How to encode JSON in ABAP before 7.02

阅读更多关于 How to encode JSON in ABAP before 7.02

问题 As Horst Keller mentioned in his ABAP and JSON post, "with Releases 7.02 and 7.03/7.31 (Kernelpatch 116) JSON is supported natively in ABAP". Appartently 7.02 in my case of too generic because the line below: writer = cl_sxml_string_writer=>create( type = if_sxml=>co_xt_json ). returns the error: "The field CO_XT_JSON is unknown, but there is a field with the similar name CO_XT_XOP". So is there any way to easily generate JSON? Edit: Screenshot from SAP - Status 回答1: About the class CL_TREX

Returning a range table in abap

阅读更多关于 Returning a range table in abap

问题 I would like to write a function module that returns a range table. Is that possible and if so, how? 回答1: The structure of a typed range is like this : **Name** **Type** SIGNT VARV_SIGN OPTION TVARV_OPTI LOW your-type HIGH your-type You can create this structure in the dictionary, as well as a table of those, and then use it in the FM signature. Also, a generic structure already exists : RSDSSELOPT (along with a table type RSELOPTION ). 来源： https://stackoverflow.com/questions/3702429

ABAP: Syntax for creating internal table from existing database table

阅读更多关于 ABAP: Syntax for creating internal table from existing database table

问题 I'm new to ABAP. Started learning about internal tables. I was reading on the ways to create internal tables. I came across the following syntax to create an internal table from an existing database table: data: it_mara type table of mara. I'm confused since mara is a table and if both l.h.s and r.h.s are of the same type then shouldn't it be just: data: it_mara type mara. What is the need to convert mara into a table when it is already a table? 回答1: MARA is a transparent table which means

If you are calling so called functional method which has only IMPORTING parameters and optionally one RETURN

SAP S/4HANA使用ABAP获得生产订单的状态

阅读更多关于 SAP S/4HANA使用ABAP获得生产订单的状态

在S/4HANA里，我们如何根据一个销售订单的行项目，查看对应的生产订单状态？双击行项目：点击Schedule line：这里就能看到生产订单的ID和状态了。其中订单的状态存储在表vsaufk里，注意订单和状态可以是1对多的关系。状态的ID和描述信息存储在表tj02t里，所以有了下面的代码： METHOD get_prod_order_status. DATA: lt_status TYPE TABLE OF j_status, lt_text TYPE TABLE OF tj02t, lv_id LIKE iv_prod_order_id, ls_result LIKE LINE OF rt_status_in_s4_format. lv_id = iv_prod_order_id. CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT' EXPORTING input = lv_id IMPORTING output = lv_id. SELECT stat INTO TABLE lt_status FROM vsaufk WHERE inact = space AND aufnr = lv_id. CHECK sy-subrc = 0. SELECT * INTO TABLE lt_text FROM tj02t FOR ALL

问题 How to create a CDS that select all KUNNR from table KNA1 that Customer Number starts for example with A% . I could use LIKE in the where clause but the RHS of the condition have to be static. It should depend on the input parameter from CDS. Is it possible to do it with CDS ? 回答1: I see two options. You get rid of your CDS input parameter handling and move the logic to ABAP. Write your OPEN SQL select on your CDS with like statement. Use CDS Table function and AMDP by pushing the like

ABAP DDD how to correctly implement add/update/remove child from aggregate via RFC?

阅读更多关于 ABAP DDD how to correctly implement add/update/remove child from aggregate via RFC?

问题 I'm trying to follow DDD principles for my current project. Unfortunately I have to use RFCs due to technical constraints, so no OData and no REST. It's quite a long question I hope it's OK to ask this in Stackoverflow. In any case, I have an entity class WorkOrder with a list of Operation objects. I have a WorkOrderRepository class with a SAVE method that only receives a WorkOrder object and is able to save everything (header data, address, etc) in one go. No matter if it's creation, update

问题 I want to add a header row grouping the column headers. Departure Arrival <-- This row is what I want to add Airport Gate Date Airport Gate Date -------- ----- ----- -------- ----- ------- O'Hare A10 10Mar Atlanta G19 10Mar DFW K98 11Mar Denver Z76 11Mar Note that I'm using an ALV List , not an ALV Grid.
