External tax calculation PO (ME23n)


Hello All,

I am not sure if this post needs to be moved to MM. However I am a ABAP developer and looking for an option in terms of code change also and so posting here.

For out use client we are calling SABRIX to calculate tax. We are facing issue when accessing the POs via ME23n. When calling Sabrix along with available fields we are also using custom fields via a customer exit (such as order, cost centre etc, material group, purchasing group etc.).

Details of the issue:

There are few older POs when we go in ME23n and conditions it is showing some calculated tax, let's say 7%. While issuing output also (print preview) 7% tax appears (stored in EKPO). On clicking tax in invoice tab SAP is calling Sabrix with the tax date same as PO date with other fields. For some reason tax is being returned as 0%. After this if you come back to conditions tab again the tax disappears. But print preview shows the tax (from EKPO). This is misguiding the users.

It is obvious that when the PO was created/ changed earlier there was a tax calculated but not now. Even any change in tax should not take effect here as we care calling Sabrix with old date.

Am I missing something here? Is there any way I can display the old original tax .

Your help much appreciated. Thanks,
