目的：用户希望用BDC实现，自动创建EPIC_PROC银企直连的"付款建议"按钮功能
(本想实现以下步骤，创建付款状态，但无法实现)
难点：EPIC_PROC事务码直接录屏没办法捕捉到该按钮(失败了很多次)
解决方法：创建一个新程序，调用标准函数 EPIC_PR_SEL_POPUP，对该事务码进行BDC录屏
解释：EPIC_PR_SEL_POPUP 该函数是通过debug事务码EPIC_PROC的时候，定位到，弹出"付款建议"窗口时，是调用的该函数，所以我们可以绕过前边步骤，直接调用该函数，弹出"付款建议"窗口进行录屏，成功！
步骤：
1）创建程序：ZFICOM008（事务码：ZFICOM008），调用：EPIC_PR_SEL_POPUP
*&---------------------------------------------------------------------*
*& Report ZFICOM008
*&---------------------------------------------------------------------*
*&
*&---------------------------------------------------------------------*
REPORT zficom008.
CALL FUNCTION 'EPIC_PR_SEL_POPUP'.
2）DBC录屏：调用事务码ZFICOM008，会弹出以下窗口，成功录屏
