外挂系统 -减少SAP用户许可数, 多点操作及时同步SAP

用过SAP 的人都知道SAP 是按照用户数来计算项目费用和年维护费的，所以很多公司设置了共同账号，外挂程序，WDA程序等，各种各样的规避方式。
当然SAP 标准的功能也相对简单化，要实现一些自定义的功能来满足各企业实际业务，那需要进行二次开发，有些顾问公司则通过在SAP 中开发ADDON来实现具体的功能需求，但是这个做法只是满足了业务功能，不能解决SAP 用户数量；
所以我想到了通过开发外挂系统独立于SAP 载体来实现，这样做的好处有：

1）减少SAP 用户数量，即减少SAP 上线费用和年维护费用

2）后期SAP 升级的话，不受SAP 版本的影响

3）外挂系统可以多点使用

4）支持手机端，电脑端，PAD （平板电脑）多终端使用

本方案已经成功用于多个生产企业使用，可以实现仓库部门的生产工单发料，生产工单的报工，生产汇报扣料（手动或先进先出反冲），仓库间库存移动，物料维护，财务凭证维护，仓库销售出货，生产工序转移，生产过程报废，仓库在库报废等等功能，

这里介绍一种：外挂程序

大概逻辑就是：通过外挂程序登录SAP, 用于工号去区分实际账号，登录的时候设置工号：SET PARAMETER ID 'ZLOGIN_USER' FIELD wa_login_user_c. 区分的地方获取工号：GET PARAMETER ID 'ZLOGIN_USER' FIELD wa_login_user_c.即可。

上图可以看到登录操作了，我就不解释了，直接上代码：

*二.登陆时候与用户ip地址绑定登陆
*首先在系统里建立r/3用户和ip地址的对应的关系表userlogon,包括信息(r/3用户名/ip地址),然
*后通过批导入的方式将对应关系数据导入系统表里.
*其次在r/3用户登陆增强(susr0001)写代码验证用户登陆时候的r/3用户名和ip地址在系统对应关
*系表里是否有,通过则允许登陆,未通过则不允许登陆.
*增强代码如下:

*SELECT COUNT(*) INTO xhcount FROM userlogon WHERE bname = sy-uname AND ip = iptxt.
*IF xhcount < 0.
*  MESSAGE i003(ztxbhb).
*  CALL 'SYST_LOGOFF'."退出SAP系统
*ELSE.
*  MESSAGE i002(ztxbhb)."登陆
*ENDIF.
