How to retrieve “ProductTypeCode” by customer invoice UUID from “InputData.content” in BADI SET_LEGAL_CLS_CODE.absl ?

Hi

How to retrieve “ProductTypeCode” by customer invoice UUID from “InputData.content” in BADI SET_LEGAL_CLS_CODE.absl ?

If anyone have idea about this issue then please suggest me.

I am trying to develop BADI implementation of legal numbering for customer invoices

that I follow “How-To Configure Legal Numbering for Customer Invoices for a Non-Localized Country” document.

URL Reference: https://www.sme.sap.com/irj/sme/solutions?rid=/library/uuid/f0758deb-b6bb-3010-8888-fedbe49079dd

But I found an issue from step number 2.7 (Create new BADI implementation),

I cannot retrieve “ProductTypeCode” by UUID from the “CustomerInvoice” business object when I create customer invoice.

My source code of SET_LEGAL_CLS_CODE.absl.

/*

importABSL;

importAP.CustomerInvoicing.Global;

varinput_uuid = InputData.content;

varqry = CustomerInvoice.QueryByElements;

var_sel = qry.CreateSelectionParams();

_sel.Add(qry.ID.content,"I","EQ","XX*");

varinv = qry.Execute(_sel).GetFirst();

varproduct_type_code;

if(inv.Item.OrderBy(n => n.ID).GetFirst().ItemProduct.IsSet())

{

product_type_code = inv.Item.OrderBy(n => n.ID).GetFirst().ItemProduct.ProductKey.ProductTypeCode;

}

else

{

product_type_code = "";

}

varresult : DataType::BusinessTransactionDocumentLegalClassificationCode;

if(product_type_code == "2" || product_type_code == "6")

{

1. result.content = "32";
2. result.listID = "TW";

}

elseif(product_type_code == "1" || product_type_code == "3")

{

1. result.content = "31";
2. result.listID = "TW";

}

else

{

1. result.content = "36";
2. result.listID = "TW";

}

returnresult;

Thank you in advance.
