Programs RFFMCHAN and RFFMCHAT and reassignment of FI documents using ECC6.

Dear Experts,

One customer is upgrading from Enterprise 4.70, Release 110 to ECC 6.0, Enhancement Pack 3.

During testing they notice that programs RFFMCHAN and RFFMCHAT have changed and the related SAP notes indicate that these programs no longer allow reassignment of FI documents.

Is this change valid for both Classic and New GL? If this functionality is being removed, what is the alternative process?

Thanks in advance for any hint.

Best Regards,

Vanessa Barth.
