ME21 ME22 ME28 Can they work with external tax package like Enjoy t-codes?


We are running SAP's ECC 6.0. We recently upgraded our Vertex package to the O Series.

Is there any way to provide data for Vertex via the Old SAP transactions, ME21, ME22 and ME28?

Our solution uses the extension class ZCL_IM_CL_EXTENSION_US_TAXES for method ME_TAXCOM_MEPO to put information into Memory ID's to be received by the user exit ZXFYTU03 which provides data to Vertex. Vertex returns the correct tax for the PO Line Item.

This works fine for the "Enjoy" transactions, ME22N, etc.. However, there are still some transactions, ME21, ME22 and ME28, for example, in which this approach doesn't work. They don't interface to Vertex and return values for the same PO Line Items which are different from the correct ones which Vertex provides.

I was able to get ME22 to work by putting some code in user exit ZXM06U41 that sets up the parameters for method ME_TAXCOM_MEPO and calls it. I have not been able to find a place for t-cdes ME21 or ME28 where I can successfully do this.

Is this something that you have already heard about and address in some way?
