Yummy FM for reading IS-U Master Data

You can get every possible data using just one function module called ISU_STRUCTURE_READ. The trick is, you have to place the table connections into tables parameter XT_PATH and fill the corresponding "kick-off" table parameter. Let's have an example. We want to have contract account, contract (billable service), and installation data to a specified BP.
data: xt_path type EFKKPATH occurs 0 with header line,
      iekun TYPE line of ISU01_EKUN_TAB occurs 0 with header line,
      ifkkvkp like FKKVKP1 occurs 0 with header line,
      iever like ever occurs 0 with header line,
      ieanl like v_eanl occurs 0 with header line.

refresh xt_path.

xt_path-tabfrom = 'EKUN'. xt_path-tabto = 'FKKVKP'.
append xt_path.
xt_path-tabfrom = 'FKKVKP'. xt_path-tabto = 'EVER'.
append xt_path.
xt_path-tabfrom = 'EVER'. xt_path-tabto = 'EANL'.
append xt_path.

iekun-partner = your business partner.
append iekun.

CALL FUNCTION 'ISU_STRUCTURE_READ'
  EXPORTING
    X_AB = sy-datum
    X_BIS = sy-datum
  TABLES
    XT_PATH = xt_path
    T_EANL = ieanl
    T_EKUN = iekun
    T_EVER = iever
    T_FKKVKP = ifkkvkp
  EXCEPTIONS
    PATH_INVALID = 1
    DATE_INVALID = 2
    SELECTION_FAILED = 3
    OTHERS = 4.
Table connections also work the other way (e.g. from installation to BP). Check the possible connections in the source code of the FM. Form INIT_ALL, lines starting with MAC_LINK_APP.
