User exit not triggering

Hi All,

I would like to Modify the BASIC IDOC SHPMNT05 with message type Z**, before it is sent

For this, I found a enhancement V55K0020 which calls the FM EXIT_SAPLV55K_020

I created a Z project in CMOD and assign the enhancement & component etc and activated the project

Now to test this, I put break point in code and FM and trigger the idoc via VT02N change - go to output & repeat output

IDOC is getting generated but it is not stopping at CMOD or Break point.

Any idea how to handle this.

Thxs
