Which of the following can result in an overflow error during calculations in ABAP?

An overflow error in ABAP occurs when a calculation exceeds the storage capacity defined for a variable or data type. Each of the scenarios listed can independently cause such an overflow error.

Using large integers can lead to overflow when the result of a calculation exceeds the maximum size that an integer variable can hold. For example, if you perform operations on two very large integers, the result could exceed the limits of the integer type, thereby causing an overflow.

Dividing by zero is another critical scenario, though it might not directly relate to overflow in the traditional sense. Instead, it results in an error during execution, halting the program. While this doesn't typically cause an overflow error, it represents an invalid operation that must be handled to prevent runtime errors.

Exceeding the DECIMALS limit in fixed-point decimal arithmetic can cause overflow as well. When the result of a calculation goes beyond the predefined decimal places of a variable, it can result in errors, including overflow scenarios, because the data cannot be accurately represented within the specified limitations.

Since all of these conditions can lead to errors in calculations, encompassing overflow errors and other types of operational failures, it is correct to say that all of the provided scenarios are valid reasons that can lead to some form of computation error
