What is the step by step process to create a table in data dictionary?
steps to create database tables
1.go to se11
2.give name the database table
3.give short description for the table
4.Give delivery class name as A and data browser / table view maint as Display/maintenence allowed
5.select fields tab
6.give field name data type(user defined element type/built-in-type),short text
7.select technical settings tab ,give data class as appl0 and size category as 0
9.go utillities menu click table contents select create and enter the field values then select display in table contents and u can view the table values with field lables
bottom to top approach:
creating a domain:
*se11,select the object type as domain ,name it ,create,description,enter the datatype and length(size),save ,activate
creating a dataelement;
se11,select the object type as :date element,name it ,create,desc,assign it with a domain what we created now,save,activate it.
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:
assign the type of the table ie.,A C G L S
allowed,not allowed ,allowed with restricions
fields of a table:(as descripted above)
BUFFERED OR NON-BUFFERED
