Expense custom validation

[mmiao]

Hi, 

We have a requirement where we need to validate the expenses to see if They match with the receipts in value and description, and we need to check if the receipt has words like beverage, etc.

It is not enoght to use the validation rules, we want to build a side-by-side extension in SAP BTP, does anyone knows if there is an syncronos business event that I can use to rook my custom validation?

In case everything is fine the validation routine should change the status of the report to move forward to approval.

Anyone had a similar requirement?

Regards

Mauricio

@mmiao I've not heard of anything like this. For a report to move forward in the approval process, it usually needs someone to review the report and move it forward, one of our Audit Services to review and move forward or a skip step, which looks at elements of the report, not receipts. 

Maybe someone else has done something like what you are asking, but I've not come across it in all my years here at SAP Concur.
