How To Fix T1265 - Data not converted or not fully converted

SAP Error Message - Details

• Message type: E = Error

• Message class: T1 - Financial instruments

• Message number: 265

• Message text: Data not converted or not fully converted

What causes this issue?

This release requires that the datasets for OTC interest rate
instruments (product categories 610, 620, 630) are converted from older
releases. This conversion was either not carried out or not carried out
completely. You cannot therefore continue to process new transactions
or existing transactions.

How to fix this error?

If you have not converted the data, you can do this using transaction
OTC_CONV.
If you have already converted the data, an error has occurred; contact
your system administrator.
