Hello Jaime,
If the assets were migrated with the Master data (like in your case with wrong class) then it will not be possible to correct/Change values.
You will need to reverse the migration and perform migration again with the correct data.
As seen in the screenshot, Reverse migration button is grayed out.
This could be due to the reason that you don't have valid process control for the Migration posting date.
Please check following and adjust accordingly.
1) General ledger work center
2) Select Companies view
3) Select the row with the company
-Note the Posting date for Migration.
4) Click on Set process control
5) Show : relevant for today
- There should be an entry similar to below
Process control status : Not blocked
Business process group : 09 - Migration
Entry Possible until : today or in future
From Posting date :
To Posting date :
The period of the From Posting Date / To Posting Date always refers to the posting date(In this case posting date for migration noted in step 3). So Migration posting date should be in between From posting date and to posting date.
I am assuming that this process control entry does not exist and hence reverse migration button is not enabled.
Please maintain process control entry and then check.
Let me know if this works.
Regards,
Harshal
