sending a first block command for a master data object to each application in a set of multiple applications in a multiple-application landscape, wherein the multiple-application landscape includes a master data distribution application that is separate from the applications in the set of multiple applications;

receiving a first blocking status from each application in the set of multiple applications, wherein a respective first blocking status for a respective application indicates whether the application successfully blocked the master data object in response to the first block command;

determining a first overall blocking status based on the first blocking statuses received from the applications in the set of multiple applications;

determining, based on the first overall blocking status, that at least one application failed to successfully block the master data object;

in response to determining that at least one application failed to block the master data object, sending an unblock command to each application in the set of multiple applications;

receiving an unblocking status from each application in the set of multiple applications, wherein a respective unblocking status for a respective application indicates whether the application successfully unblocked the master data object in response to the unblock command;

determining an overall unblocking status based on the unblocking statuses received from the applications in the set of multiple applications;

determining, based on the overall unblocking status, that at least one application failed to unblock the master data object; and

in response to determining that at least one application failed to unblock the master data object, sending a redistribution request to the master data distribution application requesting the master data distribution application to redistribute the master data object to applications that failed to unblock the master data object.
