For item categories which are not detailed on KEPC, a new temporary entry must be created.
However, majority of the cases, the item category is already included on a range, so the system would not allow adding a new entry.
Example: Item category FGN its included on the range { CH00 - TAPA }.

In that case, you just have to change the range where the item category belongs to.
This range will be identified with the symbol
.
