Modify data type for HSN and SAC reporting types for India Localization

Hello,

For India Localization we are defining the HSN and SAC codes in the seeded reporting types GST_HSN_CODE and GST_SAC_CODE_ITEM however we noticed these seeded reporting types have a data type of numeric and if we have alphanumeric values for HSN and SAC codes the form does not let us enter those .So where can we modify the data type for GST_HSN_CODE and GST_SAC_CODE_ITEM from numeric to alpanumeric?

Thanks

Rahul
