Post non PO invoice line items using INVOIC01 and FM IDOC_INPUT_INVOIC_MRM

Question

hello there SAP folks,
Have an interesting question for all of you. We currently have a partner through whom we use the IDOC_INPUT_INVOIC_MRM Function module to pass invoices. Now there are multiple line items some times [multi E1EDP01 / E1EDP02] segments which all refer to the same PO but to different line items on the PO. Now all that is well.
For one particular partner we now have the following requirement. We are going to have the same condition as above, with the added condition that there are going to be some invoice line items with no reference to a PO. the reason is that the vendor is going to calculate the different taxes and send them to us. so when we post the invoice :
we will now have
31 Vendor
40 GR/IR
40 Tax 1
40 Tax 2
50 Tax 3 offset
instead of
31 vendor
40 GR/IR
to deal with the new situation I tried adding having the following
first E1EDP02 is going to refer to the PO using qualifier 001, but second E1EDP02 [for tax] s not going to have a qualifier 001. When I do that i get a missing belnr (001) and zeile (001) error.the exact error message is the following
Required field BELNR(001) is missing in segment E1EDP02
Required field ZEILE(001) is missing in segment E1EDP02
Message no. FD070
Now to bypass that, I added the 001 qualifier for the second E1EDP02 [tax part] and now the error that I get is either the PO is duplicated or if i put some dummy PO number, then it says PO cannot be found.
=======
so the question is how is it possible to post  4 items in the idoc , with one being a PO reference and 3 non PO reference using INVOIC01 and IDOC_INPUT_INVOIC_MRM
I also have to add that it is possible to add a non PO items to the MM invoice in MIRO by entering the additional tax lines using the g/l account tab next to the PO reference tab.
