Answer 1

hi
good
check this code
) Defining the table records and the field symbol in a similar type.
just an ordinary standard table
TYPES: BEGIN OF it_vbak_line,
vbeln LIKE vbak-vbeln,
vkorg LIKE vbak-vkorg,
vtweg LIKE vbak-vtweg,
spart LIKE vbak-spart,
kunnr LIKE vbak-kunnr,
END OF it_vbak_line.
DATA: it_vbak TYPE TABLE OF it_vbak_line.
FIELD-SYMBOLS: <it_vbak_line> TYPE it_vbak_line.
or as a screaming fast hash table for keyed reads
TYPES: BEGIN OF it_vbpa_line,
vbeln LIKE vbak-vbeln,
kunnr LIKE vbak-kunnr,
END OF it_vbpa_line.
DATA: it_vbpa TYPE HASHED TABLE OF it_vbpa_line
WITH UNIQUE KEY vbeln.
FIELD-SYMBOLS: <it_vbpa_line> TYPE it_vbpa_line.
2) In ITAB processing, utilize the ASSIGNING command.
loop example
LOOP AT it_vbak ASSIGNING <it_vbak_line>.
look at records--populate it_zpartner
read example
READ TABLE it_vbpa ASSIGNING <it_vbpa_line>
WITH TABLE KEY vbeln = <it_vbak_line>-vbeln.
3) Refer to the field symbol's fields in the loop or after the read.
wa_zpartner-vkorg = <it_vbak_line>-vkorg.
wa_zpartner-vtweg = <it_vbak_line>-vtweg.
wa_zpartner-spart = <it_vbak_line>-spart.
wa_zpartner-kunag = <it_vbak_line>-kunnr.
wa_zpartner-kunwe = <it_vbpa_line>-kunnr.
See the code example below for further detail. The code was written in R/3 4.6C and should work for all 4.x versions.
