Thanks for reply,
As SLT is based on ABAP, so we can write complex logic in it.
But if we talk about SAP ECC standard data source, they have complex logic, based on multiple table.
So we need to write code from scratch in SLT to derive same result. but it will be huge time consuming , and required good ABAP skills, also it will lead to bug in code.
Also it will reduce the real time performance of SLT, due to complex logic.
Second option is procedure via SQL script, which is again huge effort in term if logic and can lead to error/bug in logic.
Does we have any other way or architecture to do this is very simple way, with high performance and less error issue.
