Hey Toy,
the problem probably comes from incompatible UI Versions.
Since BPC 10.1 has built on HTML5 Basis, SAP UI components can have a strong Impact on the BPC coding. Please look at the link below to solve your issue. I assume that your SAP UI Version SP09 is incompatible to SAP BPC 10.1 SP02. Try to downgrade to SP08 and it will work.
Hope, this will help you,
Karsten
