Dynamic Action is not evaluating field correctly. Triggers all the time instead of when field value changes

We are using ECC Ehp6,

I've probably tried 20 different attempts using 00, 04, 06 along with the comparison of the

P P0171-BSTAT<>PSPAR-BSTAT or

P P0171-BSTAT<>PSAVE-BSTAT,

P PSPAR-BSTAT<>PSAVE-BSTAT,

BSTAT in "field" then I INS,0378,MSC,,(P0171-BEGDA),(P0171-ENDDA)

nothing works for me.

I even tryed to configure for 0171 to create only if P0001-WERKS or P0001-ANSVH change but instead it triggers every time - no matter if the values change or not.

00 P P0001-WERKS<>PSAVE-WERKS /X

00 P P0001-ANSCVH<>PSAVE-ANSVH /X

00 I INS,0171,,,(P0001-BEGDA),(P0001-ENDDA)

There is so much standard delivered logic out there with these codes very similar, I expect it to work but no. Would someone please reply with the code that would work?
