2668839 - Approve Button is Disabled or Grayed Out on Supplier Invoice Approval Task

The user is unable to approve Supplier Invoice via Task. Hence the user needs a workaround to be able to process the Invoice.

SAP Business ByDesign

1. Go to Managing my Area work center. 
2. Go to Approvals View. 
3. Select the task regarding the approval of the Supplier Invoice ABC (ABC is the Invoice's ID). 

The Approve button is grayed out.

After the Supplier Invoice was submitted for approval, some changes were made that affected the posting of the Supplier Invoice. Hence the system no longer allows the user to approve this Invoice.

There is a workaround in which the user can withdraw the Supplier Invoice from approval via front end: 

1. Go to Supplier Invoicing work center. 
2. Go to Invoices and Credit memos view. 
3. Search for ABC. 
4. Click in Actions button and select Withdraw from approval.

The invoice will [1] no longer have In Approval status (it will change to its previous status) or [2] trigger error messages indicating what the user has to correct in the invoice.
