Parsing XML to internal table in SAP without transformation

To parse the XML data into SAP Internal Tables, generally we write Transformation using TCode XSLT_TOOL and need to call that using CALL TRANSFORMATION keyword.

There is another way to do the same using FM: SMUM_XML_PARSE

In this tutorial, we will pick the XML file stored on Application server and parse that file in ITAB. File: Test_Man.xml is stored on Application server path: Test_Man.xml

Application Server File:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<GMInfo>
#<SenderID>987654321</SenderID>
#<ReceiverID>RCV1111111</ReceiverID>
#<MessageID>MID2222222</MessageID>
#<MessageDateTime>20210112000401</MessageDateTime>
#<LineItem>
##<SupplierCode>1</SupplierCode>
##<GINo>90000000000001</GINo>
##<DeliveryNo>8000000001</DeliveryNo>
##<SKUNo>MAT001</SKUNo>
#</LineItem>
#<LineItem>
##<SupplierCode>2</SupplierCode>
##<GINo>90000000000002</GINo>
##<DeliveryNo>8000000002</DeliveryNo>
##<SKUNo>MAT002</SKUNo>
#</LineItem>
#<LineItem>
##<SupplierCode>3</SupplierCode>
##<GINo>90000000000003</GINo>
##<DeliveryNo>8000000003</DeliveryNo>
##<SKUNo>MAT003</SKUNo>
#</LineItem>
</GMInfo>

A mapping structure needs to be created in SE11 according to XML
