No approver was found to approve your journal batch

Dears,

When you create an independent journal, a journal batch is automatically created for it, which then goes for approval. However, if you manually create a journal batch and add journals to it, the batch does not go for approval. We are encountering an issue where no approver is found to approve the journal batch.

Why does a default batch created for a journal go for approval, while an explicitly created batch does not? We are using AME rules for GL Journal Approval.

Thanks,

Venkat
