SLA on Invoice Line Flexfield for Project Segment

Summary:

We have the requirement where during accounting Project Segment value should be the value populated in Invoice Line Flexfield Attribute 1

Content (please ensure you mask any confidential information):

We have defined a DFF at Invoice Line. DFF value set is based on Project Segment values from Chart of Accounts. We have created the mapping sets, attached it to Account Rule and the also did the relevant SLA Setups. However, during "Create Accounting", system is not able to fetch the value of DFF and hence system uses the constant for Project Segment which we defined as part of SLA rule.
