在运行FB70录入相应的会计凭证的时候,报错：在表T030B中，AGD的输入丢失。
解决方案：
第一种：输入事务代码FBKP，
进入其中：Automatic postings
进入其中：Outgoing invoices
进入：Customer Item on Outgoing Invoice AGD
把其中借贷的PK码填上去错误消失（PK码此处填40、50不对，应为01和11，如果填40、50，FB70运行时会报错，PK码没有定义】
在SAP community中搜索到正确的填写方法：
OBXW
AGD--Customer item on Outgoing Invoice
Debit:01--Invoice, Credit:11--Credit memo
AGS--G/L Account item on Outgoing Invoice
Debit:01--Invoice, Credit:50--Credit entry
AGX--Customer item with special G/L indicator
Debit:09-- special G/L Debit, Credit:19-- special G/L Credit
OBXJ
EGK--Vendor item in incoming invoice
Debit:21--Credit memo, Credit:31--Invoice
EGS--G/L item in incoming invoice
Debit:40--Credit entry, Credit:50--Credit entry
EGX--Vendor item with special G/L indicator
Debit:29-- special G/L Debit, Credit:39-- special G/L Credit
OBX1
SAK-- G/L Accounting posting
Debit:40--Debit entry, Credit:50--Credit entry
第二种方法：通过SPRO后台进行配置
具体路径为：Financial Accounting ---> Accounts Receivable and Accounts Payable ---> Business Transactions --->Outgoing Invoices/Credit Memos
---> Outgoing Invoices/Credit Memos - Enjoy ---> Define Posting Key for Outgoing Invoices/Credit Memos
接下来同第一种方法操作。
