Updating default value of new column in SAP system
It is not good practice to update default values to a column as this will not be visible directly in the system and will not be picked by CTS. Also, there is no option in the SAP/ABAP environment of adding default values to the table column. If you choose to make the new column have NON-NULL values, you will have to manually update default values and it will take a lot of time to modify the table. The best way is to choose your default value as spaces, zeroes and so on depending upon the type of column.

Read MoreStoring Personal Information in LDAP/AD or in SAP HR module
LDAP can store sensitive information but it is not recommended to store sensitive information in LDAP from a security point of view. This information should go to some HR information or you can also develop a middleware to store this information. You can use EMP ID to track this information back to middleware or LDAP.
Read MoreHandling higher level Boolean values in SAP system
As per the general standards and coding practice, you should use abap_bool for handling Boolean value or truth values. In this case, if any object is declared as abap_bool type, then it can hold values only from the set (abap_truth, abap_false and abap_undefined). But in older systems, you might not be able to use abap_bool as it is not available. For ex. In Web Dynpro abap_bool is not available.You need to use WDY_BOOLEAN as an alternative in this case. WDY_BOOLEAN only allows true Boolean values meaning it allows only true and false as permissible values but not undefined.
Read MoreSAP Authorization concept and Authorization Objects, Object Class
To clear the air all at once, SAP Authorization Objects and Object Class has nothing much in common from Object Oriented classes and objects and differ vastly from it.Authorization object details the current user’s privileges which are used to authorize user activities and data availability. The Authorization Object is the place where configurations pertaining to permissions are set up and initialized against fields.An object class, on the other hand, is a grouping of Authorization objects. It may contain one or more than one authorization objects.
Read MoreComparing SAP ABAP Field symbols and data reference with Pointers in C
Field symbol resembles pointer in C but there is one main difference: you can use Field Symbol only to access the values present in it but not the memory address. Similar to a pointer in actual, it stores the memory address of the variable that was assigned to it. You can see the data held by the variable but you cannot fetch the memory address. Similar to a pointer, in case if you make changes to data referenced by field symbol, it changes the value at the original place too. Data reference too resembles pointer at a high level. You ...
Read MoreReferences are not allowed in a SAP remote function call
You are trying to make use of references but you should be aware that it is accessible only with the same stack and in your case, it is not. You are creating a remote function module and here references will not work. So, you should be going with parameters as ‘pass by value’ instead of ‘pass by reference’.
Read MoreUsing AT_FIRST be used to initialize variables used in loop in SAP ABAP\\\\\\\\n
There would not be much of difference in both ways. The only thing is without AT_FIRST, the counter variables will be cleared in all cases while using AT_FIRST, the counter variables will be cleared only if there is at least one execution of the loop. So, the only difference would come into the picture if ls_itab is empty.
Read MoreI don’t want configuration information to be transferred with the database in SAP ABAP
The straight answer to this is a big NO. This is one of the most common places of error in the SAP environment. When you create a clone of your production in the form of QA with most of the things as it is from production, you need to make sure that any action in QA after cloning doesn’t have any implication or effect on actual production.To handle such a use case, you need to rely on SAP transport and Change management. You need to use the provided transports to alter the existing configurations to QA.
