Error: All enabled segments of Transaction Flexfield must have a value

Hello,

We are trying to import Invoices from Lease module through the program 'Autoinvoice Master Program'. The request completes successfully but in the output of the second request ' Autoinvoice Master Program' the error message appears, ' Errors: 1) All enabled segments of Transaction Flexfield must have a value (..).

I have checked the

DFF - Transaction Flexfield following the path:

Responsibility: Receivables Manger

Navigation: Setup > Financials > Flexfields > Descriptive > Segments

Title = Line Transaction Flexfield

Code = OKL_CONTRACTS

and for this code we have 3 segments :

'Transaction Id'

'CONSOLIDATED_STREAMS_ID1'

'CONSOLIDATED_STREAMS_ID2'

which don't have any value set attached.
