FX Gain Loss Creates two lines

Dear All

We have custom AAD for receivable based on MFAR Balancing Method.

When we applied foreign currency Credit Memo to Foreign Currency Invoice, FX Gain Loss lines are expected to be generated. Ideally either Loss or Gain (Only One Line) should be generated.

Business case is BSV of INV and CM is different. On application, the Gain/Loss account should default from System Option and BSV of Receivable account of Invoice should get replace. This is perfectly working on Seeded MFAR Bal AAD.

But in our custom SLA we are getting two lines with different BSV, one for Gain and one for Loss. The BSV is defaulting from Inv Receivable BSV and CM Receivable.
