BAPI_CONTRACT_CREATE for nonvalue materials

I have used BAPI_CONTRACT_CREATE to create a contract for nonvalued materials.  We have upgraded our system and now are getting the error ME083 - Enter Net Price.  Price should be zero.

Before the Upgrade, adding the ACCOUNT and ACCOUNTX for each item removed this error.   I've added ACCOUNT and ACCOUNTX entries, but am still getting the error.

If I try to add a price of .01 then I get the error 06159 "For items without invoice receipts, please enter price 0"

We are on SAP ECC 6.0 SAP_APPL Release 606
