Hi Folks,
I am working on a MAK customization on OIS390 (Customer return program).
The requirement is to add a new column Received date in OIS390/B1 for Sorting order 1 which should display minimum return date from all the order lines of that particular receiving number.
I have made changes in OIS390 View Def OIS390BS to introduce new field S1RCVD (Received date) for sorting order 61 inside IN61.
I have also created a new CUS component of OIS390 (It was there in MVX only) to modify PBMSF to get minimum return date from OIS391.
The changes are deployed to Hfix.
Now, when I run OIS390, initially it shows correctly the values in newly added column Received Date but as soon as I use any option like Display/Lines etc, it generates dumplog.

The above dumplog appears when this code is executed for line 2129 in PBCHK of OIS390 (MVX)

Kindly help.
