Parking document with BTE 00002218

Dear all,

I want apply some checking when parking a FI document, I searched in the forum that BTE interface 00002218 with function SAMPLE_INTERFACE_00002218 can be used for parking a FI document.

I have also copied SAMPLE_INTERFACE_00002218 to a function ZFI_00002218.

When I map the function to the event 00002218, I can't find the process 00002218. Can I ask are there any steps I have missing?

Thanks

Sunny
