AVEVA E3D™ does not allow any name or specification reference (SPREF) to exist more than once. Identical components can be distinguished by having a suffix added to their SPREFs. ISODRAFT normally removes suffixes from item codes in the material list by recognising the delimiter character which separates the suffix from the rest of the SPREF, and then totals the items together. Items with the same item code but different descriptions can be listed separately using the ITEMCODE SEPARATE command. Alternatively, the user can change the delimiter character using the DELIMITER command. ISODRAFT will not recognise the suffix and so will no longer remove suffixes from item codes in the material list.
