GL accounts mapped to ALE Account

Hello Team,

We need to find out how many GL accounts are mapped to an ALE account.

For EX:

980 is an ALE account maintained in syatem1 .  Some  transactions from system2 will be hitting To this ALE account, on daily basis.

Now we are facing some mismatches in the 980 - ALE  account in system1.

So we would like to what are al the GL accounts mapped to this ALE maintained account.

Is there any Tcode or table to find out this mapping ?

Thank you.
