Answer 1

Hi, it is not good for your performance to split into 9 selects but the select you are now using is also not so good. Start with VBRP instead of KNA1.
You can do it in the following way. For example:
DATA tb_kna1  TYPE STANDARD TABLE OF kna1.
DATA tb_vbrk  TYPE STANDARD TABLE OF vrbk.
DATA tb_vrbp  TYPE STANDARD TABLE OF vrbp.
Start with VRBP for a better performance
SELECT * FROM vrbp
  INTO CORRESPONDING FIELDS OF TABLE tb_vbrp
  WHERE werks IN ....   etc.
SELECT * FROM vbrk
  INTO CORRESPONDING FIELDS OF TABLE tb_vbrk
  FOR ALL ENTRIES IN tb_vrbp
  WHERE vbeln = tb_vrbp-vbeln.
SELECT * FROM kna1
  INTO CORRESPONDING FIELDS OF TABLE tb_kna1
  FOR ALL ENTRIES IN tb_vrbk
  WHERE kunnr = tb_vrbk-kunnr.
Success.
