I have made a simple infoset in SQ02 with billing document header table VBRK and item VBRP. In item table I have VBRP-VOLUM which displays item volume.
The task is to get total volume per invoice VBRK-VBELN
To get total volume per invoice I can simply use subtotals functions directly in SQ01 queary, but instead I want to :
1) add aditional field in infoset - this I can do it through infoset extras -ok
2) in code section for this field whrite abap code that would calculate total sum of VBRP-VOLUM per invoice. Here I need help - what codes lines should I enter ?
probably this simple code but I am not Abaper so ask for help 😊
