We have downloaded condition type from ECC, the condition type doesn't have any access sequence and it is also marked as Manual in Pricing procedure.
At the time of creating a transaction in CRM, I am able to add condition type in Price details, but not able to maintain any value. I tried similar creation of transaction in GUI environment and was able to maintain value against the same condition type. Now I open the same transaction ID in Web UI, the value is displayed, but still not editable.
Please let me know, if you need any further information.
