Argentina official document number range (Changing of XBLNR)

Question

Hi All,
Working on a typical requirement.
As some of you are aware, the official document number (XBLNR) is getting generated by system based on branch, document type, document class and print character.
Is there any posibility to change this value before the Accounting document is going to be created(after I press save)?
Is there any userexits/BADIs/BTEs that will trigger before this official document number is going to be generated, so that I can change XBLNR value?
Does anybody had encounter such situation? if so please let me know.
Appreciate your help on this.
Regards,
Nanda.

Next to substitution (tx OBBH) you can use Program LXVVFU01  User Exit AC Interface (Header Line).
function module EXIT_SAPLV60B_001:

        XACCIT-BLART = 'RV'.
      when others.
    endcase.
    xaccit-xblnr = xaccit-xblnr+0(16)
  endif.
Via customizing (cross applications Cross-Application Components / General Application Functions /  Cross-Application Document Numbering ´/  Argentina  ) you can set up the document numbering.
Hope this helps!
