SAP Fiori PO Approval Error

Hi All,

Struggling to get to the bottom of this issue when configuring the PO approval for Fiori:

Data Provider implementation 'ZTM_TGW_SVC_MODEL_0001_BE' '01' '/IWPGW/BWF' does not exist

The closest I found that someone who had a related error was this:

I have confirmed that the ALIAS for the GW is pointing to the correct client, in our case 400, additionally ensuring that the tests in SPRO for the alias work and all looks good. Where it gets a little fuzzy is with the gateway service builder mentioned as I cannot see which project I should use or if we should create a new project ourselves relating to the PO approval app.

Any input/suggestions/documentation will be valuable.

Thank you.
