Unfortunately there is no way to call OP only.
Read the following documentation.
Maybe you can use some of the following options. e.g.(with prompt for DS and PO.)
1. Launch a Report - Without Prompting for Version
function runE1UBEBlind(ubeId, version, promptPO)
Required Parameters:
ubeId = E1 UBE Name, for example R04305
report version = E1 Application Version, for example XJDE0001
e.g., javascript:runE1UBEBlind('R31410','XJDE0001','0')
Note that it is no possible to launch a report that just prompt for PO, use task with E1 Page Generator.
2. Launch an UBE with prompt for
DS and PO.
function runE1UBE('RXXXXP', 'promptForDS', 'ZJDE0001', '1')
3. Launch an UBE and get data selection but no processing options
function runE1UBE('RXXXXP', 'promptForDS', 'ZJDE0001', '') or function runE1UBE('RXXXXP', 'promptForDS', 'ZJDE0001', '0')
The only option you have left is:
@c:color=red|reportId=R550901|version=LIS0008:WSB Income Statement:runE1UBEVersion('R550901','promptForDS','LIS0008','1')
I recommend upgrading to TR9.1.3.
