刚开始做采购收货时，遇到如下问题

刚开始做采购收货时，遇到如下问题：

Check table 169P: entry 1686 does not exist

Message no. M7001

Diagnosis

In table 169P the entry 1686 is missing.

Procedure

Make sure your entries are correct.

If table has not been maintained correctly, please inform your systems administrator.

解决方法：1、进入IMG-materials management-logistics invoice verification-incoming invoice-edit po supplement text in invoice verification [T-CODE:OMR8]进行维护；

2、或者更狠一点，直接SM30，修改T169P

说明：

In this step, you can maintain the display of purchase order supplement texts when an incoming invoice is entered against a purchase order.

Activities

1. Choose Purchase Order Text: General.

• For each company code, specify whether the invoice verification clerk is to receive a message if notifiable PO texts exist for the purchase order against which he or she is entering an invoice.

2. Choose Notifiable Purchase Order Text Types.

• If provision has been made for a message under Purchase Order Text: General, you can specify via Notifiable Purchase Order Text Types the text types (such as header text, dates/times, terms of delivery) in the case of which the invoice verification clerk is to receive a message. You can do this for each company code.

意思是在做发票校验时，需设置好发票是否自动带出之前PO的相关说明文本，以上第一个步骤指定是否带出PO text，第二个步骤指定要带出哪些PO text

为了在收货时不让本文标题的错误出现，必须至少在第一个步骤里把公司代码加入进来，即不管你要不要你的发票带出PO text，你都得在这个步骤里把公司代码加入进去。

不过我有点奇怪，俺不是在做收货嘛，怎么检查到发票校验这个层面了。
