Summary :
After a Unicode conversion, Report Writer extracts (GREP table) are unusable and should be deleted before the conversion with transaction GRE0 to prevent unnecessary conversion of large data sets. Generated Report Writer programs (GRRT table) must be re-generated, deleting old data with RGRDLINC to avoid unnecessary data conversion. An automatic regeneration occurs when a report group is called for the first time post-conversion. Report groups can also be regenerated en masse as per Note 78109.
Key words :
generated report writer programs, report writer report groups, report writer programs, report writer reports, long-term archiving, avoid converting data, table grrt occurs, table grrt unnecessarily, generated programs, report groups
