Hi Dharmakasi,
Yes, I assigned date profile ZSER00000001 to the related transaction type, if I use this bol entity BTDate_T_ORDERPLANNED, only today's date is saved and displayed. If I use another bol entity BTDate_T_ZS_NEXT_PERC, the value in field End Date will be cleared, no value is stored in table after running crm_order_read program as you said.
If I remove this date profile, value is cleared as well.
BTDate has some rule definitions, so now I choose another bol entity //BTCUSTOMERH/STRUCT.ZCONS_DOE, it works well now, thanks for your reply.
Kind Regards
Andie
