User Exit Inactive after transport

hello guys,

i am working on sales order user exit EXIT_SAPMV45A_003. i have done these steps -

1. I have created the Include ZXXVVAU05 in Function module EXIT_SAPMV45_003 and put my code here.

2. Then in the SMOD, in V45A0003 enhancement, i have activate it.

3. Then i have checked the Tcode VA01 and my logic is working fine.

4. Then i moved the TR in quality to test the logic.

But in SMOD of Quality, when i checked the user exit. it is deactivated.

My requirement is that i want to move the changes for DEV to Quality in TR with active version of user exit. So that when i moved to changes in production , no need of to go in SMOD to again Activation.

Guys help me..!!

Thanks and Regards
