OM186 - Overview

What causes this issue?

With the aid of account operations, you can insert or delete characters
into or from all selected account keys at specific points.
o With I/<start_position>/<insert_string>, it is possible to insert
characters into the selected account keys at a certain point. For
example, with 'I/03/W1' the string 'W1' is inserted into all
selected account keys at position three.
o With D/<start_position>/<length_del_string>, it is possible to
eliminate characters from the selected account keys at certain
points. For example, 'D/03/02' will cause two characters to be
deleted from all selected account keys, beginning at position three.
The current length of the G/L account field (&V1&) may not be exceeded,
either explicitly or implicitly, by inclusion of <insert_string> or
<length_del_string>. Thus, for example, <start_position> of 'I/09/ABC'
is not allowed for a 10-character G/L account field, whereas 01 - 08 is
permissible.

How to fix this error?
