I could not see modification in this program LVHUPOF16, however I will get it checked also with programmer.
Below are some finding related to note2118783 in program LVHUPOF11
SAP have made change in this Note by removing the statement
PIPO_ROW_COMPONENT. and
exchanged the check to look at the variable matnr. instead
we have recently support pack-
SAP_APPL 617 0008 SAPKH61708 Logistics and Accounting
Could it be related to this behavior change?
