Abstract

A method for determining reversibility of a business function performed by a plurality of development objects in a user'"'"'s system may include determining reversibility of an accessory container object based on a plurality of environmental factors of the user'"'"'s system, checking a set of conditions specific to the business function to determine whether the business function is reversible, and displaying the business function as reversible.

Claims

1. A computer-implemented method for determining reversibility of reversing a business function from a deployed state to a prior undeployed state, the business function being performed by a plurality of development objects in a user'"'"'s system, the method comprising:

determining, by a processor, reversibility of an accessory container object based on a plurality of environmental factors of the user'"'"'s system, the accessory container object being associated with the development objects via a development package containing both the development objects and the accessory container object;

responsive to a determination that the accessory container object is reversible, checking, by the processor, a set of conditions specific to the business function to determine whether the business function is reversible; and

if the business function is reversible, displaying, by the processor, the business function as reversible,

if the business function is not reversible, displaying, by the processor, the business function as irreversible.

2. The method of claim 1, wherein the business function is part of an enhancement package that is selectively activated by a user on the user'"'"'s system.

3. The method of claim 2, wherein the accessory container object includes data entries associated with the business function, and responsive to an activation of the business function, the data entries are extracted from the accessory container object to tables stored on the user'"'"'s system.

4. The method of claim 3, wherein the tables include a configuration table of the user'"'"'s system.

5. The method of claim 3, wherein the data entries are one of updated and deleted after being extracted.

6. The method of claim 3, wherein the determining of the reversibility of the accessory container object further includes:

determining whether the business function is activated;

if the business function is activated, determining whether the accessory container object is linked to an image file for storing a pre-image of the tables to which a content of the accessory container object is extracted;

if the accessory container object is not linked to the image file, displaying the business function as irreversible;

if the accessory container object is linked to the image file, determining the business function as reversible;

if the business function is not activated, determining whether a reversibility patch exists in the user'"'"'s system, wherein the reversibility patch when executed creates the pre-image of the tables to which the accessory container object is extracted;

if the reversibility patch does not exist in the user'"'"'s system, displaying the business function as irreversible;

if the reversibility patch exists, determining the business function as reversible.

7. The method of claim 1, wherein the checking of the set of conditions includes

determining any one of the set of conditions is not met;

if any one of the set of conditions is not met, displaying the business function as irreversible;

otherwise, displaying the business function as reversible.

8. The method of claim 7, wherein the set of conditions includes whether the plurality of development objects that performs the plurality of business functions are transported into a productive system.

9. A machine-readable non-transitory medium stored thereon executable codes that, when executed, perform a method for determining reversing a business function from a deployed state to a prior undeployed state, the business function being performed by a plurality of development objects in a user'"'"'s system, the method comprising:

determining reversibility of an accessory container object assigned to the plurality of development objects based on a plurality of environmental factors of the user'"'"'s system, the accessory container object being associated with the development objects via a development package containing both the development objects and the accessory container object;

responsive to a determination that the accessory container object is reversible, checking a set of conditions specific to the business function to determine whether the business function is reversible;

if the business function is reversible, displaying the business function as reversible,

if the business function is not reversible, displaying the business function as irreversible.

10. The machine-readable medium of claim 9, wherein the business function is part of an enhancement package that is selectively activated by a user on the user'"'"'s system.

11. The machine-readable medium of claim 10, wherein the accessory container object includes data entries associated with the business function, and responsive to an activation of the business function, the data entries are extracted from the accessory container object to tables stored on the user'"'"'s system.

12. The machine-readable medium of claim 11, wherein the tables include a configuration table of the user'"'"'s system.

13. The machine-readable medium of claim 11, wherein the data entries are one of updated and deleted after being extracted.

14. The machine-readable medium of claim 11, wherein the determining of the reversibility of the accessory container object further includes:

determining whether the business function is activated;

if the business function is activated, determining whether the accessory container object is linked to an image file for storing a pre-image of the tables to which a content of the accessory container object is extracted;

if the accessory container object is not linked to the image file, displaying the business function as irreversible;

if the accessory container object is linked to the image file, determining the business function as reversible;

if the business function is not activated, determining whether a reversibility patch exists in the user'"'"'s system, wherein the reversibility patch when executed creates the pre-image of the tables to which the accessory container object is extracted;

if the reversibility patch does not exist in the user'"'"'s system, displaying the business function as irreversible;

if the reversibility patch exists, determining the business function as reversible.

15. The machine-readable medium of claim 9, wherein the checking of the set of conditions includes

determining any one of the set of conditions is not met;

if any one of the set of conditions is not met, displaying the business function as irreversible;

otherwise, displaying the business function as reversible.

16. The machine-readable medium of claim 15, wherein the set of conditions includes whether the plurality of development objects that performs the plurality of business functions are transported into a productive system.
