Question about accessing TPA data on TN using IS developerwebMethods 601

Hi,

I am creating a TPA on TN. Now when i am accessing this TPA data in IS developer using wm.tn.tpa:getTPA, it gives an error saying that the specified TPA does not exist.
If i use createTPA on developer and create the TPA, then i am able to use getTPA to get the TPA data. But now, this TPA details are not shown on TN.
Could anyone explain why this is happening?

Thank you,

Shiva
