Transaction Key ANL is not a Control Account - Error

Hello Experts,

I am getting below error while posting a GR, Message No M7114  Transaction Key ANL is not a Control Account.

The GL account referred in the error is already defined as a control account   Reconciliation as " A ".

However one  strange thing that my company code is not visible in OAMK so I am not sure whether it is relating to the same ?

Despite this account is defined as Reconciliation Account why system is throwing an error ?

Experts guidance will be appreciated on this.

Also can some one please tell me why the account key ANL is used and when ? Because I tried searching it on market place and SDN but no luck.

Regards,

Sharvari Joshi.
