Facility charges

Dear experts,

I have a request to create Condition type for Facility charges which is similar to 1204 - Facility fee free (Profile category: 2 - Not utilized).

The difference is that not utilized credit line amount (basis for fee calculation) has to be decreased with each drawing transaction (standard behavior) but not to be increased with repayments of drawing transaction (not standard behavior).

I have tried to achieve these by implementing BADI_TB_FIMA_CF_MANIPULATE, but it is not called in Facility transaction.

Any hint from you would be much appreciated.

Regards,

Jovan
