Posting Error during MIGO: G/L account blocked for posting for company code

hi.,

I am getting the following error while positing in MIGO

<b>" GL account xxxxxx blocked for posting in company code xxxx"</b>

I have checked the GL account thru FS00. The GL account is present.

In FS00, for the G/L account, i know there is a a Tab to block the G/L account, but how to find the tab to un-block the G/L account.

How do i un-block the GL account?

Tx
