SAP Note 28500 - PM order: RAISE_EXCEPTION:"DUMP_NO_ILOAN"

Symptom:

If a PM order is changed from the planning board, it can not be saved. The following error message occurs:
RAISE_EXCEPTION: "DUMP_NO_ILOAN"

Cause and prerequisites

The FORM VB_CHECK_ILOA defined in Include LCOZVFV1 calls the function module GET_ILOA_NUMBER. The function module loses the ILOAN in this case.
Cause: The function module assumes that every order number passed over to the VB_CHECK_ILOA has to be defined in the table ILOA. The ILOA table only contains entries for orders that have been changed. However, the planning table passes over all orders, not just ones that have been changed. In the case of these orders, the GET_ILOA_NUMBER passes back an initialized ILOAN.

Solution
VB_CHECK_ILOA is only called when the order header has been changed, in other words, when the variable VBKZ_TMP has been set.
