I need to read BSEG table but not using key fields. I have to read it using only company code (BUKRS), purchase order number (EBELN), purchase order item number (EBELP) and material (MATNR) because I need to find the G/L account assigned to this purchase order. I cannot use BSIK/BSAK.
And as you know the performance is very very poor.
Do you have any idea?
