Python 如何为BAPI调用指定表结构？

如何定义一个表结构来调用BAPI？我想呼叫“BAPI\U PRODORD\U GET\U LIST”

---

我找到了使用RFC_表调用BAPI的正确语法

connection = Connection(user='user', passwd='password', ashost='IP', sysnr='00', client='100')

function_name = "BAPI_PRODORD_GET_LIST"    

value = {u'SIGN':'I',u'OPTION':'EQ',u'LOW':'4711'}

result = connection.call(function_name, MATERIAL_RANGE=[value])

print result

connection = Connection(user='user', passwd='password', ashost='IP', sysnr='00', client='100')

function_name = "BAPI_PRODORD_GET_LIST"    

value = {u'SIGN':'I',u'OPTION':'EQ',u'LOW':'4711'}

result = connection.call(function_name, MATERIAL_RANGE=[value])

print result
