Hello there! Could someone help me on this case, I have test suite TS with picked TC1, TC2, TC3 I have data\_set (internal data) with column’s name: C0, C1, C2, C3 TC1 uses data from column C0 and C1, TC2 uses data from column C2 TC3 uses data from column C3 I set value test for data\_set with 3 rows data as this picture: [Imgur: The magic of the Internet](https://imgur.com/a/pWGXo2b) when I run TS, it runs TC1 3 times completely, then TC2 3 times completely, then TC3 3 time completely. So how can I run TS by each row? (run all 3 tcs by row1, then run 3tcs by row2 … so on) (TC1 And TC2 And TC3 with Row1, then TC1 And TC2 And TC3 with row2, and TC1 And TC2 And TC3 with row3) Thank in advance! Tay. ---

I already tried it, but cant, we can run 1 TC with data row by row, but i cant find the way to run some TCs of TS row by row, it run TC1 row by row, then TC2 row by row (not run TC1, TC2 … row by row) Thank for more suggestion! ---

Why don’t create a TC4 which call TC1, TC2 and TC3. Then make a Test Suite with this TC4 and bind it ? ---

HI HeleneB, just tried, i cant find the way to bind data (variable binding) for TS includes a TC which calls some TCs thanks! ---

You have to create all variables from TC 1 to 3 on the TC4. And associate variables when call TC like `WebUI.callTestCase(findTestCase('TC1'), [('TC1_variable1') : TC4_variable1, ('TC1_variable_2') : TC4_variable2], FailureHandling.STOP_ON_FAILURE)` ---

oh, thank you so much after some hours, i can go throw test data row by row, thank again! ah, can i ask you a question, seem this approach is workaround solution. should Katalon has official way to loop data for all TCs from TS row by row, thank! Tay ---
