如何从SAP ECC获取数据

步骤

在SAP ECC系统中访问事务SQVI（QuickViewer）。
为视图输入名称，例如AR_EVENT_LOG，然后点击Create。将Data Source选择为Table Join。
在Join定义界面中插入主表：BKPF（Accounting Document Header）和BSEG（Accounting Document Segment）。请注意，对于已清账项目，您可能需要引用BSAD，但BSEG包含所有行项目的主记录。
通过连接BKPF-BUKRS与BSEG-BUKRS、BKPF-BELNR与BSEG-BELNR、BKPF-GJAHR与BSEG-GJAHR配置连接条件，将抬头信息关联到具体行项目。
转到Field Selection选项卡。必须选择Invoice Number（BELNR）、Company Code（BUKRS）、Fiscal Year（GJAHR）和Account Type（KOART），以便筛选Customer（Type D）。
添加事件日志时间戳和属性所需字段：Document Date（BLDAT）、Posting Date（BUDAT）、Entry Date（CPUDT）、Clearing Date（AUGDT）和Amount（DMBTR）。
对于“Payment Terms Changed”等活动历史，理论上需要连接CDHDR和CDPOS表，但这会导致SQVI严重的性能问题。建议单独提取变更日志，或使用Query部分提供的ABAP报告。
保存QuickView并执行。
在选择界面按Company Code筛选，并将Account Type（KOART）设为D，仅保留应收账款数据。
执行报告（F8），确认列表输出符合预期。
依次选择System、List、Save、Local File，并选择Spreadsheet格式，将数据导出到本地文件。
需要进行后处理：SQVI输出是平面文件，每张发票一行。您必须使用下方Query部分所述逻辑，将其转换为事件日志格式，即每项活动一行。

配置

数据源：Table Join（建议对抬头与项目使用Inner Join）
主表：BKPF（Header）、BSEG（Item）
关键筛选条件：KOART（Account Type）= 'D'（Customer），排除供应商或总账行项目
日期范围：按BKPF-CPUDT（Entry Date）筛选最近3至6个月，以获取近期流程实例
凭证类型：筛选BKPF-BLART中的“RV”（Billing Doc）、“DR”（Customer Invoice）和“DG”（Customer Credit Memo）
性能：连接BSEG（Cluster Table）可能较慢；如果BSEG性能不足，可考虑使用BSID（Open Items）和BSAD（Cleared Items）
授权：需要SQVI事务和S_TABU_DIS表显示权限

步骤

确定数据库接口：明确如何对SAP ECC实例执行SQL。通常可通过SAP HANA Studio、DBACOCKPIT，或通过ODBC/JDBC连接的外部ETL工具完成。
定义范围：确定要分析的具体Company Codes（BUKRS）和Fiscal Year范围（GJAHR），以避免查询超时。
准备查询环境：确保您的用户拥有以下表的读取权限：BKPF、BSEG、CDHDR、CDPOS、MHND、NAST、FEBEP、FEBCL，以及UDM_CASE_ATTR（如使用FSCM）。
配置参数：在提供的SQL脚本中，将'YOUR_COMPANY_CODE'和日期范围等占位符替换为实际值。
执行提取：运行完整的UNION ALL查询。由于包含变更凭证表（CDHDR/CDPOS），查询可能需要较长时间。建议在业务低峰期运行，或按日期拆分为较小批次。
数据转换：输出将是原始事件日志。根据数据库默认日期字符串输出，您可能需要将'EventTime'列格式化为'YYYY-MM-DD HH:MM:SS'。
验证数据：检查行数，并在SAP中将特定Invoice Number与事务FB03进行比对，确保历史记录一致。
导出：将结果集保存为CSV文件。
导入ProcessMind：将'InvoiceNumber'、'ActivityName'、'EventTime'和'SourceSystem'列映射到流程挖掘工具中的对应字段。

配置

日期范围：强烈建议按“BKPF.CPUDT”（Entry Date）筛选，将范围限制为最近6至12个月，以提升性能。
公司代码（BUKRS）：始终按具体公司代码筛选，避免混合不同逻辑系统的数据。
账户类型（KOART）：查询严格筛选“D”（Customers），排除供应商或总账行项目。
变更日志性能：访问CDPOS的子查询会消耗大量性能。请确保OBJECTCLAS和OBJECTID上已启用数据库索引。
FSCM使用情况：提取争议和付款承诺的部分默认使用SAP FSCM模块。如果未使用，这些部分将返回零行，但不会导致查询失败。

步骤

前置条件验证：确保已安装Python 3.x，并在计算机上正确配置SAP NWRFC SDK。使用pip install pyrfc pandas安装所需Python库。
SAP用户设置：确认SAP用户账号拥有用于执行RFC_READ_TABLE函数模块的S_RFC授权对象。该用户需要对BKPF、BSAD、BSEG、CDHDR、CDPOS、NAST、MHND、FEBEP、UDM_CASE_ATTR和UKM_PROMISE表拥有读取权限。
连接配置：在提供的脚本中更新connection_params字典，填入您的SAP ECC应用服务器（ashost）、系统编号（sysnr）、客户端、用户名和密码。
范围定义：调整脚本中的DATE_FROM和DATE_TO变量，定义提取窗口。脚本根据录入日期（CPUDT）筛选初始会计凭证（发票）。
脚本执行：运行Python脚本。脚本按顺序执行提取：首先获取发票抬头（BKPF），然后获取关联行项目（BSAD），最后使用发票编号作为键获取支持表（CDPOS、NAST等），以减少数据量。
数据转换：脚本使用Pandas库在内存中连接原始SAP表数据。它会应用逻辑识别特定场景（例如Partial Payments与Standard Payments），并将其映射到所需的ActivityName。
事件日志构建：脚本构建包含InvoiceNumber、ActivityName、EventTime和属性列的标准化DataFrame。每种活动类型（例如Payment Terms Changed）都会作为一组新行追加。
处理专用活动：脚本包含FSCM（Dispute/Promise）和Dunning（Reminders）的处理逻辑。如果您的组织未使用这些模块，相应的DataFrame部分将返回空结果，但不会导致执行失败。
验证：脚本会在控制台打印提取活动摘要。检查这些数量，确认其符合预期。
导出：最终事件日志将保存为脚本执行目录中的event_log_output.csv文件。
后处理：打开CSV文件，检查日期格式（建议使用ISO 8601），并确认数值（Amounts）在上传到ProcessMind前已正确格式化。

配置

RFC_READ_TABLE：用于提取数据的标准函数模块。该模块默认限制行宽（通常为512字节）。脚本通过仅选择必要列来处理这一限制。
分块处理：对于大型数据集，脚本会使用初始BKPF查询中获取的凭证编号筛选次级表。如果日期范围过大，可考虑循环按月处理，避免内存溢出。
日期筛选：提取由BKPF-CPUDT（Entry Date）驱动。这可确保捕获时间窗口内创建的所有发票，并进一步查找其后续活动，无论这些活动何时发生。
公司代码：脚本使用占位变量TARGET_BUKRS。请将其设置为具体公司代码（例如1000），以筛除无关数据。
FSCM和催收：脚本默认使用标准表（UDM_CASE_ATTR、MHND）。如果这些模块未启用，脚本会妥善处理空结果。
变更日志：读取CDPOS（Change Documents）会消耗大量性能。脚本通过按对象类别“BELEG”（Accounting Doc）和具体对象ID筛选进行优化。
