How to compare Migrated Transformation to 3.x Update/Transfer rules

Hi,

I am recently migrated 3.5 UR and TR to 7.3 Transformations. Now, I need to compare both versions transfer rules/Update rules to Transformations.

I know the ABAP code also will be migrated accordingly. But do we have any simple comparison mechanisam instead of comparing one by one opening in two different screens.

Thanks in advance.

Regards,

Sai

    Hi Sai,

    Lets load selective 10 records to target in two methods(3/x/7.x) and see the out from target.

    whether it shows same data or different one.

    if its different then find the field/object which have different data and dig at transformations mappings to specific object.

    Thanks

    • if all you have are 1-1 mappings, than random testing would be an option (still not a safe one, but at least an option)

      in case you don't have all 1-1 mappings (like 95% of the BW projects out there), you may want to spend quite some time in checking each and every flow

    Hi Sai

    Although both 3.5 flow and 7.3 flow sits in the same system, both uses different methodologies to transform the data which you are aware of.

    Hence we do not have a specific method to compare both. But if you haven't got any error during migration, it shows that the migration went well and there is no issues.

    In few cases, some complex routines might not be migrated properly and it will throw error during that phase. If you haven't got any error, I think the migration went well and its all good now

    If you still have doubts, no need to check all the fields as you might have many. Just choose one per rule type. like choose one field which has field routine and compare. choose one field from formulae and compare.

    If you have encountered any issues, please post here, we will analyse and help you to resolve it

    Hi,

    There is no simple way to do that I know, also may not be direct answer to your question.

    1. Copy the code into notepad and use compare tool (for example ultra edit)

    2. In window system you can open two windows side to compare ? If this is an option

    3. Why to compare the code..Test the result by means of unit test and regression test with both before and after image ?

    Thanks,
