You do not need to make the correction if you use the method CONVERT_STRUC from this class. |

General system information#

Search in Reports#

Append#
There is a weird shortcut for APPEND.When you record a session, the code is generated like
CLEAR bdctab. bdctab-program = 'SAPMSSY0'. bdctab-dynpro = '120'. bdctab-dynbegin = 'X'. APPEND bdctab.The first CLEAR and the field assignments refer to a structure bdctab.
This structure is the header line (deprecated) from itab bdctab. So bdctab is used in different contexts.
If an ABAP command needs a structure, the header line "bdctab" is automatically taken.
If an ABAP command need an itab, the table "bcdtab" is taken, you can use
APPEND bdctab[]to indicate that the table should be used.
APPEND bdctab is a shortcut and should at least be
APPEND bcdtab to bdctab[]But this is outdated also, though still generated from SAP ECC 6.0.

Execute OS commands on the server#
- function module SXPG_COMMAND_EXECUTE in connection with SM49/SM69
- WS_EXECUTE
- CL_GUI_FRONTEND_SERVICES=>EXECUTE
- TH_POPUP
- call 'SYSTEM' id 'COMMAND'
Remote Execution#
SUBMIT {rep|(name)} ...
Text Manipulation#
| class CL_ABAP_CHAR_UTILITIES | |
| concatenate | |
| strlen | describe field |
Note:
replace all occurrences of ' ' in p_filen with '_' in character mode.will raise an exception REPLACE_INFINITE_LOOP, use the following:
replace all occurrences of regex '\s{1}' in p_filen with '_'.
(or use TRANSLATE)
Using XSTRING#
see xstring
File Handling#
- CL_GUI_FRONTEND_SERVICES=>FILE_*
- OPEN/GET DATASET
- FB EPS_GET*
- FB SCMS*
Date Handling#
Vormonat:DATA: ultimo TYPE d. ultimo = sy-datum. ultimo+6(2) = '01'. " = erster Tag dieses Monats ultimo = ultimo - 1. " = letzter Tag dieses MonatsAchtung: Funktioniert nicht beim Jahreswechsel, hier muss extra geprüft werden.
