&NOTES&
In the case of cross-company code sales documents, it may be necessary
to start the reassignment for the object types <LS>Sales Document</> and
<LS>Sales Document (Cross-Company)</> separately to prevent one from
blocking the other.
It is also possible that different items of the same document are being
processed at the same time by parallel reorganization processes and the
lock is set for the entire document. For this reason, you may have to
start the account assignment change more than once.
