Do you need to create or modify tables or structures in the Workbench from an ABAP program? It is easier than you...
think. This example demonstrates the use of the DDIF_TABL_GET, DDIF_TABL_PUT and DDIF_TABL_ACTIVATE function modules from the SDIF function group. First, it reads information from the COPA table CE31000 and then creates and activates a new dictionary structure with those fields whose name starts with 'VV'.
DATA: t_dd03p LIKE dd03p OCCURS 0 WITH HEADER LINE, wa_dd02v LIKE dd02v . START-OF-SELECTION . CALL FUNCTION 'DDIF_TABL_GET' EXPORTING name = 'CE31000' IMPORTING dd02v_wa = wa_dd02v TABLES dd03p_tab = t_dd03p. DELETE t_dd03p WHERE fieldname(2) NE 'VV'. wa_dd02v-tabclass = 'INTTAB' . wa_dd02v-tabname = 'YCOPAINC' . wa_dd02v-as4user = sy-uname . wa_dd02v-as4time = sy-uzeit . wa_dd02v-as4date = sy-datum . wa_dd02v-applclass = '' . wa_dd02v-authclass = '' . FIELD-SYMBOLS: <fs> LIKE LINE OF t_dd03p. LOOP AT t_dd03p ASSIGNING <fs> . <fs>-tabname = 'YCOPAINC'. ENDLOOP . CALL FUNCTION 'DDIF_TABL_PUT' EXPORTING name = 'YCOPAINC' dd02v_wa = wa_dd02v TABLES dd03p_tab = t_dd03p. CALL FUNCTION 'DDIF_TABL_ACTIVATE' EXPORTING name = 'YCOPAINC'.
