Development Description: during SAP system maintenance, sometimes we need to modify some table data, but many tables cannot be directly modified in tcode: SE16, the sap id used does not have the permission to modify the debugging data. How can we modify the data? Idea --> ABAP Program All SQL update statements in are permitted to be executed, as long as we can dynamically generate the ABAP code to modify the table field for dynamic execution! Development Technology: 1. SQL Code Writing Technology 1. dynamic program code generation technology 2. considerations for ABAP dynamic program execution: the SQL syntax must be accurate and the modification conditions must be accurate. The program code does not violate the rule of Data uniqueness after data modification: the following report is z_cbo_abap_02 message-id zp no standard page heading. data: fcode like sy-ucomm,
Changed like s38e-buf_varied,
Save_tabix like sy-tabix,
Tabix_count type I,
Select_key (10) type C,
Etc (80) type C,
Update_flag type C,
Line_cnt type I,
Prog (8) type C,
MSG (120) type C,
Msg_text (72) type C,
Confirm_flag Type C. Data: itab_ SQL like abapsource occurs 0 with header line,
Itab_prog like abapsource occurs 0 with header line. start-of-selection. * program execution directly enters the ABAP code editor
