Described herein is a system and method for propagating modifications in flows. In an embodiment, a central system activates a master process (e.g., master flow), including a sub-process (e.g., sub-flow) and a pre-programmed object (e.g., component). The master process is configured to execute a task using the sub-process and pre-programmed object. The central system initializes a variable corresponding to the master process. The central system further identifies a metadata object using the variable. The metadata object defines a runtime configuration of the master process and sub-process. The central system receives a modification to a setting of the metadata object and propagates the modification of setting in the metadata object to the master process and sub-process.
