I am working on CRM4.0.I am trying to use CRM_ORDER_MAINTIAN function module for writing an interface which updates the activity record in SAP CRM. We have added some customer fields to activity using easy enhancement workbench. Also this interface needs to change dates in appointments tab and add long texts. Can anyone help in this regards or give me a sample code to do it.
I could only successful in updating/changing the header fields(such as description, etc) so far.
