Hi Vineet,
When you see the Transfer order in LT22 or LT24, do you see the deletion indicator set against the Transfer order? If you do not see that deletion indicator after deleting it in LT15, please try to check if any short dumps were created in in ST22 by deleting the TO once again. If you get short dumps, then it may give some inputs. Based on your feedback we may try to find some other options.
Thanks,
Raghavan
