Bottom to top approach:
step 1:
creating a domain:

Step3:
Creating a table;
Se11,select the object type as table,name it, create,
Enter the field name and assign it with the data element instead of assigning a datatype to it,
Like this create req fields:
On behalf of this:
Table maintainence:
Assign the type of the table ie.,A C G L S
NEXT
Maintaince:
allowed,not allowed ,allowed with restricions
