Reg Logical System Name

[Former Member]

Hi,

We have ECC 6.0 PROD and ECC 6.0 QAS System.

WE have different logical system names for both the systems

But when we refreshed the PROD to QAS , we have to run the BDLS transcation to change the logical System name(since we are having different logical System name)

But BDLs is taking more than 40 hours.

Please let me know , whether logical system name can be the same throughtout the landscape or not

In other words , is there any side effects if i have same logical system name for QAS and PROD

A logical system is a unique client identifier in within a system. Its important to have properly establish logical systems as they are the base of communication in between systems and ALE.

You can define and assign a new logical system after the system copy via transaction SALE -> Basic settings ->Logical systems -> You'll see options Define and Assign logical systems there.

Hi,

Do you mean to say that, After a system copy , create a new logical system and assign the logical system to the client

If i do so , will get all the data in production to QAS correctly

Please guide

You can try to do it directly after your refresh... just change the logical system to the one that QA used to have before the refresh.

It might help you.

PS. Also as far as i know you're suppose to run BDLS at a quiet time and it's mean to take quite a bit of time depending on the size of your DB.

Hi,

Please confirm whether i will get all data correctly without doing a DBLS

I can't confirm that... you might aswell try it!

I've been researching the same issue. I found the following

"Is it necessary to change the logical system names?

Because of the two reasons mentioned above (long runtime of transaction BDLS and possible inconsistencies), it may be desirable, to avoid the renaming of logical systems during system copy.

Whether logical systems names need to be changed at all after a system copy depends on the type of the target system: "

Hope this helps. I'm continuing my search.
