System Response

How to fix this error?

For securities/listed derivatives:
Check the position for key date &v1& using the
<DS:TRAN.TPM26>Position List for Quantity Ledger Positions</> function.
For money market transactions:
Check the cash flow.
Examples
You enter a sale of securities for more units or nominal amounts than
are available in the quantity ledger on the key date.
You enter a capital reduction in a money market transaction for a key
date on which the nominal value has already been reduced to zero as a
result of installment repayments.
You enter a capital reduction in a money market transaction after the
final repayment. This is also the case if the start of term is defined
as <LS>Inclusive</> and a capital reduction has a calculation date that
is the same as the end of term. Since the end of term is considered
<LS>Exclusive</> in this case, the capital reduction occurs after the
final repayment.
