if the PO Line table is not a default table option.
Such table links may cause issue in RW as it is a one-pass system and doesn't have the ability to 'go back' into processed report data to recalculate additional field content for display; instead it gathers, calculates, displays and then empties a singular line of data before moving on to repeat the process on the next line.
As such, even if can link the table successfully chances are the code will not be able to pick it up correctly afterward.
However, if the fields are necessity you can always test linking the additional table to see if you can get a consistent result to use in production.
You are correct you will also have to create relationships from existing tables to create such an table availability. The best description of this feature is Chapter 12 (Table Relationships) of the Report Writer user guide.
Best Regards,
Jeff
