HI There,
It’s hard to predict the reason without debugging the code :)
But I saw few possible reasons that can cause the issue in IFS codebase.
Issue can happen due to several things in the code of Cust_Order_Customer_API
Several parts were fixed by ifs in these versions - 24R1 GA, 24R2 EA, 23R2 SU6 ( found this on KB0056204)
But one of my colleagues found out a missed correction even after 24R1 which is in Check_Update___ method .and we are going to report it to IFS
If you are SU4 or SU5 , Try to get to SU6 , If the issue permits most probably you have the same issue as us .
@Chamaka Wimalarathne thank you for the update!
