Hi Vinjay,
Did you create a new model for Entry and Approval or a new model connection i.e. JUICE1PBI?
You do not need to create a new model for Entry & APproval. You can use JUICE1PBI and in BICA ensure that the Target metric is set to "Create New" instead of a measure from BW.
Please try this and post screenshots of the errors that you are experiencing.
Hope this helps.
Kind Regards,
Zimkhita
