20170401 ABAP调用CIS webservice

问题：

SAP  abap

SRM java  调webservice 不通，

CIS java  这边的webservice 可以通，

WHY?

key：
请求头，
系统框架的问题，

LF:因为请求头的问题吧
CX:请求头有什么差别？ 

LF:r3发出来的请求，header里面很复杂 ;大概不符合srm的要求,

        这个最开始是 波哥调某个系统的时候出现的,

 

 我搞不清楚为啥会出现，而且其他sap开发人员做接口不会出现这个问题吗，之前一直想找到原因，但还是因为不够执著，且能力也有欠缺未能成功find reason ，

 可能是某些系统框架的问题，

 

abap 《-》java 还是听便利的，从技术角度很多都可行，
