Hello Antonio,
Please check :
1) Business configuration activity: Business Task Management for Payment and Liquidity Management
Here you can define the threshold amounts and the approvals tasks for the payments.
- Either untick the task which is not required, or maintain the high threshold values
Also check : Application user management -> Employee work distribution -> Approver for Liquidity Management for the approver determinations.
I hope this will answer to your concerns. Let me know if you need further details.
Regards,
Harshal
