SAP VF02 Release to Accounting Error

Hi 各位

User在用SAP T-code: VF02, Release to Accounting 会卡住且出现一个Error 如下:

G/L account is not defined in chart of accounts 1000
Message no. F5507
Diagnosis
The general master data of the G/L account is not maintained in the chart of accounts 1000.
System Response
Error.
Procedure
Please correct your entry or create the master record.

但是我搜寻了多文却不知道哪出错
VFX3 也有用过, 是一样的讯息
也试过 Environment > Acc. Determ. Analysis > Revenue Accounts 查看过了
但看不出所以然, 不知道有没有人可以解惑呢?
刚接手SAP 真不知道该朝哪个方向查起>"<
Thank you so much.
