Writing JSON serializer

由 蹲街弑〆低调 提交于 2020-01-24 19:47:10
问题 If I want to develop a serializer for a language for which one doesnt exist already (e.g. ABAP), what could be the efforts involved in it? Does it involve merely writing "text equivalent" of ABAP serialzer - how would I tackle complex objects. What would be the best starting point for this? 回答1: Update: Starting with Releases 7.02 and 7.03/7.31 (kernel patch 116), JSON is supported natively in ABAP - check this blog by Horst Keller. You should search for ABAP and JSON using site:sap.com first

MD5 hash of a file in ABAP

由 不羁的心 提交于 2020-01-24 05:19:26
问题 I want to generate a MD5 hash of a text file in ABAP. I have not found any standard solution for generating it for a very big file. Function module CALCULATE_HASH_FOR_CHAR does not meet my requirements because it takes a string as an input parameter. Although it works for smaller files, in case of a for example 4 GB file one cannot construct such a big string. Does anybody know whether there is a standard piece of coding for doing that (my google efforts did not bring me anything) or maybe

How to use REUSE_ALV_FIELDCATALOG_MERGE function module?

由 喜你入骨 提交于 2020-01-23 12:26:27
问题 I'm trying to use the function module REUSE_ALV_FIELDCATALOG_MERGE to pass the field label in ddic to display in the column header of the alv report. But, that didn't work. If I comment the I_STRUCTURE_NAME = 'TY_YNAH_CUS_OBJ_REQ' line, it give me runtime error state The ABAP program lines are wider than the internal table. But if I uncomment it ,the program still did not work REPORT YALV_TEST. tables sscrfields. type-pools : slis. "CREATE STRUCTURE -1 TYPES: BEGIN OF TY_YNAH_CUS_OBJ_REQ,

sap abap alv report fill gap between documents

问题 I was trying to challenge myself to make an ALV report that displays all the data by company code. but some document number has a gap. I want to fill the gap between missing number For example: last index value: 20012 then next value is: 20014 How do I able to insert 20013 in the grid if the report is using all the data that exist in internal tables? Thanks. 回答1: This is just blind text typing, but I hope you are able to understand it ... should be quite simple. Dont expect complete code,
