Internal error: Different accounts transferred

What causes this issue?

An internal error occurred. The data transferred to the update module
is inconsistent. You can only edit one G/L account at a time. A single
G/L account consists of the chart of accounts dependent data as well as
the company code dependent data, noting that all company codes have to
be assigned to the same chart of accounts. The tranferred data,
however, contains multiple G/L accounts.
