solving from SAP:
"Function Z_LOMF_GET_HU_INFO call Z_PLO_BATCH_CHARACT_GET an in this
function the non release function VB_BATCH_GET_DETAIL is called, which
is calling CLAP_DDB_INIT_CLASSIFICATION. This causes the issue.
Function VB_BATCH_GET_DETAIL is not release so it's not allowed to
use in customer own functions, see note 109533 and 415983.
Please deactivate Z_LOMF_GET_HU_INFO and test again"
