Time Card is not using the Rate Model and is instead using the Default RateIssue When submitting Time Cards you are seeing that the generated Expense Lines are using the Default Rate ($50) instead of the Rate which is set by the Rate Lines inside the Rate Model which is related to the Project.CauseIf you have validated that the conditions for the Rate Line are being met by the Time Card, then this issue is potentially happening because of the Time Card Preferences which are set on the Project which you are submitting the Time Card for. Specifically if you are submitting the Time Card on a Sub-Project and the Top Task 'Project' has the Time Card Preference set to 'Project Task Only' then it means the Rate Model will not be getting picked up. This is happening because the "Check if time cards allowed" Business Rule is seeing that the Time Card Preference for the Top Project and is then aborting the Rate Model Calculation, since it sees that the Sub-Project does not meet the criteria for the Time Card Preferences. This is the current expected behaviour of the system.ResolutionThe recommended resolution for this issue is to set the Top Task Project so that it has the Time Card Preference of Project & Project Task. However, another alternative would be to customise the "Check if time cards allowed" Business Rule so that it is getting the Time Card Preference of the Sub Tree Root instead of the Top Task. This is not recommended since it is counted as a customisation and could potentially cause unexpected issues. Lastly, we would also suggest that you Raise an Enhancement Request on the Ideas Portal if this is a Use Case which you would like to see implemented into the product as part of one of the future releases.
