ESS/MSS - Error " 404, The requested resource is not available."

Hi

I have deployed below archives in the EP 7.0 SP14 system. My back end system is ECC 6.0 with SP14.

1)BP ERP05 ESS 1.0 with sp14

2)BP ERP05 MSS 1.0 with sp14

3)SAP ESS 600 with sp14

4)SAP MSS 600 with sp14

5)SAP PCUI_GP 600 with sp14

We are getting " The requested resource is not available." error after clicking on

Working Time tab.

Can anyone suggest me whether i need to update any higher level patches from EP and ERP side ?

Or what could be the problem ?

Thanks in Advance,

Vinay
