BAPI_ACC_DOCUMENT_REV_CHECK

Hello,

I´m using the bapi BAPI_ACC_DOCUMENT_REV_CHECK to check whether a FI document is able to be reversed. The bapi works fine, but it blocks the FI document till the programm finishes, so I can´t reverse the document if necesary.

How can I unblock the FI document so I can reverse it?

Thanks!
