Error while transferring exposure to hedge management

Dear Experts,

While transferring the Versioned Exposure to Hedge Management, I get the error message FTR0899 when the Exposure Amount is Negative. It gets successfully transferred if the Exposure Amount is Positive.

Error Message:

"

Field BAPI_THA_TRANS_FX_MULTIPLE-TRANSACTION_AMOUNT contains invalid field value                                        100,000.0000-"

Am I missing something in Configuration, as this seems to be a standard error message.

Thanks,

Kamal
