Activating the enhancement M61X0001

Hi,

I want to use the enhancement M61X0001 for MRP controller wise planning for the transaction MD01.

I have written the code in both the includes (ZXM61U02,ZXM61U01) of 2 FMs EXIT_SAPLM61C_001 & EXIT_SAPMM61X_001.After activating the enhancement through the project the desired effect is not showing.

If I put breakpoint in the coding of the includes of FMs program doesn't stop at the breakpoint.

When I checked the include for functional module it is not there in the standard program of MD01.

What might be the reason??

Do i need to activate the enhancement in some different way??

Thanks,

Manas.
