Helper Code and SPML Requests
The connector uses various helper functions and SPML requests for CRUD operations. Here is an overview of the key code components:
•	Helper Functions:
o	SerializeToString<T>: Serializes an object to an XML string.
o	GetConfigSettingValue: Retrieves configuration settings.
o	CreateSOAPBody: Creates a SOAP envelope for SPML requests.
o	ParseSearchResponse: Parses SPML search responses.
•	SPML Requests:
o	CreateSPMLSearchRequest: Creates an SPML search request.
o	CreateSPMLAddRequest: Creates an SPML add request.
o	CreateSPMLModifyRequest: Creates an SPML modify request.
o	CreateSPMLDeleteRequest: Creates an SPML delete request.
•	CRUD Operations:
o	PerformCRUD: Executes CRUD operations by sending SPML requests to SAP NetWeaver.
Example Code
Here is an example of a helper function to create an SPML search request:
public static SearchRequest CreateSPMLSearchRequest(string id, string primaryKey, List<string> attributes)
{
    Identifier identifier = new Identifier();
    identifier.Item = id;
    Filter filter = new Filter();

    FilterSet filterSet = new FilterSet();

    List<string> primaryKeys = new List<string>();
    if (string.IsNullOrWhiteSpace(primaryKey))
        primaryKeys.Add("logonname");
    else
    {
        if (primaryKey.Contains(' '))
            primaryKeys.AddRange(primaryKey.Replace(" ", "").Split(' '));
        else
            primaryKeys.Add(primaryKey.Trim());
    }

    object[] obj = new object[primaryKeys.Count];
    ItemsChoiceType[] itemsChoiceTypeArray = new ItemsChoiceType[primaryKeys.Count];
    int pkIndex = 0;
    foreach (string pk in primaryKeys)
    {
        AttributeDescription attrDesc = new AttributeDescription();
        attrDesc.name = pk;
        obj[pkIndex] = attrDesc;
        itemsChoiceTypeArray[pkIndex] = ItemsChoiceType.present;
        pkIndex++;
    }

    filterSet.Items = obj;
    filterSet.ItemsElementName = itemsChoiceTypeArray;
    filter.Item = filterSet;
    filter.ItemElementName = ItemChoiceType.and;

    AttributeDescriptions[] attrs = new AttributeDescriptions[1];
    if (attributes != null && attributes.Count > 0)
    {
        AttributeDescription[] attributeField = new AttributeDescription[attributes.Count];
        int index = 0;
        foreach (string attribute in attributes)
        {
            AttributeDescription attributeDescription = new AttributeDescription();
            attributeDescription.name = attribute;
            attributeField[index] = attributeDescription;
            index++;
        }
        AttributeDescriptions attributeDescriptions = new AttributeDescriptions();
        attributeDescriptions.attribute = attributeField;
        attrs[0] = attributeDescriptions;
    }

    SearchRequest searchRequest = new SearchRequest();
    searchRequest.searchBase = identifier;
    searchRequest.filter = filter;
    searchRequest.attributes = attrs;

    return searchRequest;
}
