CO11N报工使用BAPI_PRODORDCONF_CREATE_TT时无法返回配置错误消息CK466

前些天碰到一个问题，CO11N前台报工时，会触发一个配置E类型的消息CK466，但是在调用BAPI_PRODORDCONF_CREATE_TT时，该消息并不会返回，而是返回S类型消息。

错误重现：

1.kp26取消维护变动价格

2.SM30及SE16N将对应的错误消息类型更改为E

 视图：V_TCMF9

 表：TCMFA

 此时前台执行CO11N就会触发CK466的报错，经过代码追踪，发现问题所在：

在Form det_conf_cost中，其实会捕获到配置的E类型消息，但是只会当以下三种情况时才会捕获错误消息且终止报工。

1.前台处理时：

2.后台处理时：

 3.当订单类型是网络订单时：

除此以外的情况，都不会打上取消标记并下入下面的错误处理逻辑：

所以问题就在于让BAPI调用时也能够将错误消息收集起来，经过对源码进一步分析，错误最终会返回在内表 t_cost_cmfnr 中，只需要找到合适的增强点，调用上述处理函数CM_F_MESSAGES_GET并触发异常no_costing，即可将配置出来的错误消息返回给BAPI的return参数。

解决方案：重写系统预留增强选项。

BAPI返回结果：

同理应该可以解决类似情况的相同问题，以上。
