In my other post Using Direct Page Links for Formsand Dashboards in PBCS!!! We used the POV with hardcoded members for accessing
the forms. A anonymous comment on the post asked
So thought of posting on Using the Direct Page
Links for forms using substantiation Variables.
In the POV call the Substitution variables as “&SubVar” instead of the actual member.
https://demo-test-demo.pbcs.us2.oraclecloud.com/HyperionPlanning/faces/LogOn?
Direct=True&ObjectType=FORM&ObjectName=ForHeadCountExt&POV="&FcstStartMth","&ActCurYr"
And the Forms is called using the sub var
Hope this helps !!!
