5 必填 9 建议填写 8 选填

	名称	说明
	上次数据更新 LastDataUpdate	最近一次数据提取或刷新的时间戳。
说明表示数据上次从SAP ECC源系统同步到流程挖掘平台的时间。这有助于了解分析数据的新鲜度以及仪表板可能存在的延迟，对于验证KPI是否反映业务当前状态至关重要。重要性帮助您了解仪表板中的数据更新到了何时。获取途径由提取工具生成（ETL时间戳）示例 2023-11-25T00:00:00Z2023-11-25T06:00:00Z
	事件时间 EventTime	活动发生的具体时间戳。
说明此属性记录活动在系统中发生的准确日期和时间。SAP ECC中的事务数据通常由录入日期（CPUDT）和录入时间（CPUTM）组成。它提供时间维度，可用于计算周期时间、前置时间以及流程步骤之间的时长。重要性这是所有基于时间的分析所必需的数据，包括应收账款周转天数和流程处理速度。获取途径 BKPF表，CPUDT字段（日期）和CPUTM字段（时间）示例 2023-10-12T08:30:00Z2023-10-15T14:22:10Z2023-11-01T09:15:00Z

数据提取指南

如何从SAP ECC获取数据

步骤

在SAP ECC系统中打开事务代码SQVI（QuickViewer）。
为视图输入名称（例如AR_EVENT_LOG），然后点击“创建”。将“数据源”设为“表连接”。
在连接定义界面中，添加主表：BKPF（会计凭证抬头）和BSEG（会计凭证行项目）。请注意，已清账项目可能需要引用BSAD，但BSEG包含所有行项目的主记录。
配置连接条件，将BKPF-BUKRS与BSEG-BUKRS、BKPF-BELNR与BSEG-BELNR、BKPF-GJAHR与BSEG-GJAHR分别关联。这样即可将抬头信息与对应的行项目关联起来。
转到“字段选择”选项卡。请务必选择发票编号（BELNR）、公司代码（BUKRS）、会计年度（GJAHR）和科目类型（KOART），以便筛选客户（类型D）。
添加事件日志时间戳和属性所需字段：凭证日期（BLDAT）、过账日期（BUDAT）、录入日期（CPUDT）、清账日期（AUGDT）和金额（DMBTR）。
若要记录“付款条件已更改”等活动历史，理论上需要连接CDHDR和CDPOS表，但这会严重影响SQVI性能。建议单独提取更改日志，或使用下方查询部分提供的ABAP报表。
保存QuickView并执行。
在选择屏幕中按公司代码筛选，并将科目类型（KOART）设为D，仅输出应收账款数据。
执行报表（F8），并确认列表输出符合预期。
依次选择“系统”、“列表”、“保存”、“本地文件”，再选择电子表格格式，将数据导出到本地文件。
还需进行后处理：SQVI输出的是平面文件（每张发票一行）。您必须使用下方查询部分所述逻辑，将其转换为事件日志格式（每项活动一行）。

配置

数据源：表连接（建议抬头与行项目使用内连接）
主表：BKPF（抬头）、BSEG（行项目）
关键筛选条件：KOART（科目类型）= 'D'（客户），排除供应商或总账行项目
日期范围：按BKPF-CPUDT（录入日期）筛选最近3至6个月的数据，以获取近期流程实例
凭证类型：按BKPF-BLART筛选'RV'（开票凭证）、'DR'（客户发票）、'DG'（客户贷项通知单）
性能：连接BSEG（簇表）可能较慢；如果BSEG性能影响明显，可考虑使用BSID（未清项目）和BSAD（已清项目）
授权：需要具有事务代码SQVI和表显示权限对象S_TABU_DIS的授权

步骤

确定数据库接口：选择对SAP ECC实例执行SQL的方式。通常可通过SAP HANA Studio、DBACOCKPIT，或使用ODBC/JDBC连接的外部ETL工具执行。
确定范围：明确要分析的公司代码（BUKRS）和会计年度范围（GJAHR），避免查询超时。
准备查询环境：确保用户对以下表具有读取权限：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'等占位符和日期范围替换为实际值。
执行提取：运行完整的UNION ALL查询。由于查询包含更改凭证表（CDHDR/CDPOS），执行可能需要较长时间。建议在业务低峰时段运行，或按日期分批处理。
数据转换：输出结果为原始事件日志。根据数据库默认的日期字符串格式，您可能需要将'EventTime'列转换为'YYYY-MM-DD HH:MM:SS'格式。
验证数据：检查行数，并在SAP中使用事务代码FB03核对某个发票编号，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'（录入日期）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。
科目类型（KOART）：查询严格筛选'D'（客户），排除供应商或总账行项目。
更改日志性能：访问CDPOS的子查询会占用大量资源。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假设您使用SAP FSCM模块。如果未使用，这些部分将返回零行，但不会导致失败。

步骤

确认前提条件：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安装所需的Python库。
设置SAP用户：确认SAP用户账户具有S_RFC授权对象，可执行RFC_READ_TABLE函数模块。该用户需要对BKPF、BSAD、BSEG、CDHDR、CDPOS、NAST、MHND、FEBEP、UDM_CASE_ATTR和UKM_PROMISE表具有读取权限。
配置连接：在提供的脚本中，使用您的SAP ECC应用服务器（ashost）、系统编号（sysnr）、客户端、用户名和密码更新connection_params字典。
定义范围：调整脚本中的DATE_FROM和DATE_TO变量，设置提取时间范围。脚本根据录入日期（CPUDT）筛选初始会计凭证（发票）。
运行脚本：运行Python脚本。脚本按顺序提取数据：先获取发票抬头（BKPF），再获取关联的行项目（BSAD），最后使用发票编号作为键提取支持表（CDPOS、NAST等），以减少数据量。
转换数据：脚本使用Pandas库在内存中连接SAP原始表数据，并应用逻辑区分部分付款与标准付款等具体情形，再映射到所需的ActivityName。
构建事件日志：脚本会生成标准化DataFrame，包含InvoiceNumber、ActivityName、EventTime和属性列。每种活动类型（例如付款条件已更改）都会作为一组新行追加。
处理专用活动：脚本包含FSCM（争议/付款承诺）和催款（提醒）相关逻辑。如果您的组织未使用这些模块，对应的DataFrame部分将返回空结果，但不会影响脚本运行。
验证：脚本会在控制台输出提取活动的汇总信息。请检查这些数量是否符合预期。
导出：最终事件日志将保存为CSV文件event_log_output.csv，位于脚本执行目录中。
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（金额）格式正确，再上传至ProcessMind。

配置

RFC_READ_TABLE：用于数据提取的标准函数模块。其默认行宽有限（通常为512字节）。脚本通过仅选择必要列来应对这一限制。
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。如果日期范围很大，可考虑按月循环处理，以避免内存溢出。
日期筛选：提取依据BKPF-CPUDT（录入日期）进行。这样可以捕获时间范围内创建的所有发票，并查找其后续活动，无论这些活动何时发生。
公司代码：脚本使用占位变量TARGET_BUKRS。请将其设为具体公司代码（例如1000），以筛除无关数据。
FSCM和催款：脚本假设使用标准表（UDM_CASE_ATTR、MHND）。如果未启用这些模块，脚本会妥善处理空结果。
更改日志：读取CDPOS（更改凭证）会占用大量资源。脚本通过按对象类别'BELEG'（会计凭证）和特定对象ID筛选来优化查询。
