Delete Funds Centers in FM Area

Hi Experts,

We have BCS active in SAP S/4 HANA, we are in a test client and We want to delete funds centers in FM area, before executing  this transaction, we executed "Delete commitment data and actual data (FM_DLFM)"  and " Delete budget data (RFFMKU_DEL_DATA)". The tables FMIOI, FMIFIIT and FMBDT are empty, but in table FMIT there are 33 records with zero amount. I think that records are preventing the fund center to be delete.

When I execute the transaction OFDF to delete, I get  Message no. F6570 : Function not allowed, funds center XXX was already posted to. Also in transaction SLG1, I get Message no. FMUP087:  Transaction data exists for FM area XXX in table FMIT.

Our Funds Center are not year dependent.  How can I delete the FMIT records?.

I have used the transaction FMAF, but It doesn´t work.  

Thanks in advanced for your comments.
