abp框架要学多久

abp框架要学三个月。根据查询相关公开信息显示，相对其他语言，ABAP语言非常简单，很好学，而且很多功能就是英语本身的意思，好理解，三个月左右就可以入门。

sap难学吗_sap好学吗

看你是想学哪个方向了：

它主要是分为业务方向，比如HR模块、比如FI模块、或者PP模块等等，这些都是需要很强的逻辑性，需要的经验也很多。

还有开发方向，需要懂abap语言，对于开发类了解不多，不作解释。

还有实施方向，也就是BASIS。BASIS的难度比较大，它需要学很多东西：

数据库、网络协议、硬件、各种操作系统、各种数据库等等，并且basis需要的经验要求非常高，我记得看过一句话叫，5年才刚入门。

还有一个BW，它是出报表的，不过应该也属于业务模块中的，用的也比较多，不过BW不知道在HANA出来以后前景会如何。这些都要慢慢了解。

非要说它难不难的话，初入门真心不容易，如果有人带，参与的项目机会多的话，那你学起来也不会很难。如果自学的话，还是没那么容易的。

纯属个人见解。

以上。

做java一年了，想转abap开发，懂行情的人给点建议吧！

踏踏实实做完一年java开发的人学习abap跟玩儿似的，abap语言很简单的，你可以自己在网上搜些基础教程看看就明白了，无非就是些工作区，内表，function，alv，dialog等等，当然实际的话还是需要一个开发环境来练手的，年纪大的的确不太适合做了，毕竟做abap开发的都有颗转做业务的心，单纯做abap开发没啥意思，主要的还是熟悉sap的流程，业务方面的东西才是精髓！

[讨论]ABAP难学吗

俺非高手,SAP是有前途,估计ABAPer就难说,MD,现在不是有招ABAPer才给那么1000大元就打发你走的吗?就是因为这该死的破ABAP TMD太容易学了,去年我学ABAP时,大概花了三分钟然后一周内俺就将BS sheet, P&L sheet, FI doc. print全给整出来了,因为比起自己写个delphi control,搭好一Java系统架构小小的ABAP太微不足道了.是的,看看SE80,ABAP也可弄interface,Class(类Java),BADI等,可是企业通常连dialog programming都用不到上(其实这些鸟东西也不难,一句话,当你对任何一门语言玩熟的话其他任何语言都是极其容易上手的),你只要熟悉那破SAP query, script form ,smartform再整几个破report就Ok,如需要再整几个enhancement,从某种程度上, 如你没有志向是到SAP AG给破SAP升级,能写report就Ok,没前途呀,兄弟! 所以俺溜的贼快跑去混FICO了,听说这玩意比价容易蒙俩小钱,哈哈.有同感!ABAP是低级的，业务才是高级的；ABAP是无聊的，业务是多变的。
