Techniques are provided for updating a locally stored version of a data set in a multiple-system environment where each system maintains a separate stored version of the data set and is capable of modifying the data set. A data set stored locally in a first application system is modified and a message is generated containing a modification value and the first application system's modified data set. The message is sent to a second application system that also maintains a version of the data set. The second application system compares its locally-stored data set to the data set of the message. Based on the results of the comparison, the second application system either replaces a data value in its locally-stored data set with a data value in the message or adds the modification value in the message to the data value in its data set.
