Drill Down not Working in FMDERIVE

Dear All

My issue is like this. In FMDERIVE, I am able to maintain the derivation strategy. However not able to maintain the derivation rule and its value, since the drill down functionality is not working on double clicking the relevant derivation strategy. The system details is also as follows:

Component           Support Package

SAP_APPL           SAPKH60024   Logistic and Accounting

  EA-PS                     SAPKGPPD06     SAP Enterprise Extension - PS

Thanks and Regards
