I have configured the Interaction History Profiles through IMG --> CRM --> IC WebClient --> Master Data --> Define Interaction History Profiles. In the profile, I added transaction type TA along with other custom transaction types. The new profile was assigned to the functional profile on the business role. However, I am unable to see any sales order history in the interaction history (but am able to see the other custom transaction types).
I made similar configuration changes to the account fact sheet. Here I followed instructions from this blog: http://sites.google.com/site/rupeshpatil/tweets/addsalesordertoaccountfactsheet . I used transaction type TA for the search display. The account fact sheet is able to retrieve the ECC sales orders without any problems.
I am also having the same issue with agent inbox search for sales orders, but this is not as critical.
The ERP Sales Order Profiles have also been set up to use the ECC client with document types OR and TA, and have been assigned to the functional profile on the business role. IMG --> CRM --> IC WebClient --> Business Transaction --> ERP Sales Order --> Define Profiles for Sales Order
