Hi ,
Greetings !!!
There is an ambiguity between the name of these two .
When i refer to SAP LT it's https://support.sap.com/solution-manager/integrated-tools/lt-software.html or https://support.sap.com/content/dam/library/SAP%20Support%20Portal/support-programs-services/solution-manager/integrated-tools/Integrated%20Solutions/Media%20Library/SAP%20LT%202.0%20software%20-%20Overview.pdf.
1) Both Seems to refer to similar task . Are these both from same product line with different naming convention ?
2) Any notes/document which refer to similarity /difference between these two will be very helpful .
Thanks in Advance
