Implementing CL_BSP_BP_TAX_NUMBERS for data binding

Question

Hi everyone,
I've got to use the BP tax number in IC WC. I've seen that we've got this class: CL_BSP_BP_TAX_NUMBERS. But i don't know how to implement this class since i create a page attribute that is ref to this class and a controller attribute that is also ref to this class.
When i define the input fields in the page:
<crmic:gridLayoutCell columnIndex="1" rowIndex="<%=lv_r3 + 2 %>" colSpan="3"><crmic:label design = "label"
                     for    = "//BP_TAXDATA/GTTAXINITIAL.TAXNUM"
                     text   = "<%= otr(ZCRM_IC/TaxNum) %>" /></crmic:gridLayoutCell>
      <crmic:gridLayoutCell columnIndex="4" rowIndex="<%=lv_r3 + 2 %>" colSpan="5"><crmic:inputField id = "NIF"
                          width     = "100%"
                          maxlength = "10"
                          value     = "//BP_TAXDATA/GTTAXINITIAL.TAXNUM" /></crmic:gridLayoutCell>
I get an error.
Can anybody help me. How should i implement this class?
Best Regards

Answer 1

Hi,
In that case what I can suggest is to define ur Z class of which CL_BSP_MODEL is super class.
Now in friends tab specify CL_BSP_BP_TAX_NUMBERS and it will be accesible now to you.
Do revert back if u need any assistance.
Cheers
