How do I implement BP-to-Customer and BP-to-Vendor tax mapping in the CVI custom mapper BAdI?
Implement IF_EX_CVI_CUSTOM_MAPPER so BP tax numbers are mapped to customer or vendor tax fields using country- and category-specific rows from ZMDG_BP_MAP_VAT, then set the corresponding X-structure flags. The customer path also derives ZZWWIBC from BRSCH when available.
SOLUTION SUMMARY · SHORT ANSWER
Implement IF_EX_CVI_CUSTOM_MAPPER so BP tax numbers are mapped to customer or vendor tax fields using country- and category-specific rows from ZMDG_BP_MAP_VAT, then set the corresponding X-structure flags. The customer path also derives ZZWWIBC from BRSCH when available.
Use IF_EX_CVI_CUSTOM_MAPPER in class ZCL_MDGBP_CVI_CUSTOM_MAPPER to translate BP tax numbers into customer or vendor tax fields during CVI conversion. The implementation reads the first BP address to derive the country filter, selects mapping rows from ZMDG_BP_MAP_VAT by object category (CUST or SUPL), matches BP tax types against ZZTAX_CAT, and fills the target field named in ZZFIELD_NAME while also updating the X-structure.
Process flow
- Implement or activate class ZCL_MDGBP_CVI_CUSTOM_MAPPER for IF_EX_CVI_CUSTOM_MAPPER.
- Read BP address data and derive the country from the first address entry.
- Select ZMDG_BP_MAP_VAT rows for ZZBP_CAT = 'CUST' or 'SUPL' and the country-specific tax category pattern.
- Read I_PARTNER-CENTRAL_DATA-TAXNUMBER-TAXNUMBERS and match DATA_KEY-TAXTYPE to ZZTAX_CAT.
- Write TAXNUMBER or TAXNUMXL into the field named in ZZFIELD_NAME using dynamic component access.
- Set the corresponding X-structure field to abap_true.
- For customer mapping, derive ZZWWIBC from BRSCH using ZCL_MDG_CUS_APPROVERS=>GET_IBC_FROM_TED.
- Leave the contact/relation and reverse-mapping methods as no-op RETURN methods unless business rules require otherwise.
