Hello SAP experts,
In MDG, M- We have to create the material number based on line of business with prefix and suffix some thing. e.g. E123456700 (E is LOB and 00 are appended in the last)
so for achieving this , we have modified the UI screen and also have the necessary custom UI fields in the UI.
1. New/ Variant radio button select
2. Give Line of business as drop down and proceed for create material.
Now , when a user is entering the data in this custom UI elements, how can we grab/store this UI elements e.g. map the UI elements to the user exit MGA00002 for MM01 transaction to derive the external material number .
In WDA, we generally use Context mapping, will context mapping work and if it works, how and to which to i context map my custom elements.
