Need to delete Inactive Transformations in Prod Sys

HI Experts,

We have two transformations in PRD Sys between same source(DS) & target (DSO).

Reason: While transporting transformations first time we miss the sequence, so that the transformation in prod system referring QA System(Wrong). Later we transported in correct sequence, now its referring PRD system.

Req: Now we need to delete transformation which is referring wrong client(QA).

        We also referred SAP Note 1240905, but its not working for us.

        And we also tried to delete by opening client . But it's asking TR.

        Note: Source system mappings are fine.

Below is the screen shot for your reference. Please let me know how to resolve this.

QTLCLNT400(QA), SOTL400(PRD)
