Last selected company code reached

What causes this issue?

The cash management final balances are displayed on the screen for each
company code and currency after optimization. This means that a new
company code or currency always begins on new page. However, the number
of company codes taken into account by optimization can be smaller than
the number of the company codes entered on the selection screen. This
is the case if not all selected company codes are maintained in the
account table TTRCD and if no payments are saved in the system for
these company codes. The company code displayed can therefore be the
last one although company codes were selected on the selection screen
that are larger than the one displayed.
