For the record, change log data can be deleted, there are no issues with

摘要:作为在去年10月份SAP公司大会上隆重推出的产品,不得不提,HANA是十分强大的,它与BW是相辅相成的,但又可以独立于BW之外,虽然建模功能不如BW强大,但是它的ETL较之BW快上了至少10倍以上,速度和可实时性是HANA绝对的优势,它的快不仅仅是把数据都放到内存中应用,最重要的是它把原有的最底层数据存储由原来的行排列变成了列排列,其中SAP的HANA专家还指出应用了几个新玩意,CE和DS,以及SUP+HANA平台的概念,HANA里的Attribute View,Anaylisal View和Calculation View等等,其实就是BW中的InfoObject,Cube,其中Calcul

摘要:在“转换”中,最重要的有三种类型的例程,开始例程,转换例程及结束例程;此外还有专家例程,反向例程。开始例程:开始例程在每个数据包开始进行转换时运行。开始例程没有返回的值,它直接对数据包进行计算、修改或删除等操作,将操作的结果直接保存在数据包中进行后续的转换步骤。当然,开始例程也可以访问和操作SAPBI 系统中的其他数据库表。转换例程:则是在每笔数据传输过程中,对数据进行的一个转换,例如数据根据条件进行的匹配转换。当在每个字段的详细规则中,选择例程的规则类型就会弹出对话框来贴些转换例程。结束例程:结束例程对经过转换规则转换后的数据进行操作,它操作的是一个与目标对象字段结构一致的表结构。与开始例程

摘要:1.可以使用R3标准数据库表或者定义表(需注意对于金额或者数量字段,必须有参照表。如果做为数据源的表自己含有金额单位或者数量单位,并且参照表位表 本身,那么此表可以直接作为数据源使用;如果做为数据源的表本身没有金额单位或者数量单位,参照表另外的表,则使用该表做数据源时会报错。BW的机制好像 是表本身金额和数量字段必须有参照表,并且参照表位此表本身,如果参照表与想做为数据源的表不是一个表,则无法取的相应的单位。因此如果参照表为其他表, 则可能需要建立视图,在视图中关联参照表取得单位),自定义表往往需要通过比较复杂的程序计算出结果,然后将程序输出结果存在自定义表中,然后通过自定义 表做为一般的数.

摘要:在BW中,存在两种数据抽取方式,完全更新与增量更新,完全更新是每次把截至到某个时间的数据全部抽取,增量抽取则只抽取上次和本次抽取之间更新的数据,很显然,增量抽取能够提高系统效率,根据SAP帮 助的说法,增量更新又分为时间戳和增量队列两种方法,其中财务数据的抽取为时间戳增量法,后勤数据的抽取为增强队列法。对于增量更新,都需要先对数据抽取 进行初始化,然后再进行增量的抽取。对于时间戳增量法,系统存在一个延迟时间,即时间戳设置时间与记账时间的差异,比如时间戳是根据创建时间(或输入时 间)来确定是否更新的依据,而在抽取开始时(时间戳已标记),此时凭证已创建而未记账(即未更新至数据库),则此次无法抽取.

摘要:在BW3.5中,一個infosource可以assign多個datasource,他們直接通過transfer rules連接。他們之間是1:N的關係。同一個infosource可以有多個data target,比如2個不同的ODS可以分配同一個infosource,他們是通過update rules鏈接。同樣,同一個data target也可以有多個不同的infosource,他們之間是N:N的關係。在BW7.0中,因為很少用到infosource了,所以datasource和infoprovider之間的關係是N:N。也就是說,同一個datasource可以和多個infoprovider建
