Length of <ADDPART> contents for <ADDTYPE> FORM (overlay) or IMAGE (page segment) exceeds 8 characters (constant). It is truncated to 8 characters.
What happened: You set the Add group <ADDTYPE> tag type parameter to FORM or IMAGE and then specified one or more <ADDPART> tags whose values exceeded the maximum length for those add types of 8 characters. The invalid constant is given. Enrichment used only the first 8 characters of the invalid <ADDPART> value.
What to do: Correct your <ADDPART> tag so the length of its value is 8 characters or less.
