Message text: Designation not possible as desig./dedesig. flows exist for &1 after &2

What causes this issue?

The system has found that there already exists Designated /
Dedesignated Flows for the Hedged Item / Hedging Instrument after the
supplied Designation keydate because of which this Designation will lead
to over hedging of the underlying (the underlying will be hedged to more
than 100% of its capacity which shall result in heding the same amount
more than once).

System Response

The Designation has been terminated.

How to fix this error?

- Please refer to the Designated / Dedesignated Flows for the
corresponding Hedged Item / Hedging Instrument (The above
functionality is available in transaction TPM100 under the Hedged Item /
Hedging Instrument tabs).
- After carefully studying the above mentioned flows kindly adjust this
amount so that the Designation goes through.
