Error: Function Module FORM "BDC_DYNPRO" does not exist”

Dear all

I created my First BDC from TCODE: SHDB on my testing environment server.

From this BDC I created my function Module, everything is working very well.

Now I moved my BDC to our DEV server to be moved to QAS server later.

On the DEV server from this BDC I created my function Module.

When I try to activate it I face this error: “FORM "BDC_DYNPRO" does not exist”

“perform bdc_dynpro      using 'SAPLSPO4' '0300'.”

I need help.

Thanks,
