Hi Prasad,
In General, if it is already used for another project, you deactivate that project and you implement new project by using that exit.
Procedure:
1.You have to create a field in the Custom Include of standard table, after creating activate it.
2.Double click on the include then you can add your custom field here.
Find out the Required Enhancements:
1.Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton u2018Information systemu2019.
2.Then mention the particular package name of the transaction you need to enhance. Then you will be shown the list of Enhancement components for that particular package.
3.Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
MM06E005 is the Enhancement component we are using here.
