Flexfield issue while importing AutoInvoice

Hi,

I am trying to import an invoice using the Import AutoInvoice process. Following is the error which I face as the program ends in error.

---------------------------error -------------------------------------

The context for flexfield Contract Invoices is missing or invalid.

---------------------------!!!!!-------------------------------------

I have checked the Context in both Invoice Transactions Flexfield as well as Line Transactions Flexfield and the context is enabled for both the flexfields.

Further, even after entering different context in the excel data while importing, I still face the same issue.

Regards,

Supriya
