Hello Sam
- It is considered to be the basics of using a user-exit.
- First the system is asking a package --> Means if you are testing this user-exit you should give value $TMP or if you are working seriously then you should give a Z-package such as ZPM (usually used for Plant Maintenance related developments).
- In case you select a Z-package system understands that this wotk will be taken to other clients (QAS and PRD) , So it is asking you to enter the already created Transport request, if you have any by clicking on 'Own requests' . IF it is not the case then you need to create a TrReq by clicking on New icon.
- This is true with any user-exit. You should also know that user-exits do not function unless they are assigned in the Enhancement list of a project created by you through tcode CMOD.
