NAMGVSUBOFLOW, Subscripted name hhhh...tttt is too long to be represented in the database using collation value #nnnn
GDE Error: This indicates that the subscripted name is too big to be represented in the database (exceeds the maximum limits of GT.M for the key size). The message also reports the alternative collation nnnn which was used to arrive at the subscript/key representation inside the database. The head (hhhh) and tail (tttt) of the long subscript is displayed with a ... in the middle.
Action: Specify a shorter subscripted name.
