APP-FND-01238: Cannot set value for field :AC_ITEM.
APP-FND-01618: Column :AC_ITEM_NUM_PSEG not found
Could you help in this..
We saw patch in Oracle note 1519492.1 but not sure what thay actually did to solve the issue?
The suggested note refer to a different field from yours even though the issue is of similar type. Anyways reading the CAUSE section will help you understand the issue and might help the development team to find a workaround.
If not the best approach would be is to raise an SR for these cases.
