| Wait until last transformation of another table is calculated. | \\ |
| | =====Description===== |
| | This action pauses the current action chain until the last action of another table is calculated.\\ |
| |
| This transformation is usually used for synchronization of access to external files and applications in order to avoid simultaneous reading/writing by independent transformation chains. In a typical use case it is inserted immediately before a side-effect transformation (export, run program, etc.). As EasyMorph calculates independent transformation chains asynchronously, Synchronize is used to enforce a dependency and guarantee a particular execution order. | \\ |

| | |Other table|Select the other table to synchronize with (e.g., wait until that table's action chain is complete before continuing the current one).| |

| | \\ |
| | =====Remarks===== |
| | You cannot select a table that relies on (is based on) the current dataset. Doing so will result in a "cyclical dependency error". |
