Approve button missing for MDG M Workflow

Hello All,

I am trying to set up email notifications for the standard workflow in MDG-M.

I used a standard SAP document attached to work.

Unfortunately, this did not work. So i reverted back all the steps and deleted the BRF+ Z application which calls this step.

And Now my actual standard 86 workflow is also not working. This was working perfectly fine with last status of material as 'Final Check Approved'

I am able to create material, but after refresh 'Approve' or 'Reject' buttons are missing which were visible earlier.

The materials are in 'Changes to be executed' status only.

I am not able to proceed further in approving/rejecting

Please give hints on this.

Thank you,

Shaila.
