sap fi account xxx requires an assignment to a co object

sap fi account xxx requires an assignment to a co object
我是想在AR中 直接做 借 ：1000（customer） 1160
贷 :800000(domestic rev) 1000
output tax 160
输入的cost center :4100
但是在模拟的时候出现了 account 800000 requires an assignment to a co object的问题
在ka02 中 800000 已经分配了 默认的 cost center :4100
在okb9 中 800000 对应 cost center :4100 ,profit center:1600
错误信息：
