SAP ABAP: Adding leading zero to char or string.

DATA: lv_Belnr(10) TYPE C VALUE '48', lv_Num(10) TYPE N. lv_Num = lv_Belnr. ADD 1 TO lv_Num. lv_Belnr = lv_Num . WRITE lv_Belnr. 2). Using FM CONVERSION_EXIT_ALPHA_INPUT. DATA: lv_Belnr(10) TYPE C VALUE '48'. ADD 1 TO lv_Belnr. CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT' EXPORTING INPUT = lv_Belnr IMPORTING OUTPUT = lv_Belnr. 3). Using UNPACK. DATA: lv_Belnr(10) TYPE C VALUE '48'. ADD 1 TO lv_Belnr. UNPACK lv_Belnr TO lv_Belnr. That's all. Mabuhay!
