How "BP Filter" Field is mapped to Test Table (OTA)

Hi,

We are trying to upload automation script using OTA.

But we are getting error "BP Filter field should not be leave blank"

here is the piece of code:

 objTest.Field("TS_NAME")=arr(i)
  objTest.Field("TS_TYPE")="QUICKTEST_TEST"

    objTest.Post

 objTest is the testfactory object

How can we pass "BP Filter " Value?

Thanks,

Manoj
