Pic01 Error

Hi everybody,

- i,ve created a FFFC material type in MM01;

- defined a Manifacturer Part Profile in Customizing;

- created some HERB (interchangeable parts) (in Basic Data 1 view i defined the Manufacturer part Profile for each of these materials);

Now i want to define in PIC01 the HERB material in the FFF class. When i insert the FFFC code this error is shown:

What is my mistake?

Regards
