Product Owner change from One customer to another customer
We have upgraded our CRM 04 system to CRM 2007. In CRM 04 we are used to FM 'COM_IL_PRDBP_API_MAINTAIN and COM_PRODUCT_MAT_MAINT_MULT_API' to change product owner from one customer to another customer by passing parameter as update field and destination GUID as new customer. Both of these FM are calling to this include " LCOM_PRODUCT_ILF05" in this lot of enhancements are made in CRM 2007, Now we are not able to product ownership from one customer to another customer through SAP GUI. is there any alternate way to change the product powner ship from one customer to another.
