I created a FM with import parameter MATNR, Remote Enable is set.
When I attach this FM to a business object by using SWO1, it says:
"Data type MATNR cannot be used for methods"
The reason is:
"You tried to create a method in the BOR with a data type that is not supported. Only data elements and structures are allowed as reference types for parameters in the BOR."
But when I change the parameter in the FM, not passing by value, It says:
"Reference parameters are not allowed with RFC"
If I set the FM to not remote call enable, I cannot attach to the business object type.
How can I solve this problem? Thanks!
