This article mainly introduces "what is the difference between ABAP regular expression and SPLIT INTO". In daily operation, I believe that many people have doubts about the difference between ABAP regular expression and SPLIT INTO. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the question of "what is the difference between ABAP regular expression and SPLIT INTO?" Next, please follow the editor to study!

Requirements: parse the following three strings concatenated by "/" respectively.

Traditionally, see the function module SKWF_UTIL_IO_FIND_BY_KEY in line 98 of the following figure:

The purpose of this function module is to parse document type: l, document class: CRM_L_ORD and document guid separated by two /.

This function module uses the traditional method of splitting three key and storing them in an internal standard, and then READ TABLE INDEX 1 key 2 and 3 respectively take out each key. It took 42 lines of code.

If you use regular expressions, it takes only 1 line of code:

And the latter is 3 to 6 times faster than the former: because FIND REGEX is implemented in C++ in ABAP Kernel, it is more efficient than doing it on ABAP. Refer to the following performance test comparison results (in microseconds).

At this point, the study on "what is the difference between ABAP regular expressions and SPLIT INTO" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
