V4.5. PU 7. Something changed in the PU that broke a PR data entry VI. Worker Comp codes must now be UPPER case if they are part of the import file. Prior to this, lower case codes were accepted. I tried importing by adding a temp field, then calculating the value using a UCS formula. This did work however blank records were not skipped and there wasn't a clear on each record field available for the temp field (not in new BF?). So I ended up reworking the import template to display the WC codes in CAPS. Below is explanation from the 450PU7ProdUpdsSRNs.pdf. Apparently this tweak also made the codes mandated UC.
